Jun 2023Undisclosed stageEuropean Bank for Reconstruction and Development (lead)$33MSunly is an Estonia-based renewable energy developer and independent power producer operating in the Baltic states and Poland, focusing on solar and wind parks. In 2023, it raised approximately €200 million in equity from existing investors including Mirova and the European Bank for Reconstruction and Development (EBRD), with EBRD investing €30 million for a minority stake to support development and construction of projects. This round aligned with Sunly's expansion, including a 26 GW total portfolio and 10 GW risk-weighted portfolio as of its 2023 annual report. The 2023 capital raise was part of broader funding efforts, later followed by additional EBRD investment of up to €37 million in 2024 as part of a €260 million capital increase where Mirova took a substantial stake, bringing EBRD's total to €67 million. Sunly reported 230 MW operational and 126 MW under construction solar parks, plus 2 MWh storage, with projects like the 45 MW Raba solar park starting construction financed by €18 million from Swedbank. By end-2023, Sunly had integrated principles from new investors like Mirova and EBRD. Subsequent financings included €300 million debt in 2024 from Rivage, Copenhagen Infrastructure Partners, and others for projects like the 244 MW Risti solar park and Latvian solar developments, bringing total debt and equity to €765 million. In 2025, Sunly secured nearly €85 million in loans from EIB, EBRD, and SEB for 329 MW Latvian solar parks costing €203.9 million total. A €60 million equity round closed later from existing shareholders including EBRD, Mirova, and Vardar, pushing cumulative funding to €825 million to reach 1 GW operational capacity by 2026 and 4.6 GW by 2030.

Sunly also acquired Polish solar developer Alseva and plans to grow its team from 135 to 400 employees while offering stock options. Financially, Sunly reported revenues of EUR 29.2 million in 2022, up significantly from EUR 2.1 million in 2021, driven by operational growth and investments of EUR 34.7 million that year.

Prior to this round, Sunly had raised EUR 28 million in 2021 from Estonian and other investors including Vardar, bringing total prior equity to EUR 44 million.
