SB 838 Missouri Senate · 2026 Regular Session

Modifies certain provisions relating to the means of energy production

SB 838 modifies Missouri's renewable energy standard by establishing phased requirements for electric utilities: 2% renewable energy by 2013, increasing to 5% by 2017, 10% by 2020, and 7.5% annually starting in 2021. At least 2% of each utility's requirement must come from solar energy. The bill also creates an "accelerated renewable buyer" program for large commercial customers (over 80 average megawatts) that contract directly for renewable energy, allowing them to exclude that energy from utility compliance calculations and receive exemptions from renewable energy compliance costs. These changes directly affect Missouri's electric utilities and qualifying large commercial energy buyers.

MINOR
The amendment shifts the bill's focus from restricting public utility rate increases to prohibiting electrical corporations from billing for 'construction work in progress' on nuclear power facilities. This change removes a specific constraint on rate hikes for zero-emission projects and replaces it with a new rule preventing nuclear plant developers from charging customers for costs incurred before the facility is completed.
Scope change
The amendment changes the target of the regulation from the Public Service Commission's ability to set rates to the billing practices of electrical corporations regarding nuclear power projects.
REQUIREMENT

Deleted a provision that forbade the Public Service Commission from increasing allowed returns on equity for electric utilities solely because they are building zero-emission facilities.

Added a new requirement prohibiting electrical corporations from demanding charges for construction work in progress on any nuclear power generating facility.
