PUC Adopts Proposed Model Tariff for Large Load Customers
On April 30, 2026 the Pennsylvania Public Utility Commission (PUC) advanced a proposed model tariff for large load customers – including rapidly expanding data centers – voting 5-0 to adopt a motion from Chairman Steve DeFrank modifying a draft final order under consideration at today’s public meeting.
The Commission’s action reflects continued efforts to establish a clear, consistent framework for managing significant new electricity demand while protecting existing ratepayers and maintaining grid reliability.
The model tariff follows an extensive Commission review, including an en banc hearing, multiple rounds of public comments, and input from a broad range of stakeholders representing utilities, large load customers, consumer advocates, policymakers, and community organizations. Because the Commission adopted a motion modifying the draft final order, a revised final order incorporating those changes will be issued in the coming days.
“This is an unprecedented time for our electrical grid – one that presents both significant challenges and important opportunities,” said PUC Chairman Steve DeFrank. “Data centers and advanced manufacturing are driving a level of load growth that we have not seen in generations. This action represents an important step toward establishing clear rules that support economic development while ensuring that existing customers are protected from unnecessary costs.”
A copy of the order in Docket Docket No.: M-2025-3054271 was not available at the time of publication.
