Question 1:

What is PowerSeraya’s power generation capacity?

PowerSeraya’s full licensed capacity is 3100MW and total installed capacity is 3240MW.

Question 2:

How is electricity transmitted to consumers and households?

The generator converts all the mechanical power from the Gas Turbine and the Steam Turbine into electrical energy. The electricity output from the generator is raised to a higher voltage through step-up transformers, for transmission through the networks. The electricity from the networks then reduces to a lower voltage through step-down transformers and is distributed to our homes, schools and workplaces.

Question 3:

How does PowerSeraya generate electricity?

PowerSeraya generates electricity through three types of power plants, namely:
* Steam.
* Open Cycle Gas Turbine.
* Combined Cycle
To produce electricity, power plants use various other forms of energy (heat, chemical or mechanical). Through this, they gather enough power to convert them to electricity.

Question 4:

How many power stations does PowerSeraya have?

PowerSeraya has two power stations – this station, which is called Pulau Seraya Power Station and Jurong Power Station which is located at Jurong Pier Road.

Question 5:

Can you tell me more about PowerSeraya’s history?

PowerSeraya’s plant on Jurong Island was built in 1986. It was Singapore’s first offshore power station with nine units of 250 MW oil-fired steam generating units and two units of 20 MW gas turbines and an installed capacity of 2290MW. To further strengthen our position as a top energy supplier, two units of 370MW Combined Cycle Gas Turbines were added boosting our installed capacity to 3240MW. With increasing competition and the trend towards using Combined Cycle Power Plant units to provide the baseload, PowerSeraya’s steam units were no longer efficient.

Thus, in 2003, PowerSeraya embarked on a full scale plan to convert three units of its conventional steam plants to run on Orimulsion; with the option to run on heavy fuel oil. This capital investment of $200 million is part of an integrated multi-fuel strategy allows us to maximise the operational efficiency of our generation units and lower portfolio costs.
