Modifies provisions for the construction of electric transmission facilities

HB 221 requires electricity companies to obtain commission approval before constructing new electric transmission facilities (defined as lines designed for 100kV or higher). It mandates that such facilities be designed to use existing infrastructure where possible, include multi-circuit configurations, and undergo competitive bidding for major construction components. The bill applies specifically to companies building major transmission lines connecting to regional grid operators, excluding small-scale projects under 1 megawatt. The commission must review applications based on public benefit, reliability, and economic impact, with approval lapsing if construction doesn't begin within two years.
