EXXONMOBIL on Thursday said it has started the construction of a new 84-megawatt cogeneration facility at its Singapore refinery's Jurong site.
The move will increase the energy efficiency of the refinery upon completion.
Cogeneration is the simultaneous production of electricity and steam from a single fuel source.
The company added that when the latest cogeneration facility is completed in 2017, it will have more than 440 megawatts of capacity in Singapore.
The unit adds to the existing 360-megawatt cogeneration capacity at ExxonMobil's integrated refining and petrochemical complex, which currently meets all of its internal power needs on Jurong Island.
