May 25, 2021 The waiver applies to inter-State transmission charges for 25 years. The National Solar Federation of India has written to the Ministry of Power seeking clarity on whether the long-term waiver of transmission charges will extend to solar and wind projects whose commissioning will get extended beyond June 2023 due to regulatory and government delays. “Many solar projects’ power supply agreements are yet to be signed and once signed, it is required to be approved by respective State electricity regulatory commissions. The whole process will take at least six months and it would not be possible for such projects to commission by June 30, 2023 in the current pandemic situation,” the industry group said in a May 20 letter to Power Secretary Alok Kumar.
