Committee hears HB 40 to require transmission owners to evaluate grid‑enhancing technologies
HB 40 would require utilities to evaluate advanced transmission technologies (ATTs) and high‑performance conductors to reduce congestion and potential new transmission construction; supporters said ATTs can unlock ~20% more capacity and save ratepayers; a resident raised EMF/health concerns.
