Pennsylvania lawmaker drafts bill requiring data centers to pay grid costs

Pennsylvania Data Center Grid Costs are the focus of draft legislation requiring large-load projects to fund generation, transmission and distribution upgrades, support emergency curtailment, and protect electricity customers from infrastructure expenses.

Pennsylvania lawmakers are preparing legislation that would require data centers to bear the electric-system costs associated with their demand, including new generation, transmission, distribution and other grid infrastructure. The proposal, being drafted by the chair of the state House energy committee, would put recent state actions affecting data-center development into statute. The measure centers on the principle that costs created by large new loads should not be shifted to existing electricity customers, an issue also reflected in Pennsylvania power rates discussions across the state.

Under the draft framework, a data center that requires additional power plants, transmission lines, distribution equipment or related grid work would be responsible for those costs. The approach would apply the cost-causation principle directly to facilities with substantial electricity requirements. That focus places the proposal alongside broader concerns about Transmission upgrade delays pjm network queues, where the timing and funding of network work can affect large-load connections.

The legislation would also require electric utilities to use the state Public Utility Commission's large-load tariff for customers that include data centers. That tariff assigns infrastructure and connection costs to large customers, requires deposits and collateral for financial security, and calls for interconnection studies to be completed within six months. The tariff currently is voluntary. Making it mandatory would establish a more uniform utility process for projects seeking high-capacity service. Similar questions about assigning connection expenses are raised by Data centre transmission cost policy canada, a subject relevant to large-load planning.

Another major element would require data centers to reduce electricity use during grid emergencies. Facilities would have to meet that curtailment obligation unless they have sufficient on-site generation to operate without relying on the grid during those conditions. The provision follows an executive order directing the commission to develop protocols that would interrupt service to data centers before other consumers when the system is under stress. The proposed emergency requirement highlights the operational challenges examined in Canadian data center impact coverage of rapidly growing computing loads.

The bill would reinforce state GRID standards for data-center development, including the expectation that facilities bring their own power supply. A House measure containing those standards passed in June, but the Senate has not acted on it. An analyst has said the bring-your-own-power requirement will require legislation, coordination with the regional grid operator and expanded commission authority to be effective. The draft arrives as policymakers weigh infrastructure needs across generation and grid development, including issues connected to Utilities solar tilt and other supply decisions.
