Pennsylvania's Statewide Large Load Tariff Framework: What It Means for AI Data Center Siting in Pennsylvania

September 18, 2026 6 min read Strategic Crypto Reserve Data Center Infrastructure

50 MW individually or 100 MW in aggregate triggers Pennsylvania's modified Large Load Tariff Framework, adopted by the Public Utility Commission in April 2026 to set clear statewide rules for high-demand customers as electricity needs surge, on top of a large-load tariff already included in PPL Electric Utilities' rate-review settlement.

Pennsylvania at a glance: industrial power about 8.8¢/kWh (EIA-based, indexed to April 2026) · grid queue about 36 months · data center equipment tax exemption: available. Indicative figures from the SCR AI Build Configurator v1.4.0.

Frequently Asked Questions

What is Pennsylvania's Statewide Large Load Tariff Framework?

50 MW individually or 100 MW in aggregate triggers Pennsylvania's modified Large Load Tariff Framework, adopted by the Public Utility Commission in April 2026 to set clear statewide rules for high-demand customers as electricity needs surge, on top of a large-load tariff already included in PPL Electric Utilities' rate-review settlement.

Why did Pennsylvania PUC (applies across PPL, PECO and other member utilities) introduce this large-load structure?

To ensure the cost of new generation, transmission and distribution infrastructure built to serve very large customers, chiefly hyperscale data centers, is paid for by those customers rather than spread across the general rate base of residential and small commercial ratepayers.

What large data center projects are already active in Pennsylvania?

PPL is serving a 1,350 MW, three-campus data center complex in Carlisle and a 1,200 MW Nebius project in Butler Township backed by a Dedicated Energy Services Agreement shielding ratepayers from cost exposure; PECO is planning for a $20 billion pipeline of AWS data centers statewide.

Does this tariff replace Pennsylvania's standard commercial and industrial rates?

No. Pennsylvania's Statewide Large Load Tariff Framework sits above Pennsylvania PUC (applies across PPL, PECO and other member utilities)'s standard commercial and industrial rate schedules and applies specifically to customers that meet or exceed the large-load threshold described above. Smaller commercial and industrial loads continue to be billed under existing rate schedules.

How can I model a Pennsylvania data center build against this tariff and other states?

The SCR AI Build Configurator applies Pennsylvania's power cost, tax treatment and large-load tariff rules alongside all other US states and Canadian provinces, so a Pennsylvania scenario can be compared line-by-line against any alternative site.
