What WEST Invest Group does

WEST Invest Group is a privately held, family-owned Finnish industrial conglomerate headquartered in Kerava, Finland, founded in 1959 (originally as Höyrytys) and currently led by CEO Harto Viiala of the founding Viiala family. The group operates through seven wholly-owned subsidiaries — Höyrytys Oy (steam and mobile backup energy services), Hyxo Oy (water treatment engineering and process measurement), Ubitec Oy (industrial electrification and instrumentation), Enico Oy (battery energy storage systems and AI-assisted reserve-market trading via EnicoEMS), Ekomuovi Oy (custom plastic tanks and dosing systems), KMV-tuotteet Oy (water pumps and treatment equipment distribution), OleiniTec Nordic AB (Nordic measurement technology), and Sakutek Oy (electrical and automation solutions) — collectively delivering water treatment, energy, and technology solutions to industrial clients (forest products, food and beverage, process industries, energy sector) and municipal/government customers across Finland, with limited Nordic reach into Sweden.

The group's technology stack spans industrial water and wastewater treatment, steam and hot water boiler systems, electric boilers, mobile backup energy plants, battery energy storage systems with proprietary EnicoEMS multi-market optimization software, and full electrical/instrumentation project delivery for process and energy industry facilities. Notable technical integrations include Danfoss iC7 Hybrid power converters in Enico storage products (achieving over 75% European technology content) and Valmet process measurement instrumentation in Hyxo's wastewater portfolio.

The business model combines project-based equipment and turnkey delivery revenue (water treatment plants, boiler plants, BESS, electrification packages) with recurring service and maintenance contracts and monthly fee-based standby energy agreements with district heating companies. Customer relationships are anchored by long-tenure standby contracts (e.g., 24/7 10 MW backup for Keravan Energia, 7.5 MW for Tampereen Energia), multi-year maintenance agreements, and marquee project wins (Metsä Fibre Kemi bioproduct mill, Stora Enso 60 MW electric boiler, Keliber lithium refinery). All sales are direct via subsidiary sales engineers and project managers with no reseller or distributor channels. The company is described as 'strongly growing,' was recognized on Deloitte Technology Fast 50 in 2023 and 2024, and currently employs 101-250 staff plus subcontractors across multiple Finnish offices and one Swedish office.

• Wärtsilä: Finnish energy technology provider with strong presence in flexible power, energy storage, and grid balancing. Comparable to Enico's BESS and reserve market business, though operating at much larger scale globally.
• Kemira: Finnish water chemistry and treatment specialist serving municipal and industrial water customers. Comparable to Hyxo and KMV-tuotteet water treatment operations but at significantly larger scale and with a chemicals-led model.
• AFRY (formerly Pöyry): Finland-headquartered engineering and design consultancy with strong forest, energy, and water practices. Comparable to WEST Invest Group's project delivery model in industrial water and energy infrastructure, though AFRY is consulting-led rather than equipment-led.

Others

• Danfoss: Power electronics and drives manufacturer supplying Danfoss iC7 Hybrid converters into Enico's energy storage systems under a 2025 framework agreement. Component supplier and strategic technology partner rather than direct competitor.
• Bollegraaf: Dutch recycling equipment manufacturer partnered with Ubitec for Nordic installation and maintenance. Adjacent player addressing recycling automation; partnership strengthens Ubitec's reach into environmental services adjacent to its industrial electrification base.
