Modifies provisions for electrical corporations

HB 963 modifies how electrical corporations calculate customer rates and plan for future energy needs. It allows utilities to include costs for unfinished natural gas power plants in their rate base (the assets used to set prices), but requires annual submissions showing how they will meet capacity needs for the next four years. The bill includes a sunset clause, ending this rule by December 31, 2035, unless extended, and mandates refunds with interest if costs are deemed imprudently spent. This directly affects utility companies, the Public Service Commission (which oversees utilities), and electricity ratepayers.
