Several public power utilities are included on top 10 lists compiled by the National Renewable Energy Laboratory for utility green pricing programs. The recently released rankings are for 2018.

Using information provided by utilities, NREL has developed "Top 10" rankings of utility green pricing programs for 2018 in the following categories: total sales, total number of customer participants, and participation rate (the percentage of utility customers that participated in green pricing programs).
