House Joint Resolution No. 46, introduced by Representatives T. Millett and G. Kmetz, calls for an interim study to assess the potential impacts of data centers on Montana's economy and its electric generation, distribution, and transmission systems. The resolution highlights the growing interest from national companies in establishing data centers in Montana, which could lead to significant economic benefits, including job creation and increased tax revenue. However, it also raises concerns about the substantial energy demands of these facilities, which could strain the state's electric grid and affect the affordability and reliability of electricity for existing customers.

The resolution requests that the Legislative Council designate an appropriate interim committee to investigate various aspects related to data centers, including their impact on energy supply, potential rate increases for consumers, and the classification of data centers as a distinct customer class. The study will also explore the implications for Montana's water resources and overall economic landscape. The findings and recommendations from this study are to be presented to the 70th Legislature by September 15, 2026, ensuring that policymakers have the necessary information to make informed decisions regarding the future of data centers in the state.
