INTERVIEW<br />
COOPERATIVES DELTAWIND & ZEEUWIND:<br />
JOINING FORCES<br />
IN THE LARGEST<br />
CITIZEN’S INITIATIVE<br />
A unique wind farm is emerging around the Krammersluizen, with 34 wind turbines that<br />
have a total capacity of 1<strong>02</strong> megawatts. The initiators of this wind farm in and around the<br />
Krammersluizen are in fact the 4,800 members of the Zeeuwind and Deltawind cooperatives,<br />
making Windpark Krammer the largest citizens’ initiative of the Netherlands. Construction<br />
began in January 2017, and the wind farm should be operational next year.<br />
ERIK VAN HUIZEN<br />
21 of the 34 wind turbines are already in position<br />
at Windpark Krammer, with a height of 125 meter<br />
and with 56 meter long rotor blades that weigh 26<br />
tonnes. The turbine’s weight, including tower and<br />
foundation, equals 4,381 tonnes. Approximately<br />
3,000 employees will work on the wind farm in the<br />
forthcoming period, an average of 200 people per<br />
day and 650 unique individuals each week. The<br />
ascending tower cranes are also striking features.<br />
There are only four of these cranes in Europe, three<br />
of these are presently used for constructing this<br />
wind farm. 95% of the wind farm’s power is sold<br />
to four multinationals, namely Google, AkzoNobel,<br />
DSM, and Philips, without intervention from an<br />
energy company. As Windpark Krammer is a citizens’<br />
initiative, the consumer in this case supplies<br />
the industry.<br />
DELTAWIND COOPERATIVE<br />
As a local cooperative, Deltawind also owns, alongside<br />
its share in Windpark Krammer, a total of 22<br />
MW of installed wind capacity and a 0.85 MW solar<br />
farm. The cooperative currently has 2,500 members,<br />
all of them are inhabitants of the island. With<br />
wind farms Battenoert (40 million kWh per year)<br />
and Piet de Wit (43 million kWh per year), Deltawind<br />
is now already producing more than the electricity<br />
consumption of all the Goeree-Overflakkee<br />
households combined. Deltawind expects to build<br />
another 9 MW on the island in the years to come.<br />
This will bring the total for Goeree-Overflakkee,<br />
which Deltawind is focusing on, to a capacity of<br />
225 MW. ‘We have completed this’, explains Deltawind<br />
Director Monique Sweep. ‘We will now target<br />
other parts of energy transition, such as collective<br />
solar roofs for private individuals. We will also be<br />
examining other forms of energy such as hydrogen<br />
and methane from seaweed, and storing energy at<br />
the Krammersluizen.’<br />
ZEEUWIND<br />
Citizens’ cooperative Zeeuwind will also focus<br />
on storing energy. Zeeuwind has been around for<br />
some 30 years, and back in the days we started<br />
with three wind turbines. The cooperative counts<br />
2,300 members, mainly private individuals. All of<br />
the 13 municipalities in Zeeland are members too,<br />
as well as several companies, associations, and<br />
foundations. The cooperative owns multiple wind<br />
farms, with a total capacity of 20 MW. Zeeuwind<br />
in the following years expects to double the total<br />
capacity with new projects and scaleups. An old<br />
turbine of one of the wind farms was replaced by a<br />
new one at the beginning of this year. This 2.3 MW<br />
turbine is expected to annually produce 3.9 million<br />
kWh. Zeeuwind also finances 25% of Windpark<br />
Bouwdokken, which is built on the dams of the<br />
former Bouwdokhavens on the Neeltje Jans production<br />
platform. These seven turbines have a capacity<br />
of 4.2 MW each, and have since early <strong>2018</strong> onwards<br />
jointly generated 112.5 million kWh of electricity<br />
per year.<br />
TWENTY-YEAR OLD PLAN<br />
Deltawind and Zeeuwind have already collaborated<br />
on a smaller scale, but the project on the Krammersluizen<br />
came into view in 2008. The cooperatives<br />
now together have 51% of the shares in Windpark<br />
Krammer. The remaining 49% is owned by turbine<br />
builder Enercon. The idea for the wind farm originated<br />
over two decades ago. According to Marten<br />
Wiersma, Chairman of the Zeeuwind supervisory<br />
board, the fact that it did not materialise back then<br />
is because the Rijkswaterstaat (Department of Waterways<br />
and Public Works), the owner of the land<br />
in those days, thought it was ‘a scary idea’ to build<br />
on top of a primary flood defence. ‘The wind turbines<br />
back then also had a capacity that was far too<br />
low, which made the grid connection far too costly.<br />
