Tata Power Delhi Distribution Limited (TPDDL), a discom under Tata Power, has invited bids for the supply of 250 MW of firm and dispatchable renewable energy (FDRE) integrated with energy storage systems (ESS). The projects are to be developed on a build-own-operate basis. Energy sources may include solar, wind, or other renewable forms, but all projects must incorporate ESS that is exclusively charged by renewable energy. The bid capacity is fixed at 50 MW, although a relaxed minimum of 25 MW is permitted for projects located in the northeastern states or within Maharashtra’s intrastate transmission system.
According to the tender guidelines, the bidders are required to submit a money deposit of Rs 928,000 per MW for solar projects, Rs 1.26 million per MW for wind or other renewable energy projects, and Rs 366,000 per MWh for the ESS component. The bidders may propose their preferred technologies during submission and have the flexibility to confirm or alter the ESS technology later. Selected bidders will be required to enter into a 25-year power purchase agreement. The deadline for bid submission is June 6, 2025.
For projects located outside Maharashtra, the tender reportedly requires quoting inter-state transmission system charges of Rs 0.11 per kWh and transmission losses of Rs 0.22 per kWh. These additional costs will be considered only for bid evaluation purposes to ensure parity with intra-state projects. Projects connected to the Maharashtra state transmission utility system shall be exempt from these costs, given that transmission charges and losses are regarded as non-applicable. This exemption applies since TPDDL is recognised as a long-term transmission system user in Maharashtra. Furthermore, according to the eligibility criteria, a minimum net worth of Rs 12.26 million per MW of quoted capacity is also mandated, based on the last date of the previous financial year or at least seven days before the submission deadline.
