Winners announced for RUVNL’s 1.2 GW solar with storage auction

Results have been declared for Rajasthan Urja Vikas Nigam Limited’s (RUVNL’s) auction to develop 1,200 MW of solar projects with minimum six hours delivery from energy storage systems during peak demand. The projects can be developed anywhere in India. BluPine Energy and ACME have emerged as winners with respective quantities of 100 MW and 500 MW at a tariff of Rs 6.68 per kWh and Rs 6.69 per kWh, respectively. The auction was conducted by RUVNL in March this year, for only 600 MW and there has been no update on the remaining capacity as of yet.

The developer will be required to supply power everyday up to 3 MWh per 1 MW of the allotted capacity, especially during peak hours. Furthermore, the developer will be responsible for inter-state transmission system connection. The developers will be required to sign the power purchase agreement for a period of 25 years. The developer is also required to maintain an energy supply that achieves an annual output equivalent to a capacity utilisation factor (CUF) that is between 90 per cent and 120 per cent of the declared CUF value. Additionally, the solar modules should have a peak output wattage warranty which should be minimum, 90 per cent after 10 years and 80 per cent after 25 years.

In May 2023, Mahindra Susten, Sunfree Energy, Solarcraft Power India, Jakson, Shiva Corporation, Avaada Energy, and SJVN emerged as the winners for the RUVNL’s auction to supply 1 GW of power from state transmission utility connected solar power projects in the state.
