Cost-effective and ecofriendly
power supply
Since October 2010, two new blocks at PowerSeraya’s
combined-cycle power plant have been operating as a
cogeneration facility to produce both heat and power.
We’ve supplied the plant with two gas turbines, two
steam turbines, two hydrogen-cooled generators, two
waste heat boilers and a control system. We’ve also pro-
vided all the plant’s electronics. By supplying process
steam to an adjacent refinery as well as feeding electric-
ity into the grid, the plant has increased its thermal
efficiency to over 75%. We’ve also signed a contract for
another 800-megawatt power plant on Jurong Island.
The well-proven configuration of a single-shaft com-
bined-cycle unit will boost the plant’s operational effi-
ciency well beyond the 58% mark at ambient conditions.
CO2 emissions at the plant, which is scheduled to go on
line in 2013, will also be considerably reduced. In both
projects, we’re helping Singapore meet its growing need
for cost-effective and ecofriendly power.
Singapore Post Centre
Singapore Post is the city-state’s domestic and interna-
tional postal service and its leading logistics provider.
Since 1998, Singapore Post has been working closely with
us to ensure – with the help of our automation systems –
that every piece of mail reaches its proper destination.
Roughly three million pieces of mail pass through the
Singapore Post Centre every day. We’re now installing
a multi-sorter system that will further enhance the effi-
ciency of the Centre’s mail-handling process and, thus,
boost the postal service’s competitiveness.
Driverless metro line
Boasting a state-of-the-art public transportation system,
Singapore leads the world in driverless subway opera-
tions. The city ’s Downtown Line – the first phase of
which is scheduled for launch in 2013 – will considerably
shorten travel times for up to 500,000 commuters daily.
We’re equipping the new driverless metro line, which will
be 40 kilometers long and have 33 stations, with efficient
rail power technology. Inverters in substations will feed
excess braking energy back into the medium-voltage
grid. The result: enhanced energy efficiency and environ-
mental sustainability.
Khoo Teck Puat Hospital
Khoo Teck Puat Hospital is the city-state’s newest public
hospital and one of the world’s most ecofriendly medical
facilitites. Opened in 2010, the 550-bed hospital provides
the more than 700,000 residents of Singapore’s northern
sector with an extensive range of healthcare technolo-
gies. Our contributions include angiography systems and
computed tomography scanners such as the SOMATOM
Definition Flash.
Marina Bay Financial Centre
The Marina Bay Financial Centre, an extension of Singa-
pore’s central business district along Marina Boulevard,
is powered and protected by Siemens solutions. We’re
supplying and managing the Centre’s security systems,
fire alarm systems and Sentron low-voltage busway
system.
