Freedom you generate yourself.
From consuming energy to generating it.
A building used to be a place where energy arrives and is consumed. It can just as well be the place where it is generated.
COR does not replace the grid. COR makes you less dependent on it: The heat and power plant generates heat and power, COR.stor stores electrical energy and the COR Platform controls the system.
- The building generates energy.
- It stores energy.
- It uses energy when it is needed.

What could your home save?
The calculator simulates your building for a full year in 15-minute steps, using the weather data for your region: heating, electricity demand, photovoltaics and storage. You see the result straight away, and can also download it as a PDF.

Energy when it matters most.
In winter, energy demand rises while photovoltaics deliver less. COR.set then generates heat and, at the same time, your own electricity.

This is COR in practice.
A completed installation, commissioned in 2026: three COR.stor units and three inverters, run together as one system.
Your energy is your freedom.
