What the evidence establishes
Partly. SB 4 requires electrical corporations with over 250,000 customers to develop and submit schedules for customers 'reasonably projected to have above an annual peak demand of one hundred megawatts or more' (for smaller utilities, 'fifty megawatts or more'), which 'should reasonably ensure' those customers pay their share. The duty falls on utilities, and the law does not name data centers.
Biggest limitation
The text of the Commission's orders approving the Ameren Missouri and Evergy large load tariffs, including the 12-year minimum term and collateral terms the PSC describes; those orders could not be read.

Evidence

What the evidence supports

The truly agreed text of SS#2 SB 4 says each electrical corporation providing electric service to more than 250,000 customers shall develop and submit to the commission schedules applicable to customers 'reasonably projected to have above an annual peak demand of one hundred megawatts or more', and that the schedules should reasonably ensure such customers' rates reflect their representative share of the costs incurred to serve them and prevent other customer classes' rates from reflecting any unjust or unreasonable costs arising from service to them. Utilities with 250,000 or fewer customers as of 1 January 2025 must do the same for customers 'reasonably projected to have above an annual peak demand of fifty megawatts or more', and the commission may order similar tariffs for customers below those levels. The statute's threshold wording combines 'above' and 'or more'; it is quoted here as written. The purpose the PSC describes matches the text. The text places the duty on utilities to develop and submit schedules rather than on the Commission to adopt rates, and it defines the class by projected peak demand without naming data centers.

Still unknown

The text of the Commission's orders approving the Ameren Missouri and Evergy large load tariffs, including the 12-year minimum term and collateral terms the PSC describes; those orders could not be read.
