Open Energy Day September 17

Cycle past sustainable energy projects in your area

Various sustainable companies will be opening their doors on 17 September this year so that you can see with your own eyes what a sustainable future looks like. And what is more fun than visiting the Open Energy Day organized by the Dutch Association for Sustainable Energy by bike? For those people we have designed a number of bicycle tours so you can see even more projects in one day and enjoy cycling through beautiful parts of the Netherlands.

The tours are not mapped out nor driven in advance. There may therefore be local detour due to, for example, road works. Check the opening hours before you set off, because they are not the same for every project. Have fun cycling and let us know what you think!

The solar park has 17000 solar panels that jointly produce a capacity of 4.75 MW, enough to supply energy to 1500 households. The entire solar park is dynamically controlled and supplies energy based on need, so there is never too much power supplied to the grid. The power is purchased by the brick factory in Azewijn. On this day we will give guided tours and present what is involved in building a solar farm. Sheep will be walking freely on the site and you can see how it has been fitted into the landscape.
