What They Do
Sunly specializes in the development, ownership, and operation of renewable energy projects focused on wind, solar, and battery storage technologies, primarily serving the Baltic region and Poland. The company integrates electricity retail services directly to households and businesses in Estonia under its own brand, creating a hybrid business model that spans project development, asset ownership, energy balancing, and customer-facing power sales (source: sunly.ee). Beyond renewables, Sunly is expanding into adjacent infrastructure sectors, including a data-centre-related project in Estonia, reflecting its strategic diversification (source: sunly.ee). The company also invests in electrification startups, positioning itself at the forefront of energy transition technologies and infrastructure innovation (source: eib.org).
Projects & Track Record
Sunly operates and develops a substantial portfolio of renewable energy parks across the Baltics and Poland, with approximately 1 GW of operational and under-construction capacity and a development pipeline totaling 6.4 GW (source: sunly.ee). Notable projects include the 244 MW Risti solar park in western Estonia, recognized as the largest photovoltaic site in the Baltics, which also features an approved 144 MW / 600 MWh battery storage system (source: eib.org). Additionally, Sunly has developed the 45 MW Raba solar park in Estonia and is advancing a 329 MW solar buildout in Latvia, supported by nearly €85 million in international financing, with sites located in Valmiera, Krāslava, Madona, and Saldus municipalities (source: eib.org). The company is also engaged in partnerships for battery storage and data center infrastructure, including collaboration with Metsagrupp on the Risti battery project and Magnora Data Center ASA on the Risti Kampus data-centre development (source: sunly.ee).
Recent Developments
In recent years, Sunly has significantly scaled its operations and financing, raising €825 million from international investors such as the European Bank for Reconstruction and Development (EBRD), Copenhagen Infrastructure Partners, Mirova, and Rivage (source: eib.org). The company has commenced construction of the Risti solar park and is actively developing hybrid renewable projects combining solar, wind, and battery storage. Sunly has also broadened its portfolio by partnering with Deep Wind Offshore and VALOREM Group under the Tuul Energy initiative to explore offshore wind opportunities in Estonia (source: sunly.ee). Furthermore, Sunly has launched electricity retail services to households in Estonia, marking a strategic expansion into customer-facing energy sales (source: sunly.ee).
Working There
Sunly offers diverse career opportunities across project development, engineering, finance, operations, commercial retail, and corporate functions, with its main office located in Tallinn and additional presence in Riga, Vilnius, and Warsaw (source: sunly.ee). The company’s hybrid business model creates demand for roles in trading, customer operations, product support, project finance, land acquisition, permitting, grid connection, and asset management (source: sunly.ee). Sunly’s culture reflects a dynamic, growth-oriented environment focused on launching and operating large-scale renewable assets and expanding across multiple countries, rather than a traditional utility approach (source: eib.org). Employee benefits are not extensively documented publicly, though the company offers access to green electricity plans for customers (source: sunly.ee).
