Hoppenbrouwers and Bakker Sliedrecht help Amsterdam water company become climate neutral

04 March 2020

Hoppenbrouwers Techniek and Bakker Sliedrecht will install three solar parks for an Amsterdam water company. The third in this cooperation, solar field Nieuwegein, has over 17,000 solar panels with a capacity of 5,5 megawatt peak of power. The solar field will be completed before the summer period.

Specialist in renewable energy Hoppenbrouwers will install the solar panels, inverters and transformer stations. High-voltage specialist Bakker Sliedrecht will convert the 400 volts of the solar park into 10 kilovolts and will ensure the connection to the 10 kV-grid of the water company. “Together we complement each other as a team and we have the expertise to install and connect complete solar parks,” says project coordinator Koen van Ostaden of Hoppenbrouwers and high-voltage specialist Nico IJzerman of Bakker Sliedrecht.

The water company supplies drinking water and treats waste- and sewer water for the Amsterdam region. The company collects water from the Lekkanaal (Lek-channel) near Nieuwegein and the ‘Bethunepolder’ near Maarssen and has it pre-treated in a natural way in the ‘Amsterdamse Waterleidingduinen’ and in the ‘Loenderveense Plas’. The solar parks are intended to provide electricity for the purification of both drinking and sewage water.

Besides the solar field Nieuwegein Hoppenbrouwers and Bakker Sliedrecht will install two other solar parks for the Amsterdam water company in Loenderveen and Weesperkarspel. Hoppenbrouwers previously installed various solar parks, including three sewage treatment plants for the Amsterdam water company. Bakker Sliedrecht entered the solar market last year, when it connected its first solar park in Moerdijk. That called for more. “In itself, connecting a solar park is not very different compared to other high-voltage connections,” says IJzerman. According to Van Ostaden, the cooperation is successful because the specialisms of the two companies complement each other very well. “Simply put, we do all low voltage and Bakker Sliedrecht all high voltage,” he says.

Over the past hundred years, Hoppenbrouwers Techniek has grown into a modern installation company. As an all-round installer the company designs, installs and maintains electrical and mechanical installations. Bakker Sliedrecht also celebrated its centenary last year. Over the past century, the company has become one of the largest independent electrical system integrators in the world. The two companies have been working together on several projects for decades. Recently at a bus depot in Utrecht and a hospital in Tilburg. During these projects, Hoppenbrouwers acts as the main contractor and Bakker Sliedrecht is called in for its expertise in the field of high voltage.
