About us

We develop, build, finance, and control energy storage systems that make Europe more stable.

Since 2017, wattss has been implementing battery storage projects that stabilize grids, relieve industry, and make renewable energy usable—in Switzerland, Germany, and Finland.

Our conviction

wattss stands for European technology, security, and data sovereignty—because energy is the new strategic infrastructure of our continent. We combine engineering, software, operations, and financing into a platform that makes energy manageable. And we deliver impact today: real projects, real stability, real results.

4 Pillars

Technology

Our facilities are located where they are needed: in industrial plants, commercial parks, and grid nodes. They store energy when abundant and deliver it when Europe needs it most urgently.

Intelligence

Smart digital management transforms individual storage units into a coordinated, learning overall system. It optimizes performance in real time, protects against cyber risks according to European standards, and keeps energy flows under precise control.

People

Well-trained and motivated employees as well as strong partners implement our vision. Technology works—because there are people behind it who understand it.

Capital

Sophisticated investment and financing solutions make storage projects feasible: fast, structured, and reliable. Financing does not become an obstacle, but an accelerator.

wattss consistently relies on European manufacturers, security, and supply chains. Because energy is the new strategic infrastructure of our continent—and Europe must hold it in its own hands.
