VSV Group

What VSV Group does

VSV Group (legal parent Vakka-Suomen Voima Oy, headquartered in Laitila, Finland) is a privately held regional multi-utility energy group serving the Vakka-Suomi area of southwestern Finland. Established in 1969 and operating across wholly-owned subsidiaries VSV Sähköverkko Oy (electricity network, spun off 1 June 2025), VSV-Energia Oy (energy sales and district heating), Vertek Oy (electrical contracting and industrial electrification), and related entities Laitilan Lämpö, APT-Enertel Oy, and Satavakka Oy, the group transmits approximately 400 GWh of electricity annually, produces and distributes district heating in Laitila and Uusikaupunki (99.01% delivery reliability), and delivers contracting and industrial services.

Its core technology stack combines a 750 km medium-voltage electricity network (with ≈160 Safegrid wireless sensors deployed for partial-discharge and predictive fault analytics, and ~52% underground cabling targeted to reach 70% by 2036) with two AI-featured district-heating products: OptiLämpö (AI-based heating optimization for housing companies with weather-forecast integration and demand-peak cutting) and AitoLämpö (100% origin-certified heat for corporate sustainability reporting). The customer-facing Oiva Online self-service portal handles electricity contract management, consumption monitoring, and invoicing.

Revenue is generated through four primary streams: regulated electricity network fees (perusmaksu and siirto charges under Energy Authority oversight), district heating tariffs in Laitila and Uusikaupunki, business energy services (OptiLämpö, AitoLämpö, industrial electrification), and professional services contracting via Vertek Oy (an estimated ~30 million EUR segment). Customer segments span residential consumers, housing companies, industrial and commercial enterprises (e.g., Valmet Automotive, Kivikylän Lihanjalostus), electrical contractors, and agricultural customers transitioning from oil heating. Distribution is direct (phone customer service, physical offices, Oiva Online portal) and via Vertek contracting plus the associated electricity retailer Omavoima. The group employs 101-250 people and continues to invest in infrastructure hardening, electrified heating, and digital services.
