This bill establishes a new section in Iowa law focused on grid-enhancing technologies and reconductoring of electric transmission lines. It defines key terms such as capacity, congestion, dynamic line rating system, and grid-enhancing technology, which includes hardware and software aimed at improving the efficiency and reliability of the electrical grid. The bill mandates that public utilities and transmission companies operating in Iowa prepare and submit a feasibility study by January 1, 2027, and every three years thereafter. This study must assess the potential for implementing grid-enhancing technologies and identify opportunities for reconductoring with advanced conductors, providing detailed information on feasibility, costs, and implementation timelines.

The study is intended to identify projects that can achieve various objectives, including increasing transmission capacity, reducing congestion, enhancing the integration of renewable energy sources, and improving overall reliability. Notably, the bill exempts municipal utilities, cooperative electric associations, and entities that own transmission lines serving a single customer or generating facility from these requirements. Additionally, it allows utilities to utilize existing analyses from regional transmission organizations to fulfill the study requirements, ensuring a more efficient approach to meeting the bill's objectives.
