In an attempt to protect existing customers from higher costs due to the expansion of the electric grid to serve new large-load electric customers, including hyperscale data centers, the Pennsylvania Public Utility Commission published a Tentative Order in the Pennsylvania Bulletin proposing a statewide model tariff to guide how large electric customers connect to the grid and share costs responsibly. Public comment is now being accepted on the tentative order through December 22, 2025.

 The tentative order reflects input gathered by the commission through a hearing in April 2025 and includes input from utilities, industry, consumer advocates, and the public. The order encourages large-load customers to contribute toward programs to help low-income customers; encourages faster, more transparent interconnections; and incentivizes flexibility by providing rate options for large-load customers willing to accept interruptible or flexible service during peak demand.   

  Proposed tariffs would only address distribution costs and would not address electric generation costs that will continue to increase based on rising demand. The PUC does not have regulatory oversight of electric generation, as generation is not regulated in Pennsylvania. Click here for the Tentative Order.
