Establish the Montana data center development act

This bill establishes the Montana Data Center Development Act to clarify rules for large electricity customers, primarily affecting data centers and other major energy users requiring over 5,000 kilowatts of demand. It prohibits the Public Service Commission from blocking regulated utilities from serving new large customers (like data centers) and clarifies that utilities must demonstrate long-term service won't harm other customers before providing power. The bill amends Montana law to ensure data center development isn't hindered by regulatory uncertainty, while maintaining the Commission's role in setting tariffs and oversight. It directly impacts how utilities serve large commercial and industrial customers seeking reliable, affordable power.
