Energy

HB 2515 requires data centers with 20+ megawatt demand - defined as "emerging large energy use facilities" - to transition to 100% clean energy over time and publicly disclose their electricity, water, and refrigerant usage. The bill aims to protect energy affordability, grid reliability, and environmental health by mandating transparency and clean energy standards for these rapidly growing facilities. It amends existing energy laws to establish new definitions and oversight for data centers, which are projected to become the largest source of electricity demand growth in the Pacific Northwest. The policy applies directly to data center operators, with requirements phased in to align with industry innovation while safeguarding public interests.

HB 1912 establishes a system for tracking and reporting sales of fuel used for agricultural purposes, which are exempt from the state's Climate Commitment Act. Fuel sellers, including retail stations and suppliers, can register with the Department of Ecology to track and report these exempt sales. Registered sellers must make exempt fuel available at a differential rate or credit purchasers to reflect the absence of associated compliance costs under the climate act. This ensures the agricultural exemption is properly applied and monitored, affecting fuel sellers, suppliers, and agricultural users starting January 1, 2026.
