Current Rate Schedules
Rates are set by the FPSC-approved Peoples Gas tariff. Effective January 2026 (following the Docket 20230023-GU settlement approved Oct 7, 2025), base rates increased modestly: typical GS-1 (smaller commercial) bills rose about 2% and typical GS-4 (larger commercial) bills about 3%, including fuel. Bills combine a fixed monthly customer charge, a per-therm distribution charge that decreases per therm as the sales class rises, and a Purchased Gas Adjustment (PGA) pass-through of commodity cost. Exact per-therm and customer charges by class are published in Tariff Section 7; transportation (NGTS) customers pay distribution-only charges and procure gas separately.

Rate Recommendations by Use Case
Small/mid commercial business (restaurants, small manufacturers)
Ensure the account sits on the correct GS class for actual annual therms and automate billing with EDI 810.
Per-therm distribution charges fall as the class rises, so matching usage to class minimizes distribution cost; the 2026 GS-1 increase is modest (~2%).
- Verify annual therm usage against class thresholds
- Enroll in EDI 810 for automated invoice processing
- Apply for commercial efficiency rebates on gas equipment
Large industrial / high-volume user
Evaluate Natural Gas Transportation Service (NGTS) to unbundle the commodity and move to the lowest per-therm distribution class (GS-4/GS-5).
High-volume users get the lowest per-therm distribution rate and can often beat the utility PGA by buying gas from a marketer under transportation service.
- Confirm transportation eligibility with Gas Transportation Services (800-264-8026)
- Model marketer pricing vs. the PGA
- Use the Quorum Portal for nominations and balancing
Multi-site C&I needing programmatic billing/usage
Use EDI 810 trading-partner setup or the TECO developer portal to centralize billing data across sites; authorize a consultant via the Third-Party Verification Agreement.
EDI 810 delivers same-day standardized invoices for automated multi-site processing; third-party authorization or developer APIs enable consultant access.
- Stand up a VAN and complete EDI 810 testing
- File Third-Party Verification Agreements (valid ~12 months) per account
- Register at developer.tecoenergy.com to evaluate available APIs

Cost Optimization Strategies
For a regulated gas LDC, C&I cost optimization centers on correct rate-class assignment, transportation service for large users, efficiency to cut therms, and managing the commodity (PGA) component.
Optimize sales-class assignment
For: All C&I gas accounts
Because per-therm distribution charges decline as the class rises, confirm your account is on the class that matches actual annual therm usage; consolidating or aggregating meters can shift you to a lower per-therm class.
Evaluate Natural Gas Transportation Service (NGTS)
For: Large-volume C&I (transportation-eligible)
Large-volume customers can buy the gas commodity from a marketer and take delivery-only service, potentially beating the utility PGA and gaining price certainty.
Capture commercial efficiency rebates
For: C&I upgrading gas equipment
Use Peoples Gas rebates for high-efficiency water heating, cooking, space conditioning, and CHP to lower therm consumption and bills.
Adopt EDI 810 and budget billing
For: Commercial/business customers
Use EDI 810 to automate invoice processing and auditing, and budget billing to smooth seasonal swings, improving cost control and catching billing errors.

Frequently Asked Questions
How do C&I customers receive billing data programmatically from Peoples Gas?▾
The primary programmatic channel is ANSI X12 EDI 810 (v4010) invoices, delivered same-day as the paper bill to EDI-capable business customers or authorized trading partners via a VAN. Alternatively, the TECO portal supports PDF/CSV export of up to 24 months of billing history, and the TECO developer portal offers OAuth 2.0 APIs upon approval.
Does Peoples Gas support Green Button or sub-daily interval data?▾
Not confirmed. Peoples Gas has deployed AMR (~99%) and is rolling out Itron Intelis 250 smart meters, but a standardized Green Button/ESPI feed and sub-daily interval download for gas were not found in public documentation. The portal provides daily and monthly usage; verify current capabilities with Business & Commercial (866-832-6249).
Can large commercial users choose their gas supplier?▾
Florida's gas market is regulated, but large-volume customers can use Natural Gas Transportation Service (NGTS): buy the gas commodity from a third-party marketer while Peoples Gas provides regulated delivery only. Nominations and balancing are managed through the Quorum Portal; contact Gas Transportation Services (800-264-8026).
What commercial rate schedules apply to my business?▾
Peoples Gas uses tiered general service sales classes by annual therm consumption: SGS (small) and GS-1 through GS-5 (e.g., GS-1 ~2,000-9,999 therms/yr; GS-4 ~250,000-499,999 therms/yr), plus transportation service for large users. Rates and the customer charge step up by class; see the FPSC-approved tariff (Section 7, Rate Schedules).
How does a third party get authorized to access my account data?▾
The customer completes TECO's Third-Party Verification Agreement specifying the data to be shared (billing, usage, account/disconnect history) and submits it to TECO. Authorization is valid ~12 months. The authorized party then requests data by account number, service address, and meter number, receiving it in about 3-5 business days.
