Two Seconds to Stability: Inside Singapore’s Battery Breakthrough
On 28 September 2026, PacificLight Power broke ground on a 670 MW gas-fired power plant on Jurong Island. The headline number is the plant’s size—Singapore’s largest single-unit CCGT facility, capable of supplying 1.2 million four-room apartments annually. But the real innovation sits in the battery.
The 80 MW Battery That Thinks in Milliseconds
The plant will be equipped with an 80 MW lithium-ion battery energy storage system (BESS), allowing electricity to be stored during low-demand periods and released when needed. The system can respond within two seconds, balancing supply and demand and enhancing grid stability.
This matters because Singapore’s grid is changing. As solar deployment expands—now exceeding 2 GWp—intermittency becomes a real operational challenge. Clouds pass. Generation fluctuates. The integrated battery acts as a buffer, smoothing the transition between gas generation and solar input.
Hydrogen-Ready and Future-Proof
The plant will initially run on a fuel mix containing up to 30% hydrogen and natural gas, with plans to eventually operate entirely on hydrogen. The 1.2 billion SGD investment is not just about meeting today’s electricity demand—it is about building infrastructure that can decarbonise as hydrogen supply chains mature.
Singapore currently operates more than 20 gas-fired power plants. The power sector accounts for around 40% of the nation’s total emissions. The PacificLight plant represents a strategic bet: gas remains the backbone, but batteries and hydrogen provide the flexibility and decarbonisation pathway.
Jurong Island: Singapore’s Energy Laboratory
The choice of Jurong Island is deliberate. The island already hosts Singapore’s largest utility-scale energy storage system—a 200 MW BESS that serves as a rapid-response stabiliser for the grid. The new PacificLight plant adds another layer: generation, storage, and hydrogen readiness in a single integrated facility.
