Solar Energy Corporation of India's 1,000 MWh energy storage space tender winner revealed

• Bidding process took place last week in a reverse auction to contract for 500MW/1,000 MWh of standalone battery energy storage space capacity with the Solar Energy Corporation of India (SECI).

Various news outlets reported on Friday (26 August) that JSW Renew Energy Five, an unique function vehicle developed by the renewable energy subsidiary of power producer JSW Energy had sent a winning bid.

SECI tendered for two 250MW BESS projects to be built at the same place, attaching to India's Inter-State Transmission System by means of a substation at Fatehgarh in the state of Uttar Pradesh.

Bidding process proceeded for greater than 10 hours, with bids from significant Indian business like ReNew Solar Power, NTPC Renewable Energy and Azure Power, as well as international entities such as energy trading investment company Hartree Partners Singapore.

According to a bidding portal seen by Energy-Storage. news, JSW won with a bid of INR1,083,500 (US$ 13,590) per MW. With a wide spread of bids seen, this was 111% lower than the lowest-ranked bid out of 8 entrances in total amount.

Formally released by SECI in April after a number of months of expectancy from the market, the pilot tender is designed to be replicable for other tender programmes and also help to inform exactly how they will certainly be carried out.

A total amount of 4,000 MWh of pilot tenders for standalone energy storage space are anticipated to be introduced in overall by the federal government of India. This is in addition to activities at state level, such as the present 500MW tender for renewables with storage space being run by the power board in the state of Gujarat, to offer one example.

Energy-Storage. news has connected to SECI for official verification of the tender outcome as well as more comments.

At our webinar on India with Clean Horizon, which occurred in June, Dr Bharath Reddy, SECI additional general supervisor, discussed that the pilot deployments' applications will certainly include energy arbitrage, aiding utilities to shift surplus energy from off-peak times to be made use of on the grid throughout peaks and also can help in reducing curtailment of renewable energy.

SECI will also be "scheduling some capacity to the grid operator" so that the use of battery storage for ancillary solutions like frequency feedback will certainly be trialled. Yet, India has actually not presented widespread programmes for supplementary solutions in which batteries are eligible to participate, but this is recognized to be altering.

Designers will certainly also have the ability to offer several of their battery storage capacity outdoors market, Dr Reddy said. SECI will authorize contracts to make use of 60% of project capacity via a battery energy storage space purchase arrangement (BESPA), leaving 40% of BESS capacity for the programmer to monetise as ideal.

Efficiency standards consisted of 95% minimum schedule of source on an annual basis, factoring in annual degradation anticipated.

Project proprietors must preserve 85% or greater roundtrip performance of their asset. Charging and releasing timetables will certainly be established by the off-taker, with a 'resting duration' of one hr with BESS assets to be used for approximately two complete charge-discharge cycles each day. Non-availability and also lower-than-promised effectiveness will certainly be punished.
