Market Overview
Mountaineer Gas is a fully regulated natural gas distribution utility under the West Virginia Public Service Commission. There is no retail gas commodity choice; all C&I customers take bundled service under WV PSC-approved tariff schedules, with the purchased gas adjustment (PGA) set in PSC proceedings.

Current Rate Schedules
Mountaineer Gas C&I rates are fully regulated by the WV PSC and published as tariff schedules. Commercial and industrial customers take service under General Service (GS), Large General Service (LGS / LGS-I), Industrial Service (IS), Large Industrial Service (LIS), or General Transportation Service (GTS). Each bundled bill combines a fixed monthly customer charge, a volumetric delivery charge per Mcf, and a Purchased Gas Adjustment (PGA) commodity pass-through. As of 2026 the PGA commodity rates by class were approximately $7.391/Mcf for GS and $3.960/Mcf for LGS and IS. On February 3, 2026 the company filed a base rate case (Case No. 26-0003-G-42T) seeking about $26.8M in additional annual revenue (~8.44% average increase across ~218,000 customers); the WV PSC suspended the rates, so any change takes effect no earlier than December 1, 2026. Exact current per-unit delivery charges are in the schedule PDFs linked below.

Rate Recommendations by Use Case
Higher-volume commercial account reducing total gas cost
Compare GS against LGS/LGS-I. In 2026 the PGA commodity rate alone is far lower on LGS (~$3.96/Mcf) than GS (~$7.39/Mcf), so qualifying for LGS can cut cost sharply above the volume breakpoint.
The verified 2026 PGA gap between GS and LGS makes schedule selection the highest-leverage lever for commercial accounts.
- Pull 12 months of Mcf from bills to test the LGS qualification threshold
- Compare the customer charge increase against the per-Mcf and PGA savings
- Re-check schedules after Case 26-0003-G-42T concludes (rates no earlier than Dec 1, 2026)
Large industrial facility minimizing delivered gas cost
Evaluate Large Industrial Service vs. General Transportation Service. GTS plus a negotiated supply contract can beat the bundled PGA for steady high-volume loads.
Highest-volume schedules offer the lowest per-Mcf delivery, and self-supply via GTS replaces the bundled commodity with a market contract.
- Model annual Mcf against LIS and GTS thresholds in the schedule PDFs
- Solicit competitive gas supply bids for a GTS arrangement
- Confirm telemetering/balancing obligations under GTS
Energy consultant/aggregator onboarding Mountaineer Gas C&I accounts
Plan for fully manual data acquisition. With no API, Green Button, or EDI, build a written-authorization workflow and request billing/usage history by phone, budgeting for fees.
Mountaineer Gas has no third-party authorization portal; data comes only via manual, fee-based requests or shared doxo access.
- Collect signed written authorizations from each client
- Submit formal data requests to 1-800-834-2070 and allow 5-10 business days
- Use published tariff PDFs to model costs since per-unit data is otherwise PDF-only
Historical Rate Trends
Mountaineer Gas delivery rates are reset through WV PSC base rate cases; the PGA commodity component adjusts periodically. The IREP (Infrastructure Replacement and Expansion Program) surcharge also affects bills.
February 3, 2026
Base rate case filed (Case No. 26-0003-G-42T) seeking ~$26.8M additional annual revenue (~8.44% average increase); residential bills proposed to rise ~10.57%, small commercial ~4.09%. WV PSC suspended rates pending review.
+8.44% (proposed average)Overall trend: Upward pressure from infrastructure investment, with a large 2026 base rate case pending PSC review.
Next expected change: Base rate case 26-0003-G-42T — proposed rates no earlier than December 1, 2026, pending WV PSC decision.
Cost Optimization Strategies
With no commodity choice and regulated delivery rates, Mountaineer Gas C&I cost optimization centers on selecting the right tariff schedule, evaluating transportation, and reducing consumption.
Right-size the rate schedule
For: Higher-volume C&I
Higher-volume accounts may qualify for LGS, IS, or LIS, which trade a higher fixed charge for lower per-Mcf delivery and (notably) a lower PGA commodity rate than GS — a material saving above the volume breakpoint.
Evaluate transportation (GTS)
For: Large industrial
Large users can take General Transportation Service and arrange their own gas supply, paying Mountaineer Gas for delivery only — potentially beating the bundled PGA with a negotiated supply contract.
Reduce consumption
For: All C&I
Because delivery and commodity are both volumetric per Mcf, efficiency and weatherization directly cut the variable portion of the bill.
Engage in the rate case
For: Large C&I
Intervene or comment in WV PSC Case 26-0003-G-42T to influence proposed C&I rate design before new rates take effect.

Frequently Asked Questions
Can a C&I customer or consultant access Mountaineer Gas usage data via API or Green Button?▾
No. Mountaineer Gas has no Green Button (Download or Connect My Data), no ESPI implementation, and no public API. Commercial usage is available only as monthly Mcf on bills via the online/doxo portal, or through a manual, fee-based data request authorized in writing by the customer.
What interval granularity is available for commercial gas accounts?▾
None. Mountaineer Gas reads meters monthly, so the finest granularity is the monthly billing total in Mcf. No 15-minute, hourly, or daily interval gas data is available; AMI deployment is not publicly documented. Certain large transportation customers may have telemetering under the GTS schedule, but this is not a customer data-access program.
How does a third party obtain a commercial customer's data?▾
There is no authorization portal. The customer provides written authorization naming the third party and the data requested, then the third party submits a formal request to Business Services (1-800-834-2070). Mountaineer Gas may charge a reasonable fee and typically responds in 5-10 business days with PDF/printed data.
Which rate schedule applies to a commercial or industrial gas account?▾
Mountaineer Gas publishes General Service (GS) for typical commercial accounts, Large General Service (LGS and LGS-I) for higher-volume customers, Industrial Service (IS) and Large Industrial Service (LIS) for industrial loads, and General Transportation Service (GTS) for customers arranging delivery-only service. Each schedule's PDF is on the Rates and Tariffs (Business) page.
Is a rate change coming for commercial and industrial customers?▾
Yes. On February 3, 2026, Mountaineer Gas filed a base rate case (Case No. 26-0003-G-42T) seeking about $26.8M in additional annual revenue (roughly an 8.44% overall average increase). The WV PSC suspended the proposed rates, so any new rates would take effect no earlier than December 1, 2026, pending review.
