The bill seeks to enhance the deployment of low carbon thermal energy networks in Washington State by amending the Revised Code of Washington (RCW) to include new definitions and regulations for thermal energy companies. Key insertions include the definitions of "thermal energy company" and "thermal energy networks," which facilitate utility-scale distribution of thermal energy without combustion, except in emergencies. The bill exempts thermal energy companies operating before July 1, 2025, from commission regulation unless they choose to opt-in, and outlines conditions for remaining exempt based on customer thresholds. It also clarifies that combined heat and power facilities are similarly exempt unless they opt-in for regulation.

Additionally, the bill aligns thermal energy companies with existing regulations for gas, electrical, wastewater, and water companies, mandating just and reasonable charges, budget billing for low-income customers, and guidelines for service reconnection during heat alerts. It introduces regulatory measures such as the appointment of inspectors for thermal energy meters and requires companies to maintain testing facilities for meter accuracy. The bill also emphasizes the integration of thermal energy networks into existing utility operations, allowing for discounted rates and requiring electric utilities to assess their efficiency. Overall, the legislation aims to create a comprehensive regulatory framework that supports the growth of sustainable thermal energy solutions while ensuring consumer protections.
