Modifies provisions for electrical corporations

HB 853 modifies rules for electrical corporations by prohibiting them from charging customers for costs related to construction in progress (CIP) before facilities are operational. It permits corporations to include CIP costs in rate base under strict limits - approved by the commission, tied to actual project costs and timelines - and requires refunds with interest if costs were imprudently incurred. The bill also mandates annual capacity planning reports showing how corporations will meet future energy needs, with penalties for insufficient capacity due to imprudent decisions. The key provisions expire on December 31, 2035, unless extended by the commission after a 2035 hearing.
