Is the $846 billion that electricity producers would pay for the right to emit greenhouse gasses part of the opportunity cost of producing electricity?

Representatives Waxman of California and Markey of Massachusetts proposed a law to limit greenhouse gas emissions from electricity generation and require electricity producers to generate a minimum percentage of power using renewable fuels, with some emission rights to be auctioned. The Congressional Budget Office estimated that the government would receive $846 billion from auctions and would spend $821 billion on incentive programs and compensation for higher energy prices. Electricity producers would spend $208 million a year to comply with the new rules. (Think of these dollar amounts as dollars’ worth of other goods and services.)
