Voluntary Green Power Procurement

NREL has tracked the voluntary green power market since its inception in the 1990s to help corporate purchasers, utilities, and others selling renewable energy products understand available renewable options and move renewable energy forward.

Voluntary green power is separate from renewables used to meet state renewable portfolio standards. View visualizations of NREL's voluntary green power market data over time. View U.S. voluntary green power market data for 2021.

Renewable Energy Procurement Options by Utility

NREL has developed a comprehensive list of renewable energy procurement options available by utility and municipality nationwide. NREL has also developed a separate list of active utility green pricing programs with more detailed information on these programs. To NREL’s knowledge, these lists identify all active procurement options or green pricing programs nationwide. We welcome your input; if you see that a program is missing or inaccurate, please contact Jenny Heeter.
