Enersense International Abp
Enersense International Oyj (also recorded under the Swedish-language designation Enersense International Abp and the English designation Enersense International Plc) is a Finnish public limited company with business ID 0609766-7, registered with the Finnish Trade Register in Pori. Finnish Patent and Registration Office (PRH) data show the business ID as assigned on 20 January 1986, while the company’s entry in the Trade Register (kaupparekisteri) was completed on 18 September 1986, a separate registration event. The company traded as a private limited company, Enersense International Oy, from 4 March 2009 until it converted to its current public limited form, Enersense International Oyj, on 14 February 2018. Its registered office is Konepajanranta 2, 28100 Pori, Finland, and PRH records its Trade Register status as active. PRH’s open-data record does not show the entity’s name for the period between its 1986 registration and the 2009 adoption of the Enersense International name, so earlier name history could not be independently confirmed for this profile.
Enersense International Oyj describes itself as a lifecycle partner for critical infrastructure, designing, building, maintaining and modernising energy and telecommunications infrastructure across the Nordic and Baltic region. According to the company’s own investor disclosures, its activities are organised into a Power segment (high-voltage transmission lines, wind and solar installations, substations, energy storage systems and data centres), Energy Transition Services (power plants, district heating networks, hydrogen facilities, hydropower plants, shipyard work and industrial piping and steel structures, plus consulting), a Connectivity segment (fixed and mobile network construction and indoor network installations) and Control Centre Services. PRH’s own Trade Register classifies the company’s main line of business simply as production of electricity from hydropower (TOL code 35121, effective 1 January 2026); this administrative classification is narrower than the diversified infrastructure-services activities the company itself describes and should not be read as a complete description of its operations.
Enersense International Oyj’s shares were admitted to trading on Nasdaq First North Finland on 24 April 2018 under the ticker ESENSE (ISIN FI4000301585), and moved to the official list of Nasdaq Helsinki on or about 14 June 2021. For the 2025 financial year, the company reported group revenue of approximately EUR 307 million and approximately 1,500 employees, according to its own investor-relations disclosures. The group has grown substantially through acquisitions in recent years, expanding both its service offering and its footprint in the Baltic states.
