An industry first project, KBPL operates under a unique regulatory framework notified by the Delhi Electricity Regulatory Commission (DERC). KBPL has been designed to integrate renewable energy at the distribution grid level, enable peak load management, strengthen grid stability, and support the provision of ancillary services – creating a scalable model for grid modernization and clean energy transition in India.
Ratle-Kiru ISTS scheme
In Q4FY25, IndiGrid added another greenfield project to its portfolio – Ratle Kiru Power Transmission Limited (RKPTL) – won through the TBCB route to establish an ISTS for evacuation of power from Ratle HEP (850 MW) & Kiru HEP (624 MW) on BOOT basis. The project is estimated to be completed over the next 24 months and will have annual transmission charges of Rs.1,952.32 million post commissioning.
Proactive participation in accretive greenfield transmission and BESS opportunities has consistently been part of IndiGrid’s growth strategy. With the win of RKPTL, the InvIT now has 6 greenfield projects in its portfolio, 4 ISTS and 2 BESS, an IndiGrid release noted.
Exciting year
According to Harsh Shah, Managing Director, IndiGrid, said, “It has been an exciting year for IndiGrid where we challenged ourselves to take on unprecedented goals. The successful commissioning of six transmission and BESS projects, addition of new greenfield projects, and the launch of EnerGrid showcases our commitment to building next-generation energy infrastructure for a greener, more resilient future.”
