Market Overview
Kingsport Power is an investor-owned utility regulated by the Tennessee Public Utility Commission. Tennessee does not have retail electric choice, so there are no competitive suppliers, no CRES market, and no supplier-switching EDI.

Current Rate Schedules
Rates below are from the Kingsport Power Company T.P.U.C. Tariff No. 3, effective November 1, 2025. Base energy charges are low because fuel is recovered separately through the monthly Fuel and Purchased Power Adjustment Rider (FPPAR). C&I service charges, energy charges, and demand charges are verified from the filed tariff.
Effective: November 1, 2025 · Full Tariff Book →
| Schedule | Type | Applicability | Structure | Rate |
|---|---|---|---|---|
| Small General Service (SGS) | commercial | General service customers with normal maximum demand less than 10 kW. | Service charge plus tiered energy charge; no demand charge. | Service charge $22.03/mo; energy 3.225 cents/kWh first 600 kWh, 2.076 cents/kWh over 600 kWh (plus FPPAR fuel rider)+ None |
| Medium General Service (MGS) | commercial | General service customers with demand of 10 kW or greater (not available to new customers over 100 kW). | Service charge + energy charge on first 200 hours-use + demand charge per kW; secondary or primary voltage. | Secondary: service $69.28/mo, energy 3.438 cents/kWh; Primary: service $216.28/mo, energy 2.927 cents/kWh (plus FPPAR)+ $3.54/kW secondary; $3.49/kW primary |
| General Service Time-of-Day (GS-TOD) | commercial | General service customers with demand greater than 10 kW but less than 100 kW (limited to first 100 enrollees). | Service charge plus on-peak energy charge; off-peak energy billed at zero. On-peak is 6 a.m.-9 p.m. weekdays. | Service charge $72.23/mo; on-peak energy 4.422 cents/kWh, off-peak 0.000 cents/kWh (plus FPPAR)+ None (time-of-day energy pricing) |
| Large General Service (LGS) | commercial | General service customers with normal maximum demand greater than 100 kVA but less than 3,000 kVA. | Demand charge per kVA + energy charge per kWh + fixed service charge; secondary, primary, or subtransmission voltage. | Secondary: demand $8.99/kVA, energy 0.787 cents/kWh, service $208.78/mo; Primary: demand $7.98/kVA, energy 0.851 cents/kWh, service $441.64/mo (plus FPPAR)+ $8.99/kVA secondary; $7.98/kVA primary; $4.43/kVA subtransmission |
| Industrial Power (IP) | industrial | Industrial and large commercial customers contracting for at least 3,000 kW of capacity. | Demand charge per kW + off-peak excess demand charge + fixed service charge + reactive demand charge; energy recovered via FPPAR. | Secondary: demand $7.24/kW, service $391.46/mo; Primary: demand $5.61/kW, service $610.07/mo; reactive $0.75/kVAR over 50% of metered kW (plus FPPAR)+ $7.24/kW secondary; $5.61/kW primary; $3.06/kW subtransmission |
Rate Recommendations by Use Case
Mid-size commercial facility (10-100 kW)
Most retail, office, and light-commercial sites fall under Medium General Service, where a per-kW demand charge becomes a meaningful share of the bill.
MGS adds a $3.54/kW (secondary) demand charge, so reducing coincident peak demand directly lowers cost. Facilities that can shift load off-peak may save under GS-TOD, which bills off-peak energy at zero.
- Pull Green Button interval data to find your monthly 15-minute peak
- Stagger HVAC and large equipment startups to shave demand
- Evaluate GS-TOD if a large share of load can move to 9 p.m.-6 a.m.
Large commercial / multi-building campus (100-3,000 kVA)
Large General Service is demand-dominated and billed in kVA, so power factor and peak management matter as much as energy use.
LGS bills $8.99/kVA (secondary) or $7.98/kVA (primary) on a ratcheted minimum demand (60% of contract or prior-11-month peak). Taking service at primary voltage cuts the demand charge in exchange for a higher fixed charge.
- Correct power factor to reduce billed kVA
- Watch the demand ratchet — a single high peak sets a floor for 11 months
- Compare primary vs. secondary voltage service economics with your engineer
Industrial / manufacturing site (3,000 kW+)
Industrial Power is for contract-capacity customers and is almost entirely demand- and capacity-driven, with off-peak excess demand and reactive charges.
IP demand charges run $3.06-$7.24/kW by voltage with a 3,000 kW minimum and a 60% ratchet, plus a $0.75/kVAR reactive charge. Subtransmission/transmission service materially lowers the per-kW demand charge.
- Manage on-peak (6 a.m.-9 p.m.) demand to set a lower billing demand
- Keep power factor high to avoid the reactive demand charge
- Model subtransmission service if you can take power at higher voltage
Historical Rate Trends
Kingsport Power's retail rates are set by the TPUC, while the monthly FPPAR fuel rider passes through wholesale fuel and purchased-power costs and is updated periodically. A general rate case was litigated under TPUC Docket 21-00107.

Cost Optimization Strategies
Because Kingsport Power C&I bills are demand-driven and fuel costs pass through the FPPAR rider, the biggest savings levers for businesses are peak demand management, power factor correction, and voltage-level selection.
Peak demand management
For: MGS, LGS, IP
Use Green Button interval data to identify and flatten the monthly 15-minute peak that sets demand charges on MGS, LGS, and IP.
Power factor correction
For: LGS, IP
Add capacitors to keep power factor high and avoid the $0.75/kVAR reactive demand charge (IP) and reduce billed kVA on LGS.
Voltage-level / service selection
For: LGS, IP
Where feasible, take service at primary or subtransmission voltage to access lower per-kW/kVA demand charges.
Load shifting under GS-TOD
For: GS-TOD eligible (10-100 kW)
Facilities under 100 kW that can shift load to off-peak hours (9 p.m.-6 a.m.) may benefit from zero off-peak energy pricing on GS-TOD.
