IA HF2283

Public utilities and transmission companies owning or operating electric transmission lines in Iowa must submit feasibility studies to the Iowa Utilities Commission by January 1, 2027, and every three years thereafter

Studies must evaluate grid-enhancing technologies (dynamic line rating systems, power flow control systems, topology optimization) and identify transmission lines suitable for reconductoring with advanced conductors

Projects must address specific purposes including increasing transmission capacity, reducing congestion, connecting renewable resources, improving reliability, reducing land impacts from new transmission lines, and serving increased customer load

Advanced conductors are defined as having at least 10% lower direct current electrical resistance than existing conductors of similar diameter

Municipal utilities, cooperative electric associations, and companies owning transmission lines serving single customers or interconnecting single generating facilities are exempt from these requirements
