Capability

Power generation in Singapore

The gencos that convert imported natural gas into electricity through combined-cycle and cogeneration plants concentrated on Jurong Island and at Senoko. Buyers and the regulator read a genco on capacity (MW) and technology (CCGT, cogeneration), market share, ownership and hydrogen-readiness.

Power generation is the utility spine of Singapore's energy economy — the gencos that convert imported natural gas into electricity. Singapore's total licensed generation capacity was 13,261 MW as of the first half of 2025, and the system is almost entirely gas-fired: natural gas supplies about 93–94% of the fuel mix, delivered through combined-cycle and cogeneration plants concentrated on Jurong Island and at Senoko. The buyer/regulator reads a genco on capacity (MW) and technology (CCGT, cogeneration/CHP), market share, ownership, and increasingly hydrogen-readiness — the whole new build wave is designed to co-fire hydrogen. The market is a concentrated top three: Senoko Energy, Tuas Power and YTL PowerSeraya together held roughly half of it in the first half of 2025.

The field is a set of homegrown/Singapore-operating utilities, several now foreign-owned after Temasek's divestments. Senoko Energy is the largest at ~2,800 MW (50/50 Sembcorp/Marubeni); Tuas Power (~1,876 MW, China Huaneng-owned) and YTL PowerSeraya (~1,540 MW plus Jurong, YTL Power-owned) complete the big three. Keppel runs the ~1,340 MW Merlimau Cogen and the new hydrogen-ready 600 MW Sakra Cogen (in commercial operation from May 2026); Sembcorp runs the Sakra and Banyan cogen plants and half-owns Senoko; PacificLight Power (~815 MW, First Pacific/Meralco) won rights to a new ~670 MW hydrogen-ready plant; and Meranti Power is the EMA's own hydrogen-ready reserve genco (~682 MW). The structural story is decarbonisation via hydrogen-ready gas — Sakra Cogen, Meranti and PacificLight's new unit are all designed to co-fire up to 30% hydrogen. Lead with the gencos; several also carry LNG/gas and hydrogen slugs; dedup Sembcorp/Keppel against clean-energy.

  • Keppel

    An SGX-listed asset manager and operator whose infrastructure arm spans three clean-energy capabilities. In solar, Keppel Renewable Energy develops solar and cross-border clean-power, progressing an Indonesia-to-Singapore electricity import licence. In water, Keppel Seghers built and operates the 137,000 m3/day Keppel Marina East Desalination Plant and delivered the 162,800 m3/day Ulu Pandan NEWater upgrade. In waste, it runs the ~2,310 t/day Senoko and ~800 t/day Keppel Seghers Tuas waste-to-energy plants, together treating close to half of Singapore's incinerable waste.
