"Project Catalyst" Data Center (Alcove Development, Osawatomie)
Alcove Development. Filed, 500 MW
Lawrence based Alcove Development signed a three year predevelopment agreement with Osawatomie for what it calls Project Catalyst, a data center campus that has grown from an initial 115 acre plan to roughly 283 acres near the Osawatomie State Hospital. The Kansas Department for Aging and Disability Services said in September 2026 that the psychiatric hospital will stay open and that it is working with the city and developer on noise and lighting mitigation, while the project's water request has dropped from 1 million to 800,000 gallons a day and its request for city supplied power has dropped from 50 to 150 megawatts down to zero. The earlier plan for industrial revenue bonds and a 50 percent, ten year property tax abatement has reportedly been removed, and the city and planning commission are still waiting on environmental and impact studies before reviewing a formal application.

What it would mean nearby
The cooling design has not been reported. If it uses evaporative cooling, a 500 MW facility would draw roughly 1.6 million to 5.7 million gallons of water a day, about what 18,200 households use.
