The population of the emirate of Abu
­Dhabi reached 2.3 million in mid-2013
and grew at a rate of 7.9 percent between 2005 and 2012, making it one of
the fastest-growing countries worldwide.
Migrant workers contributing to the
­Emirate’s economic boom play a major
role in this rapid increase. Both demographic and economic growth fuel a
sharp rise in power demand. Now, the
third combined cycle power plant at the
Shuweihat site in the emirate of Abu
­Dhabi has been handed over, turnkeyready. T
­ ogether with its Korean consortium partner Daewoo Engineering & Construction Co., Siemens designed, built,
and commissioned Shuweihat S3 to meet
Abu D
­ habi’s increasing power needs. In
addition, the plant will deliver power to
the emirate’s expanding industry –
­including the nearby Ruwais refinery.
Situated approximately 260 kilometers
west of Abu Dhabi, it is Siemens’ fifth
power plant in Abu Dhabi and one of the
Emirate’s most powerful and efficient.
The Shuweihat S3 combined cycle power
plant has an installed electrical ­capacity
of 1,600 megawatts and will be operated
by Shuweihat Asia O&M Company (SAOM).
The owner is Shu­weihat Asia Power
­Company (SAPCO), which is a consor­ umitomo ­Corporation
tium comprising S
of J­ apan, Korea Electric P­ ower Corporation, and the local utility Abu Dhabi
­Water & Electricity A
­ uthority ­(ADWEA).
But Shuweihat S3 excels not only thanks
to its highly efficient F-class gas turbines,
it is also a benchmark project in terms of
Siemens’ efforts to promote ­occupational
health and safety. At the Shuweihat S3
construction site, large numbers of workers of different nationalities worked in
changing contractor teams simultaneously on site, which makes c­ reating a contin-
uous safety culture ­rather demanding.
However, the challenge to implement the
company’s strict Environment, Health and
Safety (EHS) regulations (see also article
“The Zero-Harm Mind-Set” p. 52) was
met.
“The Siemens Zero-Harm safety program,
which focuses on improving safety culture from the top down, was implemented within the Shuweihat S3 project –
­encouraging all on site to be proactive
about managing safety. Siemens’ efforts
in working with our partners and our
­client on the project helped reduce the
risk for everyone involved during
­construction and commissioning,” says
­Lothar Balling, Head of Project Man­
agement at the Power and Gas Division
of Siemens. For a construction site of this
scale, this is an impressive achievement
and team effort.

Upgrade of German Offshore Grid and
GIS Technology Breakthrough
First SVC Installed in Colombia’s Industrial Sector
The new gas-insulated HVDC switchgear will reduce the size of
offshore converter stations.
With the installation of the third and
fourth high-tech offshore platforms for
German-Dutch transmission grid o
­ perator
TenneT in the North Sea, an important
milestone in efforts to expand the German
offshore grid has been reached. The converter stations HelWin1, ­BorWin2, SylWin1,
and HelWin2 are fully automated and designed for decades of ­operations in rough
seas. Together, the platforms from
Siemens will transmit 2.9 gigawatts of
wind-based electricity. This year, a fifth
converter station – B
­ orWin3 – was ordered. It will start transmitting in 2019.
The first Siemens SVC (Static VAR Compensator) for reactive
power compensation in Colombia’s industrial sector was installed at Gerdau Diaco’s steel production plant in Tocancipá at
2,560 meters above sea level. Static reactive power compensators boost the operational security and transmission capacity
of power grids thanks to voltage stabilization and power feed-in
The HelWin2 and SylWin1 DC links were
installed this summer. ­SylWin1 will be
the most powerful of the four offshore
grid connections – it can transmit sufficient wind power onshore to power
900,000 homes. With its dimensions
of 83 x 56 x 26 meters, it is the largest
­converter plat­form i­nstalled to date
worldwide.
However, with the recent breakthrough in
gas-insulated technology for DC switch­
gear, the converter stations of the future
are set to be significantly smaller. Until
now, air-insulated equipment has been
the only solution for DC. The 320-kilovolt
gas-insulated HVDC switchgear has
­already reached market maturity, and the
500-kilovolt equipment is currently being
tested. In the 320-kilovolt configuration,
the gas-insulated DC switchgear uses up
to 95 percent less space than its air-­
insulated predecessor. This will result in
substantial cost savings, since offshore
platforms are extremely expensive.

Wind Turbine
for High Yield
at Low-Wind
Sites Launched
In September at the WindEnergy 2014
trade show in Hamburg, Siemens introduced its new SWT-3.3-130 wind
­turbine, developed to extract the
­maximum energy yield from low to
moderate wind speeds. With its
3.3 megawatts of electric power and
remarkable diameter of 130 meters,
this wind turbine will be available in
early 2017. It is a perfect fit for the
growing number of onshore wind power plants that are being built in regions
with moderate to low wind speeds.
This new turbine will exceed the annual
energy yield of the previous D3-series
wind turbines (SWT-3.0-113 and SWT3.2-113) by approximately 17 to
20 percent. Five years of experience
gained from the D3 platform have
­enabled engineers to fundamentally rework the main components, such as
the direct-drive PMG generator – which
now operates with even stronger permanent magnets to further enhance
output.
More wind turbine innovations are already lined up: Siemens has obtained
type certification by certifying body
DNV GL for the D6 offshore wind turbine. The model SWT-6.0-154 is based
on proven direct-drive technology, rated at 6 megawatts, its rotor spanning
an impressive 154 meters.

By acquiring Rolls-Royce’s aero-derivative gas turbine, compressor, and ­service business for £785 million (€940 million),
Siemens is strengthening its position in the growing oil and gas
industry as well as in the field of ­decentralized power generation. “The small to medium aero-derivative gas turbines up to
66 megawatts close a technological gap in our gas turbine portfolio,” says Roland Fischer, CEO of the Power and Gas Division.
Rolls-Royce’s gas turbines were originally developed for the aviation industry. The weight-optimized turbines are compact and
very efficient, making them an interesting option for offshore
platforms with limited
space, for example.
Siemens further purchased exclusive access to
future technological developments in aviation
turbines from 4 to 85
megawatts and preferential access to delivery and
engineering ­services.
In the open desert, the gradual construction of no less than 131 turbines is producing a spectacular landscape.
The Moroccan government has set itself
the target of raising the contribution
of ­renewable energy to 42 percent of the
national energy consumption by 2020.
Under the framework of this ambitious
government project, Siemens provides
400 megawatts from its installed bases
throughout the country. Upon commissioning in the end of 2014, one of these
installations – located in Tarfaya in the
south of Morocco on the Atlantic coast –
will be Africa’s largest onshore wind
power plant with an output of 300 megawatts. Tarfaya’s wind farm required
Siemens to deliver and install 131 SWT2.3-101 wind turbines – the designation indicating a power rating of
2.3 megawatts and a rotor diameter
of 101 meters – under a five-year
­service agreement. The customer is a
joint v­ enture between Morocco’s N
­ areva
Holding and International Power Ltd.,
which is part of the GDF SUEZ Group.
In addition to the wind farm, Siemens
also made a commitment to give the
­local population access to b
­ etter education and healthcare by providing a
school bus and an ­ambulance, as well
as IT equipment.

Central Control of
Heterogeneous Generation
Fleets
A recent innovation to Siemens’ I&C system SPPA-T3000 allows the central
operation of numerous power plants with dissimilar I&C systems. SPPAT3000 can be set up in a multiunit configuration using a new homogenization concept: A transformation ­server is installed at every plant to “translate”
the data from the original systems into the SPPA-T3000 data structure. With
the system’s uniform operating and alarm h
­ andling philosophy, operators in
the central control room thus have control over the entire fleet at all times as
if it were one single system.
This solution minimizes operational costs and, at the same time, requires
only low ­investment, thanks to the retention of existing control systems in
each plant.
