What Enerke does

Enerke Oy is a Finnish privately-held electrical infrastructure services company headquartered in Lehmo, Joensuu area, that designs, constructs, and maintains electricity distribution and transmission networks, electrical substations, data and fiber optic networks, street lighting networks, and backup power solutions for utility operators, industrial customers, telecommunications providers, and municipalities. The company operates 17 locations across Finland with approximately 281 employees (2025), including a dedicated substation design office in Nokia, and executes turnkey projects through competitive tendering across voltage levels from 0.4 kV to 400 kV. Its customer base includes Finland's transmission system operator Fingrid (where Enerke holds A-supplier status for 400 kV substations since July 2025), major distribution system operators Caruna, Elenia, Savon Voima Verkko, PKS Sähkönsiirto, regional utilities, telecom operators BLC Telecom and Karelnet, industrial players such as Metsä Board and Tervakoski, and municipal clients including Kitee.

The company's core technology is the integrated delivery of electricity infrastructure lifecycle services: substation engineering (design through commissioning), overhead and underground cable construction at all voltage classes, protection and automation systems, fiber optic network roll-out, and complementary street lighting and emergency backup power services. Enerke differentiates through its own design and structural engineering capabilities, its certified management systems (ISO 9001, ISO 14001, ISO 45001, ISO 27001, plus RALA construction quality and environmental certifications), and a workforce developed over more than two decades of cooperation with Finnish educational institutions (recognized as Trainer Company of the Year 2023). The substation business unit alone generated €25M of revenue in 2024, delivering 16 larger substation projects across the country.

The business model is project-based professional services revenue generated through competitive tendering for enterprise and government clients, supplemented by recurring maintenance and service contracts. Pricing is not publicly disclosed and is quote-based per project scope. Projects span from design-only engagements to full turnkey (avaimet käteen) deliveries covering planning, construction, and commissioning. All customers are B2B: no consumer-facing distribution or product sales. Revenue concentration is in enterprise-scale infrastructure projects for a small set of large regulated buyers, with the customer base spanning regulated transmission, regulated distribution, industrial electrification, telecom fiber, and municipal lighting segments across Finland.

Scale indicators6 records

Recent moves7 records

Expansion highlights6 records

Broad incumbents

• Siemens Energy: Global OEM of high-voltage substations, switchgear and grid automation systems. While not a like-for-like EPC contractor, Siemens Energy competes for supply and commissioning scopes within the same Fingrid 400 kV and DSO 110 kV projects that Enerke executes.
• Rejlers: Nordic engineering and technical services consultancy active across power transmission, distribution and substation design. Overlaps with Enerke's in-house design and engineering capabilities (Nokia substation design office) and competes for technical scopes on similar utility projects.
• AFRY (formerly Pöyry): Nordic-headquartered engineering, design and project management consultancy with a strong Finnish power-grid practice. Overlaps with Enerke on design, planning and owner's-engineer scopes for the same grid-operator customers and substations.
• ABB: Global provider of substation equipment, protection and automation systems used in Finnish 110 kV and 400 kV projects. ABB supplies key components Enerke integrates into turnkey substation deliveries and is a competitor for parts of the value chain.

Emerging players

• Aarsleff Ground Engineering: Northern European specialist in foundations and cable/pipe installation that participates in power-line undergrounding and substation groundwork. Comparable to the civil/earthworks side of Enerke's offering rather than the full turnkey electrical delivery.

Direct peers

• Voimatel: Finnish electrical network contractor offering design, construction and maintenance services for distribution and transmission networks. Operates in the same competitive set as Enerke for Finnish DSO tenders and shares the customer base of regional grid operators.
• Empower IM: Finnish electricity network and substation services provider serving DSOs, TSOs and industrial customers in Finland. Directly competes with Enerke for the same Finnish grid-operator tenders and has comparable capabilities in substations and network construction.
• Netel: Nordic infrastructure services group active in electricity, telecom and fiber networks, with significant presence in Finland. Competes with Enerke on fiber optic, telecom and electricity-network construction projects for similar utilities and telecom operators.
• Eltel Networks: Nordic-based, publicly listed infrastructure services company specializing in electricity distribution, transmission and substation build/maintain across the Nordics, Baltics and Poland. Closest direct peer to Enerke in scope (substations, T&D networks), customer base (DSOs/TSOs) and geography (Finland is a key market).

Regional players

• OneCo: Norwegian infrastructure services company delivering power-line, substation and telecom network services primarily in Norway, with Nordic overlap. Comparable in service portfolio (T&D, substations, fiber) to Enerke but operating in a different national market.
