Current Rate Schedules
MTEMC's commercial and industrial customers are served under the General Power (GSA) schedule for loads under 5,000 kW, tiered by demand. The figures below are verified from MTEMC's official Rate Schedule effective June 2026. Energy charges combine a base rate plus the monthly TVA Fuel Cost Adjustment (FCA), shown here at the June 2026 FCA of $0.02733/kWh (GSA) and $0.02704/kWh (GSA3/4). Loads above 5,000 kW are quoted by Key Accounts.

Rate Recommendations by Use Case
Mid-size commercial facility (51-1,000 kW)
Most retail, office and light-industrial sites in MTEMC territory fall on GSA2, where demand charges above 50 kW become significant.
GSA2 has a low per-kWh energy rate but a $15.38/kW demand charge above 50 kW, so controlling peak demand is the dominant cost lever.
- Pull 15-minute Green Button data to map your demand peaks
- Stagger equipment startups to avoid coincident peaks
- Consider the Comprehensive Services Program for a load study
Large industrial plant (1,001-5,000 kW)
Large manufacturers and data-center-scale loads fall on GSA3 or GSA4 with contract demand.
Energy rates drop to ~$0.057/kWh base, but demand ($14.40-$14.45/kW) and contract-demand provisions make demand management and accurate contract sizing critical.
- Right-size contract demand to avoid penalties above the higher of 2,500 kW or contract demand
- Use interval data for continuous demand monitoring
- Engage Key Accounts for loads approaching 5,000 kW
EV fast-charging operator
Public DC fast-charging sites between 50 kW and 5,000 kW use the dedicated EVC schedule.
EVC avoids standard demand charges with a flat ~$0.245/kWh all-in energy rate, which suits intermittent high-power charging loads.
- Confirm station demand exceeds 50 kW to qualify
- Model utilization to compare EVC versus GSA economics
- Track monthly TVA FCA impact on per-kWh cost
Historical Rate Trends
MTEMC's base rates are set by its board within the TVA wholesale framework. Month-to-month bill variation is driven almost entirely by the TVA Fuel Cost Adjustment rather than base-rate changes. Comparing MTEMC's published schedules, the May 2026 to June 2026 update shifted demand and energy charges modestly upward.
June 1, 2026
June 2026 rate schedule: GSA2 demand rose to $15.38/kW (from $14.28/kW in May), GSA3/4 demand to $14.45/$14.40 (from $13.37/$13.33), reflecting updated base rates and TVA FCA.
+7.7%Overall trend: Base rates relatively stable; monthly variation dominated by the TVA FCA.
Next expected change: FCA updates monthly per TVA; next base rate review at the board's discretion.
Cost Optimization Strategies
For MTEMC commercial and industrial members, the largest savings opportunities come from managing peak demand (kW) and shifting load off peak, since demand charges dominate bills above 50 kW. Interval data via Green Button is the key input for these strategies.
Peak demand management
For: GSA2, GSA3, GSA4 accounts above 50 kW
Use 15-minute Green Button interval data to identify and shave demand peaks, lowering the billed kW that drives $14.40-$15.38/kW demand charges on GSA2-GSA4.
Time-of-use load shifting
For: Commercial/industrial accounts with flexible load
Enroll in MTEMC's Key Accounts time-of-use rate and shift discretionary load off peak periods.
Right-size rate schedule
For: All non-residential accounts
Confirm the account is on the most economical GSA tier for its demand and consumption profile, since fixed and demand charges differ markedly between GSA1-GSA4.

Frequently Asked Questions
Can my business get 15-minute interval data from MTEMC?▾
Yes. All AMI-metered accounts can download up to 14 months of 15-minute interval data in Green Button XML format from the My Usage section of myMTE. Raw CSV export is not a standard service, but the XML can be converted, or you can request a custom export through Member Services or Key Accounts.
Does MTEMC support automated third-party data access?▾
Yes, through Green Button Connect My Data on the SmartHub platform. A customer authorizes a third-party application via OAuth 2.0, and the app can then retrieve interval data automatically without the customer sharing credentials. There is no public developer portal; register through Business Services.
Which rate applies to my commercial or industrial facility?▾
MTEMC's General Power (GSA) schedule applies to most non-residential accounts under 5,000 kW. GSA1 covers small accounts (0-50 kW and under 15,000 kWh), GSA2 covers 51-1,000 kW or over 15,000 kWh, and GSA3/GSA4 cover larger contract-demand accounts (1,001-2,500 kW and 2,501-5,000 kW). Loads above 5,000 kW are handled by Key Accounts.
Why does my MTEMC bill change month to month?▾
MTEMC passes through the TVA Fuel Cost Adjustment (FCA), which varies monthly based on TVA's forecasted fuel and purchased-power costs. The FCA is added to the base energy rate, and every penny collected goes directly to TVA. MTEMC has no control over the FCA.
Can I shop for a different electricity supplier?▾
No. Tennessee does not have retail electric choice. As a TVA distributor, MTEMC is the sole electricity provider in its territory, so there is no competitive supplier market or shopping portal.
