Why It Matters
Pennsylvania households and businesses are contending with higher electricity costs just as state legislators debate whether a sweeping battery storage requirement could bring long-term relief to the grid. The convergence of rate increases and an active legislative proposal has elevated the urgency of the discussion in Harrisburg.
What Happened
The Pennsylvania House Energy Committee, led by chairwoman Rep. Elizabeth Fiedler, convened a hearing on a proposal to compel the state’s major electric utilities to dramatically expand their battery storage capacity. House Bill 2380, sponsored by Rep. Nikki Rivera (D-Lancaster), sets a target of 3,000 megawatts of installed battery storage statewide by 2033.
Chris D’Agnostino, who serves as head of state policy for Advanced Energy United, appeared before the panel to make the case for the bill. “Battery storage is no longer an emerging technology. It’s a proven grid resource that can help address some of Pennsylvania’s most pressing energy challenges,” D’Agnostino told the committee. Grid-scale storage systems collect power generated by wind, solar, hydroelectric, and thermal sources and dispatch it back onto the grid when consumption peaks — a mechanism that can moderate price volatility and guard against supply gaps.
The industry group representing existing utilities took a more skeptical stance. Andy Tubbs, president and CEO of the Energy Association of Pennsylvania, questioned the basis for the bill’s specific requirements. “The acquisition targets would be more understandable if we had better footing … where these targets are stemming from,” Tubbs said during his testimony. Michelle Buczkowski, CEO of EOS Energy Enterprises, also testified, representing battery storage manufacturers.
By the Numbers
- 28th: Pennsylvania’s current national ranking in installed battery storage capacity
- 3,000 megawatts: total storage requirement under H.B. 2380, to be met by 2033
- 2,000 megawatts of that total would be short-duration storage (systems capable of discharging for up to four hours); the remaining 1,000 megawatts would be long-duration storage (minimum 10-hour discharge capacity)
- 600,000 customers: the service-load threshold above which a utility would be subject to the mandate
- 1.5% to nearly 20%: range of rate increases now in effect for customers of 11 electricity distribution companies across the state
Under the bill’s framework, the Pennsylvania Public Utility Commission — chaired by Stephen DeFrank — would divide the storage obligations among qualifying utilities based on each company’s service territory size and annual peak demand figures.
Several utilities have taken preliminary steps toward storage deployment. PPL currently runs two battery storage facilities, and Duquesne Light completed a two-year pilot program. UGI Electric received approval for its own pilot but ultimately did not move forward, citing cost obstacles.
Zoom Out
Pennsylvania’s electricity market operates within PJM Interconnection, a regional transmission organization that coordinates power supply across 13 states and Washington, D.C. Tensions between the state and PJM over wholesale pricing came to a head when Gov. Josh Shapiro’s office filed suit against the organization in late 2024. The two parties reached a settlement that included an extended price ceiling — an arrangement that has provided temporary relief but left underlying structural questions unresolved.
The drive to mandate battery storage capacity follows a pattern visible in multiple states as power grids absorb growing shares of intermittent renewable generation. Policymakers in states from California to the mid-Atlantic region have begun treating large-scale storage as an essential reliability tool rather than an optional supplement. Pennsylvania’s middle-tier ranking nationally suggests it has room to expand, though the pace and method of that expansion remain points of contention.
What’s Next
H.B. 2380 remains in the House Energy Committee following the hearing. Lawmakers will evaluate the competing testimony before deciding whether to advance the bill for a full chamber vote. If the measure becomes law, utilities would have until 2033 to fulfill their assigned storage shares, with the PUC responsible for monitoring compliance. The outcome carries consequences for both electricity reliability and consumer costs across one of the nation’s most populous states.
