Key Issues
- —
Ameren Missouri electric rate case outcome and grid modernization cost recovery: The MoPSC is evaluating the appropriate return on equity and capital structure for Ameren Missouri following its 2024-2025 rate filing, with the Office of Public Counsel contesting the prudence of certain renewable transition expenditures and challenging proposed ROE levels above 9.8%.
- —
Integrated Resource Plan compliance and coal retirement sequencing for Evergy Missouri West: The MoPSC is monitoring Evergy's IRP commitments to retire coal generation at the Hawthorn and Montrose facilities while ensuring resource adequacy through SPP market participation and new wind capacity additions in western Missouri.
- —
Natural gas infrastructure investment and decarbonization tension for Spire Missouri: The commission faces pressure from environmental intervenors to scrutinize long-term capital recovery for gas distribution infrastructure given potential stranded asset risk, while Spire seeks continued approval of its Infrastructure System Replacement Surcharge for mandatory pipeline safety upgrades.
- —
Renewable energy standard implementation and net metering policy reform: Missouri's Renewable Energy Standard at 15% by 2021 has been technically met, but the MoPSC is engaged in ongoing proceedings regarding the structure of net metering compensation for distributed solar customers, including potential shift to avoided cost or time-of-use export rates that would significantly reduce rooftop solar economics.
- —
Broadband deployment obligations and pole attachment rate disputes: Disputes between rural electric cooperatives, IOU utilities, and broadband providers over pole attachment rates and make-ready cost allocation have increased before MoPSC, particularly as federal BEAD Program funding accelerates broadband buildout in unserved Missouri counties.
