LST Group

What LST Group does

LST Group Oy is a privately held Finnish electrical engineering and services group founded in 1962 and headquartered in Turku, with approximately 220 employees operating from offices in Turku, Helsinki, and Rauma. The group is organized around three core subsidiaries: LST Marine (ship electrification and marine electrical products), LST Service (industrial maintenance, motor hotel/spare equipment services), and LST Talotekniikka (building services including HVAC/plumbing following the 2024 merger with Turun LVI-Tiimi Oy), with a further LST Transports unit serving rail, metro, bus, and defense vehicle electrification. Its product portfolio spans frequency converters, electric and gear motors, marine lighting, cable trays and penetrations, and EATON-branded UPS systems up to 1200 kVA, complemented by turnkey services covering design, installation, pre-manufacturing, commissioning, preventive maintenance, and remote monitoring.

LST generates revenue primarily through project-based professional services and equipment sales to enterprise and government customers in Finland and, for the marine division, internationally. Customer relationships include Meyer Werft, Siemens, VR Group, HKL, HSL, Finnish Defence Forces, DB Schenker, Hes-Pro, Röchling, and Rudus, with pricing delivered on a quote basis per project or multi-year contract; energy-mapping engagements can attract Finnish state subsidies covering 40-50% of approved costs. Distribution is direct enterprise field sales with no third-party channel partners, supported by service hubs that enable rapid 2-4 hour spare equipment delivery, and the company holds ISO 9001, ISO 45001, ISO 14001, and ISO 27001 certifications alongside Bisnode AAA and Asiakastieto Platinum credit ratings.

Go-to-market spans enterprise field sales for industrial and marine accounts, a dedicated defense/transport unit, and government procurement relationships for rail and public-sector buyers. Recent strategic activity centers on geographic expansion into Helsinki (2025-2026), the 2024 combination with Turun LVI-Tiimi Oy extending LST Talotekniikka into HVAC/plumbing, and a broadening into renewable and e-mobility adjacencies (solar, EV charging, battery storage via the WEG partnership, and a co-developed ESS battery fire suppression system).

Recent moves9 records

Expansion highlights6 records

Broad incumbents

• WEG: Brazilian global manufacturer of motors, drives, and battery energy storage. LST is a certified WEG partner in Finland; both sell motors, VFDs, and energy storage into industrial and marine customers.
• Wärtsilä: A global marine and energy technology leader headquartered in Finland. Overlaps with LST Marine in ship electrification and lifecycle services, but operates at vastly greater scale and as an OEM rather than an integrator.
• ABB Marine & Ports: Provides marine electrical propulsion, power, and automation systems globally. Comparable to LST Marine in vessel electrification and shore-power modernization, though ABB is a Tier-1 OEM across the full marine value chain.
• Eaton: Global power-management manufacturer and LST's principal UPS partner. Comparable because Eaton also offers marine-classified UPS, power distribution, and switchgear integration services that overlap with LST Marine and LST Service offerings.
• Siemens Mobility: Global rolling-stock OEM and integrator of rail electrification, also an LST customer. Comparable via the rail-vehicle electrification work LST Transports performs, though at incomparably larger scale and with proprietary train platforms.

Direct peers

• Bravida: Nordic multi-technical service provider delivering electrical, HVAC, and industrial solutions. Closely comparable to LST Group in vertical mix (industry + real estate + infrastructure), and competes for similar Finnish and Swedish contracts.
• Caverion: A large Finnish-headquartered provider of building technology and industrial services across the Nordics. Direct competitor to LST Talotekniikka and LST Service in industrial electrical installations, HVAC, and building electrification.

Others

• Meyer Werft: A major German cruise shipyard and direct customer of LST Marine for newbuilding electrical work. Peer in the sense that both deliver shipbuilding outputs, though Meyer Werft is the yard and LST is its electrical subcontractor.

Regional players

• Infranord: Nordic railway electrification and infrastructure contractor serving Sweden/Norway. Comparable to LST Transports on rail electrification projects, but focused on track-side catenary and signaling rather than vehicle-level work.
• Končar Group: Croatian electrical equipment and rail/marine systems manufacturer serving Central and Southern Europe. Comparable to LST's industrial/marine/rail verticals, but operating in adjacent rather than overlapping geographies.
