Energy, but better

Cactos is more than a company. We are a driving force in the energy revolution.

For centuries, the world has relied on fossil fuels. With the ongoing transformation, energy is becoming available everywhere.

However, the rise of renewable energy production and a rapidly electrifying society brings new challenges, such as dependency on weather. The need for grid balancing mechanisms is growing.

Our battery energy storage systems enable the shift to cleaner energy production and transportation by helping to balance supply and demand. At the same time, we help our growing customer base use energy better.

We combine bold innovation with top-tier expertise to accelerate the transition toward a more sustainable future.

A cactus adapts to its environment, has a thick skin and is a master of storing water and nutrients. With a little Ancient Greek spin on the name, Cactos was born.

Cactos Cardo

Energy and software experts had an idea

Cactos was founded in 2021 by a passionate team of energy and software experts in Northern Ostrobothnia.

While we established our headquarters in Helsinki, R&D and manufacturing remained in Muhos—the birthplace of our idea—until we moved to larger facilities in Kempele in the fall of 2024.

Designed and built in Finland

Our factory in Kempele reflects our commitment to unrivaled quality and Finnish craftsmanship. Here, leading-edge technology meets expertise, ensuring our products deliver top performance.

We constantly innovate to provide our customers with clean, sustainable, and flexible energy storage solutions for every business need—today and in the future.
