Power from the wind

For us power from wind is a key enabler to fulfill our vision of becoming the leading producer and seller of Co2 aware energy, and we have the competence to operate along the full value chain for wind power.

What we do

We have over ten years of experience in the wind power industry. Already in 2009 St1 co-founded a company called TuuliWatti Oy together with S-Voima and we have developed and built more than 500MW in the Finnish Market. St1’s share of Tuuliwatti was later divested to Exilion Tuuli, but remains under St1 one operatorship. As of 2024, we operate 3.5% of total Finnish wind power, making us one of the largest third-party operators of wind farms in Finland.

We are aiming to grow our service portfolio further also with new customers. For St1, wind power is integral to our vision of becoming the leading producer and seller of CO2-aware energy. We work with our own value chain which already today is selling renewable energy to our core customer segments, and we aim to enable the transition away from fossil energy by providing the low-cost clear energy to our value chain and that of others.

In line with our aim we are currently developing several projects in Norway and Sweden. Read more here: 

What we do:

  • Development management according to St1's sustainability framework
  • Social License and Stakeholder management
  • Construction management with high HSSE and sustainability standards
  • Technical and Commercial Management (TCM) according to customer's specific needs

Some of our projects are operated by us, but we also partner with others or provide service on demand. Our expertise covers managing the entire value chain, from acquisition of project rights and project development, to financing, engineering, procurement and construction, and further on to Technical and Commercial Management (TCM).
