Addressing emerging large energy use facilities.

SB 6171 regulates large data centers (defined as facilities with ≥20 megawatts of energy demand) by requiring transparency about their electricity, water, and refrigerant use, and mandating that they transition to 100% clean energy over time. The bill directly affects data centers, particularly those supporting artificial intelligence growth, which are projected to become the largest source of new electricity demand in the Pacific Northwest. Key provisions include setting policy priorities for energy affordability, grid reliability, and environmental protection, while ensuring these facilities disclose resource consumption data to the public. The legislation aims to balance the industry’s economic benefits with safeguards for consumers and communities.
