Commerce bill would extend program timelines, add energy‑security authority and align heat‑pump rules with federal programs

House File 4559 would give Commerce authority to maintain a statewide energy-security plan, extend timelines for electric-school-bus and solar-on-public-buildings programs, and align the state heat-pump program with anticipated federal requirements to allow incentive stacking and renter eligibility. Committee discussion focused on timelines, program mechanics and fraud-prevention; bill laid over.
