How Stekker helps to stabilize the grid

The success of clean energy has caused recent peaks of energy flowing onto the grid.

That's a problem, because the grid always needs to be perfectly balanced. If too much electricity flows onto the grid, things can start to heat up and fail.

By storing these peaks of solar and wind power in the batteries of cars, we can help to lower the load on the grid and allows more clean energy to be used instead.

While saving costs for everyone.

Works perfectly for Skoda Enyaq IV60. Used the "Stekker" app for the first time in combination with my (home) charging station "Wallbox Pulsar Plus". It stopped a few times and then automatically resumed charging after a while. Saved 1.08kg and CO2 €0.54!! Awesome!! The is visually stunning and easy to use. Compliments!!!


Apple App Store Review

Super convenient and clear app if you want to smart charge your electric vehicle. With the Tesla Model 3 connected, you can see when the car starts charging and at what cheap energy rates. Recommended if you want to charge more cleanly and cheaply!


Google Play Review

This is a fantastic app that allows you to charge more sustainably and cheaply, giving you not only a good feeling but also actual cost savings. Stekker also regularly updates the application with new and fun features, and the app is very user-friendly. You can easily see a nice graph showing when the car will start charging at the cheapest time.
