RE: RE: RE: InflationNo, the PPA absolutely can not be renegotiated once it goes into effect. There are penalties and lawsuits that would put the company out of business. It's a serious contract. Even not meeting minimum performance standards (not producing enough MW for instance) would produce penalties.

Carbon credits have been dead for a few years but I could see some version of them re-appearing if the world economy recovers enough. A voluntary, locally-driven carbon trading scheme might work--a European utility buying credits for a few million a year from Ram at San Jacinto to meet a portion of their local renewable performance standards. There's social pressure for carbon-producing companies to make some kind of gesture of saving the planet, even if there isn't a global accord.
