This is the overall statewide trend behind the individual utility price to compare increases: the average Pennsylvania household's total electric bill grew by roughly a fifth between 2024 and 2026.

The Pennsylvania Public Utility Commission approved a statewide model tariff framework in April 2026 that tells electric utilities how to handle very large new customers such as data centers, generally those wanting 50 megawatts or more at one site or 75 to 100 megawatts across nearby sites. It requires these customers to pay the cost of any grid upgrades their connection requires, commit to minimum contract terms, and put up financial security, rather than spreading those costs across all ratepayers. Individual utilities, including PPL Electric and Duquesne Light, are now folding versions of this large load tariff into their own rate filings.
What it means for your bill: This does not change anyone's electric rate directly, but it is meant to stop the cost of new substations and power lines built for data centers from being added to everyone else's bill.

Other Statewide matters
The order is meant to keep new data centers from pushing their power costs onto residential electric bills by requiring developers to pay for all of their own electricity.
