Capital Program Planning for Florida Gas Utilities

by | Oct 21, 2026

Florida · Natural Gas Utilities

Florida's gas system is growing with the state — and every mile of it competes for capital.

Florida's natural gas utilities are expanding into one of the fastest-growing states in the country while replacing legacy cast-iron and bare-steel pipe, absorbing a $1.2 billion pipeline build to relieve south-Florida supply constraints, and defending rate cases before the PSC. Each of those forces reshuffles the projects on your list. Invizion helps gas utilities re-sequence a capital portfolio in a click — and defend every decision.

The bottom line: Florida's gas utilities aren't fighting a ban — they're racing growth: expanding into one of the nation's fastest-growing states, replacing legacy pipe on a rider clock, and leaning on interstate pipelines they don't control. The ones that stay ahead will re-sequence capital as fast as the state changes.

The Florida Landscape

Four forces are moving your project list at once

Florida's gas story is different from the Northeast or California: the pressure here is growth and supply, not a looming ban. But the capital math is just as unforgiving — the plan you approved last year may already be the wrong plan.

System Integrity — Aging Pipe

Legacy cast iron and bare steel, on a replacement clock

Florida's newer systems sit alongside decades-old mains in its urban cores. Peoples Gas recovers the cost of retiring cast-iron and bare-steel pipe through a dedicated replacement rider — the 2023 rate order moved $11 million of that investment into base rates.3

Florida City Gas runs a parallel SAFE (Safety, Access and Facility Enhancement) program for accelerated recovery of replacing older portions of its roughly 3,800 miles of distribution main.64 Every mile retired is a mile that has to be scheduled, funded, and defended.

Decarbonization — Preemption

The gas ban Florida law won't allow

Unlike states running "future of gas" dockets, Florida has moved the other way. HB 919 (2021) prohibits any municipality, county, or special district from restricting the fuel sources of energy delivered to customers, and voided local policies that did.8

That protects gas-line extensions and new hookups — but it does not remove the long-horizon question. Throughput is dominated by power generation, not homes; residential and commercial burn is only about 5% of the state's gas use,9 so the LDC's growth case rests on winning connections in a competitive fuel market.

Supply — Pipeline Dependence

A state that consumes gas but barely produces it

Florida burned about 1.69 trillion cubic feet of natural gas in 2024 but produced only 356 million — a fraction of one percent of what it uses.109 Nearly every molecule arrives on long interstate pipelines, leaving the peninsula exposed to capacity constraints and storm risk.

South Florida is already supply-constrained: Chesapeake Utilities' $1.2 billion, 24-inch Florida Energy Pathway from Palm Beach to Miami-Dade — anchored by roughly 250,000 dekatherms/day of firm commitments — is being built to relieve it by 2030.7

Capital — Recovery & Rates

Rising bills meet a full capital docket

The capital is being spent and recovered through the PSC. Peoples Gas won a $118 million base-rate increase in 2023 at a 10.15% ROE midpoint;3 Florida City Gas landed a $23.3 million increase at a 9.50% ROE the same year.6

Florida residential gas already runs about $25.37 per thousand cubic feet — well above the national norm.11 Every new project has to earn its place against that affordability pressure.

Who Delivers Florida's Gas

Four investor-owned LDCs and a set of municipal districts

Florida's gas distribution is led by four PSC-regulated investor-owned utilities — two of them now under Chesapeake Utilities — alongside city- and district-owned systems that set their own rates. The pressures are shared; the accountability path differs.

Investor-owned gas LDCs

Rates & capital recovery regulated by the Florida PSC

Peoples Gas System (TECO / Emera) 500,000+ customers · statewide · largest LDC2
Florida City Gas (Chesapeake Utilities) ~125,000 customers · 8 counties · ~3,800 mi main5
Florida Public Utilities (Chesapeake Utilities) ~229,000 gas customers (2025)6
St. Joe Natural Gas Company Small IOU · Port St. Joe / Gulf County · PSC-regulated14

Chesapeake Utilities now owns two of the four IOUs — it bought Florida City Gas from NextEra Energy for $923.4 million, closing December 1, 2023.4

Municipal & special-district systems

Rates set by local boards, not the PSC

Lake Apopka Natural Gas District 30,000+ customers · West Orange & South Lake12
Okaloosa Gas District Public gas district · NW Florida panhandle15
Clearwater Gas System Municipal system · City of Clearwater / Pinellas16

Municipal and special-district systems set their own rates through local boards and are exempt from PSC rate regulation — but they carry the same aging-pipe and growth pressures as the investor-owned LDCs.12

Rate-Setting & Oversight

Every capital dollar has to be defensible

Whether you answer to the Public Service Commission or a municipal board, the question is the same: why this project, why now, why at this cost?

  • Florida Public Service Commission (PSC) regulates the rates, capital recovery, and safety programs of the investor-owned gas LDCs — Peoples Gas, Florida City Gas, Florida Public Utilities, and St. Joe Natural Gas.3
  • Peoples Gas 2023 rate order: the PSC approved a $118 million base-revenue increase (about $107 million net after transferring cast-iron/bare-steel investment into base rates), effective January 2024, at a 10.15% ROE midpoint and 54.7% equity.3
  • Florida City Gas 2023 rate case: a $23.3 million increase (including $14.1 million incremental) at a 9.50% ROE, which also folded the SAFE replacement rider into base rates.6
  • Infrastructure-replacement riders: Peoples Gas' cast-iron/bare-steel replacement rider and Florida City Gas' SAFE program provide accelerated cost recovery for retiring aging pipe — the primary capital-recovery mechanism for system-integrity work.36
  • State preemption (HB 919, 2021): Florida law bars local governments from restricting the fuel sources delivered to customers, protecting gas-line extensions from local bans.8

Funding The Build

In Florida, capital recovery is mostly rider-based

Federal gas-modernization dollars are aimed at municipal systems, so Florida's investor-owned LDCs fund most of their build through PSC-approved riders and rate cases — and through private pipeline capital. The constraint is sequencing, not just access to money.

  • Cast-iron / bare-steel replacement rider (Peoples Gas): accelerated recovery for retiring legacy pipe; the 2023 order transferred $11 million of that investment into base rates and the rider continues for ongoing work.3
  • SAFE program (Florida City Gas): accelerated recovery of the cost of replacing older portions of the distribution system; $5.3 million of SAFE investment was moved into base rates in the June 2023 rate order.6
  • Florida Energy Pathway ($1.2B): a 24-inch intrastate pipeline from Palm Beach to Miami-Dade, in service by 2030, financed with private capital — Chesapeake Utilities is selling up to a 49% ownership interest to partners.7
  • PHMSA NGDISM grants ($200M/yr, $1B over five years): federal pipe-modernization money — but limited to municipal and community-owned utilities, so Florida's large investor-owned LDCs recover replacement costs through riders instead.13

Where Invizion Fits

Turn Florida's gas-system decisions into a defensible capital plan

Invizion is scenario-based capital portfolio optimization built for utilities. When a replacement mandate accelerates, throughput forecasts shift, or a decarbonization ruling lands, you don't re-plan by hand for weeks — you model it and decide with a record to stand behind.

1

Model the “what-if” before it's forced on you

A faster main-replacement schedule, a gas-line-extension ban, an RNG mandate — build the scenario and see the impact on the whole portfolio, side by side with today's plan.

2

Re-sequence 500 projects in a click

When priorities move, Invizion re-orders the portfolio automatically — accelerating, stretching, or deferring projects against the constraints you set, not weeks of spreadsheet surgery.

3

Give regulators or your board a defensible record

Every prioritization and trade-off is captured. When you're asked “why this project, why now,” the answer is documented — not reconstructed after the fact.

Florida's Gas Sector, In Brief

Questions Florida gas utility leaders are asking

Short, sourced answers — the same facts we dig into with utilities looking at their capital programs.

How many natural gas customers does Florida have?
About 1.02 million natural gas customers in 2024, roughly 946,000 of them residential. Peoples Gas System is the largest distributor, with more than 500,000 customers statewide.12
Who are Florida's largest natural gas utilities?
Peoples Gas System (a TECO / Emera company), Florida City Gas and Florida Public Utilities (both now owned by Chesapeake Utilities), and the small investor-owned St. Joe Natural Gas — plus municipal systems such as Lake Apopka Natural Gas District, Okaloosa Gas District, and Clearwater Gas System.256
Can Florida cities ban natural gas in new buildings?
No. Florida's HB 919 (2021) preempts municipalities, counties, and special districts from restricting the fuel sources of energy delivered to customers and voided local policies that did.8
How do Florida utilities pay to replace old gas pipe?
Mainly through PSC-approved riders: Peoples Gas uses a cast-iron/bare-steel replacement rider and Florida City Gas runs its SAFE program, both giving accelerated recovery for retiring aging mains.36
Why is Florida building the $1.2 billion Florida Energy Pathway?
Florida produces almost no natural gas of its own and about 86% of what it uses goes to power generation, so the peninsula depends on interstate pipelines. The 24-inch Florida Energy Pathway is being built to relieve south-Florida supply constraints and serve continued growth by 2030.7109
How does Invizion help Florida gas utilities plan capital?
Invizion is scenario-based capital portfolio optimization for utilities. It lets you model how a growth surge, a pipeline commitment, or an accelerated pipe-replacement schedule reshuffles your whole project list, re-sequence the portfolio automatically, and keep a defensible record of every decision for the PSC or your board.
