Requests an interim study of data centers' potential impacts on Montana's economy and electric generation, distribution, and transmission systems, with findings to be reported to the 70th Legislature

Two proposed data centers in Montana are estimated to consume up to 400 megawatts of electricity by 2030, equivalent to powering approximately 320,000 households for one year

Study must examine impacts on grid reliability and affordability for existing residential, commercial, and industrial customers, including potential rate increases from utility investments to serve data centers

Requires analysis of bonding requirements or other protections against stranded utility investments if data centers fail to materialize, close prematurely, or are abandoned

Study must also assess data center demands on ground and surface water resources, economic impacts on jobs and tax revenue, housing affordability, and whether the public service commission should classify data centers as a distinct customer class
