Generally revise digital asset mining and data center ratemaking laws

This bill requires data centers and digital asset mining businesses in Montana to report their electricity usage to the state commission and a legislative committee. It defines data centers as facilities primarily occupied by computing equipment and digital asset mining as using electricity to secure blockchain networks, with specific thresholds for what constitutes a business versus home mining. The law mandates that these facilities submit annual reports detailing their past and projected electricity consumption by March 1 of each year. Additionally, the bill prohibits the commission from creating electricity rate classifications for these users that would be unduly discriminatory compared to similar industrial uses. The changes will take effect on March 1, 2026.
