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 />
