Seattle City Light is proposing a new rate policy for large data centers to ensure they bear their own infrastructure costs. This policy follows the Seattle City Council's enactment of a one-year moratorium on data centers using over 20 MVA, a decision spurred by significant public opposition. The proposed rate policy, part of a larger ordinance, will apply across City Light's service area.

Seattle City Light is advancing a new policy framework aimed at managing the surge in data center development driven by artificial intelligence, ensuring that large data centers cover their own energy and infrastructure costs. The proposed "New Large Data Center Load Policy" would move new large data centers from general service rates to a dedicated rate class, preventing costs from being passed on to existing residents and businesses. This policy is integrated into a broader rate ordinance scheduled for review by the City Council’s Parks and City Light Committee on June 17.

This initiative follows significant public backlash against potential large data center projects in Seattle. Mayor Wilson and the Seattle City Council reportedly received thousands of emails, with the majority of residents expressing opposition. In response to this public sentiment, the City Council has enacted a one-year moratorium, temporarily prohibiting the siting of data centers in Seattle that consume more than 20 MVA.

During this moratorium, the City Council plans to study the comprehensive impacts of large data centers on urban infrastructure, utilities, land use, public health, and the local economy. A parallel resolution mandates the Mayor's Office to collaborate with city departments on formulating policies and legislative measures to guide future data center development within Seattle. While the moratorium applies specifically to Seattle city limits, Seattle City Light's proposed new rate policy would extend its reach across its entire service area, encompassing not only Seattle but also portions of Burien, Tukwila, SeaTac, Shoreline, Lake Forest Park, Renton, Normandy Park, and unincorporated King County. This proactive approach aims to manage finite resources and protect community interests.
