Allows electrical corporations to charge for services based on the costs of certain construction work in progress

HB 1626 allows Missouri electrical utilities to include the costs of constructing new clean baseload power plants (like nuclear facilities) in their rate base during construction, enabling them to recover these costs through customer rates before the plant is fully operational. The Public Service Commission must approve the amount included, limiting it to the project’s estimated cost and actual spending during construction. If the project is delayed or costs were incurred imprudently, utilities must refund overcharges with interest. This provision applies only to new plants not operational by August 28, 2026, and expires on December 31, 2036, unless extended.
