MO SB459

Beginning August 28, 2013, the Public Service Commission must use only the revenue allocation method in rate cases involving electric corporations providing electric service.

The commission may phase in large revenue increases over a reasonable number of years if primarily due to an unusually large increase in the corporation's rate base, while allowing full recovery with just and reasonable adjustments for deferred revenue.

The commission may approve multiple tariff schedules to take effect at different times to implement a phased-in rate increase.

For wholly owned subsidiaries of public utility holding companies, the commission may phase in unusually large revenue increases primarily due to increased expenses from Federal Energy Regulatory Commission regulation of generating facilities owned by related subsidiaries, including reasonable financing costs.
