MO: Utilities ordered to address solar, DERs, EVs, microgrids, TOU rates


The Missouri Public Service Commission has established a list of special contemporary issues that major electric utilities must address in their IRP filings or annual IRP update reports.

The issues that the state‚Äôs four major investor-owned utilities — Ameren, KCP&L, KCP&L GMO and Empire District Electric — must address include:

  • Evaluating the potential demand and energy load associated with EVs in their service territory.
  • Reviewing the options available to provide customer financing for energy efficiency.
  • Discussing plans to expand DG deployment.
  • Describing and documenting the roles which energy storage and conservation voltage reductions could play in system planning, particularly regarding DSM and DERs.
  • Evaluating the need to upgrade and enhance delivery infrastructure in order to ensure and advance system resiliency, reliability and sustainability.
  • Describing and documenting how investments in grid modernization, DSM, and renewables will ensure that the public interest is adequately served and that other state policy objectives are met.
  • Describing and documenting how standby rates, tariffs and interconnection standards facilitate the development of customer-owned DG resources and microgrids.
  • Reviewing plans to make TOU rates available to all customers.
  • Analyzing and documenting the future capital and operating costs faced by each coal-fired generator in order to comply with environmental standards.
