Data center boom strains Seattle utility's limited resources

Seattle City Light, the utility serving Seattle, Washington, is facing significant challenges in accommodating a proposed boom in data center development. Four unnamed companies have proposed building five large-scale data centers that would collectively require 369 megawatts of power, equating to approximately one-third of the city's current daily power consumption. The utility has expressed concerns that its existing staffing shortages and aging infrastructure are insufficient to handle this surge in demand, potentially compromising its ability to provide basic service to residents. The demand increase highlights a critical planning gap, especially as state and local officials advocate for rapid electrification. Seattle City Light is already experiencing a severe shortage of engineers and project managers necessary to manage infrastructure upgrades. The utility's vulnerability is compounded by recent financial missteps, including depleting savings to purchase expensive wholesale power due to poor drought planning, leading to higher rates for local customers. In response to these internal shortcomings and the strain on resources, Seattle City Light is rewriting its contracts for large-scale users. The new policy aims to mandate that private companies developing these data centers secure their own external power sources and cover the costs of any necessary infrastructure upgrades. City officials are firm that these expenses cannot be passed on to everyday ratepayers, who are already grappling with increased charges. The companies involved are expected to make a decision in the coming months on whether to proceed with their projects under these new, more restrictive terms or seek development opportunities where infrastructure and power sourcing are more readily available.
