by Jbs050610 e3 — May 12, 2010—The U.S. Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL) has released its annual assessment of leading utility green power programs. Under these voluntary programs, consumers can choose to help support additional electricity production from renewable resources such as wind and solar.
According to the NREL analysis, more than 850 utilities across the United States now offer green power programs. Utility green power sales in 2009 exceeded 6 billion kilowatt-hours (kWh), and they represent more than five percent of total electricity sales for some of the most popular programs. Wind energy represents approximately two-thirds of electricity generated for green energy programs nationwide.
Using information provided by utilities, NREL developed “Top 10” rankings of utility programs for 2009 in the following categories: total sales of renewable energy to program participants, total number of customer participants, the percentage of customer participation, green power sales as a percentage of total utility retail electricity sales, and the lowest price premium charged for a green power program using new renewable resources.
Ranked by renewable energy sales (kWh/year), Austin Energy in Austin, Texas sold the largest amount of renewable energy in the nation through its voluntary green power program. Rounding out the top five are Portland General Electric (OR), PacifiCorp (OR and five other states), the Sacramento Municipal Utility District (CA), and Xcel Energy (CO, MN, WI and NM).
Ranked by the percentage of customer participation, the top utilities are City of Palo Alto Utilities (CA), Portland General Electric, Madison Gas and Electric Company (WI), the Sacramento Municipal Utility District (CA), and the City of Naperville (IL).
