Sunotec Forms New Partnership Backed By Blackstone Investment To Accelerate Solar And Battery Storage Growth Across Europe

Sunotec, a major European integrator of utility-scale solar and battery storage projects, has announced a new partnership supported by a structured equity investment from funds managed by Blackstone Tactical Opportunities. This investment marks a significant step in Sunotec’s plan to strengthen its position across Europe and expand into complementary areas of energy infrastructure.

Blackstone’s backing will help drive Sunotec’s continued growth in its core markets, including Germany, the United Kingdom, Scandinavia and Southeast Europe. It will also support the company’s efforts to broaden its existing services and develop new capabilities, such as grid-related infrastructure.

Beyond expanding its operational footprint, the partnership aims to accelerate the growth of Sunotec’s hybrid renewable energy asset platform and deepen its commitment to sustainable infrastructure investment across the region. Sunotec has become one of Europe’s most established companies in the construction and integration of large-scale solar and battery energy storage systems.

The company has already installed around 15 GW of solar capacity across different markets. In just the past two years, Sunotec delivered 5 GW of utility-scale solar and 5 GWh of battery storage projects, demonstrating its ability to capitalize on the accelerating demand for renewable energy and the broader electrification trend underway across the continent.

In addition to its installation activities, Sunotec has built a diverse and rapidly growing portfolio of energy infrastructure assets that spans renewable technologies and deployment strategies. The company plans to build on this momentum, with ambitions to expand further and play an even more proactive role in supporting Europe’s ongoing energy transition.

The partnership brings together Blackstone’s strategic focus on digital and renewable energy infrastructure and its experience in electricity grid-related investments with Sunotec’s strong engineering, deployment and operational capabilities.

It also leverages Sunotec’s specialised expertise in integrating medium- and high-voltage grid infrastructure, a crucial component of Europe’s evolving energy system. Sunotec’s founders and leadership team will continue to hold a majority share in the company and will retain full responsibility for its strategy and day-to-day operations.

Kaloyan Velichkov, Founder and CEO of Sunotec, noted that Blackstone’s investment represents a major milestone for the company. He emphasized that Sunotec has grown into one of Europe’s leading large-scale solar and storage businesses over the past 13 years by focusing on execution, speed and consistent delivery.

Velichkov added that partnering with Blackstone will allow Sunotec to accelerate its expansion across Europe and thoughtfully enter new markets. At a time when renewable energy, battery storage and supporting grid infrastructure need to be deployed faster than ever, he said this partnership will give Sunotec the resources and capacity needed to deliver at scale.

Amer Khatoun, Senior Managing Director at Blackstone Tactical Opportunities, stated that Sunotec has established a strong reputation for delivering and operating large-scale solar and battery storage projects. He expressed enthusiasm for the partnership and reaffirmed Blackstone’s commitment to supporting Sunotec as it expands its integrated platform, grows its asset base and strengthens its expertise in grid infrastructure.

J.P. Morgan SE served as Exclusive Financial Adviser and Sole Placement Agent to Sunotec, while Linklaters and DGKV provided legal counsel. For Blackstone, Nomura Greentech acted as M&A Adviser, and Kirkland & Ellis LLP served as Legal Adviser. The transaction remains subject to regulatory approvals and is expected to be completed in the first half of 2026.
