Washington State debates data center growth; Seattle enacts moratorium and policy framework
Washington state is experiencing significant data center growth, prompting regulatory responses. Seattle has enacted a one-year moratorium on new data centers to conduct an impact study and adopted a policy framework to analyze their effects on utilities and land use.
Washington state is experiencing record data center growth, with CBRE reporting the second consecutive year of record leasing. This growth has sparked a debate over its economic benefits, such as jobs and tax revenue, versus concerns regarding power and water usage.
In response, Seattle's City Council passed two significant measures. Council Bill 121214 imposes a one-year moratorium on new data centers to allow for an impact study. Additionally, Resolution 32204 establishes a "strict policy framework" guiding Seattle departments and the Mayor's Office to analyze data centers' effects on the city's electrical grid, water consumption, utility rates, land use, local employment, and public health.
Beyond Seattle, the Washington State House passed House Bill 2515, which aimed to mandate electric utilities to develop policies for high-energy-use facilities and promote renewable energy. However, this bill did not advance through the Senate. The article notes a common debate about data center impacts, citing ProtectingTaxPayers.org, which claims that concerns over water usage (0.6% of state consumption in 2025) and electricity usage (4.1% in 2025) might be overstated.
