Latvia’s largest single-site solar plant begins operating
The 120.8 MW project, built by Lithuanian renewables developer Green Genius, is the largest single-site project in the Baltics. Work is currently underway on constructing a 50 MW/100 MWh battery energy storage system on-site.
Made in Europe: Sungrow builds first European factory in Poland
Sungrow says it plans to invest €230 million ($274 million) in its first European factory in Wałbrzych, Poland, to produce inverters and battery energy storage systems (BESS).
Armenia adds around 615 MW of solar in 2025
Armenia enjoyed a record year for solar deployment last year, surpassing 1 GW of cumulative solar capacity. The market is currently led by autonomous solar producers, of which there are now more than 50,000 in the country.
100 MW Hertz 1 battery enters operation after Estonia–Finland grid incident
The 100 MW/200 MWh battery energy storage project in Kiisa began operation on Feb. 3 as scheduled – just two weeks after a testing fault at the facility caused the most significant disturbance to the regional power grid since Estonia’s desynchronization from the Russian electricity system.
Key takeaways from Solar Flex Prague
Czechia’s first international conference on solar and flexibility highlighted that the combination of solar with storage and flexibility sources is key to not just Czechia’s, but also Europe’s, secure and competitive electricity system.
Bulgaria installs 1.4 GW of solar in 2025
Bulgaria installed over 1 GW of solar for the third consecutive year in 2025 and is forecast to add over 2 GW this year thanks to a large pipeline of utility-scale projects.
Testing fault at 100 MW battery disrupts Estonia-Finland power link
During testing at Estonia’s 100 MW Kiisa battery park, both EstLink 1 and EstLink 2 tripped, triggering the most severe disturbance to the regional power grid since desynchronization from the Russian electricity system. As a result, nearly 1 GW of capacity was lost within seconds. The park’s owner has since publicly pointed to the battery manufacturer.
Serbia installs 134.3 MW of solar in 2025
Serbia had a record year for solar additions in 2025, led by deployment of large-scale plants. The country has a gigawatt-size project pipeline, although most remain in the earlier stages of development and are not expected to come online this year.
