Rate Schedules & Tariff Analysis
TCEMC C&I pricing follows TVA's GSA structure: a minimum bill, per-kW demand charges above 50 kW (GSA-2/3), and declining-block energy pricing that rewards high-volume usage. Because rates track TVA's monthly wholesale cost, the energy charge changes each month; demand management and load factor are the main levers members control.

| GSA-1 (Small General Power) | Demand 0-50 kW and usage under 15,000 kWh. |
| GSA-2 (Medium General Power) | Demand 51-1,000 kW or usage over 15,000 kWh. |

Tri-County Electric Membership Corporation (TN) Data Access FAQ
Can a consultant pull a TCEMC commercial member's usage data through an API?▾
No. TCEMC has no public API, Green Button Connect, or Share My Data program. All third-party access is manual and customer-authorized: submit a signed authorization to Member Services (mwoodard@tcemc.org) and expect PDF/email delivery in 10-20 business days, possibly with a copying fee.
What interval granularity can a C&I member get?▾
The portal shows daily/monthly kWh only. AMI meters are interval-capable and 15-minute data is used for demand response, but granular interval reads must be requested manually from Member Services (10-20 business days) and may carry a fee.
Which rate schedule applies to a commercial or industrial facility?▾
TCEMC uses TVA's General Power Schedule GSA, split by demand: GSA-1 (0-50 kW, <15,000 kWh), GSA-2 (51-1,000 kW or >15,000 kWh), and GSA-3 (>1,000 kW). GSA-2 and GSA-3 add per-kW demand charges with declining-block energy pricing.
Why do TCEMC commercial rates change every month?▾
TCEMC is a TVA distributor, so retail rates fluctuate monthly with TVA's wholesale cost of power. The cooperative publishes the current month's GSA charges on its Commercial Rates page; the values shown here are for June 2026.
Is TCEMC rate-regulated by a state public utility commission?▾
No. As a member-owned cooperative in Tennessee/Kentucky, TCEMC is not regulated by a state PUC. Wholesale power and rate structure are governed by its TVA power contract, and the board sets local rate adders.
