Inter-state OA — opportunities and challenges

Inter-state transmission system (ISTS) open access (OA) renewable market is growing strongly on the back of multiple drivers including a waiver from ISTS charges together with decarbonisation pressure on corporates and streamlined transmission connectivity approval process. However, the ISTS route savings are viable only for projects commissioned by June 2026 (at least 75% ISTS charge waiver). Other challenges include lack of banking facility and inadequate transmission infrastructure.
