June 2014 - The Energy Department's National Renewable Energy Laboratory (NREL) has released its assessment of leading utility green power programs. Using information provided by utilities, NREL has developed "Top 10" rankings of utility green power programs for 2013 in the following categories: total sales of renewable energy to program participants, total number of customer participants, the percentage of customer participation, and green power sales as a percentage of total utility retail electricity sales.
Ranked by renewable energy sales (megawatt-hours/year), Portland General Electric remained in the top spot by selling over a million megawatt-hours (MWh) of renewable energy through its voluntary green power program. Tennessee Valley Authority was new to the top renewable energy sales list in the 9th spot. Green power sales of the top 10 utility programs exceeded 4.6 million MWh in 2013, up from 4.2 million MWh in 2012.
Ranked by the percentage of customer participation, the top utility was City of Palo Alto Utilities (19.4%), followed by newcomers Farmers Electric Cooperative of Kalona (2nd-14%) and the Town of Wellesley Municipal Light Plant (4th-11.1%), with Portland General Electric (3rd-12.6%) and Sacramento Municipal Utility District (5th-10.4%) rounding out the top five spots.
