Rate Schedules & Tariff Analysis

For C&I customers, the dominant cost drivers under SWEPCO's GS, LGS, and Large Power schedules are the demand charge ($/kW billing demand) and the fuel/fixed-fuel factor, more than the base energy charge. Because SWEPCO Texas is regulated SPP (no ERCOT shopping), there is no competitive supply rate to compare; optimization centers on selecting the correct schedule, managing peak demand, and tracking rider changes. The temporary Turk Remand Credit Rider currently reduces Texas bills.

Southwestern Electric Power Company (SWEPCO) Rate Schedule List

ScheduleApplicability
General Service (GS)Small/mid commercial
Large General Service (LGS)Larger commercial / light industrial, demand-metered
Large Power / IndustrialLarge industrial at primary/transmission voltage
ES-LL (proposed)New loads >= 75 MW

Southwestern Electric Power Company (SWEPCO) Rate Features & TOU Details

  • Bundled, regulated rates (no retail supplier choice)
  • Demand charges ($/kW) drive C&I bills
  • Fuel / fixed-fuel factor rider adjusts energy cost
  • Turk Remand Credit Rider reduces TX bills through ~early 2027

Southwestern Electric Power Company (SWEPCO) Data Access FAQ

Can SWEPCO C&I customers in Texas choose a competitive electricity supplier?

No. SWEPCO's Texas territory is in regulated Southwest Power Pool (SPP) territory, not the competitive ERCOT market. C&I customers buy bundled service from SWEPCO at PUCT-approved rates and cannot shop for a retail electric provider as ERCOT-area customers can.

How does a business get interval (15-minute) data for energy analysis?

On accounts with AMI smart meters, download a Green Button (ESPI XML) file from the Energy Usage dashboard, or authorize a third party through Green Button Connect My Data via UtilityAPI to pull meter, bill, and 15-minute interval data through the API.

What drives a SWEPCO commercial bill the most?

For demand-metered C&I schedules (LGS, Large Power), the billing demand charge ($/kW) and the fuel/fixed-fuel factor are usually the largest components, often outweighing the base energy charge. Managing peak demand has the biggest impact.

What is the Turk Remand Credit Rider on Texas bills?

It is a temporary bill credit returning about $147.5 million to Texas customers over 24 months beginning February 2025, following a PUCT-approved settlement over Turk Power Plant construction financing costs. Credit amounts vary with usage.

Is there a special rate for very large new loads like data centers?

SWEPCO filed a proposed Electric Service - Large Load (ES-LL) standard contract with the PUCT in October 2025 (Control No. 58796) that would generally apply to new customers with contract capacity of 75 MW or more. Terms are pending Commission approval.
