German-Bulgarian solar photovoltaic developer Sunotec said on April 7 it has secured a structured equity investment from funds managed by Blackstone’s Tactical Opportunities unit to support its expansion across Europe.

The investment will help Sunotec expand in its core markets including Germany, the United Kingdom, Scandinavia and Southeast Europe, developing capabilities in areas such as electricity grid infrastructure and hybrid renewable energy systems.

Sunotec, headquartered in Sofia and Munich, develops and integrates utility-scale solar power and battery energy storage projects. The company said the partnership would help scale its renewable asset platform as Europe accelerates its shift towards low-carbon energy.

Founded in 2012, Sunotec has installed about 15 gigawatts (GW) of solar capacity across multiple markets. In the past two years alone, it has delivered around 5 GW of utility-scale solar projects and 5 gigawatt-hours (GWh) of battery energy storage systems.

The investment brings together Blackstone’s focus on infrastructure sectors such as renewable energy, digital infrastructure and electricity grid services with Sunotec’s engineering and project delivery capabilities in large-scale solar and battery storage systems.

Sunotec’s founders and management will remain majority shareholders and continue to control the company’s strategy and operations.

“Blackstone’s investment marks an important milestone in Sunotec’s journey,” Sunotec founder and chief executive Kaloyan Velichkov said in a statement, adding the partnership would accelerate the company’s expansion across Europe and into selected new markets.

Amer Khatoun, senior managing director at Blackstone Tactical Opportunities, said Sunotec had built a strong track record delivering and operating utility-scale solar and battery storage projects.

The transaction, which is subject to regulatory approvals, is expected to close in the first half of 2026.

J.P. Morgan SE acted as exclusive financial adviser and sole placement agent to Sunotec, while Nomura Greentech advised Blackstone on the deal.
