The Senoko Power Station is the largest power station in Singapore. It is located in Senoko, Sembawang and was commissioned in 1976. It is owned by Senoko Energy Pte Ltd, formerly known as Senoko Power Ltd.
The Steam Plant Stage I, which was completed in 1976, comprised three steam thermal plants with 120 MW of capacity each.
The Steam Plant Stage II, which was completed in 1979, comprised three steam thermal plants with 250 MW of capacity each.
The Steam Plant Stage III which was completed in 1983 comprises another two steam thermal plants with 250 MW of capacity each. In 1992, Stage III 250 MW boilers were modified with gas burners to enable it to fire both Natural Gas and Fuel Oil.
The combined cycle plants include combined cycle plants 1 and 2, combined cycle plants 3 to 5 and combined cycle plants 6 and 7.
The Gas Plant Stage I was an open cycle plant with 4 open cycle gas turbines with 131 MW capacity when commissioned in 1991. In 1994, the 4 open cycle gas turbines were converted into two blocks of combined cycle plants with 425 MW of capacity each and renamed CCP 1 and 2. In 2010, Gas Turbine GT22 of CCP 2 was upgraded with new vanes and blades for its stage 1 and 2
The combined cycle plants 3 to 5 were completed and fully operational by 2004 with 365 MW of capacity each, which involved the repowering of the Stage I oil-fired steam thermal plant.
The combined cycle plants 6 and 7 were completed and commissioned by 2012 with 431 MW of capacity each, which involved the repowering of the Stage II oil-fired steam thermal plant.
In its early years, the plant used crude oil as fuel to power its turbines; however, this was replaced by natural gas piped from Terengganu on the east coast of Peninsular Malaysia after 1992. Oil, however, is still used as a back-up.

CCP 1 & 2
In 1992, a fire broke out at one of its plants resulting in a major power outage in the island.
Based on a mutual agreement between Malaysia and Singapore on electricity, the plant is linked by a submarine cable to the Sultan Iskandar Power Station in Pasir Gudang, Johor. In the event of a power outage in Peninsular Malaysia, the plant would supply electricity to the Johor plant. Likewise, if there is a power outage in Singapore, the Johor plant would supply electricity to Senoko.
