NREL Announces Its 2014 Utility Green Power Leaders

Utility Green Power Leader Portland General Electric
Renewable energy projects in Oregon - the nation's green utility leader.

The Department of Energy’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 2014 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 1.1 million megawatt-hours (MWh) of renewable energy through its voluntary green power program. Dominion Virginia Power was new to the top renewable energy sales list in the 8th spot. Green power sales of the top 10 utility programs exceeded 4.68 million MWh in 2014, up from 4.54 million MWh in 2013.

Ranked by the percentage of customer participation, the top utility was Portland General Electric’s Green Source program (12.33%), followed by Sacramento Municipal Utility District (2nd-11.76%) and Wellesley Municipal Light Plant (3rd-11.05%). Eversource/United Illuminating was new to the top participation rate list with 8.93% (5th), ranking after the Farmers Electric Cooperative of Kalona (10.46%-4th). In addition, ranked by number of customer participants, Portland General Electric and PacifiCorp both exceed 100,000 customers participating in green power programs during 2014.
