Festival powered by wind and solar energy

Rock Werchter in Belgium has been committed to becoming a more sustainable festival for years. To minimise diesel consumption this year, the organisers tried something new: a combination of wind, solar, grid power, and batteries.

Bolt Energie provided an innovative mobile wind turbine. Positioned at the entrance of the festival grounds, its 20-metre height and colourful design drew a lot of attention. The wind in its blades generated up to 110 kWh of green energy per day. Close by, there was a field of solar panels covering 1800 square feet, generating between 150-200 kWh per day. These are two excellent methods for generating sustainable energy, but one more component was needed to truly optimise these energy sources. Well, actually, three.

Smartly combining power sources

We connected three 422 kWh Greener batteries to the grid, creating a microgrid together with the wind turbine and solar panels. The batteries stored the wind and solar energy directly, to be used later during peak moments. Think of big performances on stage or busy times at the food and beverage stands. With this setup, the festival could even run at night solely on solar power.

Rock Werchter demonstrates that with an open mindset and the integration of various innovative technologies, anything is possible! Even without a grid connection, you can power your festival emission-free. You can even have a quiet, sustainable power solution for events in cities or protected nature reserves. Here’s to a fully emission-free festival, everywhere.
