Singapore's electricity generation capacity increased from 12,179.1 MW in 2021 to 12,762.3 MW in 2022. This was largely due to increase in solar PV systems, Energy Storage System (ESS) and electricity import capacities.
In 2022, Combined Cycle Gas Turbine Co-Generation and Tri-Generation plants continued to account for the largest share of the total generation capacity at 82.2% (or 10,491.4 MW). The remainder comprised Steam Turbines (6.0% or 763.6 MW), Solar PVs (5.0% or 634.3 MWac), Waste-to-Energy (3.1% or 393 MW), new energy technologies such as Battery ESS (1.6% or 200 MW), and Electricity Imports (0.8% or 100 MW).
As of Jun 2023, the installed capacity of Solar PV Systems increased further to 773.9 MW.
