Indiana Utility Regulatory Commission Begins Study on Advanced Transmission Technologies

On June 2, The Pew Charitable Trusts submitted comments to the Indiana Utility Regulatory Commission (IURC) on its study of the potential use and deployment of advanced transmission technologies (ATTs) by public utilities; the study is required under enrolled Senate bill 422, which passed the state Legislature in 2025 with unanimous support. Pew’s comments urged Indiana officials to provide clear standards for how utilities should evaluate the benefits of deploying ATTs and highlighted examples of two possible frameworks that the IURC could use to assess these benefits: the Indiana Office of Energy Development’s five policy pillars and the seven benefits outlined in the Federal Energy Regulatory Commission’s orders 1920 and 1920-A.

ATTs are a family of small devices and software that can be quickly installed on existing energy infrastructure and provide near-term opportunities to strengthen the power grid by unlocking additional capacity on transmission lines, reducing costs for consumers, and improving system performance and resilience. With energy demand rising, ATTs can play an important role in modernizing Indiana’s electric grid.
