Between 2017 and 2019, we toured dozens of properties in the Helsinki metropolitan area and examined their main centres. We quickly noticed that the world had changed and the electricity grid could not keep up.
When the electricity grid can't keep up
LED lighting, power electronics, solar panels and electric car charging had changed the load. The reactive power turned more and more often to the capacitive side and the current became distorted. The old compensation solutions no longer worked properly in this new environment. In addition, they require annual and expensive maintenance.
We asked ourselves: Could this be done better?
2021 –
In 2021, we started the development of a new type of device in cooperation with our Italian partner, Energia Europa S.p.A. We had been working with them for almost ten years, and now we have combined our expertise.
The result was OTSOSMART – a basic model that corrects the reactive power and power factor to the desired value in microseconds, with extreme precision. At the same time, it balances the diagonal load in the direction of the network company.
But we didn't stop there...
OtsoPro and OtsoMax
The next phase of the development work brought with it two new models: OTSOPRO and OTSOMAX. • OTSOPRO filters low-frequency harmonics (3–13). • OTSOMAX goes even further – it filters out all harmonics (3 to 51).
This means that a single family of devices can solve problems that previously required several different systems.
"It's great that you no longer have to put one plaster on top of another, but the power quality is fixed with one device."

Today, our customers are cities, municipalities, industry, water utilities, data centres and office sites all over Finland. Our equipment is also sold by Onninen Ltd and Keravan Energia Oy together with OtsoSmart Oy.
Our story continues, but its core has remained the same from the beginning: to solve a problem for which the old methods are no longer enough.
