Sunly has officially opened the Raba hybrid energy park in Põhja-Pärnumaa municipality, marking another milestone in Estonia’s renewable energy transition. The project combines Sunly’s existing 45 MW solar park, completed in 2024, with a new 21 MW / 48 MWh battery energy storage system (BESS). The integrated facility can store electricity generated during the day and discharge it in the evening, helping balance electricity supply and demand while providing greater flexibility to the grid.
TEGOS advised Sunly on the drafting of the operation and maintenance agreements for the battery energy storage system. This pioneering project in Estonia’s rapidly developing energy storage sector required tailored contractual arrangements and cross-disciplinary expertise spanning energy, IT and cybersecurity, data protection, and intellectual property law. TEGOS team included Sander Kärson, Imbi Jürgen, Priit Lätt, Liisa Levandi and Enelin Terav.
We congratulate Sunly on this landmark achievement and look forward to supporting their continued growth in renewable energy.
