Siemens has been contracted to erect the most efficient and
environmentally friendly natural-gas-fired combined cycle
power plant (CCPP) in the world at the Dusseldorf port location
in Lausward. At the core of the plant is a Siemens H-class gas
turbine, which was awarded the German Industry Innovation
Prize this year. Together with a steam turbine, the Dusseldorf
plant will reach around 595 megawatts of electrical output,
which will set a new world record. The rejected heat is
planned to be utilized in a further process to provide the city
of Dusseldorf with district heating. Never before has it been
possible to extract 300 megawatts of district heat from a single
gas turbine power plant unit.
A twelve-year, long-term program (LTP) will secure high availability and state-of-the-art maintenance of the entire turboset. Siemens has individually tailored this service contract to
address the primary demands of the Stadtwerke Dusseldorf
AG for minimum investment cost and high flexibility.
Siemens lives up to its responsibility to comply with ethical and legal standards
in all its activities, both within and outside the company.

High Winds in Shallow Waters
84 Living Energy · No. 7 | November 2012
The 21 turbines that Siemens delivered to China’s Jiangsu Rudong Offshore
Wind Power Plant are ideally positioned to make the best use of winds blowing
off the coast 250 kilometers northeast of Shanghai. Placed in an intertidal zone,
they have dry feet in low tide, but are covered by up to 5 meters of water at
high tide. With an output of 2.3 megawatts each and rotor diameters as long as
a football field, the turbines will be able to generate up to approximately 50 megawatts. For ­Siemens, the project – which was completed in May 2012 – marked
the first order of offshore wind power technology outside of Europe, with key
components including rotor blades and
nacelles being built at production facilities in Shanghai. China is already the
world’s largest market for wind energy
and plans to install 30 gigawatts of
offshore wind power by 2020.
Siemens wants to be part of that development: “With more than 600 wind
turbines with a combined capacity of
more than 1,800 megawatts installed
in European waters, Siemens is clearly
the market leader in offshore. But we
also see good opportunities for offshore
wind power in China with its shallow

the Siemens Business Unit Wind Power.
A joint venture between the Stadtwerke München (SWM,
­Munich City Utilities in Germany) and Siemens Infrastructure
& Cities has created a virtual power plant in which a number
of small-scale, distributed energy sources are pooled and
­operated like a single installation, improving planning and
forecasting reliability in the area it supplies. The core component of this virtual interconnection is the Distributed Energy
Management System (DEMS) from Siemens, which ensures
optimum deployment and more efficient operation of decentralized energy sources and loads.
SWM’s virtual power plant combines six unit-type cogeneration modules, five hydropower plants and a wind farm in the
Munich area. It may be expanded by including further energy
sources and switched loads. “In the long term, this will help
counteract supply problems that arise when more of the infeed
comes from renewable energy sources, which is what smart
grid is all about,” says Stephan Schwarz, SWM Director for
Utilities and Technology.
A virtual power plant consists of multiple smaller decentralized plants (usually producing energy from renewable sources)
that are bundled and controlled by centralized steering software, allowing smaller producers of energy to achieve the critical mass necessary for participation in the energy market.

in per capita energy use, its energy consumption is still huge. The infrastructure
must constantly be expanded in limited space. New Jersey’s PSE&G utility equipped
the extension of its high-voltage substation in Bergen, which supplies power to
Manhattan, with Siemens gas-insulated switchgear (GIS). This technology is compact, yet innovative, featuring Siemens’ GIS circuit breaker for 245 kilovolts/
80 kiloamperes. Crucially, power continued to be supplied by the Bergen substation during construction – making the whole project an example of open-heart
surgery on New York’s power supply which includes a complex sequence of outages. Bergen is linked to Manhattan Island via a back-to-back HVDC link, also
supplied by Siemens, boosting grid stability in the Big Apple for years to come.
This year, the Siemens Infrastructure &

de Medição S.A. located in Belo Horizonte, Brazil. The market leader for smart
metering solutions in Brazil consolidates
­Siemens’ smart grid portfolio. Smart
metering improves energy efficiency by
collecting, processing and accessing
data and reducing operational costs. It
supports the introduction of distributed
generation and electrical vehicles, and
increases customers’ awareness of their
energy consumption. With a workforce
of approximately 100 engineers, Senergy
has profound expertise in providing
complete solutions for revenue assurance
and prevention of nontechnical losses
in the power distribution grid. In the
next years, Siemens will support the

The HVDC back-to-back link is a key element of the Black Sea
Transmission Network linking the Georgian and Turkish power grids.
Black Sea neighbors Georgia and Turkey
have embarked on a partnership of mutual
benefit for their respective power grids.
While demand for energy is growing in Turkey, Georgia has surplus hydropower for
sale. The solution is the Black Sea Transmission Network project, which will facilitate
electricity transmission via a Siemens-made
HVDC (high-voltage direct-current) backto-back link at Akhaltsikhe substation in
Georgia connecting the Georgian 500-kilovolt power network with Turkey’s 400-kilovolt grid without a direct connection between the two. Other improvements to the
existing network at Zestafoni and Gardabani
substations are also part of the project,
which was contracted by Energotrans in
Tbilisi and is scheduled for completion in
May 2013. It is anticipated that the deal
will stabilize grids on both sides of the border and be of economic benefit to both
countries.

­receive their award.
SeaGen, the world’s first commercial-scale, grid-connected
tidal stream energy system, has achieved a new milestone
of 5 gigawatt-hours of tidal power generation since starting
­operation at Strangford Lough in Northern Ireland in 2008.
That means that the turbine, which works much like an “underwater windmill,” currently has the capacity to meet the annual
power consumption needs for the equivalent of about 1,500
British households. The Siemens-owned system is one of the
largest tidal stream power projects today.
This latest milestone, adding an additional 2 gigawatt-hours
of power since January 2012, is an exciting development for
this proven technology, whose potential for commercial deployment as part of the future energy mix is now recognized.
Global carbon reduction commitments are increasing demand
for reliable marine current power. Experts are expecting double-digit annual growth rates for this sector up to 2020. The
worldwide potential for power generated by tidal power plants
is estimated at 800 terawatt-hours annually, or between
3 and 4 percent of global power consumption.

Siemens has opened its first center for
­sustainable urban development in London.
At the heart of the Crystal is the world’s
largest exhibition dedicated to sustainable
urban development. The crystal-shaped
building will serve as a conference center,
dialog platform, and technology and innovation center all in one, bringing together
political decision makers, infrastructure
­experts, and the general public in order
to develop concepts for the cities of the
21st century.
The Crystal, which covers an area of more
than 6,300 square meters, is a model of
energy efficiency. The facility consumes
50 percent less power and emits 65 percent
less CO2 than comparable office buildings.
Renewable energy sources satisfy the
­Crystal’s heating and cooling needs, a photovoltaic system generates green electricity, and rainwater is harvested for use.
On the BREEAM and LEED international
­assessments for energy-efficient buildings,
the Crystal will receive top scores (Outstanding and Platinum, respectively) –
making it one of the greenest facilities
in the world.
The new Enhanced Platform steam turbine design
is more efficient, allows more applications, and improves start-up time, availability, and maintenance.
Siemens introduced two new developments in its industrial steam
turbine portfolio at the POWERGEN Europe 2012 exhibition and
conference in Cologne: the new
Enhanced Platform steam turbine
design concept and the new
­SST-111 industrial steam turbine.
The Enhanced Platform design,
which includes individual standardized modules and optimized blade
geometries, will be deployed for
­Siemens industrial steam turbines
with outputs between 15 and 250
megawatts, resulting in higher
­efficiency, faster start-up, improved
availability, a broader range of
­applications, and greater ease of
maintenance.
In addition, Siemens – the market
leader for small industrial steam
turbines – has added a new turbine
model for outputs of up to 12
megawatts to its portfolio: the
SST-111. It combines the robustness and flexibility of a singlestage geared steam turbine with
the higher efficiency of a multistage steam turbine, making it especially ideal for small decentralized power generating facilities.
The multicasing design allows up
to two controlled steam extractions for different purposes and
the reheating of the steam.
