*Depending on the number of existing 100 megawatt electric generating power plants in
Missouri that intend to close, and the level of involvement of the Public Service Commission, the
PSC assumes this could include ‘substantial’ work on their part. Oversight assumes the
additional cost (if any) would not reach the $250,000 threshold.

FISCAL ANALYSIS
ASSUMPTION
Section 393.401 – Electric Power Plants
Officials from the Department of Commerce and Insurance – Public Service Commission
(PSC) state this legislation does not describe what is supposed to be done with the certification
requirement given to the PSC, General Assembly, and the Governor. If the PSC is to just receive
certifications, then the work can be done within current FTE levels. However, if the PSC is to
review and/or approve the certifications, that will require additional, substantial work.
Also, if the certification referenced in the bill requires a formal review, even if abbreviated, to
determine the new generation supplants the old capacity amounts (as specified), there would be
new cases before the PSC, but the number of cases is not known. It is uncertain how many
electric generating power plants of over 100MWs are facing closure next, or how many cases for
replacing capacity (solar, wind, other contracts) come through to replace electric generating
power plant closures. Therefore, the fiscal impact to PSC is undeterminable at this time.
Oversight does not have any information to the contrary. Based on the PSC’s response,
Oversight will reflect the potential cost as $0 or an unknown cost to the Public Service
Commission Fund.
Officials from the Office of Administration - Facilities Management, Design and
Construction (FMDC) assumed there would be a fiscal impact to the State's utility costs.
However, without more information FMDC is unable to calculate the impact this would have on
statewide utility costs for consolidated facilities managed by FMDC. FMDC assumes a $0 to
unknown impact.
Oversight assumes this proposal could increase utility costs to state departments and local
governments if rate changes are made as a result of these new standards. Oversight assumes this
would be an indirect impact and therefore will not show the impact in the fiscal note.
Officials from the Office of the Governor, the Missouri Department of Conservation, the
Missouri House of Representatives, the Missouri Senate, and the Missouri Department of
Transportation assume the proposal will have no fiscal impact on their organizations.
Oversight only reflects the responses received from state agencies and political subdivisions;
however, other electric companies were requested to respond to this proposed legislation but did
not. A listing of political subdivisions included in the Missouri Legislative Information System
(MOLIS) database is available upon request. L.R. No. 1579H.02C

FISCAL DESCRIPTION
Beginning January 1, 2026, this bill specifies that prior to the closure of an existing electric
generating power plant, an electrical corporation, registered and doing business in Missouri,
must first certify that it has secured and placed on the electric grid an equal or greater amount of
replacement reliable electric generation as specified in the bill. Adequate transmission lines must
be in place and the replacement generation fully operational concurrently with the closure of the
existing electric generating plant.
If the replacement electric generation uses some or all of the interconnection facilities used by
the existing generation plant, the replacement facilities must be operational within 180 days of
the closure of the existing plant. If the existing plant is closed as a result of an unexpected or
unplanned cause or event, the electrical corporation must follow the procedures established in the
bill, including filing an application within 120 days with the Public Service Commission
outlining its plan to install replacement reliable electric generation. During any periods where the
replacement power is not fully operational, the electrical corporation must make all reasonable
efforts to contract for additional firm generating capacity to meet the planning reserve margin
requirement of the regional transmission operator. L.R. No. 1579H.02C
Bill No. HCS for HB 476

The bill also specifies that the average of the summer and winter accredited capacity of the new
generation must be greater or equal to the average of the summer and winter accredited capacity
of the existing generation. The Public Service Commission must certify that these requirements
are met. On or before the official date of the existing electric generating power plant closure, the
electric utility company must provide certification to the Commission, the General Assembly,
and the Governor that it has met the necessary requirements.
This legislation is not federally mandated, would not duplicate any other program and would not
require additional capital improvements or rental space.
