Sunotec has secured a structured equity investment from funds managed by Blackstone Tactical Opportunities to support its renewable infrastructure expansion.
The company said the partnership will drive growth across core European markets including Germany, the United Kingdom, Scandinavia and Southeast Europe while expanding services and grid capabilities.
Blackstone added that the investment will help scale Sunotec’s hybrid renewable energy asset platform and strengthen its focus on sustainable infrastructure.
Sunotec has installed approximately 15GW of solar capacity across multiple markets, including 5GW of utility-scale solar and 5GWh of battery energy storage systems in the last two years.
The company’s founders and leadership will remain majority shareholders and retain control of its strategy and operations.
“Blackstone’s investment marks an important milestone in Sunotec’s journey. Over the past 13 years, our team has built one of Europe’s leading large-scale solar and storage businesses through execution, speed and a relentless focus on delivery,” said Kaloyan Velichkov (pictured), founder and chief executive of Sunotec.
“With Blackstone as a partner, we will accelerate our expansion across Europe and enter selective new markets.”
“Sunotec has built a strong track record delivering and operating utility-scale solar and battery storage projects. We are delighted to partner with the company as it continues to scale its integrated platform, expand its operating asset base and deepen its grid infrastructure capabilities,” said Amer Khatoun, senior managing director at Blackstone Tactical Opportunities.
The transaction is subject to regulatory approvals and is expected to close in the first half of 2026.
