Sembcorp, HG Infra secure 900 MWh of tendered Indian battery capacity

Sembcorp has been awarded a 150 MW solar project and 300 MWh battery energy storage system (BESS) in a solar-plus-storage tender held by utility Satluj Jal Vidyut Nigam Ltd (SJVN), and H.G. Infra Engineering has secured a 300 MW/600 MWh BESS from a tender held by Gujarat Urja Vikas Nigam Ltd (GUVNL).

The Green Infra business of Sembcorp Industries has received a letter of award from public hydropower utility SJVN for a 150 MW solar project with a 300 MWh BESS.

This build-own-operate project is part of SJVN’s tender for 1.2 GW of inter state transmission system-connected solar projects that must be accompanied by 600 MW/2.4 GWh of BESS capacity.

Subject to the execution of a 25-year power purchase agreement (PPA) with SJVN, the project, upon completion, will supply solar power and support peak electricity demand for four hours daily through the BESS.

Commercial operations are expected to begin within 24 months from the date of signing the PPA.

“The project will be funded through a mixture of internal funds and debt,” stated Sembcorp. “This is Sembcorp’s second solar-energy storage hybrid project in India, increasing Sembcorp’s gross renewables capacity in India to 6.3 GW. Globally, Sembcorp’s total renewables portfolio has reached 17.7 GW, including acquisitions pending completion.”

H.G. Infra Engineering Ltd has announced that it has received a Letter of Intent from electric utility GUVNL for the development of a 300 MW/600 MWh standalone BESS in Gujarat. The project was awarded under GUVNL’s Phase VI auction for 500 MW/1 GWh of BESS capacity through a tariff-based competitive bidding process.

The project has a completion timeline of 24 months. The tariff is set at INR 285,600 ($3,336) per megawatt, with a contract duration of 12 years. The total project cost is estimated to be around INR 6.7 billion, plus taxes. Commissioning is scheduled by October 27.

This latest development follows H.G. Infra Engineering’s earlier success in securing a battery energy storage purchase agreement with GUVNL for a 250 MW/500 MWh BESS project, awarded under GUVNL’s Phase IV tender. That project is supported by the viability gap funding scheme, which supplies central government cash to help infrastructure projects be economically viable.

Opinion & Analysis

Falling li-ion battery prices mirror solar photovoltaics trends: Is there a role for second-life batteries before recycling? Lithium-ion batteries are everywhere, powering everything from consumer electronics to electric vehicles, residential PV storage systems, and, more recently, mitigating curtailment in large-scale wind and solar power plants. EVs are driving large-scale demand for Li-ion batteries which will result in substantial volumes of spent batteries in the near future. This scenario highlights the potential for repurposing EV batteries for second-life stationary applications, which could maximise their value before recycling. However, to fully realise this opportunity, several economic, technical, and regulatory challenges must be addressed and resolved.

Opinion & Analysis

Battery storage on a capacity market In Germany – but not only there – there is a heated debate about the pros and cons of a capacity market. The German Renewable Energy Association is against it, and recently the German New Energy Industry Association, the DIHK and the EEX energy exchange have also taken a clear stance: Germany does not need a “power plant subsidy program.” In this article, four experts explain why battery storage can also play an important role in a capacity market and make recommendations on how the design of the market can help avoid mismanagement, wrong incentives and unnecessary costs.
