Modifies provisions for the public service commission

HB 560 regulates how utility companies (like electricity and gas providers) can offer heating/ventilating/air conditioning (HVAC) services through new rules. It prohibits utilities from using regulated assets (like vehicles or tools paid for by ratepayers) for HVAC work without reimbursing the utility, requires clear disclaimers when using utility names for HVAC services, and mandates separate financial records for HVAC operations. The bill also sets civil penalties of up to $12,500 per violation for non-compliance and allows the public service commission to investigate and enforce these rules. It includes a grandfather clause permitting utilities to continue pre-1998 HVAC services but prohibits subsidizing HVAC through regulated utility rates. The law applies to all utilities and their contractors offering HVAC services in Missouri.
