Market Overview
Monongahela Power, a FirstEnergy operating company, is a regulated monopoly under the West Virginia Public Service Commission. All service is bundled and billed under WV PSC-approved tariffs. West Virginia has not implemented retail customer choice, so there is no competitive supplier market; EDI/CSP access serves curtailment, conservation, and data-aggregation partners.

Rate Recommendations by Use Case
Small commercial site (<=10 kW)
Small retail, office, or service businesses below the demand-metering threshold.
Schedule B is energy-only with a low $10 customer charge and a modest demand floor, fitting small loads under 10 kW.
- Watch usage approaching 10 kW, which triggers reclassification
- Use the Analyze Usage tool to track monthly consumption
- Enroll in eBill for timely notifications
Mid-size commercial facility (demand-metered)
Offices, retail centers, and light industrial with demand metering on Schedule C.
Schedule C trades a lower energy charge ($0.05557/kWh) for a $17.04/kW demand charge, so peak management drives savings.
- Shave coincident peaks to cut the $17.04/kW demand charge
- Capture the $0.25/kW voltage discount if served above 2,000 V
- Pull interval data to find demand drivers
Large facility on primary voltage
Larger campuses and manufacturers taking primary-voltage service on Schedule D.
Schedule D offers lower energy ($0.05146/kWh) and a voltage discount above 15,000 V, with tiered demand charges that reward scale.
- Evaluate primary-voltage service for the $0.25/kW discount
- Manage the first-500-kW demand block at $18.20/kW
- Use demand response and storage to trim peaks
Large industrial / transmission load
Energy-intensive industrials and transmission-level loads on Schedule K.
Schedule K has the lowest energy charge ($0.04510/kWh) but bills demand on kVA, so power factor and load factor are decisive.
- Install capacitor banks to correct power factor and lower billed kVA
- Maximize load factor to dilute the $14.111/kVA demand charge
- Use CSP/EDI interval data for granular demand analysis
Energy consultant / aggregator
Advisors and aggregators needing programmatic access to many customers' data.
Mon Power offers genuine machine-readable access via CSP/FTP, NAESB EDI, and the StS HIU platform — stronger than most peer utilities.
- Register as a CSP for FTP file access (1-2 business day turnaround)
- Enroll in EDI for automated 867 usage/interval data
- Use updated standard LOA forms required after Nov 1, 2025
Historical Rate Trends
Mon Power rates change through periodic WV PSC base-rate cases and the annual Expanded Net Energy Cost (ENEC) proceeding that trues up fuel and purchased-power costs.
January 1, 2026
Current tariff rate sheets (Schedules A-K) effective January 1, 2026 under WV PSC Case No. 25-0772-E-ENEC (annual ENEC true-up of fuel and purchased-power costs).
n/aAugust 1, 2026
Proposed Mon Power/Potomac Edison base-rate increase (~$188.4M) pending before the WV PSC; one option raises residential ~13.9%, commercial ~8%, industrial ~7.8%, with a first step proposed effective Aug 1, 2026.
+8% (commercial, proposed)Overall trend: Upward — driven by ENEC fuel/purchased-power recovery and proposed base-rate increases
Next expected change: Pending base-rate case proposing a ~$188.4M increase with a first step proposed effective August 1, 2026 and a second step June 1, 2027 (evidentiary hearing July 9, 2026)
Cost Optimization Strategies
Mon Power C&I savings come from managing demand, optimizing power factor (especially on kVA-billed Schedule K), and selecting the correct schedule and service voltage.
Peak demand management
For: Schedules C, D, and K
Reduce the maximum on-peak demand that sets monthly demand charges by staggering loads and shifting flexible operations off peak.
Power-factor correction
For: Schedule K (kVA-billed) large industrial customers
Because Schedule K bills demand on kVA, improving power factor with capacitors directly lowers billed demand.
Voltage and schedule selection
For: Customers near schedule/voltage thresholds
Taking service at higher voltage captures voltage discounts ($0.25/kW above 2,000 V on C or 15,000 V on D); confirm the lowest-cost eligible schedule.
Interval data analytics
For: Smart-meter C&I customers
Request interval metering or HAN data to identify demand drivers and target curtailment; consultants can pull interval data via CSP/EDI.
To implement these strategies, you need your 15-minute interval data. Learn how to download Monongahela Power interval data →
Frequently Asked Questions
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.
