Concerning business development.

HB 1245 requires large electric utilities (with over 25,000 customers) to develop comprehensive 10-year integrated resource plans. These plans must include detailed forecasts of customer demand, assessments of conservation and renewable energy options, transmission capacity needs, and strategies for meeting clean energy goals. The bill specifically mandates evaluating impacts of zero-emission vehicles, incorporating data from transportation electrification plans, and ensuring plans prioritize "lowest reasonable cost" while maintaining grid reliability. It directly affects utilities serving over 25,000 customers, requiring them to update these plans every four years with annual progress reports. The bill amends existing energy planning laws (RCW 19.280.030) but does not create new funding or direct cost obligations.
