Where power is critical

"Critical" means something different in every sector.
The sites themselves answer which.

01 Aviation and transport hubs Terminals never pause. Neither do their electrical systems. Vilnius Airport · T4 departure terminal 02 Defence infrastructure Extreme urgency, sites with the highest reliability and security requirements. Rheinmetall plant, Baisiogala · Rūdninkai military town 03 Biotech and cleanrooms Once a laboratory is commissioned, even the smallest mistake can cost a complete refit of the whole lab. Thermo Fisher Scientific · BIO CITY / Celltechna · Metrosert in Estonia 04 Industry and process infrastructure If a production line stops, what is counted is not minutes but the cost of downtime. Jonavos Grūdai · Continental · Kauno Grūdai 05 Energy infrastructure First we calculate how power should move. Then we build. Baltisches Haus solar portfolio · EV networks: Ignitis, Eldrive, Inbalance
06 Data centers and connectivity When power fails here, connectivity fails for thousands. That is why supply and redundancy are the very first question. Baltneta data center · internet network infrastructure
DEFENCE

We are delivering on Lithuania's largest military sites.

INDUSTRY AND PROCESS INFRASTRUCTURE · JONAVOS GRŪDAI

When power stops, more than motors stop.

At one of the largest grain elevators in the Baltics, the harvest peak is a time of overload — farmers queue to deliver grain, systems run at the limit, and the smallest electrical fault stops the lines and clogs the whole conveying system with product inside. It has to be cleared by hand and restarted. Meanwhile, the farmers drive off to deliver their grain to a competitor.

A month of preparation + a weekend of work = a new supply.
FRIDAY

Old supply switched off.

WEEKEND

Dismantling, new substation, switchboard, cabling, testing.

MONDAY

Production runs on the new system.

When power stops, more than motors stop.

A month of preparation, one weekend of work — on Monday the elevator runs from a new substation. See how.

02 · CAPABILITIES

Six capabilities.
One team.

We can design, manufacture, install and maintain every element of the chain — so responsibility never gets lost.

01 Design From grid connection to full integration. BIM, Dalux, Trimble. → 02 Building electrical infrastructure The design changes. The deadline doesn't. → 03 Outdoor electrical networks ESO grid, fast-track connections, EV parks, underground infrastructure. → 04 Switchboard manufacturing Own facility in Vilnius. Factory-tested before dispatch. → 05 Power quality We measure first. Then we choose the equipment. → 06 Maintenance and response We often arrive to fix one problem. We stay to maintain the whole system. →
HOW WE WORK

One project — one team.

A project manager, a site manager, foremen and a designer — assigned to one site, with the authority to decide on the spot. That is how we handle projects with a lot of integration, coordination and change.
