About NextEnergy

Energy can be different. Fixed contracts with high cancellation fees are outdated, just like the energy giants charging sky‑high margins. At NextEnergy, we do things differently. Our users always pay the actual market energy prices. When the sun is shining or the wind is blowing, they save extra by doing laundry or charging their car at just the right moment.

And that’s just the beginning. We want to give everyone in the Netherlands back control over their energy bill. Not only with competitive rates, but also with smart solutions. Through our app, users can automatically charge their electric car when electricity is cheapest, or even purchase a smart home battery.
