Pennsylvania Energy Storage Policy and Market Overview

The energy storage deployment is slow moving in Pennsylvania and faces an ambiguous future as stakeholders disagree on methods for stimulating the market.

A non-consensus among energy storage stakeholders in Pennsylvania concerning ownership models is undercutting market growth and system deployment. The PUC has taken neutral stances on ownership, with utilities opting for policies favoring easier procurement models. While industry actors favor a mixed method with options for competitive third-party ownership. The PUC actions indicate an energy storage awarding and ownership decision process that is on a case-by-case basis with no standardized distribution of procurement models.

The gubernatorial administration in Pennsylvania is supportive of renewable energy and storage technologies. Though, a lack of state-wide incentives, demonstration programs, and clearly regulated ownership models is stunting the competitive growth of the market.
