SUNOTEC, one of Europe’s leading integrated solution providers for large-scale solar projects, has successfully secured financing for seven renewable energy projects in Bulgaria during September 2025.
These projects are owned either fully by SUNOTEC or partially through Solaris Holding AD (a 50/50 joint venture between SUNOTEC and the main shareholders of Eurohold Bulgaria AD, a diversified energy and finance group with a strong presence across the Balkans). The financed portfolio includes one co-located project (Solar PV and BESS) and six standalone Battery Energy Storage System projects, marking a significant step in expanding the company’s investment portfolio in its home market.
In total, they comprise 115 MWp of solar capacity and 763 MWh of battery storage.
'These projects mark a major milestone in our evolution not only as a turnkey solutions provider, but also as a long-term investor in renewable energy infrastructure,' said Viktor Stefanov, Head of IPP at SUNOTEC. 'With these investments, we are contributing to Bulgaria’s energy independence and to building a more resilient, flexible and renewable power system.'
The Bulgarian Ministry of Energy has also approved the standalone BESS projects to receive subsidies under the Restore program, which is designed to support large-scale storage deployment and enhance grid stability nationwide.
The projects represent an important milestone in the decarbonisation of the Bulgarian power sector, supporting the country’s transition toward a cleaner energy mix. As power markets across Europe increasingly recognise the value of BESS as key enablers of the energy transition, SUNOTEC continues to play a leading role in driving innovation and investment in this field.
This achievement further strengthens SUNOTEC’s and Solaris Holding's position as one of Bulgaria’s leading investors in Solar PV and energy storage, complementing its existing operational assets in Bulgaria, namely Pernik, Verinsko, and Selanovtsi.
