The Regional Greenhouse Gas Initiative is an effort by nine states to constrain carbon dioxide emissions from the electric power sector using a cap-and-trade program. This paper assesses the importance of long-term electricity contracts under the program. We find that 12.2% of generation will be accounted for by long-term contracts in 2010, affecting select nuclear, hydroelectric, and cogeneration units. The contracts will have a negligible effect on the wholesale marginal cost of electricity and a small effect on retail price. States may want to consider contracts on a case-by-case basis when making decisions about the initial distribution of emission allowances, but they should account for effects on the portfolio of plants owned at the firm level, not... |
