MO SB321

Prohibits electrical corporations from charging ratepayers for construction-in-progress costs or other costs associated with owning, operating, maintaining, or financing property before it is fully operational.

Requires electrical corporations seeking an early site permit from the U.S. Nuclear Regulatory Commission to submit monitoring reports to the Missouri Public Service Commission every six months documenting work completed, expenditures, and anticipated costs.

Allows electrical corporations that obtain an early site permit and comply with reporting requirements to recover prudently incurred costs up to $45 million through ratepayers over a period not to exceed 20 years, plus interest at the commission-approved return on rate base.

Requires the commission to credit ratepayers if an electrical corporation sells or transfers its interest in the permit or receives reimbursement, with credits including interest at the short-term borrowing rate.

Mandates a commission proceeding to determine if an electrical corporation acted imprudently if it fails to obtain a combined license or commence construction by the time the early site permit expires, with potential credits to ratepayers over 5-10 years if imprudence is found.
