ISTS Waiver
To promote the development of renewables in RE-rich states and encourage inter-state procurement of renewables, the central government allowed waiver of ISTS charges and losses for solar and wind projects in 2016. Through various subsequent orders, the Ministry of Power (MoP) extended the deadline of ISTS waiver for some solar and wind project categories commissioned till 30th June, 2025. Recently, the ambit of the waiver has been widened for green hydrogen, large hydro plants, pumped storage hydro (PSH) and battery storage (BESS). We have tracked the several amendments and evolution of the ISTS waiver framework since 2016 below.
