MO HB925

Allows electrical corporations to defer depreciation expense and return on "qualifying electric plant" investments and recover these costs through a regulatory asset account included in rate base over 35 years

Qualifying electric plant includes replacements or modernizations of obsolete transmission, distribution, and generation facilities; grid automation technologies; grid hardening against severe weather or earthquakes; and capital projects for regulatory compliance

Deferred amounts include carrying costs at the utility's weighted average cost of capital and remain subject to prudence review by the Public Service Commission

Caps the revenue requirement impact at 1% multiplied by the number of months since the last rate case, divided by 12; any regulatory asset balance exceeding this cap is not recoverable

Exempts large industrial customers (5 megawatts or more minimum billing demand) from paying costs associated with these regulatory assets
