Acceleration of Renewable Energy Expansion in Europe: Blackstone Invests in Battery and Solar Specialist Sunotec
Sofia (Bulgaria) - The US investment firm Blackstone is providing Sunotec, a leading European provider of solar and battery storage solutions, with a strategic equity investment as part of a partnership. The aim is to enable Sunotec to expand its projects across Europe, enter new markets, and improve the integration of solar and storage systems into power grids.
Investment strengthens growth and expansion
Sunotec has received a significant, undisclosed equity investment from Blackstone Tactical Opportunities. The goal is to support Sunotec’s growth in core markets such as Germany, the United Kingdom, Scandinavia, and Southeastern Europe.
The funding is expected to drive the development of new services, particularly in the field of power grid infrastructure, and further expand the existing renewable energy platform.
“Blackstone’s investment marks an important milestone in Sunotec’s journey. With Blackstone as a partner, we will accelerate our expansion across Europe and enter selective new markets. At a time when the world’s energy transition needs faster deployment of renewable energy, battery storage and the grid infrastructure around it, this partnership gives us even greater capacity to deliver at scale,” said Kaloyan Velichkov, Founder and CEO of Sunotec, commenting on the deal.
Over the past two years, Sunotec has installed around 5 GW of solar capacity and 5 GWh of battery storage systems. In total, more than 15 GW of solar capacity has been delivered across several European markets.
J.P. Morgan SE acted as exclusive financial advisor and sole placement agent to Sunotec, while Linklaters and DGKV served as legal advisors.
Focus on renewable energy and grid infrastructure
The partnership combines Blackstone’s experience in digital and renewable energy infrastructure with Sunotec’s expertise in the planning, installation, operation, and maintenance of solar and battery storage systems, as well as the integration of medium- and high-voltage grids.
“Sunotec has built a strong track record of 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.
Nomura Greentech acted as M&A advisor to Blackstone, with Kirkland & Ellis LLP serving as the company’s legal advisor.
Sunotec’s founders and management will remain majority shareholders and retain control over strategy and operations. The transaction is subject to regulatory approvals and is expected to close in the first half of 2026.
Sunotec is headquartered in Sofia, Bulgaria, and has offices in Germany and the United Kingdom. Since its founding in 2012, more than 680 photovoltaic installations have been completed. The company employs more than 2,000 people worldwide. Blackstone, the world’s largest alternative asset manager, manages USD 1.3 trillion in assets, including infrastructure and renewable energy projects.
