Large-load customers under Maryland's 2025 Next Generation Energy Act and 2026 Utility RELIEF Act are the subject of separate proposals filed September 1, 2026 by Potomac Edison and Maryland's Exelon utilities for a specific rate schedule, directly implementing the two recent state laws aimed at ensuring large loads cover their own cost of service.
Also active in Maryland: Maryland's pipeline includes a 2,400 MW Quantum Frederick Project data centre in Frederick County served by Potomac Edison — one of the largest single proposed loads on the Mid-Atlantic grid.

Figures compiled from the Edison Electric Institute's "Large Load Projects and Tariffs" (September 2026) member-company summary and public regulatory filings. Confirm current tariff terms directly with Potomac Edison (FirstEnergy) and the Maryland Exelon companies and the relevant state public utility commission before relying on any figure for a capital decision.
Weighing Maryland against another state or a Canadian province with a different rate and interconnection picture entirely? Run both sides of the comparison through our licensed AI data centre cost configurator — it applies each jurisdiction's actual power rate, tax treatment and large-load tariff rules to the same seven build configurations.
Model This State on Your Own Site
Every figure above comes from the same power-cost and tariff dataset behind the SCR AI Build Configurator — a licensed, embeddable widget that models seven data centre build configurations against all nine Canadian provinces and all 50 US states plus DC, returning capital expenditure by line item, energy cost, revenue by commercial structure, EBITDA and payback.
| Licence | Price (CAD) | Who it suits |

| Enterprise | From $25,000 / year, up to 3 domains | Developers and EPC firms who want the model on their own cost basis with attribution removed |
