Delivery charges are tiered by customer class and demand level, and the published $ values live in the filed retail tariff. The strategic levers for C&I customers are (1) shopping competitive supply against the SOS benchmark and (2) managing billed demand (kW).

Limitations & Considerations

- ⚠Online billing history is limited to roughly 24 months; older records require a manual request.
- ⚠Zigbee pulse service and interval-meter work orders carry hardware and installation fees.
- ⚠Specific commercial/industrial $ rate values are not published in summary form and must be read from the filed tariff book.
The Potomac Edison Company Data Access FAQ
How does a commercial customer in Maryland get interval (smart meter) data from Potomac Edison?▾
Hourly usage is viewable in the Analyze Usage section of My Account. For machine-readable interval data, large C&I customers and their authorized consultants use EDI 814/867 transactions or the SU-MR third-party portal with a signed Letter of Authorization. Real-time interval data is available via Zigbee pulse service for an installation fee.
Can an energy consultant pull our usage data on our behalf?▾
Yes. The consultant registers with FirstEnergy's third-party data access program (or Maryland Supplier Services), submits a signed Letter of Authorization, and then retrieves data through the SU-MR portal or via EDI. Individual-account access requires the LOA; aggregated/anonymous data sets can be requested without one.
Does Potomac Edison support Green Button?▾
Green Button Download My Data and Connect My Data are not explicitly documented for Potomac Edison. FirstEnergy relies on NAESB EDI (ANSI X12) for automated third-party data exchange. C&I customers needing standardized exports should plan around EDI or the SU-MR portal and confirm any ESPI-format options with Supplier Services.
We're a large C&I site in Maryland — do we have to buy supply from Potomac Edison?▾
No. Maryland is a deregulated retail-choice market. You can stay on Potomac Edison's default Standard Offer Service or contract generation supply from any licensed competitive retail electricity supplier. Potomac Edison still provides regulated delivery and consolidated billing in either case.
Is West Virginia service different?▾
Yes. West Virginia is a fully regulated market with no retail choice; Potomac Edison is the bundled default provider. Data-access mechanisms (portal, EDI, pulse service) are similar, but there is no competitive supplier shopping.
