Blackstone Tactical Opportunities backs Sunotec

Solar and battery storage developer Sunotec forged a partnership with Blackstone’s investment platform Blackstone Tactical Opportunities.

Sofia-based Sunotec announced a partnership structured equity investment from funds managed by Blackstone Tactical Opportunities.

Blackstone is one of the world’s largest alternative asset managers. It has USD 1.3 trillion in assets under management.

Blackstone’s investment will support Sunotec’s continued growth across its core European markets — notably Germany, the United Kingdom, Scandinavia and Southeast Europe — while enabling further expansion of its existing services and the development of adjacent capabilities, including grid infrastructure, according to Sunotec.

The partnership will also aim to scale up Sunotec’s hybrid renewable energy asset platform and reinforce its investments in sustainable infrastructure.

Sunotec has installed approximately 15 GW of solar capacity across multiple markets, including 5 GW of utility-scale solar and 5 GWh of battery energy storage systems (BESS). The investments were implemented in the last two years alone, the company noted.

Sunotec’s founders and leadership will remain majority shareholders and continue to control the company, its strategy and operations, the update reads.

Amer Khatoun, Senior Managing Director of Blackstone Tactical Opportunities, pointed out that Sunotec has built a strong track record delivering and operating utility-scale solar and battery storage projects.

According to Kaloyan Velichkov, Sunotec Founder and CEO, 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,” Velichkov stressed.

The transaction is subject to regulatory approvals and is expected to close in H1 2026.
