The Pew Charitable Trusts, in partnership with the North Carolina Clean Energy Technology Center, developed the Distributed Energy Resources State Policy Explorer to compile and share DER-related legislation enacted throughout the country from 2021 through 2025. The policies in the explorer showcase the range of approaches available to expand the use of DERs through improved grid planning, community resilience, and addressing barriers to permitting and interconnection—the process for connecting energy generators and batteries to the grid.

The state policy explorer features an interactive U.S. map. It contains more than 400 entries, allowing users to filter results by state; policy area (e.g., building codes, community solar, and investment support); crosscutting topics (e.g., resilience); technology, including energy storage, photovoltaic solar, electric vehicles and charging infrastructure; and demand response.

(According to the National Association of State Energy Officials,
PACE—which most commonly stands for “property assessed clean energy”—“enables
property owners to implement energy improvements on their property and repay
the costs over an assigned term (typically between 15 and 20
years) through an assessment on their property tax bill.”)
