Sembcorp unveils energy storage and solar projects on Jurong Island

These initiatives support Singapore’s push for a more resilient grid and 2030 green plan.

Sembcorp Industries is working on two clean energy projects that boost energy storage and solar power capacity on Jurong Island.

In a statement, Sembcorp said it has piloted a battery stacking solution on land at its existing Jurong Island energy storage system (ESS) facility. This is the first vertical expansion of an operational ESS on the same land area.

The company’s ESS capacity has since increased from 285 megawatt-hours (MWh) to 326MWh.

Following this development, Sembcorp said it is looking into deploying battery stacking across other sections of its Jurong Island ESS. The company will also partner the Energy Market Authority (EMA) to assess the ESS’s ability to provide inertia which helps maintain grid stability by slowing down sudden changes in electricity frequency during disruptions.

“Our collaboration with Sembcorp will allow us to test and understand these new BESS capabilities better. The knowledge and experience gained will help EMA plan for a grid that is cleaner, smarter and more resilient,” said Puah Kok Keong, chief executive of EMA.

Sembcorp also announced the 118 megawatt-peak Sembcorp Jurong Island Solar Farm, Singapore’s largest ground-mounted solar project to date. The project spans six interim vacant land parcels in an industrial zone and has the capacity to generate power for approximately 33,200 four-room HDB flats annually.

“These initiatives demonstrate our ability to integrate and scale clean energy generation and storage technologies, reinforcing a resilient and future-ready energy ecosystem,” said Koh Chiap Khiong, President & CEO, Gas and Related Services, and CEO, Singapore, Sembcorp Industries.
