Sembcorp Industries, through its wholly-owned subsidiary Sembcorp Green Infra Private Limited (SGIPL), has been awarded a 150 MW solar power project integrated with a 300 MWh Battery Energy Storage System (BESS) by SJVN Limited. This project is part of SJVN’s 1.2 GW tender for Inter-State Transmission System (ISTS)-connected solar projects, which includes a total of 600 MW/2.4 GWh of battery storage capacity.
The project will be developed on a build-own-operate basis, with commercial operations expected to commence within 24 months from the signing of a 25-year Power Purchase Agreement (PPA) with SJVN. Upon completion, it will supply solar power and support peak electricity demand for four hours daily through the BESS.
This marks Sembcorp’s second solar-plus-storage hybrid project in India, increasing its gross renewable energy capacity in the country to 6.3 GW. Globally, Sembcorp’s total renewables portfolio now stands at 17.7 GW, including acquisitions pending completion.
The project will be funded through a mix of internal funds and debt. It is not expected to have a material impact on Sembcorp’s earnings per share or net tangible assets per share for the financial year ending December 31, 2025.
