Generally revise energy laws

This bill revises Montana's energy laws to establish a competitive bidding process for constructing new electric transmission lines valued at $8 million or more. It directly affects incumbent electric utilities, which retain the right to own and maintain transmission lines in specific regions after approving projects through a federally registered planning authority. The legislation requires utilities to conduct open bidding for qualifying projects while allowing them to set reasonable construction standards and inspect work to ensure compliance. Additionally, the bill clarifies definitions for transmission lines and incumbent utilities, and mandates equal sharing of transmission lines connecting two separate utilities unless otherwise agreed upon.
