Ameren SEC Filings

Ameren Corporation and its utility Ameren Missouri report that the Missouri Public Service Commission has approved an amended non-unanimous global agreement for their large primary service tariff, known as the Large Load Customer Rate Plan. The order covers new facilities with expected monthly demand of at least 75 megawatts and existing customers expanding demand by at least 75 megawatts.

These large customers must sign electric service agreements with a minimum 12-year term plus a ramp period of up to five years, pay demand charges on at least 80% of contracted capacity, and give 24 months’ notice before terminating service or pay exit fees tied to their minimum monthly bill. The order also requires collateral equal to two years of minimum bills, with up to 60% relief for stronger credits.

An earnings sharing mechanism applies if Ameren Missouri’s return on equity exceeds the staff-recommended midpoint of 9.74%, with 65% of the excess set aside to benefit retail customers. The order also allows partial revenue deferral in certain force majeure events.
