The bill aims to address the growing demand for electricity from large energy use facilities, such as data centers, by ensuring that the costs and risks associated with the necessary investments in electrical infrastructure are borne by these consumers rather than residential and small commercial ratepayers. It introduces new legal provisions, including the requirement for the Washington Utilities and Transportation Commission and the Department of Commerce to develop model tariffs specifically for large energy use facilities by June 30, 2027. These tariffs must allocate costs equitably and mitigate risks to other electricity consumers. Additionally, the bill mandates that contracts for electricity service between utilities and large energy use facilities must be established by January 1, 2028, with specific terms regarding duration, payment obligations, and conditions to protect the public interest.

Furthermore, the bill includes provisions for ongoing oversight and reporting. The Department of Commerce is tasked with submitting a report every odd-numbered year, starting September 1, to review trends in electricity demand from large energy use facilities and their implications for the broader electricity market. This report aims to inform legislative recommendations while safeguarding proprietary information. The new sections added to chapter 19.29A RCW also establish definitions and clarify the responsibilities of utilities in serving large energy use facilities, ensuring that the regulatory framework adapts to the evolving energy landscape.
