Data centers in Grant County, Washington: 6 projects mapped

Grant County, in the farm country of central Washington, draws data centers to Quincy with access to hydropower from the Columbia River. Microsoft has been building there for about twenty years and now runs its Columbia campus; Sabey and Vantage also operate data centers in Quincy, at 123 and 89 megawatts of power, along with CyrusOne's PNW1 and NTT Data's Quincy site. In nearby Moses Lake, Keel Infrastructure is building an 18-megawatt data center. Microsoft president Brad Smith said in January 2026, "we will add to the tax base that funds your local hospitals, your schools, your parks, your libraries," pointing to Quincy's high school as probably the nicest in the state. Former Quincy mayor Patty Martin, who has opposed the facilities since they first came to town, asked the other question: "What's the long-term impact for the short-term gain that we have?"

Power has become the constraint. Data centers used 37% of Grant County's power in 2025, and the public utility district, which receives about 63% of the electricity generated by the Wanapum and Priest Rapids dams, has long projected it would use its full share by 2026. In April 2025 Grant PUD said it would cap how much more power data centers could draw, because demand was outrunning its transmission lines. Its answer is a $260 million expansion to roughly double the power it can move into Quincy, including a new line from Wanapum Dam due by 2029.

That line is being fought over. Its most contested stretch crosses 112 parcels, including 34 homes; nine property owners argued the PUD had not followed the state's required negotiation and appraisal procedures. Jacque Rasmussen said the PUD's appraisal valued her property at $191,000, nearly $600,000 less than the estimate of an appraiser she hired. In August 2026 a Grant County Superior Court judge ruled the utility has the right to take the land regardless; how much owners are paid is still to be decided. Farmer Darrin Reynolds said the ruling sends a message that "we are the government and we'll steal it whenever we want."
