One of the largest solar parks in the Baltic region, featuring a solar tracking system, will be constructed near Marijampolė, in Kapsai. With a project value of €27 million, this development is led by UAB Wiso Engineering, the construction manager for energy projects owned by the Lithuanian-Estonian company UAB Evecon. The main contractor for the project is Lithuania’s RNDV Group.
The solar park is expected to generate approximately 52 million kWh of electricity annually, enough to supply over 12,000 households in Lithuania with clean, renewable energy. Covering an 86-hectare area, RNDV Group will install nearly 52,000 solar modules on a dynamic mounting system.
The variable-angle tracking system adjusts the tilt of the solar modules to an optimal angle, maximizing energy capture, especially during morning and evening peak hours when electricity prices are highest. This technology significantly increases energy yield compared to fixed-angle systems.
RNDV Group specializes in large-scale, technologically complex solar park projects across Lithuania and Western Europe, including France and Germany. In 2022, the company completed its first 10 MW park, followed by 90 MW in 2023, and plans to complete 250 MW of solar projects in 2024. Recent projects include a 5.3 MW rooftop installation in Germany, a 1.6 MW rooftop system at the Lidl logistics center in Lithuania, and ground-mounted solar plants of 17 MW, 13 MW, and 8 MW in France.
According to Aurimas Budrys, Head of RNDV’s Solar Construction Division, the project near Marijampolė is unique due to its tight schedule and winter construction timeline. “We’ll be completing a highly complex and large-scale project within just five months during the cold season. Given the client’s tight deadlines, we plan to complete major construction before the winter starts. We have assembled a team of 120 specialists, with whom we’ve successfully delivered similar projects in Western Europe,” says Budrys.
Vytautas Kieras, Head of the Lithuanian division of renewable energy company Wiso Engineering, says the Marijampolė solar park is their largest project in Lithuania. Wiso Engineering has already completed four solar parks in the country, including one in Panevėžys, one in Jurbarkas, and two in Varėna.
“Evecon’s ambitious goal is to develop one of the largest renewable energy portfolios in the Baltics. Over the next few years, we plan to install significant capacities of solar, wind, and battery parks across Lithuania, Latvia, and Estonia, exceeding 4 GW in total. Once the Marijampolė project is completed, the capacity of renewable energy facilities (solar, wind, and batteries) in Lithuania will reach 150 MW, and over 1 GW across the Baltic region,” Kieras explains.
Lithuania’s National Energy Independence Strategy aims to install 4.1 GW of solar energy capacity by 2030.
In 2023, RNDV group of companies revenue grew by 39%, reaching €105.4 million, while the total number of employees increased by 23%, from 1,300 to 1,600. The RNDV’s primary operations are concentrated in Western Europe, focusing on electrical installation in ships, data centers, shipbuilding and repair, electromechanical projects, scaffolding and technical insulation, and renewable energy projects. In the Lithuanian market, RNDV’s core activities are general construction projects, which saw a revenue increase from €11.3 million to €20 million in 2023.
