Singapore is carrying out a study aimed at trying to tweak the mix of different fuels, that will be used to generate electricity there in future.

The aim is to achieve not only competitively-priced electricity for Singapore’s industries and households, but also secure stable power supplies.

John Ng, CEO of PowerSeraya, one of Singapore’s biggest generating companies, said that the study’s focus on existing steam plants is because all the generating copanies have moved from using fuel oil-fired steam plants to more efficient combined cycle gas-turbine (CCGT) plants to produce electricity.

‘The gas-fired plants are economically superior from a cost-generation perspective,’ he said, adding that this ‘is why the steam plants have been marginalised’.

Because of the reliance on gas-fired plants, Singapore is currently building a $1.7bn LNG terminal to bring in liquefied natural gas from mid-2013 to supplement current piped gas supplies from Indonesia and Malaysia.

The EMA in late-2010 also said that it was prepared to look at other options like coal-fired plants and also electricity imports in the medium term.

PowerSeraya’s Mr Ng said that ‘Singapore is clearly trying to bring in as many economical ways of electricity supplies to try to reduce the price of electricity here. But it has also to balance this, as the higher the reserves margin, the safer power supplies will be’.

Singapore is actively exploring ways to diversify its energy portfolio to include clean energy sources, such as solar energy.

The Republic has sought membership to the International Renewable Energy Agency as part of its ongoing efforts to develop renewable energy.
