MO SB909

Electrical corporations may place deferred depreciation expenses and return for qualifying electric plants into a regulatory asset account included in rate base calculations without offsets or reductions, recoverable over 35 years.

The regulatory asset account balance must be included in the next general rate proceeding, with the Public Service Commission retaining authority to review depreciation expenses for prudence.

Maximum average retail rate increases are capped at one percent multiplied by the number of completed months since rate base additions were last accounted for in the most recent rate proceeding, divided by twelve.

Customers with a minimum billing demand of five megawatts or more are exempted from rate increases caused by the regulatory asset account inclusion, with foregone revenues not collected from other customers.

Qualifying electric plants include environmental compliance projects, aging infrastructure replacements, generation facility modernizations, grid automation technologies, and facilities to harden the grid against severe weather or natural disasters.
