Until recently, both regulators and electric utilities have considered photovoltaic (PV) technology (i.e., solar cells) an unattractive

energy-supply option because of its relatively high cost. Now, however, a number of utilities have shown interest in using PV for peak-shaving.

Green Pricing: Removing the Guesswork

"Green pricing," at typical rates of customer participation, could expand demand for renewable energy beyond current levels by more than an order of magnitude, pushing down production costs for energy resources preferred by environmental advocates. And just as important, that expanded demand would occur outside of the regulatory framework (em matching capacity to customer needs and wants.In practice, the utility asks customers to pay rate premiums to fund the production or purchase of renewable resources.

EPA Awards Bonus SO2 Allowances

The Environmental Protection Agency (EPA) has awarded 1,349 acid rain bonus allowances to 10 utilities: City of Austin; New York State Electric and Gas; Orange and Rockland; Western Massachusetts Electric; United Illuminating; Cincinnati Gas and Electric; Massachusetts Electric; Granite State Electric; Narragansett Electric; and Long Island Lighting. The awards are based on utility energy efficiency and use of renewable energy.

Pursuant to the acid rain requirements of the 1990 Clean Air Act Amendments, an allowance licenses the emission of one ton of sulfur dioxide (SO2).
