Most utilities also have Power Purchase Agreements (PPAs) for a great deal of electricity at a lower price. But utilities would not purchase enough electricity with PPAs to fill all these peaks. <br /><br />So, this is the price above a previously contracted price...but basically, the utility would have a contract for a contracted price with a single provider, and expect to buy more power, as needed, from the grid. <br /><br />This is how the "grid" price is running.<br /><br />But wait, there's more! It's even more complicated! Green Mountain Power made a PPA with HydroQuebec, but the price of that power moves with the market price! So some PPAs are also affected by this price.Meredith Angwinhttps://www.blogger.com/profile/02737538041807740424noreply@blogger.comtag:blogger.com,1999:blog-3033288879708780106.post-22569583265042945372014-01-24T10:14:15.563-05:002014-01-24T10:14:15.563-05:00Does every producer get this higher price or is th...Does every producer get this higher price or is this just the price of "extra" production?
