HB 50 Missouri House · 2025 Regular Session

Allows electrical corporations to charge for services based on the costs of certain construction work in progress

HB 50 allows Missouri electrical corporations to include construction costs for qualifying clean energy plants in customer rates. It specifically applies to new nuclear or renewable energy facilities under 600 megawatts designed to serve retail customers, excluding plants already operational before August 28, 2025. Utilities must submit detailed cost plans to the Public Service Commission for approval before construction begins, and these costs remain subject to review during rate-setting processes. The bill creates an exception to a general prohibition on charging for unfinished construction work, targeting projects under the "Nuclear Clean Power Act."

MODERATE

The bill was amended from its original version to create a House Committee Substitute that establishes a new process for allowing electrical corporations to include construction work in progress for clean baseload generating plants in their rate base amounts. The changes add specific limitations on cost recovery, introduce refund mechanisms for imprudently incurred costs, and set an expiration date of December 31, 2035, with a potential extension to 2045. These modifications provide clearer regulatory guidance on how utilities can recover construction costs while maintaining oversight to prevent unreasonable rate increases.

Scope change

The bill's scope was expanded to include specific procedural requirements for rate base inclusion and added an expiration mechanism with a sunset provision.

REQUIREMENT

Added new subsection 3 that permits electrical corporations to include construction work in progress in rate base amounts, subject to commission determination of allowable costs and expenditures within the estimated construction period.

ENFORCEMENT

Added refund provisions requiring utilities to return amounts with interest if the commission determines construction costs were imprudently incurred in subsequent proceedings.

TIMELINE

Added expiration date of December 31, 2035, with a provision for potential extension to December 31, 2045 if the commission determines good cause exists after a hearing.

ELIGIBILITY

Removed the previous limitation that excluded plants rated at six hundred megawatts or less from certain provisions, replacing it with the new comprehensive rate base inclusion framework.
