The waiver of interstate transmission system (ISTS) charges for projects commissioned by June 30, 2025, has enthused commercial and industrial consumers to procure power from ISTS-connected solar projects. In March this year, the Central Electricity Regulatory Commission amended the CERC (Sharing of Inter-State Transmission Charges and Losses) Regulations, 2020, waiving ISTS charges for renewable energy and pumped hydroelectric projects beginning operations by June 30, 2025. The waiver of these charges lowers costs for developers translating to attractive tariffs for businesses procuring power from ISTS-connected open access solar projects.
