HARRISBURG, PA — As Pennsylvania faces a rapid rise in electricity demand driven by large-scale data center development, House lawmakers have approved House Bill 1834, a measure that begins to establish a policy framework for managing the sector’s impacts on the state’s grid, consumers and environment. The bill now moves to the Senate for consideration.

Data centers, which can consume as much electricity as entire towns, are expected to significantly increase energy demand across the PJM Interconnection region. The passage of HB 1834 reflects growing recognition in Harrisburg that this growth requires clear rules and oversight, according to the Sierra Club Pennsylvania Chapter, part of America’s oldest and largest grassroots environmental organization.

“Pennsylvania is entering a new phase of electricity demand growth, and this legislation is an important step toward planning for that reality,” said Tom Schuster, Director of the Sierra Club Pennsylvania Chapter. “HB 1834 begins to set standards for how these very large energy users connect to the grid, who pays for the infrastructure they require and how their impacts are managed.”

The legislation establishes several new requirements for large load users, including:

• A requirement that data centers procure an increasing share of their electricity from new, in-state clean energy resources — starting at 10% in 2027 and rising to 32% by 2035
• Financial contributions to support energy affordability programs, including enhanced funding for the Low-Income Home Energy Assistance Program (LIHEAP)
• Direction to regulators to ensure that the costs of serving large data centers are not shifted onto residential customers and small businesses
• Operational requirements intended to reduce strain on the electric grid and limit air pollution from high-emitting backup generation during system emergencies

These provisions represent meaningful progress in a policy area where no significant guardrails previously existed, according to the Sierra Club PA Chapter.

“At a time when electricity demand is projected to increase with unprecedented speed, it is critical to ensure that new large loads do not compromise reliability or drive up costs for existing customers,” Schuster said. “We call on the Senate to act quickly to adopt these important safeguards.”

“HB 1834 establishes a foundation, but it does not yet match the scale or speed of the issue,” Schuster added. “Additional policy work will be needed to ensure that data center growth does not lead to higher electricity bills, increased pollution, or avoidable strain on the grid.”
