Sembcorp expands Jurong Island solar capacity and battery storage projects

• Sembcorp commissioned a 118-MWp solar project and expanded a 326-MWh battery on Jurong Island, bolstering clean power and flexibility for Singapore’s industrial hub.

Sembcorp has finalized two major clean-energy additions on Singapore’s Jurong Island: a 118-MWp solar farm and an expanded 326-MWh battery energy storage system (BESS). Together they strengthen the power system serving one of Asia’s largest petrochemical and industrial clusters, pairing daytime renewable generation with multi-hour flexibility to support evening and contingency needs.

The new 118-MWp array follows a bankable blueprint—high-efficiency PV modules on optimized mounting, string inverters for granular fault isolation, and a plant controller that delivers reactive power, ride-through and rapid curtailment aligned with local codes. On an island where land is scarce, rooftops, reservoirs and integrated industrial sites make solar siting a design exercise as much as an engineering one; Sembcorp’s portfolio experience shows in compact layouts and glare-mitigation planning around sensitive operations.

The 326-MWh BESS is the other half of the equation. Co-located storage soaks up solar surpluses and discharges into evening peaks while providing fast frequency response and voltage control in seconds. Grid-forming inverters enable synthetic inertia—valuable in a system with high shares of inverter-based resources—and a supervisory controller co-optimizes energy arbitrage with reserve products, keeping state of charge available for high-value events.

Jurong Island’s industrial loads demand precision. The combined system can shave demand charges, reduce reliance on gas-fired peakers, and improve power quality for sensitive processes. It also supports Singapore’s broader strategy to scale renewables and flexibility without compromising reliability, integrating neatly with demand response, interconnectors and efficiency programs.

Community and environmental measures—noise and traffic management during construction, drainage sized for tropical downpours, and responsible end-of-life plans—are standard. Post-COD, disciplined O&M (thermal inspections, cell balancing, firmware updates) will underpin availability and safety across the battery’s life.

In dense, space-constrained Singapore, the Jurong Island build demonstrates how to squeeze more value from each installed megawatt—stacking solar with storage to turn variable energy into dependable capacity where industry needs it most.
