What do an airport in Hungary, an hospital in Northern Ireland and a waste water treatment centre in Malaysia have in common?

They have all turned to Finland’s Merus Power to save energy, increase productivity and capacity and reduce energy costs.

Merus Power offers clean technology to improve power quality, energy efficiency and environmental performance.

Although multinational companies operate in the same business area, managing director Kari Tuomala says Merus Power can offer a tailor-made service.

— We have selected our market niche in power quality and we put all our efforts into that particular problem so we have a specific know-how and good problem-solving capabilities.

Underwater mining

Merus Power operates in a variety of sectors including wind and solar, mining oil and gas, textiles and data centres.

The solutions it offers range from stabilizing voltage to mitigating harmonic distortions. Harmonics are electric voltages and currents on an electric power system, which can cause power quality problems.

One recent project, which exemplifies how the company operates, was for the underwater diamond mining operations for De Beers off the coast of Namibia.

The project was initiated by a local partner as Merus Power always works with local partners abroad.

Engineers were reporting that the variable speed drives operating the pumps used for drenching were causing high harmonic distortions – high enough to result in the overload of the whole electrical system.

Merus Power shipped a filter to South Africa to coincide with the vessel’s dry docking schedule in Cape Town.

Nine months since the device was installed, harmonic distortions have been reduced to virtually nil and mining operations are now running smoothly at the vessel without any unexpected and costly disruptions.

Rapid growth

Merus Power has enjoyed rapid growth in recent years. Last month, the Deloitte Technology Fast 50 programme, which lists the fastest growing technology companies in Finland, ranked it fourth on its Rising Star list. Revenues have grown 571 per cent over the last three years.

With investments in research and development now bearing fruit, the company is focusing increasingly on global expansion and sales. Turnover was three million euros in 2013 and is expected to be nearly five million next year. Merus Power is chasing a five- to tenfold increase by 2017-18.

“Now is the time to get the brand recognized and establish long-term customer and partner relationships,” says Tuomala.

The company is also pinning its hopes for new business on a patented system it has developed, aiming at protecting emission critical processes from voltage dips and power failures for a short period of time.
