SUMMARY ANALYSIS
The Public Service Commission (PSC) has broad jurisdiction over the rates and service of public (investor-
owned) electric and natural gas utilities in Florida. The PSC sets rates for these utilities through various
mechanisms to allow the utilities to recover their legitimate costs of providing service, including a return on the
utility’s prudent capital investments.
Renewable natural gas (RNG) is the gaseous product of the decomposition of organic matter, processed into a
pipeline-quality gas that is fully interchangeable with conventional natural gas. Primary sources of RNG include
landfills, livestock operations, and wastewater treatment facilities. Hydrogen fuel is produced predominantly
from natural gas but can also be produced, at a greater cost, by electrolysis powered by renewable energy.
The bill provides that the PSC may create an experimental mechanism to facilitate investment in energy
infrastructure consistent with the legislature’s intent to promote renewable energy and the definition of
“renewable natural gas.” Thus, it appears that the bill authorizes the PSC to create an experimental
mechanism to promote investment in renewable natural gas infrastructure.
The bill does not appear to impact state or local government revenues or expenditures.
The bill provides an effective date of July 1, 2024.
This docum ent does not reflect the intent or official position of the bill sponsor or House of Representatives .

FULL ANALYSIS
I. SUBSTANTIVE ANALYSIS
A. EFFECT OF PROPOSED CHANGES:
Current Situation
Rate Setting for Public Utilities
The Public Service Commission (PSC) has broad jurisdiction over the rates and service of public
(investor-owned) electric and natural gas utilities in Florida.1 Under this broad grant of authority, and
through more specific grants of authority in Chapter 366, F.S., the PSC sets rates for such utilities
through various mechanisms, each of which is established in a separate administrative proceeding:
Base rates (set for electric and natural gas utilities)
o Adjusted as needed in a general rate case, conducted through a formal evidentiary
hearing for electric utilities and either a formal or informal proceeding for natural gas
utilities.2
o Designed to recover most operations and maintenance expenses, depreciation expense
(recovery of capital investment over time), and a return on capital investment.
Fuel and purchased power cost recovery charges (set for electric utilities only)
o Adjusted annually through a formal evidentiary hearing.
o Designed to recover the costs of fuel and the energy component of wholesale power
purchases.
o By PSC order, may include recovery of certain capital investments, including a return on
investment.
Purchased gas adjustment charges (set for natural gas utilities only)
o Adjusted annually through a formal evidentiary hearing.
o Designed to recover the costs of wholesale natural gas purchases.
Capacity cost recovery charges (set for electric utilities only)
o Adjusted annually through a formal evidentiary hearing.
o Designed to recover costs of the capacity component of wholesale power purchases.
o By statute, may include recovery of certain costs related to development of new nuclear
power plants, including a return.3
Environmental cost recovery charges (set for electric utilities only)
o Adjusted annually through a formal evidentiary hearing.
o Designed to recover costs to comply with government-mandated environmental
standards.
o By statute, may include recovery of certain capital investments, including a return on
investment.4
Storm protection plan cost recovery charges (set for electric utilities only)
o Adjusted annually through a formal evidentiary hearing.
o Designed to recover costs to implement PSC-approved storm protection plans.
o By statute, may include recovery of certain capital investments, including a return on
investment.5
Energy conservation and efficiency cost recovery charges (set for electric and natural gas
utilities)
o Adjusted annually through a formal evidentiary hearing.
o Designed to recover costs of implementing PSC-approved energy conservation and
efficiency programs.

2 A natural gas utility or a public electric utility whose annual sales to end -use customers amount to less than 1,000 gigawatt hours may
request that the PSC process the utility’s petition for rate relief using an informal “proposed agency action” procedur e. S. 366.06(4),

As required by law, the PSC sets base rates to allow utilities to recover their legitimate costs of
providing service (not otherwise recovered through another cost recovery mechanism), including a
return on the utility’s prudent capital investments (“rate base”). 6 In each rate case, the PSC sets a
“reasonable” rate of return on equity for each utility to apply to its rate base. This rate is typically
applied to the utility’s investments that the PSC allows to be recovered through cost recovery
mechanisms other than base rates.
The PSC is also authorized to establish certain experimental rates.7
Renewable Energy
Florida law provides that it is in the public interest to promote the development of renewable energy
resources to help diversify fuel types for electric production, minimize the volatility of fuel costs,
encourage investment within the state, improve environmental conditions, and make Florida a leader in
new and innovative technologies.8 The law defines renewable energy as energy produced from a
method that uses one or more of the following fuels or energy sources: hydrogen produced or resulting
from sources other than fossil fuels, biomass, solar energy, geothermal energy, wind energy, ocean
energy, and hydroelectric power.9
Renewable Natural Gas
Renewable natural gas (RNG) is the gaseous product of the decomposition of organic matter,
processed into a pipeline-quality gas that is fully interchangeable with conventional natural gas. Primary
sources of RNG include landfills, livestock operations, and wastewater treatment facilities.10
In 2021, the Legislature added the term “renewable natural gas” to Florida law and defined it as
“anaerobically generated biogas, landfill gas, or wastewater treatment gas refined to a methane content
of 90 percent or greater which may be used as a transportation fuel or for electric generation or is of a
quality capable of being injected into a natural gas pipeline.” The legislation authorized the PSC to
approve cost recovery for the purchase of RNG by natural gas public utilities, even if pricing exceeds
the current market price of natural gas, if the PSC deems the purchase to be reasonable and prudent. 11
Effect of the Bill
The bill provides that the PSC may create an experimental mechanism to facilitate investment in
energy infrastructure consistent with the legislature’s intent to promote renewable energy and the
definition of “renewable natural gas.” Thus, it appears that the bill authorizes the PSC to create an
experimental mechanism to promote investment in renewable natural gas infrastructure. Under the bill,
the experimental mechanism must be consistent with part of the structure set forth in current law for
storm protection plan cost recovery.12, 13

12 Section 366.96(7), F.S., provides that after the PSC approves a utility’s transmission and distribution storm protection plan ,
proceeding with actions to implement the plan shall not constitute or be evidence of imprudenc e. Furthermore, this section provides that
The PSC shall conduct an annual proceeding to determine the utility’s prudently incurred transmission and distribution storm protecti on
plan costs and allow the utility to recover such costs through a charge separate and apart from its base rates, to be referred to as the
storm protection plan cost recovery clause. If the PSC determines that costs were prudently incurred, those costs will not be subject to
disallowance or further prudence review except for fraud, perjury, or intentional withholding of key information by the public utility. S.
366.96(7), F.S.
13 Section 366.96(8), F.S., provides that annual transmission and distribution storm protection plan costs may not include costs
recovered through the public utility’s base rates and must be allocated to customer classes pursuant to the rate design most recently
approved by the PSC. S. 366.96(8), F.S.

IV. AMENDMENTS/COMMITTEE SUBSTITUTE CHANGES
On January 30, 2024, the Energy, Communications & Cybersecurity Subcommittee adopted a proposed
committee substitute (PCS) and one amendment to the PCS and reported the bill favorably as a committee
substitute. The PCS replaced all of the provisions of the original bill with a provision authorizing the PSC to
create an experimental mechanism to facilitate investment in energy infrastructure consistent with the
legislature’s intent to promote renewable energy and the definition of “renewable natural gas.” The amendment
modified the date by which the PSC must propose an implementing rule.
