Florida Public Utilities Company (FPUC) Rate Selection Guide
Florida Public Utilities Company (FPUC), a Chesapeake Utilities Corporation subsidiary founded in 1924, serves roughly 136,000 Florida customers — about 103,000 natural gas and 33,000 electric. Data access is limited to a basic online billing portal: FPUC offers no Green Button, EDI, interval data, or third-party authorization programs, so C&I teams rely on manual PDF collection and account-manager arrangements.
Market Overview
Florida's retail electricity market is regulated; FPUC provides bundled electric and natural gas service under FPSC oversight, with rates set through filed tariffs (FPU Electric Tariff and FPU Consolidated Natural Gas Tariff).

Current Rate Schedules
Florida Public Utilities (FPUC, a Chesapeake Utilities company) serves electric customers in its Northeast (Fernandina Beach area) and Northwest (Marianna area) Florida divisions plus natural gas across central/south Florida. Electric rate classes run from GS (small commercial, energy-only) through GSD, GSLD, and GSLD1 (industrial), all layered with FPSC cost-recovery clauses (purchased power, conservation, storm protection). FPUC's 2024-2025 rate case (Docket 20240099-EI) reset base rates effective March 2025 — e.g., GS customer charge ~$40.00, GSD demand charge ~$6.89/kW, GSLD ~$9.86/kW — while the purchased power adjustment (roughly $0.07-0.08/kWh in 2025) typically exceeds base energy charges. Gas customers are billed under GS-1 through GS-8 tiers (or GTS transportation equivalents) plus the PGA.
Effective: March 20, 2025 · Full Tariff Book →
| Schedule | Type | Applicability | Structure | Rate |
|---|---|---|---|---|
| GS — General Service (Electric) | commercial | Small commercial electric accounts without demand metering | Customer charge ~$40.00/month + base energy charge ~$0.04668/kWh + purchased power adjustment (~$0.079/kWh in 2025) and cost-recovery clauses; no demand charge. | ~$0.12/kWh all-in delivery+fuel; see tariff |

| GSLD / GSLD1 — General Service Large Demand (Electric) | industrial | Large commercial (GSLD) and industrial (GSLD1) accounts; GSLD1 has only a handful of customers and includes a kVAR reactive demand charge | GSLD: customer charge ~$241.70/month, demand ~$9.86/kW, base energy ~$0.00390/kWh. GSLD1: customer charge ~$1,183.57/month, demand ~$2.74/kW plus $0.53/kVAR reactive charge; nearly all cost recovered through demand. | —+ GSLD ~$9.86/kW; GSLD1 ~$2.74/kW + $0.53/kVAR |

| GS-1 through GS-8 / GTS — Natural Gas General Service & Transportation | commercial | Commercial and industrial gas accounts tiered by annual therm usage; GTS variants for customers buying gas from third-party marketers | Customer charge + per-therm distribution charge declining with tier, plus PGA (sales customers; 2025 cap ~$1.00/therm) or marketer-billed commodity (GTS transportation customers) and conservation/swing service charges. | See consolidated gas tariff for current per-therm rates |
Rate Recommendations by Use Case
C&I billing data collection
Build a monthly PDF collection workflow from the MyAccount portal.
With no API, EDI, or structured export, the portal's ~12-month PDF history is the only first-party source; downloading monthly prevents history loss and feeds invoice parsing.
- Register every account with its 12-digit account number
- Download new bills monthly before older ones roll off
- Extract charges and consumption via invoice-parsing tooling
Portfolio energy management
Negotiate direct data feeds with FPUC's business team for portfolios over ~5 accounts.
Manual per-account collection doesn't scale; FPUC's commercial team (888.220.9356) can arrange ad-hoc CSV/Excel historical reports for significant accounts, even without a formal program.
- Document data elements, frequency, and history depth in a written request
- Lead with annual consumption and account count to justify the effort
- Expect 2-4 weeks for setup with no SLA
Interval-data-dependent projects
Plan around the absence of interval data at FPUC facilities.
FPUC offers no 15-/30-minute data, so demand analysis must use monthly bill data or customer-installed submetering; utilities like FPL and Duke Energy Florida offer Green Button if site-level granularity is essential.
- Deploy submeters or building-level monitoring where interval visibility matters
- Ask the account manager whether any hourly data exists for large accounts
- Watch the SAP/IBM CIS rollout (2025-2026+) for new capabilities
Third-party data authorization
Standardize a written-authorization workflow for client data requests.
FPUC has no Share My Data program; a signed authorization letter plus a customer service request (800.427.7712) reliably yields bill copies in 5-10 business days.
- Keep signed authorization letters on file per account
- Request 12 months of history in the initial pull
- Set monthly reminders since no recurring feed exists
Cost Optimization Strategies
FPUC bills stack base rates with FPSC cost-recovery clauses, and the purchased power adjustment dwarfs base energy charges on the electric side — so demand management, correct rate class placement, and (for gas) transportation service drive most savings. The 2025 rate case raised customer and demand charges materially, increasing the payoff for peak control.
Demand charge management
For: GSD, GSLD, and GSLD1 electric accounts
GSD pays ~$6.89/kW and GSLD ~$9.86/kW of monthly billing demand. Staggering HVAC starts, sequencing equipment, and monitoring demand against a target cap directly cuts the demand line item every month.
Rate class and TOU review
For: Small/mid commercial electric accounts
Accounts near the GS/GSD boundary should compare bills under both structures — high-load-factor accounts often win on demand-billed rates while low-load-factor accounts may not. Ask FPUC about current TOU rider availability for shiftable loads.
Power factor correction
For: GSLD1 industrial accounts and large motor loads
GSLD1 bills reactive demand at ~$0.53/kVAR. Installing capacitor banks to hold power factor near unity eliminates this charge and can reduce billed kW.
Gas transportation service (GTS)
For: GS-2 and larger natural gas accounts
Commercial gas customers can switch from FPUC sales service (PGA-priced, capped near $1.00/therm in 2025) to GTS transportation, buying commodity from a marketer at negotiated prices while FPUC delivers.
Conservation program rebates
For: All C&I electric and gas customers
FPUC's FPSC-approved conservation programs (funded by the conservation clause already on every bill) rebate high-efficiency HVAC, lighting, and gas equipment for business customers — file for incentives on planned upgrades.

Frequently Asked Questions
How do C&I customers access FPUC billing data?▾
Register each account at https://myaccount.fpuc.com/ using the 12-digit account number, service address, phone number, and the last two payment amounts for verification. The portal shows roughly 12 months of bills with charges, rates, and usage; export bills as PDF via the portal or browser print-to-PDF. There is no CSV/XML export and no API.
Does FPUC provide interval or smart meter data?▾
No. FPUC reads meters monthly for billing and offers no customer access to 15-minute, 30-minute, daily, or real-time usage. There is no AMI data portal, and the Florida PSC does not mandate Green Button or ESPI. If interval granularity is essential, on-site submetering is the practical workaround.
Does FPUC support EDI for commercial billing?▾
No. FPUC is absent from the DOE's list of utilities offering EDI, publishes no 810/820/867 specifications or trading partner forms, and its FPSC-filed tariffs contain no EDI provisions. High-value commercial accounts can ask the sales team at 888.220.9356 whether a custom arrangement is possible, but nothing is advertised.
How can a consultant or energy manager get a client's FPUC data?▾
Through manual authorization only. Either the customer downloads bill PDFs from MyAccount and shares them, or the third party calls 800.427.7712 with a signed customer authorization letter and requests bill copies (expect 5-10 business days). FPUC has no Share My Data portal, ESPI API, or aggregator partnerships.
Can large C&I accounts get structured data from FPUC?▾
Possibly. The commercial team (888.220.9356) handles ad-hoc requests for monthly detailed usage reports and historical billing in CSV/Excel format. Document your data elements, frequency, and history depth in writing; initial responses take 5-10 business days and custom solutions 2-4 weeks, with no guaranteed SLA.
Will FPUC's data access improve?▾
Watch the Chesapeake Utilities SAP/IBM Customer Information System project — the company's largest-ever technology initiative, announced June 2023 with completion expected 2025-2026. It will modernize the customer portal across subsidiaries including FPUC and could enable future APIs, though no Green Button, ESPI, or API commitments have been made.
