Rate Schedules & Tariff Analysis

Mon Power C&I bills are dominated by demand charges that grow with customer size and primary-voltage service. Energy charges decline as customers move up schedules (from ~$0.114/kWh on small Schedule B to ~$0.045/kWh on Schedule K), while demand charges and customer charges rise. Schedule C and D are billed on kW demand; Schedule K is billed on kVA, rewarding good power factor. All figures are effective January 1, 2026 per WV PSC Case No. 25-0772-E-ENEC; a separate base-rate increase is pending for 2026-2027.

Monongahela Power Rate Schedule List

ScheduleApplicability
Schedule B - General Service<=10 kW; energy-only with minimum demand floor
Schedule C - General ServiceDemand-metered; $17.04/kW demand
Schedule D - GS PrimaryPrimary voltage; tiered demand $18.20/$16.48 per kW
Schedule K - Large PowerLarge/transmission; kVA-based demand $14.111

Monongahela Power Rate Features & TOU Details

  • Energy charge falls and demand/customer charges rise as customers move from Schedule B to K
  • Schedule K bills demand on kVA, so power-factor correction directly reduces cost
  • Voltage discounts ($0.25/kW) apply above 2,000 V (Schedule C) and 15,000 V (Schedule D)
  • Minimum bills tied to historical or contracted demand (e.g., $4.60/kW on Schedule C)
  • Multiple surcharges apply (environmental control, vegetation management, renewable, ENEC)

Monongahela Power Data Access FAQ

How can a CSP or aggregator get bulk billing and interval data for Mon Power customers?▾

Register as a Curtailment/Conservation Service Provider with FirstEnergy to receive secure FTP credentials, then submit a signed customer Letter of Authorization (LOA) plus a data-request form via FTP. Billing, usage, and interval files (fixed-width text or CSV) are returned within 1-2 business days. Note that new standard LOA forms are required after November 1, 2025.

Does Mon Power support EDI for usage and billing data?▾

Yes. FirstEnergy supports NAESB ANSI X12 EDI (v4010) including 810 (invoice), 814/814 HU (enrollment and historical usage request), 820 (payment), and 867/867 HU/867 IU (monthly, historical, and interval usage). Enroll through Supplier Services at 330-761-4348, complete EDI testing, and connect via NAESB direct or a VAN.

Can a commercial customer get 15-minute interval data?▾

Yes. Smart-meter accounts can obtain 15-minute, 30-minute, or hourly interval data by requesting interval metering/pulse service, installing a HAN device for real-time data, or having an authorized CSP submit an 867 IU interval request. Standard portal access shows monthly data only.

Is there customer choice for electric supply in West Virginia?▾

No. West Virginia has not adopted retail customer choice, so commercial and industrial customers take bundled service from Mon Power under WV PSC-approved tariffs. EDI access is therefore used by curtailment/conservation providers and authorized data partners rather than competitive retail suppliers.

Which rate schedule applies to a commercial or industrial site?▾

Mon Power C&I service is tiered by size: Schedule B General Service (small, <=10 kW), Schedule C General Service (with demand metering), Schedule D General Service Primary (larger primary-voltage loads), and Schedule K Large Power (large/transmission-level industrial). Confirm the best fit with Mon Power at 800-686-0022.
