The Oil-filled Grid: Communications

Early January Nor'Easter

Oil on the Grid

About two weeks ago, I wrote a blog post The Northeast Grid and the Oil. This described our early-January polar weather, and how Northeastern power plants could not get enough natural gas in the below-zero weather. Homes had priority for natural gas delivery, and plants that could use oil switched from natural gas to oil.

As a matter of fact, the oil stocks were also getting depleted.

I want to update the cold-snap story with some other posts. The general public doesn't read my blog, so I did some outreach. I wrote an op-ed about the grid for my local paper, the Valley News.  The op-ed was printed on the front page of the Sunday Perspective section on January 28, and has been shared around 200 times on Facebook. Oil Kept the Power Grid Running in Recent Cold Snap.

Why were people so interested in the article?  Because a secure electric supply is an important part of personal safety during extremely cold weather.  Most home furnaces require electricity to spread the warmth into the household. People who have chosen heat pumps are also dependent on reliable electricity.

Nuclear plants and pipelines and controversy, oh my!

There were more articles on the situation, of course, not just mine.  Actually, I think there were too few articles.  Nearly running out of oil when you can't get gas---this can be a major deal during severe winter weather! I will point out some interesting articles, and I hope that people who read this will send links to a few more.

Rod Adams post described the "sobering statements" made by the grid operator about oil supply, and the weird statements made by nuclear opponents.  (Pilgrim should have shut down before the storm? Really?) He shares some graphics from ISO-NE on the weak performance of solar panels during the days of the crisis.  He also discusses Pilgrim going off-line, and whether that could have been prevented. As usual, his post has an active and informed stream of comments. Performance of the New England power grid during extreme cold Dec 25-Jan 8, at Atomic Insights blog.

Meanwhile, over at Forbes, several columnists were commenting on the situation.
Jude Clemente wrote What Happens When You Don't Build Natural Gas Pipeline
David Blackman wrote Amid Deep Freeze, New Englanders Can 'Thank' N.Y. Gov Cuomo For Their High Energy Bills
Christopher Helman wrote Natural Gas Demand Hits Record As Cold Bomb Targets Northeast

Over WBUR radio, Bruce Gellerman has a fascinating seven minute segment on how the power plants actually operated during the cold snap, including an interview with a manager of a peaker plant that runs about 800 hours a year. Do We Need More Natural Gas Pipelines?

There's a lot of controversy built into all these articles. The role of nuclear.  The need (or not-need) for more natural gas pipelines. Will new emissions regulations make handling the next cold snap much harder? Did renewables make a great contribution during the cold snap?  Or not?

The Electric Supply

A steady electric supply is hugely important to winter safety. In my opinion, it should not be such a subject of controversy.  My hope is that  reason will prevail, and we will have the nuclear plants, pipelines and energy security that we need.

Why Electricity Costs Spiked in New England: My Op-ed

Why Are the Rates Rising?

A Valley News "Forum" letter writer was speaking for many recently when he asked about the huge electric rate increases this winter and the paltry explanations for them. David C. Montgomery of Hanover said his electricity bill had increased by 72 percent, even as petroleum products have dropped in cost. “All we have seen,’’ he wrote, “is a rather unconvincing claim about the need for more natural gas pipelines in New England and a series of what seem to be diversionary workshops on insulation.”

His letter states the problem succinctly. Oil prices are down. Gasoline prices are down to levels not seen for years. Natural gas prices are still low. “The need for more pipelines” does seem a rather weak claim, compared to the cheapness of the commodity carried in them. Also, why would we need more pipelines now, when we didn’t need them five years ago? The demand hasn’t changed that much.

The answer is that the grid itself has changed in our region. Power plants have been retired: Salem, Mt. Tom, Vermont Yankee. When coal and nuclear plants shut down, existing gas plants run longer and use more fuel, to make up for that power. More gas-fired plants are also being planned for the future.

More Gas Needed

Around 2000, about 15 percent of New England’s electricity was made by burning natural gas. Gas was expensive, and used only during times of peak demand. The rest of the time, electricity was supplied by a mixture of coal, nuclear, oil and hydro. Back then, with only 15 percent of electricity coming from natural gas, pipelines to the Northeast were adequate.

Now, the price of natural gas has fallen, and nearly half of our electricity demand is met with the newly inexpensive natural gas. With increased demand, the pipelines are no longer adequate. Particularly during very cold weather, when homes use more natural gas for heating, there isn’t enough available for power plants.

Last year, when temperatures plummeted and natural gas ran short, power plants burned oil, diesel and even jet fuel. The price on the grid went up as utilities bought power produced with more-expensive fuels. Last year, bulk electricity prices often soared past 40 cents per kWh (kilowatt hour) during times of high demand. (It’s usually 3 to 8 cents per kWh.) You can track realtime prices on the grid operator site (ISO-NE) on the Web.

Other costs also go up when power plants retire, but these aren’t so easy to track. For example, capacity payments go up. So far, I have described prices for kWh . . . that is, for power produced. There’s also something called a “capacity payment”: a payment for a plant to be available to produce power. The capacity payment auction takes place three years in advance. In 2013, the auction yielded $1 billion for power plant operators. Then a number of plants retired. With more scarcity, the 2014 auction brought $3 billion to plant operators. These billions are not as visible as the “price on the grid,” but the money comes from ratepayers and raises everyone’s cost of electricity.

Winter Reliability

Then there’s the reliability issue. The grid operator will do whatever it must to ensure reliability. For the past two winters, our grid operator has run “winter reliability programs” and frankly, that program saved us last winter. Last winter, the operator paid about $70 million to power plants that could burn oil. The plants used this money to stock up — with a supply on site, they had fuel available when they were called upon. Indeed, when gas-fired plants could not get gas, the oil-burning plants went online.

Last year, the Winter Reliability Program cost $70 million in the Northeast. This year, it is budgeted at $80 million. These multimillion dollar programs get translated into our winter power bills and winter price rises. However, there is a bit of hope for the future. This has been a milder winter, with low oil prices. To date, the grid’s Winter Reliability Program has spent far less than last winter, and that is a hopeful sign for the future.

Renewables

What about renewables? I will not focus much on renewables or their costs, because they are a very small portion of the electricity supply. I have been watching the hourly fuel supply on the grid rather closely, and wind has never been more than 2 percent of the supply. Renewables, including biomass and refuse, are about 6 percent of the supply. Renewables are not the cost-drivers on the grid.

Solutions, Maybe

I’ve explained the reasons for recent price rises, but do I have a solution? Well, a partial solution, maybe. First, I believe in conservation, and I just invested a great deal in improved insulation for my house. (And I want to thank Efficiency Vermont for picking up part of the cost.) To me, workshops on insulation are not merely diversionary. They are terribly important.

Being in favor of insulation is about as controversial as favoring real maple syrup. My second point is a little more controversial. Supposedly, we need more pipelines because gas is the fuel of choice . . . now. It’s abundant and cheap. But I don’t think it will remain cheap. Should we be building more pipelines because of low-priced gas? I am not sure. If the price of gas goes up, the pipelines will not be fully used.

Pipeline Pig Launcher
Wikipedia
Instead of more pipelines, I think we need a diversified grid. If we choose, we can build more renewables with a diversified grid, just as we can build them with a mostly-gas grid. And with a diversified grid (yes, I mean keeping our nuclear, coal, oil, Hydro-Quebec power as well as gas), we won’t have all our eggs in one basket.

If we are going to have a heavily natural-gas grid, we could keep our costs more stable (for now) and our grid more reliable by building more gas pipelines. But I think it would be better to choose conservation and grid diversity. With that, perhaps we could have reliability and prevent further drastic price rises in the future.

This op-ed appeared in the Valley News Sunday, January 18, 2015. I have edited it slightly (such as explaining that "Forum" is the Valley News letters section.)

It was illustrated with a very nice picture of Vermont Yankee.  The op-ed has appeared other places, also, including Vermont Digger, where it began to have a lively comment stream, but then a well-known anti-nuclear activist took over the comments.

I don't think it is worth duking it out with trolls, especially after they insult me.  For example, this line: Ms. Angwin still fails to acknowledge, however, that her basic premise is simply false: it is simply not a “fact that electricity prices are soaring all over the region.”  

In cheerier news about this op-ed, Don Kreis wrote a letter to the Valley News about my op-ed. Kreis is a former professor at Vermont Law School and a hearing officer with the Vermont Public Service Board. (His letter is not on the web, so I can't link to it.)  I am proud to quote the first sentence of Kreis's letter:

Meredith Angwin of the Ethan Allen Institute is a rock star among energy analysts, and she hits the right chord by blaming the recent run-up in electric rates on our big regional embrace of natural gas as a generation fuel.

Why Electric Rates Are Rising: My Op-ed

Reddy Kilowatt
From Wikipedia
New England electricity is too dependent upon natural gas-fired power plants. And we are about to pay a lot for that dependence.

In recent days, several New England utilities have announced major price rises for electricity. In Massachusetts, National Grid said that its customers can expect a 37 percent rate increase in November. Liberty Utilities in New Hampshire announced that there will be a 50 percent rate increase, and Unitil, which serves Massachusetts, Maine and New Hampshire, announced a price rise that will add over $40 a month to the average home electricity bill. These companies explained that the rate increases are due to the increasing cost of power on the grid.

Why is the grid cost increasing? Part of the reason is supply and demand. Supply has decreased. Vermont Yankee (nuclear) and Salem Harbor in Massachusetts (coal) are shutting down and will not be available this winter. During the high demand resulting from the polar vortex in early 2014, New England needed about 20,000 megawatts of power. The grid barely scraped up enough to meet the demand. This year, 1,000 megawatts, or five percent of that power, is going off-line, and no new power plants have been built.

But perhaps a bigger problem is that the New England grid is far too dependent on natural gas. During the polar vortex cold snap, which affected all of New England, many natural gas power plants could not get enough gas to operate. It was being used to heat homes. New England is often described as “pipeline-constrained”: There are not enough pipelines for the natural gas we need.

The grid operator, ISO-NE, a nonprofit company, is responsible for ensuring a reliable electric supply on the New England grid. The way the grid operates is that some plants keep running steadily all the time. The steady-operation plants are nuclear, coal and some of the natural gas facilities — basically, plants that operate on a steam cycle. When demand is higher than these plants can supply, it is met by putting more gas-fired plants into service. However, last winter, many gas-fired plants could not operate.

ISO-NE foresaw this natural gas supply crunch and had a “winter reliability” program in place. It paid $70 million to oil-burning power plants to keep oil available to burn. This was a “capacity” payment. That is, the plants were paid just to have oil on hand. (This payment also increased our electric bills.) But during the polar vortex power crunch, the oil was not enough, and some jet fuel was also burned to make power. In other words, over-dependence on natural gas led to expensive alternatives: oil and jet fuel. Using these fuels caused major price increases.

Also, even without the crunch, the price of natural gas itself has doubled since its low point in 2012.

The two issues (supply and diversity of fuel sources) are going to intersect again this winter. With two power plants closed, a cold snap this winter will require more oil and jet fuel than was required last winter. Utilities are getting their rate increases lined up to deal with the coming price spike.

What about my own local utility? I live in Vermont, and Green Mountain Power (GMP) told the press recently that because of its “efficiencies” it has lowered prices and will keep them low.

I do not believe prices will stay low in Vermont. GMP is subject to the same factors that affect the other utilities. It buys much of its power on the same markets. GMP also has large contracts with Hydro Quebec. Unfortunately, these are “market-follow” contracts. When the market price rises on the grid, Hydro Quebec will also raise the price that it charges GMP. Back in 2010, I wrote blog posts on how the new market-follow contracts were “a bad deal with Hydro Quebec.” This winter, I suspect we will find out just how bad a deal they are.

What about renewables? For many reasons, renewable build-out is not happening very quickly. As of last year, less than 10 percent of Vermont’s in-state electricity generation was by renewables, not counting hydro.

Also, renewables are generally paired with natural gas (gas-fired plants are turned on when the wind dies down or the sun sets). So renewables are not going to be much help right now.

I was recently elected to be on the coordinating committee of the Consumer Liaison Group of ISO-NE. Along with 120 people from all over the Northeast, I attended its quarterly meeting in September. Everyone there seemed to have a tale of when the big price rises would hit their local utilities. Many are planning major price increases in January 2015.

What shall we do about these price spikes? Just as in our private lives, diversity is important. I think we need to be willing to accept diversity on the grid: nuclear plants and coal plants. Natural gas is an excellent fuel, but it seems to be the one and only fuel acceptable to many people. However, what is happening on the grid right now is a classic illustration of the old saying: “Don’t put all your eggs in one basket.” Our grid is close to just one basket right now (over 50 percent natural gas). The winter is coming, and power will be expensive if any eggs drop.

Exporting Our Carbon Problems: Op-Ed by Meredith Angwin

Exporting our carbon problems
The EPA takes a flawed state-by-state approach to greenhouse-gas policy

The Environmental Protection Agency recently issued a proposed plan for greenhouse gas mitigation: the electricity sector must cut greenhouse gas emissions by 30 percent by 2030. The rules are set on a state-by-state basis.

I am in favor of cutting carbon emissions, but the EPA plan is arbitrary, ineffective, and political. The abatement standards are plain backwards: states that already have a clean-energy mix have to do a higher percent of abatement than states that burn large amounts of coal.

EPA’s criteria for reduction goals are, frankly, opaque, including complex “building blocks” for reduction. To decide on the level of reduction required, the EPA looked at various issues, such as coal plants that might be already slated for retirement, and whether a state has natural gas available.

Per kilowatt hour of electricity produced, burning coal produces twice the carbon dioxide as burning natural gas. Logically, the EPA would require greater cutbacks in coal-burning states.

That did not happen.

For example, West Virginia generates 90 percent of its electricity from coal — and it must cut its carbon dioxide emissions by 19 percent.

In contrast, New York state has a pretty clean energy mix and, according to state profiles compiled by the U.S. Energy Information Administration, gets less than 10 percent of its electricity from burning coal — and it must cut its carbon emissions by 44 percent.

With this sort of regulation, it is no surprise that New Hampshire, which gets less than 10 percent of its electricity from coal, must cut carbon emissions by 46 percent.

* * *
Flag of Vermont
VERMONT, on the other hand, is a poster child for a low-carbon state. Vermont and the District of Columbia use very little fossil fuel to make electricity, so they are the only two states (well, state and district) that don’t have to submit a plan for carbon abatement in the electricity sector.

However, more than 70 percent of the electricity generated within Vermont comes from Vermont Yankee, a very low-carbon electricity supplier. When Vermont Yankee shuts down at the end of the year, Vermont will be importing energy from states with more carbon-heavy profiles.

Will it cease to be a shining example of a low-carbon state?

No. According to the EPA, Vermont will still be a low-carbon state as long as it doesn’t generate high-carbon electricity in state.

EPA regulates carbon according to power actually generated within the state, not by power purchase contracts. If other states are burning more fossil fuels to supply Vermont, the carbon mitigation rules will be their problem, not Vermont’s problem. Vermont will have exported any possible compliance problems.

* * *
That brings us to New Hampshire, which has to cut back 46 percent of its carbon emissions. With more than half of its electricity coming from nuclear and less than 10 percent from coal, cutting back to that degree might be hard.

However, the state is in the Regional Greenhouse Gas Initiative (RGGI) with Vermont and other states. New Hampshire is already cutting back its carbon emissions to meet RGGI requirements, and it hopes these cuts will be enough to meet the EPA requirements also.

Flag of New Hampshire
In case New Hampshire’s RGGI cutbacks are not enough, a Concord Monitor story reported, the state is looking at whether the EPA emission caps could be set as a combined target for all the RGGI states, thereby possibly involving Vermont in the cutbacks, in a manner that has yet to be determined.

However New Hampshire meets its requirements, it won’t have to do so very quickly. Starting now, there’s a one-year period for public comment on the EPA plan, followed by another year (or more) for the states to design their mitigation plans.

According to a Bloomberg New Energy Finance white paper, state plans are due by June 2017 and multi-state plans are due by 2018. It sounds as if New Hampshire might choose to participate in a multi-state plan. In such a scenario, New Hampshire’s choices might also affect Vermont’s status. Maybe.

* * *
The whole thing is unreasonably complicated. It is no wonder that many commentators expect a raft of lawsuits.

You can also think satire: The Onion (a humor website) describes the situation with this headline: “New EPA Regulations Would Force Power Plants to Find 30% More Loopholes by 2030.”

Or you can think confusing: The Bloomberg New Energy Finance white paper is entitled “EPA’s Clean Power Plan: 50 Chefs Stir the Pot.”

Or you can think political: The EPA clearly made major concessions to the coal states in the state-by-state requirements.

At any rate, when rules require a state that doesn’t produce much carbon to cut its production drastically while allowing comparatively minor cutbacks to a state that produces a lot, it’s hard to justify this policy as “carbon mitigation.”

* * *
In the early part of my career, I worked on finding abatement methods for nitrogen oxide pollution:
reducing these emissions was required under the Clean Air Act.

Brownish NOx smog at the Golden Gate Bridge
Credit to Aaron Logan at Wikipedia
Nitrogen oxide emissions are the cause of the dirty brown color of photochemical smog, and they are caused by high-temperature combustion. At a high-enough flame temperature, the air burns itself, uniting nitrogen and oxygen in the air to make nitrogen oxides. This happens in cars and in almost all fossil-fired power plants.

If an area had particularly dirty air, it had to make more drastic cutbacks on pollution. For example, California cars eventually had to have more pollution controls on nitrogen oxide emissions.

Comparing these new carbon rules to my experience regarding nitrogen oxide pollution, I have a hard time wrapping my mind around the idea that an area that produces lots of carbon dioxide has to do less abatement than areas that produce little.

I do not mean to imply that in those good old days, back when I worked on nitrogen oxide pollution, nothing was political. Of course things were political. States and utilities sued one another, they sued the EPA, and so forth and so on.

However, the nitrogen regulations did not start as political: they started as general rules, and then various interest groups attempted to get changes made. In contrast, the recently issued carbon rules are strongly political from the start.

In my overview of the EPA plan, I sadly admit that I think The Onion is right: there will be 30 percent more loopholes by 2030.

The Proposed Entergy Settlement is Good for Vermont

The Proposed Settlement

The state of Vermont and Entergy Corporation have been battling each other for years, but the two parties reached an agreement in December about the future of Vermont Yankee. Entergy has owned and operated the 42-year-old nuclear plant in Vernon since 2002. When Entergy announced plans to close the plant by December 2014, the state, which has passed laws aimed at preventing the plant from operating, seemed surprised. It also lost some negotiating leverage. Even so, the settlement, which the Vermont Public Service Board must still approve, is a good deal for Vermont — better than I thought possible. Let’s take a look its four main points: the Certificate of Public Good; pending lawsuits; payments; and decommissioning.

The Certificate of Public Good: In 2012, the Nuclear Regulatory Commission renewed Vermont Yankee’s federal license for 20-year-period, through 2032. However, to keep operating for that period, the plant also needed state approval, specifically a Certificate of Public Good from the Public Service Board. The Shumlin administration vigorously opposed granting such a certificate, and used the state approval process to try to force the plant to shut down when its original license expired. Now that Entergy has amended its petition to operate only through the end of this year, not through 2032, the state will be on Entergy’s side before the Public Service Board.

Lawsuits: The main federal lawsuit hinged on whether Vermont interfered in the federal regulation of nuclear safety. In both district court and in appeals court, Entergy won its case, arguing that the Legislature attempted to regulate nuclear safety when the state Senate voted in 2010 to deny the plant a certificate of public good. Nuclear safety, like airline safety and drug safety, is regulated at the federal level. Though Entergy won its case, both Vermont and Entergy conceivably had grounds to appeal to the U.S. Supreme Court. Now, according to the agreement, neither side will appeal. I suspect both sides breathed a sigh of relief.

The agreement also settled another lawsuit about a new “generation tax.” The state had raised the generation tax on Vermont Yankee to $12 million a year. This is a tax paid by Entergy for every kilowatt-hour that the plant generates. However, the higher tax rate applied only to power plants that were built after 1965 and were larger than 200 megawatts! Of course, there’s only one such plant in the state, and Entergy quite reasonably felt targeted. In the agreement, Entergy agreed to drop this suit and to pay the $12 million for 2014.

Payments: Entergy agreed to pay more than the new generation tax. In 2015, the plant won’t be generating any power, so Entergy won’t be required to pay the generation tax. However, Entergy agreed to pay the state $5 million in 2015, to help the state as it deals with the loss tax revenue Vermont Yankee generated. Entergy also agreed to other relatively short-term payments: a payment of $5 million to the Clean Energy Development Fund, and a further payment of $2 million a year for five years to help Windham County adapt to the plant closing.

In his address on the state budget, Gov. Peter Shumlin mentioned “one-time payments” from Entergy as part of his plan to close the state’s budget gap.

The state appears to have won the financial negotiations. However, the plant closing means that $60 million a year in payroll will disappear from the local economy. These payments hardly begin to close that gap for Vermont and neighboring states. As I have said before, it would have been far better if the plant remained open. Some people say that decommissioning will be a similar boost to the local economy, but it won’t be. Not in the next few years at least.

Decommissioning: This has been, and remains, the most difficult and contentious part of the agreement. When Entergy bought the plant in 2002, the agreement it signed with the state allows Entergy to use a delayed decommissioning plan called SAFSTOR, approved by the NRC. With
SAFSTOR, decommissioning can take up to 60 years but it could also be completed sooner. The state wanted to decommission the plant sooner, much sooner  —  immediately, as a matter of fact.

However, in the course of the negotiations, I suspect the state learned some facts about decommissioning. Decommissioning cannot start for six or more years after the plant is closed. After the plant is shut down, the last fuel from the reactor is placed in a spent-fuel pool. This fuel must cool in the pool for five years before it can be removed and put into dry-cask storage. In plants such as Vermont Yankee, the fuel pool is in the same building as the reactor.

You can’t begin tearing down the building while the fuel pool is still in use. So there has to be at least a five-year delay between plant closing and the beginning of major decommissioning work. Therefore, there will be a gap of several years in the economic activity around the plant. In the agreement, Entergy agreed to move the fuel from the pool in a timely fashion. In the press conference about the recent agreement, Shumlin said that all fuel bundles should probably be moved into dry cask storage within about seven years.

Maine Yankee dry cask storage
Other major decommissioning work can begin after the fuel is moved to dry casks. The decommissioning fund is around $580 million now, and decommissioning is estimated to cost between $600 million and $1 billion. Entergy agreed to start full decommissioning when the fund is large enough to to pay for the job. (Federal rules for SAFSTOR stipulate that owners can wait up to 60 years to complete decommissioning, no matter how big the fund.) Entergy also agreed to put $25 million into a separate fund for “greenfielding” the site. Greenfielding generally involves excavating, grading and seeding.

The Next Steps

Of course, not everyone is happy with the agreement. Opponents loudly insist that decommissioning must start immediately (it can’t), and others worry that it will take years for Entergy to have enough funds to start decommissioning. The definition of “greenfielding” is also contentious.

Even so, the agreement is a major step forward in what has been a hard battle between Vermont Yankee and the state. Both are arguing in favor of this agreement before the Public Service Board. That’s quite an unexpected development. Either side could withdraw from this agreement if the Public Service Board does not approve it by March 31, however. The board is now considering this plan, and the public comment period is still open. At the PSB website, you can read docket 7862 and write your comments. I encourage you to do so.

Here is a direct link to the comment form on this docket.

When reading docket 7862, you will note that there are two major document filings: the Memorandum of Understanding and the Settlement Agreement.  The Settlement Agreement is the agreement between Entergy and the state agencies, while the Memorandum of Understanding is the part of the Settlement Agreement that lies within the jurisdiction of the Public Service Board. The Board will rule on the Memorandum, but the Settlement Agreement was filed for informational purposes.

Vermont Yankee's Closing Will Hurt Vermont

The Plant Will Close

On Aug. 27, Entergy announced that Vermont Yankee would be shuttered in the fall or 2014, when its current fuel load is finished producing power.

Entergy’s decision elicited a variety of reactions. Some regarded this as a great victory and were practically dancing in the streets. I was among those who were upset and depressed by the news. But I suspect that most people were somewhere in the middle. They thought, well, Vermont isn’t using Vermont Yankee power anyway, so it shouldn’t make much of a difference.

It does. Vermont Yankee’s closing will affect everyone in Vermont. It will make our electricity more expensive, more fossil-fuel based and less reliable.

Vermont utilities are using Vermont Yankee power now. They’re not officially buying Vermont Yankee power, but “using” power and “buying” power are different. Power use has to do with physical structure — where power plants, transmission lines and users are located. “Buying” power is about power contracts. A utility can choose to “buy” power from far away, but it will continue to use the power from the local generators. For example, when Green Mountain Power bought power from Seabrook instead of from Vermont Yankee, no power lines needed to be constructed. When a major supplier of regional power is lost, it must be replaced, regardless of who’s buying it.

So when Vermont Yankee closes, people in Vermont will have to get actual power from other sources. Can they get this power? The short answer is yes. Vermont Electric Power Co. (VELCO) manages the state transmission systems. VELCO was concerned that Vermont Yankee might close. Between 2010 and 2013, it invested $30 million in new lines and substations to bring replacement electricity to Vermont.

The Replacement Power

What will the new power sources be? Despite the Vermont Comprehensive Plan, very little will come from renewable sources. Building renewables is a slow, expensive, land-intensive job. Vermont Yankee generates 620 megawatts of power and is well-connected to the grid. In contrast, the Lowell Mountain wind project produces 64 MW and has difficulty getting on the grid. Rep. Tony Klein, a strong advocate of wind energy, said recently that he expects no more wind farms to be built in Vermont for another 10 to 15 years.

When Vermont Yankee goes off-line, Vermont will get its power from outside Vermont: either power supplied by the regional grid, ISO-NE, or hydro-power from Canada. With Yankee closing, much of the power on the grid, especially the spot market power, will be gas-fired and its price is due to go up. Power supplied under contract by HydroQuebec follows that spot price. Before, when gas prices went up, Vermont Yankee could underbid the gas prices, and supply many megawatt-hours at a lower price than gas. But without Vermont Yankee, gas prices will determine the price of almost everything on the grid.

Natural Gas and Some Oil

Industrial Gas Turbine
Our local grid power is already overdependent on natural gas. Right now, 52 percent of the power on the grid is produced from natural gas, and it will be a higher percentage when Vermont Yankee closes. ISO-NE considers gas dependence a “key strategic risk” for New England. The area is vulnerable to supply disruptions and price changes for this commodity.

Let’s start with supply disruptions. We had a natural gas supply crisis during the January 2013 cold snap. Although many in New England heat their homes with natural gas, the limited gas lines serving the region make for an inadequate supply. In cold weather, when domestic demand for gas spikes, those customers receive priority, and the power plants can’t get enough gas. During that cold snap, the grid would attempt to summon the help of a gas-burning power plant, and the plant would answer: “Sorry. Can’t go online. No gas.”

This year, ISO-NE started a “Winter Reliability Program” to address this problem — by using oil. ISO-NE has set aside $75 million to keep (mostly) oil-burning plants at the ready. That’s right, the grid is paying $75 million to have oil-burning plants keep oil onsite. (This is a “capacity” payment; the plants will be paid separately when they actual make power.) ISO-NE is ensuring reliability, but at a high dollar cost and a high cost in fossil-fuel use.

Without Vermont Yankee, more power will come from gas plants, but they will still be supplied by the same set of pipelines. Unless new pipelines are built quickly, an unlikely event, it will take less of a cold snap to activate the “we can’t get gas for our power plant” situation. In that case, more oil will be needed for back-up.

Price also matters, and once again, the problem is a lack of pipelines. Fracking has made a lot of gas available, but New England’s access to it is limited. The Federal Energy Regulatory Commission, which tracks national supply and demand, published a market assessment in October that reported that gas prices are relatively stable in most of the country, except in New England. In other regions, gas prices charged last winter and for futures contracts written on the coming winter are around $4 per MMBTU (1 million BTUs). In New England, natural gas prices last year were $6.60 MMBTU, but the futures price for the winter of 2014 is soaring to $11.75. Electricity prices in this area are also expected to rise, since electricity prices customarily track gas prices.

Canadian Hydro--only a very partial solution

What about getting more power from hydro plants in Canada? This will work … partially. Depending on how much electricity we import, new transmission lines may well be needed. Some of these lines are already being planned. We should also note that Canadian power is unlikely to shield us from price rises on the grid. Under the new HydroQuebec contracts signed around 2012, the price HydroQuebec charges will fluctuate; it will move according to the market price on the grid, which itself follows natural gas prices.

Ice Storm of 1998
In this case, we will be actually moving more electricity from Canada, not just writing contracts. Electricity carried long distances is also liable to disruptions. In 1998, an ice storm devastated HydroQuebec’s power lines, causing widespread, lengthy power outages. This could happen again, but let’s look at a more recent and more mundane supply disruption.

During that same cold snap last January, HydroQuebec exported only about half of the usual amount of electricity to the U.S. Why did it cut back just when the power was most needed?

Quebec law requires HydroQuebec to supply inexpensive electricity to “legacy” customers within the province. The needs of those customers must be met, and at a retail price of around 3 cents per kWh. Therefore, many people in Quebec heat with electricity. In a cold snap, the Quebec heaters go on, and HydroQuebec has less power to send to us. HydroQuebec hates this, but has no choice.

Cold Weather and Reliability

Even with Vermont Yankee running, Vermont and New England were overly dependent on natural gas. Without Vermont Yankee, the problems will get worse,. Our dependence on natural gas and on Canada sets us up for a perfect storm of increased power prices — and it won’t take a monster storm to trigger it. Cold weather itself will do a fine job.

Where Vermont Power Will Come From After Vermont Yankee

Rainfall in U S during ice storm
Does not include rainfall Jan 4 and 5
On Sunday, the Valley News published my op-ed Yankee's Closing Will Hurt Vermont. 

I always enjoy having an op-ed in the my local Sunday paper.  I hope you read it. It's about the probable effects on Vermont when Vermont Yankee closes.

Factors Affecting Vermont Electricity 

As I wrote in the op-ed:

Vermont Yankee’s closing will affect everyone in Vermont. It will make our electricity more expensive, more fossil-fuel based and less reliable.

I explained the factors that will affect our power supply and pricing after Vermont Yankee closes.  Specifically:

  • The plant will not be replaced by renewables.  Wind turbine construction in Vermont is practically at a standstill, for example.
  • Our power will come from outside Vermont, and be subject to various sorts of interruption, including too few natural gas supply lines, ice storms, and HydroQuebec needing to use its electricity in Quebec during a cold snap.
  • The electricity price will follow the grid price of natural gas.  According to FERC, the New England price of natural gas is set to rise substantially (from $6.60 MMBTU to $11.75 MMBTU).  In the rest of the country, the price of natural gas is set to remain stable.
  • Grid payments of $75 million to oil-burning plants (the ISO-NE Winter Reliability Program) will be rolled into our electricity costs.

What About the People at Vermont Yankee?

Several people asked me why I didn't mention the people at Vermont Yankee, the effect of the plant closing on the local economy, the effect on the state economy, the effect on the state taxes?  

There's a simple reason.  I live about sixty miles north of the plant, and I think people in this area don't care very much about southern Vermont.  People here generally commute across the bridge to New Hampshire, where they work at Dartmouth College, Dartmouth Medical Center, and many high-tech industries spawned by Dartmouth (for example, HyperTherm).  

People here care where their electricity comes from. They care about reliability and about environmental impact.  They care somewhat about their electric bills.  My own feeling is people here don't care that much about what happens to Brattleboro or Vernon. They are insulated from many aspects of the Vermont economy through their jobs in New Hampshire.

Therefore, for my local paper, I wrote about things that affect all of Vermont: where our electricity comes from, how reliable it is, how fossil fuels will be used to produce our electricity, and how expensive electricity may become.

The Op-Ed

For an op-ed, Yankee's Closing Will Hurt Vermont was  very data-dense!  Sometimes I wondered--where was the "opinion" part?  Why did I write it this way?

Still, it was fun to write, and I plan to reprint it on this blog in a week or so.  

However, I always like to have people access the op-ed at the newspaper for a few days before I begin putting it on my own blog.  I hope you enjoy the article.

----
P.S.  Just came across an article in a Boston business journal which says that Boston should expect a 20% percent price rise in electricity this winter, for some of the same reasons I discussed for expecting price rises in Vermont.

Wind Turbine Construction Slows: Guest post by Willem Post


This guest post by Willem Post appeared as a letter to the editor in our local paper, the Valley News.  (I have a subscription, but the letter may be behind a paywall for most people.)  Post has allowed me to republish it in this blog.

--------

To the Editor:

Things are looking up. There is a major slowdown in wind turbine construction all over the U.S.

In the first quarter of 2013, only 1.6 megawatts of wind turbine capacity was built and in the second quarter, zero was built. The main reason is the expiration of the Section 1603-c program at the end of 2012, which gave federal cash grants of about 30 percent of the project capital cost to wind turbine project developers.

This infusion of cash grants to Big Wind under the American Recovery and Reinvestment Act of 2009 changed the economics of the industry overnight. Projects that made no economic sense became viable with the cash grant (Lowell Mountain, etc.) In many cases, applications were rushed to take advantage of the cash grants before deadlines. The industry’s project pipeline was emptied, rushed to approval and built by the end of 2012.

During the cash grant program period, about 30,000 megawatts of new wind turbine capacity was built, more than doubling U.S. wind turbine capacity. The U.S. had never experienced that rate of growth with just the production tax credit (PTC).

With domestic, abundant, low-CO2 emitting (compared with coal), no-particulate emitting, low-cost natural gas , and continued flat demand for electricity, it’s no surprise the cash-grant-induced wind turbine bubble collapsed and will likely push installations back to mid-2000s levels, or less, if the PTC is finally allowed to expire after 24 years.

If extended, the PTC, set to expire at the end of 2013, will offset above-market wholesale prices for wind energy, but will drive just moderate levels of wind turbine capacity growth.

Comments or Threats: Wind in Vermont

Turbine 9, Lowell Mountain
From Ver Mont's albums
Senate Bill 30 mandates Act 250 oversight for wind projects. It has strong bi-partisan support in the Vermont legislature.  (I blogged about this yesterday.)

 In the past two days, letters on both sides of this issue were referenced in the Valley News, my local paper.  The contrast in tone between the two letters is astonishing.  Read for yourself.

Urging Heightened Oversight for Wind

Eric Rosenbloom, a resident of Hartland, is opposed to wind development.  In his recent letter to the editor (Why Fear Act 250 Wind Review?) he explains it is not worth destroying our ridges for the small amount of energy that we can obtain from wind.  Quotes from his letter:

These projects, especially on otherwise fiercely protected ridgelines, are not green. The environmental (not to mention financial) costs far outweigh the necessarily minuscule benefit from a diffuse, intermittent and highly variable source...

If industrial-scale wind (and solar) are indeed beneficial to the environment and communities, locally as well as globally, then its marketers have nothing to fear from a more democratic and environmentally rigorous permitting process. If they do indeed have reason to fear, that’s precisely why we need to say yes to S.30.

If You Vote For Act 250 Oversight of Wind, I Will Do My Best to Destroy Your Political Career

In contrast, Jeff Wolfe wrote a recent letter against SB30.

Some background:

  • John Campbell is Vermont Senator from my town of Hartford.  He is a moderate Democrat, and President Pro Tempore of the Senate.  He has announced that he will vote for SB 30.
  • Jeff Wolfe, president of Gro-Solar from White River Junction (also in my town of Hartford), wrote a letter to Senator Campbell, and he posted it on Vermont Digger.   

Some quotes from the Wolfe letter, as posted on the Digger website:

I was astonished to hear that you personally support S.30....This anti renewable energy effort is well documented as being funded by the Koch brothers and their allies. I’m truly surprised and stunned that you are falling for their lies, deceit, fake science, and name-calling. As the ‘leader’ of the Vermont Senate, I expect more from you.

John, I’ve supported you for a lot of races. But if you support this bill, not only does that support end, but I will help recruit and support opposition to you in the next election, and will put my money where my mouth is. 

 John Gregg, political analyst in the Valley News reported Campbell's reaction to Wolfe's letter.  Gregg's column is Tower Power.

Campbell... said Wolfe “has publicly threatened me and tried to intimidate me to vote one way, and I think it would send a bad message” were he to change his vote.

“For him to have associated me with the Koch brothers, I find it a bit ironic,” Campbell said, referring to the industrialists who have funded numerous conservative causes, some linked to the Tea Party movement. “The Koch brothers, what they are known for is their bullying tactics, intimidation and threats ... that’s pretty much the activity (Wolfe) is engaged in.”

Compare and Contrast:

Now that you have done the reading, here's the quiz:

  • Which letter makes a reasoned argument?
  • Which letter uses personal attacks ("Koch brothers") and future threats ("I will help recruit and support opposition to you..")?
  • Which letter is "green"? 
  • Which letter-writer holds the moral high ground? 
  • Which letter-writer thinks he holds the moral high ground?
  • Who gets to decide Vermont land-use?


Update:  Today's Valley News Editorial  against Wolfe letter to Campbell

Hardball in Vermont: Environmental Fight Turns Nasty

Two quotes from the editorial:

The first paragraph includes: Jeff Wolfe delivered an unmistakable message to state Sen. John Campbell of Hartford that the game being played is hardball — or maybe moneyball.

Later in the editorial: Indeed we haven’t seen yet a convincing case that large-scale wind energy can play a significant role in reducing carbon emissions in Vermont, which would be the only rational basis for sacrificing a landscape that plays such an important role in the state’s economy and self-identity.

Actually, They Did Fix the Cooling Towers. Or, the importance of confronting falsehoods

My blog post It Was Safety Safety Safety. Lawyers can't rescue a weak case was originally published as an op-ed in my local paper, the Valley News, on February 10.  (It may be behind a paywall at this point.)  In the paper, it was illustrated by a picture similar to this one:



After  one of my op-ed pieces appears in the Valley News, I get myself emotionally ready for the replies in the letters to the editor section.   I usually handle this sort of thing pretty well.  After all, the negative comments are not really about me.  It's all about nuclear power...

The First Letter Blows My Cool

Whoops. Actually, I don't always handle it that well.  As I proved by reading the first letter that appeared, about four days after my op-ed ran.

Before we get to that first letter and what happened afterwards, let's look at that picture again. That first  letter didn't discuss my article, it discussed the picture: A Telling Picture of Vermont Yankee.  Here's the first substantive statement in that letter:

"You can tell it’s an old photo because both banks of cooling towers are working. One has since collapsed (in 2007) due to lack of maintenance and has never been repaired."

I read this and hit the roof.   What-What-What!  He claims that the cooling towers had never been repaired!  Broken since 2007! What an outright...outright...outright.....

A cooling tower is repaired or not-repaired.  It's not an ambiguous situation.   Of course the cooling towers were repaired since 2007!

I called the editor of the paper and asked him to run a correction.  Before doing so, he wanted more than my word that the cooling towers had been repaired.  He wanted the date when the cooling tower repair was completed.

This date for the completion of the repairs wasn't mentioned in any article I could find, though I did find an article that implied that repairs were complete in spring 2008.   I contacted the plant and obtained the repair-completion-date information that the editor needed. The plant sent me an email from one of the engineers, and they gave me permission to forward the email to the editor.  That took care of the matter from my end.  The Valley News editor,  Martin Frank, wrote a correction.

 Here's the correction that now appears  on the Valley News website at the end of the "Telling Picture of Vermont Yankee" letter.

CORRECTION

The following correction appeared in the Feb. 28 edition of the Valley News:

The cooling tower at the Vermont Yankee nuclear power plant that collapsed in 2007 was permanently repaired and back in service by May 2008. A letter published Feb. 14 incorrectly asserted that the structure had never been repaired.

Whew!  And a big thank you to editor Martin Frank for his professional handling of the situation.

Howard's Letter

This was not the only letter about my post, but it was the most difficult to deal with.  Happily, Howard Shaffer wrote a great letter refuting several negative letters. His letter, The Facts About Vermont Yankee discusses the the tower repairs, the economic requirements for owning a nuclear plant, and more. Here is one of my favorite paragraphs from Shaffer's letter:

"The third letter claims tritium is dangerous. So is arsenic in our drinking water — or not, depending on the amount. Drinking water is needed for life, but can kill you — as was proven by the tragic case of the marathon runner who drank too much. (Meredith's) op-ed never said that tritium in any amount was not dangerous, just that the tritium-tainted water that leaked from Vermont Yankee was not. “The dose makes the poison” is true of radiation, too."

Was It Worth It?


Decision Tree
from Wikipedia
All's well that ends well? Since Martin Frank wrote a correction and Howard Shaffer wrote a letter, is the problem solved? In other words, was it worth the time it took to get this correction made?

Maybe yes and maybe no.

The letters claimed all sorts of things about the dangers of the spent fuel pool, the dangers of tritium, thermal discharge into the Connecticut River etc.  (Only one letter even mentioned the economic contribution of the plant to the area, which was the gist of my op-ed.)

Yet the only thing that we countered was that the cooling towers were actually repaired.  Did that matter?

I think it did.  Most of the statements in the opponent letters are non-falsifiable. They are more matters of opinion or faith than of science.  They provide nothing to test or to verify, though there may be something to argue about.

However, when nuclear opponents begin using incorrect facts, something has to be done about it.  You have to get a correction in print.  You really have to do so if you possibly can.  At least, that's how I feel about it.

------------

Extra Credit Reading: About Some Other Letters


One letter was the usual thing: Safety and economics are linked.  It included the odd statement that: "Is it possible that the law regarding regulation of nuclear power was designed to present the illusion of their (safety and economic) separability in an attempt to eliminate the possibility of legal challenge by states and local communities?"

Well, that's one way of looking at federal-level  safety regulations, I guess. My main response to this letter was "ho-hum, same-old."

Another letter was somewhat more annoying.  Titled Misinformation on Vermont Yankee,  it starts with "Defenders of Entergy’s attempts to continue operation of the controversial Vermont Yankee nuclear power plant in Vernon are waging a strategic war of misinformation..."It goes on to talk about the dangers of tritium. The letter finished by explaining that the letter-writer had read the "small print" at the end of the op-ed. He discovered that:  I worked for the nuclear industry in the past,  I blog as "yes vermont yankee," and I am associated with the Ethan Allen Institute.  

Gosh, I didn't think the type at the end of the op-ed was that small!  Should I ask the editor to put that information in a bigger font next time?   

Basically, once again, however, my response was "ho--hum."  Though I admit I don't like to be accused of  "waging a strategic war of misinformation."

At any rate, the accusation that I am waging a "strategic war of misinformation" is sort of....non-falsifiable.

Column: Lawyers Can’t Rescue a Weak Case | Valley News

Column: Lawyers Can’t Rescue a Weak Case | Valley News

My op-ed in the Valley News this morning. In appeals court, Vermont lawyers tried to make the case that Vermont has "economic" reasons to shut Vermont Yankee.

Actually, of course, Vermont Yankee is a major economic asset to the state of Vermont. Vermont has no economic reason to close it.

As the title says: "Lawyers can't rescue a weak case."

The Price of Power in the Northeast

I wrote an op-ed for the Valley News (my local paper) on price of power in the Northeast.  Nuclear plants are providing the backstop against electricity price rises due to the rising price of natural gas.  I am proud that my op-ed is on the front page of the Valley News Perspective section. Vermont's Surplus of Power Uncertainty

The paper came late to my doorstep today.  Before it had even arrived, I had an email from a member of my town selectboard thanking me for the informative article.  That sort of thing just makes me glow!

A hearty thank you to Martin Frank, editor of the Valley News.  He helped me achieve clarity as well as brevity on this subject.  That is what a good editor can do.  I am grateful.

Let me also encourage you to read the 135th Carnival of Nuclear Bloggers, now posted at ANS Nuclear Cafe.  As usual, the best of the nuclear blog scene, and all in one place for easy reading.

The Vermont Renewable Scene: It's Awkward (for me)

On Saturday, December 1, the Vermont Energy and Climate Action Network (VECAN) held its annual conference at the Lake Morey Resort. The theme of the conference was meeting Vermont's Comprehensive Energy Plan goals of 90% renewables for all energy uses by 2050.  If you remember, the Comprehensive Energy Plant was pushed through by the Shumlin administration in 2011. I blogged about the plan extensively, for example, in the post Hurry Up. Hurry Up.  Renewables. Don't Pay Attention to the Gas Pipeline.

Talking to the Press

The day before the VECAN meeting about the renewables goal, John Gregg of the Valley News emailed me to ask if I would be willing to comment on whether the 90% goal was reasonable.  He emailed that Jon Wolper was attending the conference and writing the article.  I emailed back that of course I would be willing to comment. I have a great deal of respect for John Gregg, and I was very happy to be asked.

Actually, I didn't just say: "Yes, I'll comment." I wrote a long email to Gregg and Wolper about renewables.

The day after the meeting, on Sunday, the Jon Wolper article appeared in the Valley News: Vermont Energy Advocates at Fairlee Conference Eye 90 Percent by 2050 Goal.   It includes a quote from my email. I think it is an excellent article.

The article starts:

Fairlee — For a group of about 300 energy officials and advocates brainstorming how to accomplish a certain state plan yesterday, adjectives reigned.
They said that Vermont’s Comprehensive Energy Plan, which is meant to get the state to 90 percent renewable energy usage by 2050, was bold. It was huge. Audacious. Ambitious. Extraordinary.
Also, essential.

The article ends with the following quote from me:

“No, it is not possible by 2050,” wrote Meredith Angwin, a physical chemist, in an email. ....
“It may never be possible," she said.

I think the Valley News article was clear-eyed about the challenges.

Talking to the Ethan Allen Institute

When I'm quoted in the press, I usually send a link to various people at the Ethan Allen Institute. The Institute is the parent organization for my Energy Education Project.  Rob Roper, the new president of the Institute, emailed me after he received the link to the Valley News article.  Roper said he thought that I had probably said more than "not possible...may never be possible."  Did I give my reasons for "not possible" in the email I sent the reporters?

I assured him I had sent quite a lengthy email to the Valley News, with reasons and links and everything. I sent him a copy of the email.

In Roper's opinion, the incomplete quote in the article was used to portray me as a "negative Nellie." Roper has written a letter to the editor about my quote.

Talking to my Blog Readers

At this point, I will close the blog post with an edited version of the email that I sent to the Valley News.
  • In terms of the Valley News, I know that reporters have space constraints, and I don't feel I was quoted badly.  
  • In terms of the Ethan Allen Institute, I understand Roper's point.  
So it is up to you, dear readers, to tell me what you think of the quote and the email.

Here it is:
***********

Hello Jon and John

Thank you for asking me for my opinion!

About 90% renewable energy...your substantive question...no, it is not possible by 2050.  It may never BE possible, unless our "behavior modification" includes dropping our population to far less than it is now.  You see, renewable energy is pretty land-intensive, and we just can't devote that sort of land area to it and keep any type of society as we have it now.
--------
Note: the original meeting announcement said this about the keynote speaker:

 Dr. Martenson will speak to why he believes a 90 percent renewable energy goal is now a necessity. 
"Getting to 90 percent renewable by 2050 is critical. To get there, however, will require major behavior modification by governments, corporations and individuals.."
-----------
I encourage you to look at this free book on the web...Sustainable Energy Without the Hot Air

http://www.withouthotair.com/

You can download the book, or the synopsis, for free. My son-in-law, a professor of mechanical engineering at Columbia, uses this book as one of the texts for his first-level energy course.  MacKay is a professor at Cambridge and  scientific advisor to UK on climate change.  I am not recommending some off-the-wall book here.

http://en.wikipedia.org/wiki/David_J._C._MacKay

Closer to home, you might want to interview Dr. Robert Hargraves, who has a recent self-published book on a type of new reactors (thorium reactors) which has gotten wonderful reviews by Nobel-prize winners.  Hargraves lives in Hanover.

Hargraves recently spoke in China to a very good reception by some very important people
http://energyfromthorium.com/2012/11/04/lftr-leader-jiang-mianheng-addresses-itheo/

And he gave a recent seminar at Dartmouth
http://www.youtube.com/watch?v=SS2JrWa_Wkc

Here's his book
http://www.amazon.com/THORIUM-energy-cheaper-than-coal/dp/1478161299

The important thing, from your point of view, is that the first half of the Hargraves book expands on MacKay's book.  If renewables can supply what we need in the future, then we don't need thorium or any nuclear source, or really, any energy-dense source at all (coal, etc.)  Except that...renewables can't do it for a modern society. Worth reading the book or watching the first part of the Dartmouth talk.

Well, this is long enough!  I just hope it is helpful!

Best,
Meredith

Trojan Cows and Grid Facts: Op-Ed

Non-Trojan Cow
The Cow

On July 1, a group of people opposed to the continued operation of Vermont Yankee protested at the nuclear power plant’s gates. One prop they used to dramatize their belief that there are better energy options than nuclear power was a hollow “Trojan Cow” they pulled to the demonstration. Some protesters pulled mock solar panels out of the cow, while others held whirligigs representing wind turbines. The cow sculpture even included a representation of manure, representing “cow power” energy produced from farm methane. The theme was clear: Vermont Yankee will be replaced with renewables.

Well, that is simply not true, at least in the foreseeable future. Closing Vermont Yankee will not bring a burst of renewables to market to replace its power.

Grid Power

Closing Vermont Yankee would mean buying more power from the New England grid to make up for Vermont Yankee’s supply. Grid power is approximately 58 percent fossil fuel, 28 percent nuclear and 12 percent hydro plus renewables. Wind, solar and farm methane together account for less than 1 percent of the power generated in New England.

What would closing Vermont Yankee mean? More solar power on the grid? No. With or without Vermont Yankee, renewables are expensive, and they are not coming on line quickly.

On the other hand, fossil fuel plants are abundant suppliers to the New England grid, supplying the majority of grid power. Many fossil fuel plants operate only part-time. The part-time plants run when they are needed to satisfy the power requirements on hot summer days or cold winter evenings. They also operate when nuclear plants are down for refueling.
The New England Grid responds to nuclear refueling
From Vermont Dept Public Service  presentation

If Vermont Yankee closed, existing fossil fuel plants would compensate by running longer hours and making more power. If the Vermont Yankee protesters had wanted to stage a more accurate dramatization, they would have pulled a model of a gas or coal plant from their Trojan Cow’s belly, not a cardboard solar panel.

Renewables: Too Slow, and Too Expensive

Or perhaps the demonstrators were claiming that shutting down nuclear plants will bring more rapid development of renewable energy, even if we’re forced to use more fossil fuels for a “short while.”

Well, a “short while” is likely to be very long.

For example, the Vermont state energy plan calls for the state to meet 90 percent of its total energy needs from renewable sources by 2050. That’s an ambitious goal considering that Vermont does not meet its current renewable energy goals and has no prospects of meeting them in the near future. The Vermont energy plan established a goal of having the state use 20 percent of its electricity from renewable sources by 2017. Even using optimistic assumptions about project completion, the state will attain only the 16 percent mark in by that date. In 2009, the state had 13 percent of its electricity from renewables (mostly in-state hydro). A growth of 3 percentage points over eight years ( 13 to 16%, 2009 to 2017) is not very impressive.

Perhaps the rate of growth of renewables is accelerating? Not really. Last year, the Vermont Legislature voted against having an aggressive Renewable Portfolio Standard for Vermont. Such a standard might raise the percentage of renewables in Vermont, but it would also raise Vermont electricity rates to unacceptable levels. Renewable growth is slow in neighboring states for similar reasons. In short, closing Vermont Yankee would have the regional result of requiring more fossil fuel to supply the New England grid.

Vermont Is An Island?

Within Vermont, many anti-nuclear activists don’t seem to care much about the regional issue. They often say that the power from Vermont Yankee doesn’t matter to Vermont, because “Vermont is no longer using any Vermont Yankee power.”

Not true. In March of this year, the power contracts between Vermont utilities and Vermont Yankee ended. Vermont utilities no longer buy Vermont Yankee power. However people in Vermont are still using Vermont Yankee power.

That sounds weird, but realize that buying power and using power are different, because power from different sources blends together on the grid. The supply on the grid depends on the power plants, transmission lines and end-users. These don’t change when contracts change.

Buying and Paying

Who pays for the power is a different matter altogether: Payment depends on agreements made between plants and utilities and regulators. The day after Vermont Yankee stopped selling power to Vermont utilities, Vermont consumers used the same actual power mix as they had used the day before. However, on that day, Vermont consumers began paying for power in a different manner. Among other changes, Vermont consumers began paying for Seabrook power, according to a contract between Green Mountain Power and Seabrook. This did not mean that Seabrook power suddenly began streaming into local power lines.

Once again, we have to take into account the regional nature of the grid. Power contracts determine payment methods, but contracts don’t determine power routing and use — that is determined by plant availability and geography.

Power blends together on the grid. If a plant goes off-line, other plants take up the slack. When nuclear plants go off-line, fossil fuel plants step up and produce replacement power.

(Note: Howard Shaffer wrote an excellent description of the grid at his recent guest post: Where's the Magic Switch?)

Deception 

Protesters used a Trojan Cow to suggest that if Vermont Yankee closed, renewables would take its place. Perhaps the use of a Trojan animal was more apt than the demonstrators intended. After all, the original Trojan horse was designed to deceive. In this case, the people that the demonstrators are deceiving about the consequences of closing Vermont Yankee start with...themselves.

-----
This is a slightly edited version of an op-ed I wrote for my local paper, the Valley  News.  I wrote this op-ed about the July 1 "Trojan Cow" protest at Vermont Yankee. It appeared in the Valley News on Sunday, July 29, but the Valley News puts very little of its content on-line.   I felt this op-ed fit in well with Howard Shaffer's recent blog post about the grid: Where's the Magic Switch.

You can watch a three-minute video of the demonstration on YouTube.
