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

“Wind energy will be a fun-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.

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.

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-

sortment of cultures and part of what attracted me

to Vattenfall was the wide diversity of nationalities in

the teams and in the company.

60 people 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

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.

the growth of the renewable industry sector

has proven to be an important factor in the

development of national and regional econo-

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.*1 0.8 GW owned by Vattenfall | *2 4.2 twh Vattenfall share

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-

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.

eneRGy Mixthe 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.

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.

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 north Connect.

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.
