Current Rate Schedules
Rates updated January 2026 under the FPSC's December 2024 approval, with the annual fuel charge reset to reflect 2025 actuals and 2026 projections. C&I customers take General Service Non-Demand (GS/GST), General Service Demand (GSD/GSDT), and General Service Large Demand (GSLD) schedules; demand schedules add a per-kW billing-demand charge. A temporary storm surcharge runs through August 2026. Verified figures below are TECO's published January 2026 rates; demand-schedule per-kW figures are described qualitatively where a current published value was not confirmed.
Effective: January 1, 2026 · Full Tariff Book →
| Schedule | Type | Applicability | Structure | Rate |
|---|---|---|---|---|
| General Service Non-Demand (GS) | commercial | Small commercial customers without demand metering. | Verified Jan 2026: Basic Service Charge 0.66¢/day; Energy Charge 9.202¢/kWh; Fuel Charge 3.516¢/kWh; Storm Protection 0.568¢/kWh; Clean Energy Transition 0.418¢/kWh; temporary Storm Surcharge 2.121¢/kWh (through Aug 2026). Energy charge includes 0.534¢/kWh of conservation/environmental/capacity cost-recovery. | — |
| Time-of-Day General Service Non-Demand (GST) | commercial | Small commercial customers electing time-of-day pricing without demand metering. | Verified Jan 2026: Basic Service Charge 0.66¢/day; Energy Charge 14.113¢/kWh on-peak / 7.514¢/kWh off-peak; Fuel Charge 3.822¢ on-peak / 3.376¢ off-peak; plus Storm Protection 0.568¢/kWh, Clean Energy Transition 0.418¢/kWh, and temporary Storm Surcharge 2.121¢/kWh. | — |
| General Service Demand (GSD / GSDT) | commercial | Medium commercial/industrial customers with demand metering (generally 25 kW and above). | Structure: monthly per-kW billing-demand charge plus an energy charge, fuel charge, storm protection, clean energy transition, and the temporary storm surcharge. A time-of-day variant (GSDT) layers on-peak/off-peak energy pricing. Exact per-kW demand figures should be confirmed in the current Retail Tariff Book; a recent TECO filing referenced a GSD demand charge on the order of ~$19/billing kW, but the current published value should be verified before quoting. | — |
| General Service Large Demand (GSLD) | industrial | Large commercial and industrial customers with substantial demand (large loads above the GSD tier). | Structure: per-kW billing-demand charge (with secondary/primary/transmission voltage differentials) plus energy, fuel, storm protection, clean energy transition, and temporary storm surcharge components. A time-of-day variant adds on-peak/off-peak energy pricing. Specific per-kW and per-kWh values are set in the FPSC-approved tariff sheets. | — |
| Interruptible / Standby Service (IS / SBI / SBF) | industrial | Very large industrial customers able to curtail load on TECO request, and customers with on-site generation needing standby/backup service. | Structure: discounted firm-equivalent demand/energy rates in exchange for interruptibility (IS), with standby and supplemental billing-demand provisions (SBI/SBF). Rates are governed by the tariff and are qualitatively described here; see the Retail Tariff Book for current values. | — |
Rate Recommendations by Use Case
Small commercial / single-site office or retail
Sites without significant demand peaks should compare GS against the time-of-day GST schedule and shift discretionary load off-peak.
GST's off-peak energy (7.514¢/kWh Jan 2026) is roughly half its on-peak rate, rewarding load shifting; sites with flat usage may prefer GS.
- Pull daily usage from Interactive Bill to see your load shape
- Run equipment off-peak where possible
- Enroll in paperless/EDI for cleaner records
Medium C&I with demand metering
Demand-metered facilities should take GSD/GSDT and aggressively manage peak kW, using interval data to find and shave peaks.
The per-kW billing-demand charge dominates the bill; reducing coincident peaks is the highest-leverage lever, and GSDT adds off-peak energy savings.
- Authorize Nectar for 15-minute interval data (docs.nectarclimate.com)
- Stagger HVAC/equipment startups
- Target the monthly peak-setting interval
Large industrial / high-demand plant
Large loads should evaluate GSLD plus interruptible/standby options and integrate interval data into an energy-management system.
At high demand, voltage-level differentials and interruptible credits materially affect total cost; EDI 810 automates billing into ERP.
- Compare GSLD vs interruptible economics
- Use EDI 810 for automated invoice ingestion
- Build M&V baselines from 15-minute data
Multi-site portfolio operator
Operators with 10+ TECO accounts should enroll in Summary Billing and centralize data through an aggregator for portfolio-wide visibility.
Summary Billing consolidates statements while Nectar centralizes billing + interval data across sites for benchmarking.
- Enroll in Summary Billing (10+ accounts)
- Authorize Nectar across the portfolio (docs.nectarclimate.com)

Historical Rate Trends
TECO has implemented a series of rate adjustments in 2024-2026 driven by an FPSC base-rate settlement and annual fuel/storm clause resets. Rates have trended upward.
January 1, 2026
January 2026 rate adjustment under the FPSC's December 2024 approval, with annual fuel charge reset; a residential customer using 1,000 kWh/month saw an increase of $8.88 across all bill components.
+$8.88/1,000 kWh (residential)March 1, 2025
Temporary storm surcharge introduced to recover 2024 hurricane-season restoration costs, spread over 18 months (March 2025-August 2026).
Storm surcharge addedOverall trend: Upward — multiple base-rate and clause-driven increases through January 2026.
Next expected change: Temporary storm surcharge ends August 2026, lowering bills September-December 2026; further annual fuel-clause adjustments expected at year end.
Cost Optimization Strategies
For TECO C&I customers, savings come from demand management, schedule selection, and load shifting — not supplier shopping. Visibility into 15-minute interval data (via aggregators) is the foundation for demand-charge reduction.
Reduce peak demand (kW)
For: Demand-metered C&I (GSD, GSLD)
On GSD/GSLD schedules, the per-kW billing-demand charge is a major cost driver. Stagger equipment startups and shave coincident peaks to lower billed demand.
Shift load to off-peak (TOD)
For: Customers on or eligible for TOD schedules
Move discretionary load to off-peak hours under GST/GSDT to capture the much lower off-peak energy rate (e.g., GST off-peak 7.514¢ vs on-peak 14.113¢, Jan 2026).
Interval-data monitoring via Nectar
For: All C&I
Authorize Nectar (docs.nectarclimate.com) to pull 15-minute interval data and build load profiles, identify demand peaks, and target measurement & verification for efficiency projects.
Evaluate interruptible/standby tariffs
For: Very large industrial customers
Very large loads that can curtail, or sites with on-site generation, may qualify for discounted interruptible (IS) or standby (SBI/SBF) rates.

Frequently Asked Questions
Does Tampa Electric support Green Button or Share My Data for C&I customers?▾
No. TECO has not implemented Green Button Download My Data, Connect My Data, ESPI, or a branded Share My Data authorization portal. Automated third-party access for commercial customers is handled through Nectar (see docs.nectarclimate.com), or through EDI 810 for business billing.
How can a business automate billing data into its accounting system?▾
Enroll in TECO's EDI 810 program (ANSI X12 v4010). Contact the EDI team at (866) 832-6249, obtain the EDI Implementation Guide, configure a VAN, and run test transactions before activation. This delivers paper-free invoices directly into ERP/accounting systems.
Can we get 15-minute interval data for load analysis?▾
TECO's AMI meters capture 15-minute interval data, but it is not exposed through an official self-service download. The practical paths are authorizing Nectar for interval data access (docs.nectarclimate.com), or using the NISC SmartHub platform. There is no official TECO interval-data API.
Which rate schedules apply to commercial and industrial accounts?▾
C&I accounts take service under General Service Non-Demand (GS/GST), General Service Demand (GSD/GSDT/SBF), and General Service Large Demand (GSLD) schedules, plus interruptible (IS/SBI) and standby options for the largest loads. Demand-metered TOU schedules add a per-kW billing-demand charge on top of energy charges. See the FPSC-approved Retail Tariff Book.
Can Florida C&I customers choose a competitive electricity supplier?▾
No. Florida is a fully regulated market with no retail choice. Tampa Electric is the sole provider in its territory and rates are set by the FPSC; optimization comes from selecting the best-fit TECO tariff and managing demand, not from shopping suppliers.
