NYAB approved for Fingrid’s class A supplier register for substation and transmission line projects
03.10.25NYAB is taking significant steps in its power grid business by being approved for Fingrid’s Class A supplier register for substation projects in May 2025 and transmission line projects in August 2025. This means NYAB will now participate in tenders for the most demanding 400-kilovolt (kV) substation and transmission line projects in Finland’s national grid – projects that are critical to the development of the country’s energy system.
NYAB Finland’s power grid business unit was established in March 2022. Already in September of the same year, the company was approved for Fingrid’s supplier register for 110 kV substation projects. In December 2022, NYAB was also accepted into the register for transmission line construction. The newly achieved Class A status in both categories opens the door to broader and more strategically important projects in Finland.
“Class A approval enables us to participate in 400 kV projects, strengthening our position at the heart of the energy transition. We can now deliver larger substation and transmission line projects and contribute to nationally important grid investments,” says Antti Keskinen, Head of Power Network Construction at NYAB Finland.
Renewable energy requires a strong grid
Renewable energy production in Finland is growing rapidly. According to statistics published by Renewables Finland (Suomen uusiutuvat ry) in June 2025, 85 new wind turbines were built in the first half of the year, with a combined capacity of 542.6 megawatts. By the end of the year, total wind power capacity is expected to reach approximately 9,400 megawatts. According to Fingrid, electricity production in Finland has surpassed 80 terawatt-hours, and by 2035, it is forecasted to reach up to 169 terawatt-hours.
Growth in wind and solar power is especially concentrated in Western and Northern Finland, increasing the need to strengthen and expand the national grid. Fingrid is also preparing for the first offshore wind projects in the 2030s. Solar power capacity has grown significantly, and by early 2025, it had reached approximately 1.2 gigawatts, according to Energy Authority (Energiavirasto).
NYAB at the heart of the energy transition
The construction of substations and transmission lines enables, for example, wind farms to be connected to the national electricity grid. Reliable power networks are also among the most important national competitiveness factors, especially in attracting investments in electricity-intensive industries to Finland.
Fingrid’s long-term grid planning continues to anticipate strong growth in domestic wind and solar power. NYAB’s approval for the Class A supplier register strengthens the company’s position in this development and enables broader participation in nationally significant grid infrastructure projects.
