The Telangana Electricity Regulatory Commission (TGERC) has clarified that grid support charges (GSC) for co-located captive power projects (CPPs) must be calculated on the installed capacity after deducting the capacity supplied to third parties through open access and capacity committed under power purchase agreements (PPAs) with distribution licensees. The Commission ruled that the chargeable capacity must be determined by deducting these two categories from the installed capacity of the co-located captive power plant.
