Rate Schedules & Tariff Analysis
Piedmont's C&I rate design separates a fixed monthly facilities charge from a per-therm commodity/delivery charge, with seasonal differentials (higher winter rates Nov-Mar). The most consequential lever for large customers is choosing between bundled firm sales (Rates 102/152) and transportation service (Rates 113/213/214), where the customer procures its own gas supply and pays Piedmont a delivery/demand charge plus balancing.
Piedmont Natural Gas Rate Schedule List
| Schedule | Applicability |
|---|---|
| Rate 102 - Small General Service | Small commercial firm sales (NC) |
| Rate 152 - Medium General Service | Medium commercial firm sales (NC) |
| Rate 113 - Large General Transportation | Large transportation customers (NC) |
| Rates 213-214 - Transportation | Industrial/large commercial transportation |
Piedmont Natural Gas Rate Features & TOU Details
- Fixed facilities charge plus seasonal per-therm commodity/delivery charge
- Winter rates in effect November through March
- Transportation schedules let large customers buy their own gas supply
- Demand-style charges on large transportation service (e.g., Rate 113: $1.39435/therm)
