What TSR-Elsite does
TSR | ELSITE Oy is a Finnish private limited company headquartered in Turku that develops, manufactures, and supplies temporary electrical, lighting, heating, and technology equipment for construction sites. The company's product portfolio covers five core categories — Työmaasähköistys (construction site electrification), Työmaavalaistus (lighting including the proprietary MBerg LED luminaire line with 48V safety variants), Työmaatekniikka (site technology), Työmaalämmitys (heating), and Generaattorit ja akkuvirtalähteet (generators and battery power sources) — and was broadened in July 2025 to include Staring pumps, construction dehumidifiers, and air purifiers. Its proprietary SPINE platform provides real-time remote monitoring and management of construction site electrical networks and has received EU funding for continued development.
The company serves professional construction companies and contractors on a B2B basis, with a publicly visible customer base that includes major Nordic contractors (NCC, YIT, SRV, Skanska, Consti, Luja) and equipment rental networks (Cramo, Renta). It was formed from the merger of EL & Site Oy and TSR Group Oy, and later added two Swedish entities, giving it a current footprint of three offices in Turku, Stockholm, and Malmö.
TSR-Elsite operates a multi-channel go-to-market: direct project sales with quote-based pricing, plus distribution through machine rental companies, distributors, and wholesalers. Revenue mechanics are dominated by one-time equipment sales and multi-year service contracts, with SPINE positioning the business toward an installed-base, recurring-monitoring layer over time.
