PacificLight Power has started construction on a 670 MW combined cycle gas turbine plant on Jurong Island, Singapore's first gas plant to include an 80 MW battery storage system. The $1.2 billion facility, due online in 2029, will be the largest single-unit CCGT in the country and boost PacificLight's capacity by 70%. The battery is designed to respond within two seconds, supporting grid stability as solar deployment grows. The plant is hydrogen-ready, able to burn a 30% hydrogen blend initially, with plans to reach 100% hydrogen as costs and infrastructure improve. Singapore's peak electricity demand is forecast to grow 2.4% to 6.5% annually over the next decade, driven by AI, advanced manufacturing, and electrification. The project also aligns with the government's creation of a new Ministry of Energy, Trade and Industry in October.

Singapore's first gas plant with battery storage. Interesting approach, using batteries to allow a larger turbine without grid instability. 670 MW CCGT plus 80 MW storage, hydrogen-ready. Worth watching how the hydrogen transition plays out.

80 MW battery responding in two seconds, that's fast. But what's the actual capacity factor impact? Pairing gas with storage makes sense for ramping, but I'd like to see the dispatch strategy. Also, the cost of 1.2 billion for 670 MW seems steep, but that's Singapore.

Hydrogen-ready is nice, but green hydrogen is expensive and infrastructure isn't there. PacificLight admits it. So realistically it's a gas plant for now. The battery is the more immediate decarbonization play, helping solar integration.

Interesting that MTI becomes METI, signaling energy's importance. This plant is part of a broader trend of hydrogen-ready gas. Policy should ensure these plants are actually built to convert, not just a label. Also, peak demand projections are wide, 9.9 to 13 GW by 2031.

So they're building more gas capacity despite climate goals. But with battery storage and hydrogen compatibility, it's a bridge. The question is whether the hydrogen will ever materialize at scale. For now, it's a fossil plant with a battery.
