A solar photovoltaic park with a capacity of 330 MW is being developed in Jonava, Lithuania.

Engineering firm DS1 said that the installation will be the biggest photovoltaic park in the Baltic states. At this scale, the project stands out not only within Lithuania but across the entire Baltic region, where solar developments of comparable capacity have not previously been announced.

Jonava Project Marks Major Expansion of Baltic Solar Capacity

The 330 MW figure places the Jonava project in a category of its own among Baltic solar initiatives.

A park of this size represents a substantial addition to the region's renewable energy generation portfolio, and its positioning in Jonava signals the growing role of Lithuanian territory in the Baltic solar build-out.

DS1: The Company Behind the Coverage

The project is featured by DS1, a Lithuanian engineering and construction company headquartered in Vilnius.

UAB DS1, registered under company code 181123848 and VAT number LT811238412, maintains offices at Kauno str. 22 in Vilnius and at Lyderystės str. 7 in Biruliškės. The company operates a bank account with AS Citadele banka.

DS1 describes quality as a defining feature of its operations, stating that "excellence isn't just a goal, it's the standard that drives everything we do" and that the company is "committed to delivering superior quality in every project, ensuring our clients receive nothing but the best."

Certified Across Multiple Standards

The company's quality credentials span a wide range of internationally recognized management systems.

DS1 holds ISO 27001:2022 certification for information security management systems, ISO 9001:2015 for quality management systems, and ISO 14001:2015 for environmental management systems. Occupational health and safety management is covered under ISO 45001:2018, while energy management is addressed through ISO 50001:2018 certification.

In addition to management system standards, DS1 carries ISO 3834-2:2021 certification, which covers quality requirements for fusion welding of metallic materials, a technical qualification relevant to fabrication and metal construction work. The company also holds VERT LT certificates and an SPSC construction production certification center credential.

Beyond its certifications, DS1 is a member of IPLOCA, the International Pipeline and Offshore Contractors Association, and carries the Achilles Supplier Stamp, indicating participation in supplier qualification schemes relevant to industrial and energy sector procurement.

What the Project Represents

The prominence given to the 330 MW Jonava Park in DS1's news communications underscores the scale of the undertaking.

Solar parks in the tens of megawatts have typically represented the upper tier of Baltic renewable development; a project four to ten times larger than many regional installations marks a step change in ambition.

The designation "largest PV park in the Baltics" sets the benchmark against which other regional solar developments will now be measured.

While the full technical details of the Jonava park, including its developer structure, timeline, and grid connection arrangements, are not elaborated, the headline figure of 330 MW and the Baltic-first designation communicate the essential scale of the project.

Further project information can be directed to DS1's contact channels.

A Track Record in Large-Scale Infrastructure

DS1's portfolio and service offerings, accessible through its website, position the company within the large-scale infrastructure and energy construction sector.

Its membership in IPLOCA, an association focused on pipeline and offshore construction, alongside its welding quality certification, suggests a company rooted in heavy industrial construction whose activities extend to renewable energy projects such as the Jonava solar park.

Context for Baltic Solar Development

The emergence of a 330 MW single-site solar project in Lithuania reflects the trajectory of solar development across the Baltic states, where renewable capacity targets have driven increasingly large installations.

Jonava, located in central Lithuania, now hosts what its developers describe as the region's largest PV park, a title that, if confirmed upon completion, will mark a milestone for the country's energy sector. As stated in the project's announcement, the park's 330 MW capacity is the defining statistic.

For an industry audience tracking Baltic renewable energy build-out, the Jonava project stands as the reference point for utility-scale solar in the region, and DS1's coverage of the initiative signals the company's role in delivering projects at this scale.
