It's minus 24 at my house this morning, and here are some pix I snapped of the ISO-NE Real-Time system page.
To me, the first one is the most telling: 20,000 MW demand, 243 MW in reserve. That's too little reserve!
The rest are more typical winter ISO.
Grid running at over $200/MWh.
Actually, it has been bouncing up to over $300/MWh, in the five-minute market. I just didn't get a screen shot at the higher levels.
And here's the fuel mix: Lots of coal and oil, of course: total of 27%. Renewables hanging in at 6%.
And the renewables chart. Wind is actually a reasonable part of it, since this has been windy weather. Wood and refuse dominate, of course. Of course, what is "reasonable"? Wind is 17% of 6% on a day the grid is struggling.
