(EnergyAsia, October 26 2010, Tuesday) — Germany’s Siemens Energy said it officially handed over units 30 and 40 of a combined cycle power cogeneration plant to Singapore’s PowerSeraya last week.

The new units have a fuel efficiency rate 75% higher than the three oil-fired plants on Jurong Island that they replaced.

Siemens built the turnkey, 800-megawatt (MW) plant in an open consortium led by Siemens AG in partnership with Siemens Pte Ltd Singapore and Samsung C&T of South Korea.

These high-efficiency combined-cycle units are configured for cogeneration, supplying electricity to the grid and process steam to a neighbouring plant owned by Petrochemical Corporation of Singapore Private Ltd.

“These high-efficiency cogeneration units will play a major part in meeting Singapore’s increasing energy requirements in an environmentally friendly and cost-effective manner,” said Rainer Hauenschild, CEO of Energy Solutions for the Fossil Power Generation Division of Siemens Energy.

In 2002, Siemens said it and Samsung Corporation jointly constructed two combined-cycle units for PowerSeraya on the same site, with each unit rated at 370 MW. These units were likewise converted to cogeneration in the course of the new construction project.

Completion of the new units means that PowerSeraya now has four combined-cycle units on Jurong Island with a total installed capacity of 1540 MW. The Siemens scope of supply for the new units covered two SGT5-4000F gas turbines, two hydrogen-cooled generators, the heat recovery steam generators together with all the electrical systems and the SPPA-T3000 control system.

Siemens was also awarded a service contract for these units.
