Statewide

Missouri's data storage center exemption (RSMo 144.810, enacted by S.B. 149 in 2015, revised 2018) waives state and local sales and use tax on utilities, equipment and construction materials for new centers investing $25 million and adding 10 jobs at 150% of the county average wage within 36 months (up to 15 years), or for expansions of $5 million and 5 jobs (up to 10 years), capped at the projected 10-year net fiscal benefit. The revisor shows no amendment since 2018. (Missouri Revisor of Statutes, Aug. 28, 2018; Missouri Independent, June 29, 2026) S.B. 4 (2025) added RSMo 393.130.7, effective Aug. 28, 2025: utilities with more than 250,000 customers must file tariffs for customers expected to reach 100 MW peak demand (50 MW for smaller utilities) so those customers pay their share and other classes do not bear unjust costs; the PSC may extend this to smaller loads. (Missouri Revisor of Statutes, Aug. 28, 2025; Missouri Public Service Commission, 2026) PSC File No. EO-2025-0154 (Evergy Missouri Metro and Evergy Missouri West): the order issued Nov. 13, 2025, effective Dec. 13, 2025, approved the Large Load Power Service plan for loads of 75 MW or more, with a 12-year minimum term plus an optional ramp of up to 5 years, collateral of two years of minimum bills and exit fees; a separate proposal from PSC staff and the Public Counsel was not adopted.
