Using information provided by utilities, the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) has developed Top 10 rankings of utility green power programs for 2012.

Under these voluntary programs, residential and commercial consumers can choose to help support additional electricity production from renewable resources, such as wind and solar.

Ranked by renewable energy sales (MWh/year), the top utilities are as follows:

1. Portland General Electric - 834,125 MWh/year
2. Austin Energy - 744,443 MWh/year
3. PacifiCorp - 604,007 MWh/year
4. Sacramento Municipal Utility District - 416,477 MWh/year
5. Xcel Energy - 390,056 MWh/year
6. Puget Sound Energy - 365,796 MWh/year
7. Connecticut Light and Power Co. / United Illuminating - 254,838 MWh/year
8. Dominion Virginia Power - 250,364 MWh/year
9. Oklahoma Gas & Electric Co. - 210,187 MWh/year
10. CPS Energy - 179,786 MWh/year

Portland General Electric overtook Austin Energy in 2012, selling the largest amount of renewable energy in the nation through its voluntary green power program. Dominion Virginia Power and Oklahoma Gas & Electric are new to the top renewable energy sales list.

According to the report, green power sales of the top 10 utility programs exceeded 4.2 million MWh in 2012, up from 3.9 million MWh in 2010, and wind energy represents approximately 85% of electricity generated for green energy programs nationwide.

Ranked by the percentage of customer participation, the top utilities as follows:

1. City of Palo Alto (California) - 18.2%
2. Portland General Electric - 12.4%
3. Madison Gas & Electric Co. - 9.4%
4. Sacramento Municipal Utility District - 9.2%
5. City of Naperville (Illinois) - 7.6%
6. Pacific Power (Oregon) - 7.6%
7. Silicon Valley Power - 6.9%
8. River Falls Municipal Utilities - 6.1%
9. Stoughton Utilities - 5.1%
10. Cuba City Light & Water - 5.0%

“Participating in utility green power programs allows consumers to support renewable energy above and beyond what utilities are procuring to comply with state renewable portfolio standards,” says NREL Analyst Jenny Heeter. “These utilities are offering first-rate programs that give their customers an opportunity to support renewable energy deployment.”
