Florida City Gas Rate Selection Guide
Florida City Gas (FCG), a Chesapeake Utilities Corporation subsidiary, distributes natural gas to roughly 124,000 customers across Miami-Dade, Brevard, St. Lucie, and Indian River counties. Commercial customers can enroll in an EDI e-Billing program for automated invoice exchange, but interval data, Green Button, and formal third-party data programs are not offered — usage visibility is limited to monthly consumption on bills.
Market Overview
FCG operates as a regulated gas distributor under FPSC oversight, with rates and service rules set in its FPSC-filed tariff. Commercial transportation choice exists for eligible customers (gas supply transportation), managed via the GTS platform, while distribution remains regulated.

Current Rate Schedules
Florida City Gas (FCG, an NextEra/FPL company) bills under an FPSC-approved tariff with General Service (GS) classes tiered by annual therm usage — from GS-1 (under 6,000 therms/year) up to GS-25M (25 million+ therms/year). Every GS account pays a fixed customer charge plus a per-therm distribution charge; the gas commodity is billed either through the Purchased Gas Adjustment (PGA, Rider A) for sales customers or directly by a Third Party Supplier (TPS) for transportation customers. Riders for conservation cost recovery (ECCR), the SAFE pipeline replacement program, and a transportation balancing charge (~$0.0078/therm) also apply.

Rate Recommendations by Use Case
Automated invoice processing for commercial accounts
Enroll commercial accounts in FCG's EDI e-Billing program to feed invoices directly into AP and energy management systems.
EDI 810/820 transactions eliminate manual bill collection for billing data, with SOX/IRS-compliant audit trails — the only automated channel FCG offers.
- Budget 2-4 weeks for trading partner agreement, connection setup, and testing
- Confirm VAN provider options with the EDI department up front
- Remember EDI carries billing data only — no usage detail beyond the invoice
Gas cost management for large facilities
Evaluate transportation service and use the Gas Tracking System for daily consumption visibility.
GTS is the only FCG channel with sub-monthly consumption data, plus settlement, capacity, and imbalance management — valuable for facilities large enough to qualify for transportation choice.
- Call 800.993.7546 to check transportation program eligibility
- Use GTS daily data to manage nominations and avoid imbalance charges
- Compare transportation supply costs against bundled sales service
Portfolio billing data collection
Combine portal PDF downloads with written-authorization requests for multi-site portfolios.
With no API or aggregator integration, portal downloads (12-24 months of history) plus manual requests at 800.993.7546 are the reliable paths; invoice parsing converts PDFs to structured data.
- Register every account in the portal and download bills monthly
- Keep signed customer authorizations on file for third-party requests
- Expect 5-10 business days on manual requests
Future integration planning
Track the Chesapeake SAP migration for new data access capabilities.
The 2023-2026 SAP/IBM CIS consolidation modernizes FCG's platform; while no API commitments exist, enhanced portal and data integration capabilities may follow completion.
- Ask customer service about system enhancements when requesting data
- Re-evaluate access options after the 2026 migration completes
- Advocate for Green Button/ESPI support in discussions with FCG
Cost Optimization Strategies
FCG is a gas-only distribution utility, so the cost levers are commodity procurement (transportation service vs. the PGA), getting onto the right GS usage tier, and managing balancing exposure. Because per-therm distribution rates fall sharply with class size ($0.579 at GS-1 down to $0.440 at GS-25K and lower beyond), confirming correct rate classification is the first check for any C&I account.
Transportation service with a Third Party Supplier
For: All GS-class non-residential accounts; most valuable at GS-6K and above
Non-residential customers can buy commodity from an FCG-authorized TPS instead of paying the Purchased Gas Adjustment. The 2024 levelized PGA ran roughly $0.83-0.85/therm; competitive supply lets larger users hedge and frequently beat that, net of the ~$0.0078/therm transportation balancing charge.
Rate class verification
For: Accounts near the 6,000 / 25,000 / 120,000 therm annual boundaries
FCG assigns GS tiers by annual therm usage. An account whose usage has grown past a tier boundary (e.g., 6,000 or 25,000 therms/yr) should be reclassified — GS-6K's distribution charge is ~16% below GS-1, and GS-25K is ~10% below GS-6K — the higher customer charge usually pays for itself quickly.
Nomination and balancing discipline
For: Transportation (TPS) customers
Transportation customers manage daily nominations through the Gas Tracking System (GTS). Accurate forecasting and weather-normalized nominations avoid imbalance penalties and cash-out exposure under Rider E.
Contract demand and economic development rates
For: Large industrial accounts and new/expanding facilities
Large or expanding facilities can negotiate KDS Contract Demand Service for firm capacity at contracted terms, and qualifying new or expanding industrial loads may access the EDGS economic development schedule for discounted service during ramp-up.
Efficiency and equipment rebates
For: All commercial customers
FCG's energy conservation programs (funded via the ECCR rider already on the bill) offer rebates for high-efficiency gas water heating, cooking, and other commercial equipment — recover charges you are already paying.

Frequently Asked Questions
How do commercial customers automate Florida City Gas billing data?▾
Enroll in FCG's e-Billing EDI program by calling 800.993.7546 or 888.CITYGAS. The program exchanges ANSI X12 transactions — 810 invoices, 820 payments, plus 814 and 824 — with SOX/IRS-compliant record keeping. Setup takes roughly 2-4 weeks including the trading partner agreement, VAN or direct connection, and test transactions. EDI covers billing data only, not usage detail.
Does Florida City Gas offer interval consumption data?▾
No. FCG uses AMR electronic meter reading with monthly reads for billing; 15- and 30-minute interval data is not available through the portal or any third-party channel. The exception is commercial transportation customers enrolled in the Gas Tracking System, who see daily and monthly consumption for nomination and balancing purposes.
Does FCG support Green Button or a public API?▾
No. FCG is not listed in the Green Button Alliance directory, implements no ESPI standard, and maintains no public developer portal or API — the SAP CIS backend exposes no external API layer. Nectar provides API access to this utility's billing data — see docs.nectarclimate.com.
How can a consultant access a client's FCG data?▾
Two paths: a manual data request to customer service at 800.993.7546 with written customer authorization (PDF bill images and billing summaries, 5-10 business day turnaround), or EDI trading partner enrollment on the customer's behalf for recurring invoice data. There is no Share My Data program or standardized authorization workflow.
What is the Gas Tracking System and who can use it?▾
GTS (https://chpk.gastrackingsystem.com/), built by Convergence Solutions, serves commercial gas transportation customers with daily/monthly consumption data, nominations, balancing, settlement and rate information, and capacity/imbalance management. Access is restricted to customers enrolled in transportation service programs — call 800.993.7546 to confirm eligibility.
Where are Florida City Gas rates and tariffs published?▾
FCG's consolidated gas tariff is filed with the Florida Public Service Commission and published at https://www.floridacitygas.com/about-us/rates-and-tariff/ (current 2025 tariff PDF available). The tariff sets service rules, rates, and metering requirements; FPSC filings are also searchable at https://www.psc.state.fl.us/rates-and-tariff.
