Powering Missouri Growth Plan – Five Critical Customer Protections
Ameren Missouri's growth plan helps attract jobs and investment to Missouri while providing robust protections to customers
As a part of Ameren Missouri's Powering Missouri Growth Plan, data centers and other large users are required to pay their fair share of grid enhancements and energy costs. The plan, unanimously approved by the Missouri Public Service Commission last fall, applies to high-usage customers whose expected monthly peak power demand is 75 megawatts or more. With data center developers announcing projects throughout Ameren Missouri's service territory, the plan outlines five critical protections for the company's residential customers.
Large customers are required to pay their fair share.
Ameren Missouri’s Powering Missouri Growth Plan, in alignment with 2025's Senate Bill 4, requires new large load businesses to pay their fair share of service costs, protecting other customers from unjust or unreasonable charges.No special discounts or incentives.
Large load customers do not receive discounted rates or incentives from Ameren Missouri, ensuring fairness across all customer classes. Even if they use less electricity than expected, large load customers must pay a minimum monthly demand charge of at least 80% of their contracted maximum electric demand.Strong financial protections are required.
Large load customers must pay upfront 100% of all costs associated with hooking up to the energy grid. They also must pay upfront financial security and collateral requirements equivalent to two years of minimum monthly bills.Long-term commitments provide stability.
Long-term contracts of at least 12 and up to 17 years are required for large load customers, which unless terminated by the customer or Ameren Missouri at the end of that term, automatically extend for terms of five years each. The contracts also include substantial early termination fees if minimum obligations are not met.Customers get the benefits.
If profits exceed authorized levels, revenues are shared with other customer classes, including income-eligible customers.
