Tetas

What Tetas does

Tetas (legal entity: UAB "Tetas") is a Lithuanian electrical engineering and infrastructure services company founded in 2005 and headquartered in Kaunas, with five additional regional offices across Lithuania (Panevėžys, Vilnius, Alytus, Šiauliai, Klaipėda). The company is wholly owned by EPSO-G, the state-owned energy holding company under the Lithuanian Ministry of Energy, which makes Tetas an instrument of national energy policy, particularly Lithuania's grid synchronization with continental Europe and renewable integration programs. Tetas provides a full lifecycle of high-voltage electrical infrastructure services spanning the 0.4-400 kV range, including design, construction, reconstruction, maintenance, relay protection and automation (RAA) commissioning, teleinformation (TSPĮ) systems integration, and a nationally accredited high-voltage laboratory for equipment testing, transformer oil analysis, and metrological verification.

The company serves primarily Lithuanian and Baltic transmission system operators (notably Litgrid and Latvia's AST) and distribution system operators (ESO), with additional international engagements including Ørsted (Denmark wind farm), Verbund Hydro Power (Austria), Siemens Energy (synchronous compensators), and renewable developers such as Green Genius and FutureEnergy. Recent contract activity has been dominated by grid synchronization projects, substation reconstructions (Berčiūnai €2.8M, Subačius €2.3M), 330 kV transmission line work, and entry into utility-scale battery energy storage (a 56 MW / 168 MWh BESS in Raseiniai). Tetas also operates construction equipment rental and surplus asset sale businesses, and in 2024 secured representation rights for Maschinenfabrik Reinhausen GmbH in the Baltic states. Revenue is generated through project-based public procurement contracts (primarily via the deallink.biz platform) with state-owned utilities, with pricing negotiated per project and no public revenue disclosure.
