Report Names Top Utilities With “Green Pricing” Programs

Published On

Each year since 2000, the National Renewable Energy Laboratory (NREL), Golden, Colo., has compiled and reported data on electric utilities that offer “green pricing” programs to their customers. These programs allow homes and businesses to procure green power directly from their electric utilities.

The types of power available for green pricing programs include wind, solar, biomass and small hydro. The NREL identifies three types of green pricing programs: energy-based (by far the most common), contribution programs and capacity-based programs.

Energy-based programs allow customers to choose a discrete amount of energy to be supplied from renewable sources, either in 100-kilowatt-hour (kWh) “blocks” or as a fixed percentage of their monthly electric energy requirements. In fact, many utilities with energy-based programs allow customers to obtain 100% of their electricity use from green power sources.

Contribution programs allow customers to contribute to a utility-managed fund for renewable energy project development. Most of these programs are designed to help fund green power for community locations, such as schools.

Capacity-based programs offer their customers fixed blocks of electricity capacity generated from renewable energy sources.

The NREL has just released its report for 2019, which lists the top ten utilities in four categories: total green power sales, total green power customers, green power sales rates and green power participation rates.
