Green Genius Expands Capacity in Latvia: Battery Energy Storage System Commissioned 

At Green Genius’ 120.8 MW solar park in the Jēkabpils region of Latvia – the largest single-site solar park in the Baltic states – a 25 MW / 100 MWh battery energy storage system (BESS) has commenced commercial operations. Equipment for the second development phase is already arriving on-site, which will double the system’s power and energy storage capacity to 50 MW / 200 MWh. 

Deploying a battery energy storage system at the 120.8 MW solar facility makes it one of the region’s largest independent flexible generation hubs. The first-phase 25 MW / 100 MWh system is now commercially operational and connected to the electricity transmission grid. The delivered second-phase battery modules and power inverters will double capacity in the near future, allowing it to store surplus solar power during peak production and discharge it during peak demand, or provide essential frequency response and grid-balancing services. 

“In the renewable energy sector, expanding generation capacity alone is no longer sufficient – generation control and flexibility have become decisive factors. The operational solar park in Jēkabpils, integrated with the battery storage system, directly addresses transmission grid constraints and generation intermittency. Delivering the second-phase equipment and expanding capacity to 50 MW / 200 MWh will maximise infrastructure utilisation, deliver stable returns, and provide the grid services required for the independent operation of the Baltic power grid,” says Ruslan Sklepovič, CEO of Green Genius. 

Energy Storage and Hybrid Projects in Lithuania 

The Jēkabpils project advances Green Genius’ ongoing strategy to develop large-scale hybrid energy hubs combining renewable generation with utility-scale battery storage. In Lithuania, the company already operates and develops a substantial storage portfolio:
