SJVN announces auction results for developing 1,200 MW of ISTS connected solar power projects

The project is integrated with 600 MW/2,400 MWh energy storage systems (ESS). The tender allowed bidders flexibility in choosing project sizes, with a minimum bid of 50 MW and a maximum cap of 600 MW. 

SJVN Limited has announced the results of its auction for developing 1,200 MW of interstate transmission system (ISTS)-connected solar power projects integrated with 600 MW/2,400 MWh energy storage systems (ESS). The auction witnessed active participation from several major renewable energy developers, with competitive tariffs being discovered.

SAEL Industries, Jindal India Renewable Energy, Sembcorp Green and JBM Renewables each won capacities of 150 MW, 300 MW, 150 MW, and 150 MW respectively, all quoting a tariff of ₹3.32 per kWh. Fastnote Biofuels (Hindustan Power) was awarded 100 MW at a slightly higher tariff of ₹3.33 per kWh. Reliance NU Energies (a part of Reliance Power) secured 350 MW out of its quoted 600 MW at ₹3.33 per kWh using the bucket-filling method. This auction, initially floated in September 2024, marks a significant step toward enhancing India’s renewable energy portfolio with integrated storage solutions.

The tender allowed bidders flexibility in choosing project sizes, with a minimum bid of 50 MW and a maximum cap of 600 MW. Eligible projects included those under construction, yet to be commissioned, or commissioned but supplying power on a short-term merchant basis. However, projects already accepted under other state or central schemes or those with power purchase agreements (PPAs) in place with designated beneficiaries were excluded.

A key feature of the tender was its technological openness. Developers were permitted to use crystalline silicon, thin-film, or concentrated photovoltaic modules, with or without trackers. Moreover, the tender mandated the use of commercially established and operational technologies to reduce execution risk and ensure timely completion.

This auction highlights the growing momentum of solar-plus-storage projects in India, promoting a stable and flexible renewable energy supply and aiding in grid management through integrated ESS components.
