Terralight-IndiGrid-EnerGrid
Terralight Solar Energy Tinwari Pvt Ltd (TSETPL), it is reliably learnt, is a company promoted by EnerGrid – a new investment platform co-promoted by IndiGrid Infrastructure Trust (IndiGrid), British International Investment (BII) and the Norwegian Climate Investment Fund (Norfund).
As discussed in tndindia.com’s story dated February 6, 2026, IndiGrid would henceforth be bidding for power transmission and BESS projects, under TBCB, through EnerGrid, and not by itself. EnerGrid is officially known as “Enerica Regrid Infra Pvt Ltd.”
EnerGrid, through its subsidiary “Enerica 1 Infra Pvt Ltd,” had acquired the ISTS-TBCB scheme housed under “Morena 1 SEZ Transmission Ltd,” on February 3, 2026.
Terralight Solar Energy Tinwari Pvt Ltd is a subsidiary of “Enerica 3 Infra Pvt Ltd,” in turn, a subsidiary of EnerGrid. It is further learnt that TSETPL is setting up a 5-MW(AC) plant in Rajasthan that will sell electricity generated to NTPC Vidyut Vyapar Nigam Ltd (NVVNL) under a 25-year power purchase agreement.
As per the agreement reached between the promoters of EnerGrid, all projects developed under the EnerGrid platform will be acquired by IndiGrid, one year after their respective scheduled commercial operation dates (SCOD).
