Pennsylvania State Solar Overview
Pennsylvania’s solar market remains relatively underdeveloped compared to neighboring states, but growing policy and industry momentum is building across all market segments. Key legislative priorities include HB2348, which would reform net metering by replacing avoided cost with a new grid value rate and expanding residential system sizes, and HB2264, which would establish virtual power plant programs. HB2429, which would require utilities to publish distribution system hosting capacity maps, is another important step toward improving grid transparency for solar development. On the regulatory front, key proceedings on interconnection and DER wholesale market participation are advancing, with major comment deadlines approaching this summer.

Pennsylvania Energy Storage Policy and Market Overview
Energy storage deployment in Pennsylvania is in the early stages of development.
While there is growing interest in expanding storage, policy and regulatory uncertainty, particularly around ownership models and procurement structures, continues to slow market growth. The Public Utility Commission has taken a case-by-case approach, and the lack of standardized frameworks and incentives has limited large-scale deployment.
Despite these challenges, Pennsylvania’s broader energy market shows potential for growth, with increasing solar deployment and investment activity. Continued policy development and clearer market signals will be critical to unlocking a more competitive and scalable energy storage market in the state.
