At Wärtsilä, Business Intelligence Analyst Arttu Pyysing is doing something he cares deeply about: advancing the energy transition.

“I don’t want to glorify my job – I am not planting trees in the desert – but I am trying to do something tangible to mitigate climate change. It is my job to construct insights that help accelerate the energy transition,” says Arttu Pyysing.

Pyysing started work as an analyst in Wärtsilä Energy’s Business Intelligence team in early 2022, after graduating from Aalto University in Finland, where he studied finance, economics, and data analytics, along with some IT and accounting.

Upon graduating, Pyysing had a clear idea about the kind of career he wanted to build.

”I worked in several companies alongside my studies. Although I had interesting tasks and wonderful co-workers, I wanted to do something with my time that I perceive meaningful,” he underlines.

Advancing the energy transition

After self-reflection, Pyysing decided to apply for a job in the energy sector.

”I am passionate about fighting climate change. I remember one course in particular during my master’s studies: Energy and Environmental Economics. It really got me thinking about the energy sector and the difference that it is making,” Pyysing says.

“Wärtsilä caught my interest because it has a very concrete role in advancing the energy transition. It is developing technologies that support the transition towards a renewable energy future. I decided to apply for a position at Wärtsilä Energy where I could put my skill set to the best use,” he adds.

I am trying to do something tangible to mitigate climate change.

Pyysing underlines that Wärtsilä’s flexible and scalable balancing solutions are crucial enablers of the energy transition:

“To understand why Wärtsilä’s role is so essential, you have to look at the big picture. When you use renewable energy on a large scale, you must have balancing solutions that can quickly ramp up and provide power, for example balancer gas engines and energy storage systems. It is the only way to keep the grid stable whenever renewables like solar or wind power aren’t generating enough electricity,” he remarks.

“Wärtsilä’s engines can have large net impacts on clean energy, because they allow much more renewable generation,” he adds.

The right information helps make the right choices

At Wärtsilä, Pyysing conducts market analyses in the Business Intelligence team, together with internal and external collaborators.  

“At present, Europe is not winding down coal-fired power plants as fast as planned due to the war in Ukraine – but I am quite hopeful that as the dependence on Russian energy supplies are decreased in accordance with the REPowerEU (, energy transition will accelerate substantially within the next 5–10 years,” Pyysing says.

”Most analysts concur that the current situation has already noticeably improved the prospects of green hydrogen – fast-tracking projects is essential for Europe,” he adds.

Pyysing asserts that his job gives him a sense of purpose:

“When people have the right information at the right time, they can make the right choices to advance the energy transition. It is my job – as part of our team – to ensure that this information is readily available,” Pyysing describes.

”As an individual, there is only so much you can do to mitigate climate change. But in my line of work, I know that I am using my working hours to try to advance the energy transition, decarbonisation, and the use of renewable energy,” he concludes.
