Wholesale market should support asks that specify carbon content, bids that offer premium for low carbon #275

I believe this is the essence of "green" power, right? Perhaps there could be other attributes that could be specified in asks and for which bids might offer a premium, but one example will be enough to start with.

The way this is typically handled in the real world (at present) is that buyers enter into long-term contracts with low-carbon providers and bypass the day-ahead market. Is there a way to model this in Power TAC?

What about leveraging product type and having two parallel markets for green and black energy. Your weighted position in the two + contracted generation is your realized carbon content? This would have the nice side effect of realizing a second clearing price on green energy?

Product type is a blunt instrument for this purpose, I think. For example, if I'm interested in minimizing carbon content, I would expect to pay more for power produced from natural gas than from coal, but even more for wind.

There is very new idea at EPEX which envisions a two-stage auction for marketing green energy. First auction is power, second auction is green energy bonus. I think evaluating such a mechanism would be a terrific idea for PowerTAC 2012.
