Carelin Oy

What Carelin Oy does

Carelin Oy is a Finnish private limited company headquartered in Seinäjoki, founded in 2017, that provides specialist technical consulting and engineering services to the renewable energy sector. Its service portfolio spans the full project lifecycle of wind, solar, and battery storage assets, including owner's engineer (OE) services, Technical Management Agreement (TMA) operations, project management, construction supervision, preliminary studies and preparation, and end-of-warranty inspections. Customers are large Nordic energy operators, developers, and institutional asset owners — publicly identifiable clients include Taaleri Energia, S-Group entities (S-Voima and Gigawatti), Exilion, and CPC Finland Oy — with mandates covering projects such as the Eurajoki 80.6MW wind farm (13 turbines), the Paistinkulma 30MW/36MWh battery storage project in Lempäälä, the Rauma 32MW solar plant, and the Sipoo 2 MWp logistics-centre solar plant.

The underlying technology is human-delivered engineering expertise rather than a software platform; the firm brings specialized domain knowledge across solar PV, onshore wind, and utility-scale battery storage, supported by practical project-execution experience that is repeatedly cited as its core differentiator. There is no proprietary software product, and no AI/ML capability is referenced in the available data. Pricing is not publicly disclosed, and revenue is generated through bespoke professional-services engagements rather than productized or subscription offerings.

Carelin's revenue model is B2B professional services delivered through direct enterprise relationships. Distribution is via direct client engagement and relationship-based selling, with no public marketing or channel infrastructure referenced. On March 1, 2024, Carelin was acquired by AFRY, an international engineering and design company, and now operates as an integrated unit within AFRY's energy sector, leveraging AFRY's broader Nordic and international delivery network for renewable energy projects. The firm has 11–50 employees based on current firmographic data.
