Strategy
There is no doubt: Europe is passionate about renewables and Vattenfall intends to
be among the leaders of this energy transition. The company’s wind energy portfolio
will increase to around three gigawatts in operation by 2016.
What is the rationale behind Vattenfall’s clear focus
on wind energy?
Magnus Hall, CEO and President of Vattenfall: First of
all, we have adopted a very clear strategy involving
a shift from conventional power to low-emission or
carbon-free power sources. For us, wind energy is
driving change in the energy landscape. We are re-
ducing our carbon footprint by cutting our emissions
of greenhouse gases through the expansion of wind
power. The vast majority of our growth investments in
the coming years will therefore be dedicated to wind
power.
Vattenfall is due to invest €1 billion in wind power
over the next two years. Is that enough to fund your
visions?
Hall: We have already invested €5 billion in onshore
and offshore wind energy projects in recent years
and we want to continue with this growth. Obvi-
ously, the more capital that is available, the greater
our contribution to the energy transition can be. We
will therefore be stepping up our cooperation efforts
with partners. We feel fit for this as we have already
gained good experience on recent projects.
Gunnar Groebler, Senior Vice President of Vattenfall
and Head of Business Area Wind as of 1 April 2015:
Yes, we have some good examples of partnerships.
For instance in Germany, where we cooperate with
the utility Stadtwerke München on the DanTysk and
Sandbank projects. Another example is in Sweden,
where we have started a joint venture with the insur-
ance company Skandia on four onshore wind farms.
Beyond this, we have had success in collaborating
with private investors in the Netherlands and Den-
mark. Taking financial investors on board is definitely
something we will pursue further.
Why would investors be interested in investing in
Vattenfall’s wind projects?
Groebler: Because we have world-class competen-
cies in project development and the construction and
operation of wind farms. We are the second largest
player in offshore wind worldwide. The financial mar-
kets are interested in this kind of investment because
it offers an attractive risk-return profile to investors.
Hall: Our experience and skills give us a strong com-
petitive edge in wind energy and this is something we

damental part of Vattenfall’s
future low-emission energy
mix.”
Magnus Hall
“As the second largest
player in offshore wind, we
have built up world-class
competencies.”
Gunnar Groebler
will build on: In Denmark, we are the largest operator
of onshore wind farms, while in the Netherlands we
are the largest general operator of wind power. The
UK is also an important market, where since 2009
we have installed 557 megawatt of capacity. And our
offshore wind farms in the North Sea make us one
of the top contributors to the energy transition in
Germany.
What are the main challenges for the wind energy
industry?
Hall: A big challenge involves meeting our customer’s
expectations to deliver more renewable electricity
that is both reliable and affordable. It goes without
saying that we want to further reduce the overall
level of energy costs. It is our ambition to exploit of
our leading role and shape wind energy further as a
competitive technology. We are therefore constantly
working to generate renewable energy at the lowest
possible cost.
Groebler: We are also committed to understanding en-
vironmental impacts and delivering world-class com-
munity engagement. I am not afraid to say that we
are second to none when it comes to proactively pro-
tecting and preserving the environment. We always
try to anticipate any potential damage and mitigate
the effects in the best way possible, which can be
seen in several good examples. In the UK, for in-
stance, our proactive approach to mitigating environ-
mental impacts likely played a key role in the granting
of the permit for our onshore Pen y Cymoedd wind
farm in Wales. With respect to community engage-
ment, we come up with tailor-made solutions wherev-
er possible and cooperate with the community more
deeply than we are obliged to. We are very proud of
the fact that this approach has already made us the
developer of choice for many communities.
Looking to the future, what role will wind power play
at Vattenfall?
Hall: As an important part of our response to our
customers’ expectations, wind energy will be a funda-
mental part of Vattenfall’s future low-emission energy
mix. Those expectations are high because customers
demand that we contribute to a sustainable world in
everything that we do. And this is what we are com-
mitted to.

are leading efforts to develop Vattenfall’s wind energy portfolio

growing with
partners
1. 2. 3.
Renewable power is growing in popularity across
Europe and attracting billions of euros in outside
investment. This year, Swedish insurance giant
Skandia is partnering with Vattenfall to build and
commission four wind farms. While three are still
under construction, the first one is already in opera-
tion. Skandia’s investment is enabling expansion
with renewables at a faster pace, representing not
only a win for Vattenfall but also for its partners,
customers and the environment. The joint venture
comprises the Juktan (nine turbines), Höge väg
(18 turbines), Högabjär-Kärsås (12 turbines) and
Hjuleberg (12 turbines) wind farms. Together, they
can supply enough electricity for 80,000 homes.
Utilities are natural partners in the production of
renewable electricity. Stadtwerke München (SWM)
supplies electricity, gas and water to the residents
of Munich and is one of Vattenfall’s most important
partners. The two companies came together and
invested more than €2 billion to build and operate
two major offshore wind farms, DanTysk and Sand-
bank, which have a combined output of 576 MW.
“SWM is aiming to produce enough green electricity
at its own plants by 2025 to meet the power re-
quirements of the entire municipality of Munich. This
would make Munich the first city in the world with
over a million inhabitants to achieve this goal,” says
Dr Florian Bieberbach, head of the SWM Executive
Board. “We therefore need strong, reliable partners
such as Vattenfall.”
Vattenfall has a long track record in partnering
with local landowners and private investors around
the world. For example, in Denmark, at least 20 per
cent of the ownership of wind farms is offered to
neighbours. While other companies offer shares
in specific turbines, Vattenfall offers shares in the
entire farm. In other countries, Vattenfall pursues
different financial participation models to involve
stakeholders and improve local acceptance of
wind energy. “At the Nørrekær Enge wind farm, we
now have 77 positive ambassadors who have been
working hard with us to obtain approval from the
municipality for an expansion of the farm,” says
Arne Rahbek, communications advisor at Vattenfall
Denmark.

chain. This means that the company can build on
a tremendous mix of experience, transparency and
performance from start to finish. Read on to find out
more about the partnering models Vattenfall em-
ploys.
It is vital for Vattenfall, when working with others, to stick to its core
values: safety – cooperation – performance. We aim to build long-term
relationships with financial partners, utilities and local stakeholders.

since 2009
After finishing my engineering studies in Greece,
I decided to dedicate my time and energy to doing
something useful for our environment. I came to the
Netherlands for a Masters in sustainable energy
technology and became specialised in wind energy.
Now I am responsible for wind resource assessments
at Nuon. I can share knowledge with my colleagues
across Europe and learn from their experience of
operating onshore and offshore wind farms. That’s
why I like working with Vattenfall wind.
I am a trained glassblower and had my own business.
Then I felt like doing something else and was offered
co-ownership of a lunch restaurant. A few years
ago I became interested in wind power and found a
program to become a service technician. Now I work
on maintenance and troubleshooting of the 40 Stor-
Rotliden turbines in northern Sweden and I really
enjoy the diversity of work here.
I have a geoscience background, having spent seven
years working globally in oil exploration and produc-
tion before moving to the renewables sector in 2005.
I am currently responsible for safe delivery of the
228 MW Pen y Cymoedd wind farm in the south of
Wales. An enormous challenge, but I have a great
team.

When I was thinking about moving to Europe, I de-
cided to use the opportunity to let my career take
a change of direction from the development and
manufacture of aircraft to the development and
construction of wind farms – after all, they both rely
on moving air! South Africa is a country with an as-
sortment of cultures and part of what attracted me
to Vattenfall was the wide diversity of nationalities in
the teams and in the company.
60people of 13different nationalities are working
on the Sandbank offshore project

XX. Section Biodiversity
Biodiversity has been reduced by modern and in-
dustrial methods of farming. Old ponds, ridges and
meadows have disappeared, but the construction of
wind farms opens up the opportunity to help wildlife
to return. When Östra Herrestad was constructed in
2010, five biotopes were established in the wind farm
under a cooperation arrangement with the Swedish
Board of Agriculture. The biotopes were established
with a mix of different methods and approaches:
berry bushes, rose-hip and crab apples were planted
alongside sunflowers, and feeding places were pro-
vided for small birds and insects. Artificial habitats
were formed around the wind farm by using wood,
sand and pools of water around the farm.
NEW LIFE AT THE FOOT
OF WIND POWER
From our wildlife sanctuary constructed at the Östra Herrestad wind farm
in southern Sweden to the depths of the North Sea, Vattenfall works to
protect wildlife across Europe and beyond.
David Stålberg, project manager at the Swed-
ish Board of Agriculture: “The cooperation with
Vattenfall has been an opportunity for us to test the
biotope idea in real-world conditions. It has also con-
tributed to generating positive interest in biodiversity
within a totally new context. Having a big energy
company such as Vattenfall invest in nature conser-
vation is incredibly positive and an encouragement
for our future environmental work.” After a few years,
positive effects can be seen in the presence of im-
portant insects and plants, and this initiative is one
of many contributions to a larger scheme to increase
biodiversity in this landscape.
increase their contrast with the sky. The researchers
hope that this will help birds detect and avoid the
blades more easily. The team is also investigating
the effect of similarly increasing the contrast on the
pylons and using paint that reflects ultraviolet light
to help birds avoid collisions, both onshore and off-
shore. In various research programmes in partnership
with industry and other key stakeholders, Vattenfall
wants to learn more about the impact of offshore
wind farms on birds.
Protecting marine life
Marine areas provide not only ideal conditions for
wind farms but are also an ideal habitat for a wide
range of plants and animal species. When building
a wind farm, one important task involves protecting
harbour porpoises, a species which is sensitive to
the sound of pile driving for the foundations. Very
little, however, is known about their behaviour, and
to find out more, Vattenfall specialists are actively
involved in a research project at Aarhus University
in Denmark, together with six other offshore devel-
opers. The information obtained will be fed into a
scientific simulation (the DEPONS model), which will
be used as an evidence-based tool for assessment
of the harbour porpoise population consequences of
individual and multiple wind farms.
At the German DanTysk wind farm, a number of
measures were adopted to mitigate noise. Apart
from using seal scares prior to piling to make the
animals leave the site, a new method of accentuating
noise by means of currents of air bubbles around the
installation vessels was adopted.
Biodiversity: protect
nature and endangered
species
Biodiversity, short for biological diversity,
is the term used to describe the variety of
life found on Earth. All energy sources im-
pact nature in some way, and it is crucial
that Vattenfall minimise its impact on flo-
ra and fauna at each individual site. The
biodiversity area covers handling impacts
on ecosystems, species and genetic vari-
ation at each stage of our operations:
project planning, construction, operations
and decommissioning/dismantling.
It is Vattenfall’s goal to implement the right envi-
ronmental solutions. We have therefore brought in
a proactive biodiversity management team to run
these activities in a range of scenarios such as min-
ing areas, decommissioned sites or at wind farms.
The promotion of biodiversity and wildlife conserva-
tion can be seen from the following examples in Ger-
many, Norway and the North Sea.
From lignite to wind
In eastern Germany, Vattenfall built the Jänschwalde
wind farm on the site of a former open-cast lignite
mine. This is a great example of how an old mine
can be repurposed and become a symbol of the
transition from conventional to renewable energy.
Vattenfall is looking into further opportunities to
develop similar sites for wind energy. Jänschwalde
has six turbines of 2 MW each, delivers electricity to
7,000 households and was commissioned in 2004.
Vattenfall is also active in peatland and upland
habitat restoration in the UK. For example, we have
invested £3 million to protect and enhance this im-
portant ecological feature at our Pen y Cymoedd
wind farm in Wales.
Painting for life
At Smøla wind farm in Norway, Vattenfall is involved
in a research project with the Norwegian Institute for
Nature Research to mitigate the risk of birds such
as eagles being killed by turbine blades. Advanced
technology such as GPS tracking, radar and video
surveillance is being used. One of the proposals be-
ing evaluated is to paint the rotor blades black to
“The cooperation with Vattenfall
has been an opportunity for
us to test the creotope idea in
real-world conditions.”
David Stålberg, project manager at the Swedish Board of Agriculture
The nine turbines of the Östra
Herrestad wind farm are a prime
example of how Vattenfall has
managed to balance business
development and environmental
conservation

XX. SectionLocal participation
Implementing a wind farm is not an easy task at the
best of times; without support from the local com-
munity, it would be an impossible one. That’s why, at
Vattenfall, we work extremely hard to engage with
and work alongside the local community. An example
of this is the Wieringermeer wind farm in northern
Holland.
Commissioned in 2003, the wind farm sits on re-
claimed land that a hundred years ago was under the
sea. The project is a partnership between Vattenfall,
a coalition of farmers that operates 34 isolated tur-
bines and the Dutch national energy research centre
ECN. The goal of the project is to replace 39 exist-
ing turbines that are spread unevenly across the
landscape with a hundred state-of-the-art turbines
placed together in tight formation. This will make the
area look tidier and feel calmer, while tripling output
to between 300 MW and 400 MW.
To secure good relations with the neighbours of the
future wind farm, a community council has been
established with ongoing dialogue between local
residents, environmental groups and business organi-
sations.
Gerard van Oostveen, Wieringermeer project direc-
tor, sees a lot of value in the community council. “Of
course we don’t always agree on all aspects of the
wind farm. But the council gives us a platform to
openly discuss participation, noise mitigation and
other issues. In the end, a joint solution to these is-
sues will lead to better relations with the wind farm’s
neighbours, and that is of critical importance to us.”
The council is consulted on issues such as participa-
tion and noise mitigation. Those living within 1,200
meters of a turbine will also be compensated, and
a regional fund is being set up to support develop-
ment in the area. Residents also have the option to
buy shares in one of the turbines in exchange for
reduced electrical bills.
TAlks with
neighbours
The growth of onshore wind power could not exist in the absence of vital
and rewarding long-term ties with local residents. For the first time in the
Netherlands, a community council gives locals a real say.
Local Participation
Wind farms can have a significant
impact on the local area and communi-
ties. That’s why Vattenfall develops wind
farms with the greatest respect for the
local area and host communities. Local
participation takes many forms, but at
its core are the relationships between
us and the community in which we do
business. It gives those in the local area
the chance to have a say in the issues
that affect them closely. In addition, we
look at best practices in terms of finan-
cial participation so we can contribute
to local ownership and acceptance of
wind farms. We do this in each market
and in close collaboration with local
communities and authorities.

Wind energy creates jobs in local communities. One
such example is the Pen y Cymoedd wind energy
project in the south of Wales, where construction
started in 2014.
Vattenfall, with strong support from Welsh business,
will take four years to build Pen y Cymoedd. After
only a year, over £45 million worth of contracts have
been placed with businesses in the local community,
securing 600 jobs and supporting more than 50
companies. With a predicted lifespan of twenty-five
years, the project is expected to inject up to
£1 billion to the Welsh economy.
Alongside the economic boost to the supply chain,
the Pen y Cymoedd project will also benefit local
communities to the tune of around £1.8 million per
year through a community fund. A recent campaign
from Vattenfall known as “Power in the Valleys”
asked the local population how the fund can make a
major difference to the area.
In addition, Vattenfall has funded the construction of
a £350,000 mountain bike trail through the Afan For-
est Park, and has pledged to fund its upkeep for the
next decade. Louise Davies, manager at Afan Lodge,
says that “the tourism industry in the Afan Valley is
very young and this investment, and the publicity we
will get from it, will be invaluable.”
Wind farm projects have the potential to boost the local economy.
In Wales, more than 600 jobs have already been secured with the
construction of Vattenfall’s Pen y Cymoedd wind farm.

WIND ENERGY
CREATES LOCAL JOBS
Economic benefit
The growth of the renewable industry sector
has proven to be an important factor in the
development of national and regional econo-
mies. The economic benefits are seen not only
in the core of the wind industry but also in
companies along the entire supply chain and
in the surrounding area. Jobs created in a local
economy can be found in supplies, logistics,
facilities such as schools, local retail and tour-
ism.
Offshore wind energy also boosts local econo-
mies in coastal areas across Europe, where
many jobs have been created in service and
maintenance.

In onshore wind energy, the Netherlands and Denmark are Vattenfall’s most
important markets. With nearly identical production of around 560 Gwh/year
in 2014, both countries together account for 70% of Vattenfall’s production
of onshore wind energy.
In offshore wind energy, Vattenfall generated more than 60% of its offshore
electricity in the UK. By the end of 2017, Vattenfall will generate one third
of its electricity from offshore wind in Germany, mainly at the fully-commis-
sioned DanTysk and Sandbank wind farms.

XX. SectionRepowering
Health Safety is always top priority at
Vattenfall and one of our core values. In
fact, the company’s renewable business
has set itself the ambitious target of
achieving zero injuries as the technology
continues to develop at such a fast pace.
We have implemented a leadership pro-
gramme to make sure everyone has the
same understanding of risk prevention,
focusing on systems, people and design
processes.
Safety first
The technology of wind power has developed in giant steps over recent
years and wind turbines have become significantly more powerful. At the
Klim wind farm in Denmark, Vattenfall is increasing production fivefold.
Turbines repowered
in Denmark
Klim, in northern Jutland, has been one of Vattenfall’s
largest onshore wind farms since it began operation
in 1996. Nearly twenty years later, the wind farm has
reached the end of its lifespan and will be repowered:
Vattenfall is erecting 21 modern turbines to replace
the 35 smaller, older units. This change will make Klim
the most powerful wind farm in Denmark. The old tur-
bines will find new life in countries such as Italy and
Ireland, where they will be recommissioned.
Denmark has always been at the forefront of wind
energy, having pioneered commercial wind power
nearly forty years ago. Today, 40 per cent of its elec-
tricity generation comes from wind energy. Vattenfall
has been active in the country since 2006, when
it entered the market through acquisitions, and is
today the largest operator of onshore wind energy in
Denmark.
Klim wind farm is a flagship Vattenfall programme
in Denmark, and the company’s relationships with
the local community have come to be regarded as a
best practice. This success makes it more likely that
Vattenfall will be granted permission to erect new
onshore wind farms in Denmark, where available land
for expansion with large-scale wind farms is limited.

XX. Section Offshore
Offshore:
backbone of the
energy mix
The 80 towering wind turbines in the DanTysk wind farm cannot be
seen from the German North Sea coast, but they are making a major
contribution to the power grid.
DanTysk is one of the first offshore wind farms
built in the German North Sea. The project involved
considerable complexity because all aspects, includ-
ing people as well as the enormous equipment and
machines, had to mesh perfectly at exactly the right
time, just like the pieces of a puzzle. And that had to
be done 90 km off the coast in a rough environment
and changing conditions dictated by the weather.
The first kilowatt hour was produced in December
2014.
Right in the middle
A team of more than 60 Vattenfall specialists, mainly
based in Hamburg, were involved in the construction
of the wind farm. The world’s largest installation ves-
sel, the Pacific Osprey with an overall length of 160
metres, transported up to 10 turbine sets at a time
to the installation site, a unique achievement. When
the weather cooperated, up to 10 turbines could be
installed in 10 days.
During the installation period, some team members
relocated from the office to the installation site and
monitored the construction process from a hotel ves-
sel, where they spent their time between work shifts.
One of them was Christian Stein, project engineer
for wind turbine systems: “Right in the middle of an
offshore wind farm project: what a great workplace!”
Follow-on project ready to go
From the start of offshore construction in early 2013
with the installation of the first monopiles to project
completion, Vattenfall acquired valuable experience
that goes directly into the next project: Construction
of the Sandbank offshore wind farm, next to DanTysk
and not far from the Horns Rev wind farm, starts in
2015. Vattenfall is responsible for planning, building
“I like the challenge on this
type of project, especially
offshore, as it is pretty much
at the edge of what is tech-
nically possible.”
Benjamin Koss, Project Manager Civil Works
and operating the two German projects in a joint
venture with Stadtwerke München.
Horns Rev offshore wind farm
Horns Rev was Vattenfall’s first offshore wind farm
and built in 2002. Barely 20 kilometres from the
coast of Jutland in northern Denmark, Horns Rev is
one of the world’s largest projects of its kind with
80 turbines supplying electricity to 150,000 homes.
Extensive environmental surveys were carried out
before and during the construction of Horns Rev to
identify the impact of its construction on the local
flora and fauna, with the results indicating that wind
turbines were places where plants and wildlife could
thrive and grow, resulting in increased food for fish,
porpoises and seals. The studies also found that
there was little impact from the wind farm on bird life
as migratory birds tended to avoid the turbines.
Offshore wind energy
Offshore wind energy is the fastest growing power sec-
tor in Europe. Its strength lies in its abundant ability to
harvest energy and its strong and stable winds. Wind
turbines at sea can provide electricity 340 days per year,
and thus contribute to a stable power system.
Offshore wind energy has the highest base load capacity
of all forms of renewable energy. The technology is rela-
tively young, so the learning curve offers great potential
to boost efficiency on follow-on projects. Vattenfall is tak-
ing a pioneering role in helping to shape a young growth
industry, and with an installed capacity of 1 gigawatt is
the world’s second-largest offshore operator.

Offshore wind in the UK
Sitting alongside one of the busiest shipping chan-
nels in the world, Vattenfall’s 100-turbine Thanet
wind farm in the English Channel will celebrate its
fifth anniversary this year. When it started operations
as the world’s largest offshore wind farm it paved
the way for the even larger projects now following in
UK waters. Vattenfall’s pioneering spirit goes back
further with the 30-turbine, ten-year-old Kentish
Flats scheme, one of the first Round1 projects in the
UK. Also, a glimpse into the future of offshore wind
can be found in the Irish Sea with the first-of-a-kind
30-turbine Ormonde wind farm and its innovative
foundations supporting some of the largest wind
turbines in the world. When the 15-turbine exten-
sion to Kentish Flats is completed this year, Vatten
fall’s largest offshore market, the UK, will have four
wind farms, consisting of 175 wind turbines and
590 MW – enough to supply 421,000 households
with green electricity.
The Kentish Flats Extension and Sandbank wind farm both benefit from lessons
learned on prior projects. Both are among the first to use a new efficient technique
to assemble towers for offshore wind turbines.
Due to the harsh environment on an off-
shore wind farm, a solid foundation struc-
ture is essential to ensure the wind turbine
can remain in service for a long time. The
foundation for each turbine consists of two
components, the monopile and a transition
piece or cage.
The transition piece was previously grouted
into place, but developments now make it
possible to fasten the different parts by
using flanges instead. This is one example
of Vattenfall’s work to continuously improve
processes and technologies, making it pos-
sible to increase efficiency and reduce the
costs of renewable projects.
The flange connection method has a number
of advantages, including:
• Mounting monopiles will make installation
much faster. This in turn means that the
time spent using expensive installation
vessels can be reduced.
• The installation will also be safer and less
weather-sensitive, and maintenance work
and the effort taken to dismantle the tur-
bines more straightforward.

XX. SectionOperation
Esbjerg – the EVER-
PRESENT eye
Safety and availability is everything, and when the
people on the sites leave for home, the Esbjerg
centre takes over. “When something makes a turbine
stop, we immediately try to get it going again,” says
Jan Jørgensen, manager of the surveillance centre.
“In 2014, we restarted 2,139 turbines that had
stopped outside normal working hours. This way, we
saved 14.7 million kilowatt hours that would other-
wise have been lost.” The surveillance centre is one
of the largest in northern Europe and monitors every
single turbine operated by Vattenfall. The employees
are able to stop or start the turbines remotely when
needed. “Availability is the key word in our business,”
says Jørgensen. “The surveillance centre has im-
proved the early warning systems to further increase
uptime, maximising cost-effectiveness. Our mantra is
to make unscheduled events scheduled.”
Vattenfall’s 1,000 wind turbines defy the forces of nature from the icy
Swedish mountains to the stormy waters of the Irish and North Sea.
The Esbjerg surveillance centre keeps an eye on all of them.
The system is unique in that it handles input from
some 50 different types of turbines. Data are
collected and categorised and then used for opti-
misation and planning. Since 2002, Vattenfall has
invested some €5 billion in wind power, and now the
surveillance centre is supplying the trading floors in
Amsterdam, Hamburg and Stockholm with vital data
on the number of Vattenfall turbines available as well
as those out of operation due to faults or service.
The centre is also important for the safety of the
workers. “The service technicians call us when they
enter the turbine and when they leave again,” says
Jørgensen. “It is an important safety measure that
was first introduced in our onshore turbines in Den-
mark and Sweden.”
The surveillance centre transmits availability data for all Vattenfall turbines to Vattenfall Energy Trading in Amsterdam, Hamburg and Stockholm
Quiet rooms with a shower, internet access and tele
visions will make everyday life more comfortable for
the service team at the DanTysk and Sandbank wind
farms. These wind farms will benefit from a unique
concept in the North Sea and share an offshore ac-
commodation platform situated in the middle of the
DanTysk wind farm. The building will provide space
for 50 people who work in shifts 365 days per year.
The platform is pleasant to live on and of great
strategic advantage to Vattenfall, as it reduces the
amount of time spent in transit by the crew, who now
live offshore in shifts but do not have to travel each
day from Esbjerg to DanTysk. In addition, mutual
utilisation with the Sandbank project makes the
operation even more efficient.
“We aim to achieve great synergies here in the
operation of the three wind farms, Horns Rev,
DanTysk and later also Sandbank. We partly use
same vessels, infrastructures and facilities. This is an
important way to reduce costs and make renewable
energy more affordable,” says Martin Reinholdsson,
Head of Wind Generation.
Efficient operation
Vattenfall saw the ingenuity of an offshore accommodation platform in the oil and gas industry, and shrewdly adapted it for a wind farm

Storage
Grid stability and energy storage technology are topics that are central to the new
energy landscape. To maintain a reliable power supply, it is necessary to devise
smart concepts for the integration of volatile renewable energy.
Smart
METHODS of
integration
19 Gwhof electricity are produced at Vattenfall’s
wind farms on an average December day.
This is the equivalent capacity of Vattenfall’s
pump storage plants in Germany.
Wind and solar energy are a perfect match. Vatten-
fall has embraced this and developed a solution for
the hybridisation of wind and solar energy by placing
solar panels between the turbines on onshore wind
farms. Due to their nature, it is rare that both wind
and solar power hit peak time at the same point so
electricity generation is maintained at a fairly steady
rate. The merging of these two technologies pro-
motes efficiency as they work on the same infra-
structure and connect to the grid at the same point.
This concept enables the more efficient integration
of renewable energy into the existing generation
portfolio and grid.
Second life
Battery storage is an innovative part of a renewable
energy system. It is because of this that Vattenfall is
pioneering a project known as “Second Life”. It is run
in cooperation with the BMW Group and sees elec-
tric vehicle batteries being recycled for energy stor-
age needs. As part of the project, the companies are
working together to develop a 2 MW battery with a
storage capacity of around 1.6 MW hours. Also being
explored are the possibilities of integrating electro-
mobility, renewable energy and energy storage units.
Connecting countries
A big opportunity for the European power grid of the
future is interconnectivity. In the UK, therefore, our
interests extend beyond wind farms to involvement in
a number of exciting projects such as NorthConnect.
This is an interconnector to directly connect the
UK’s electricity network with Scandinavia and will
improve security of energy supply while helping to
keep customer costs down.
Vattenfall comes from Waterfall
Hydro power is one of our key areas of activity.
Today, around 50 per cent of all Swedish electric-
ity generation comes from hydro power. Big hydro
power stations regulate their production almost
9,000 times during a year and help to stabilise the
grid. In Germany, Vattenfall runs the largest fleet of
pump storage power plants, which can be connected
to the grid at full capacity in a little over a minute-
and-a-half. They are valuable energy storage systems
with high efficiency and the ability to balance grid
stability.
