SUNOTEC is looking forward to this exciting partnership with Sungrow. Collectively, they will be deploying 2.4 gigawatt hours (GWh) of BTS’ battery energy storage systems (BESS) to support solar power projects throughout Europe. This partnership is a key step toward building greater renewable energy management and storage infrastructure across the region. SUNOTEC only concentrates on large-scale projects. Our collective aim should be to address the growing energy storage demands created by the world’s energy transition.
For SUNOTEC, the collaboration happens inside their ambitious, entrepreneurial portfolio. This portfolio showcases a handful of diverse, nationwide projects that are serving to bolster grid stability and make it easier to integrate renewables. To contract the deployment of 2.4GWh of Battery Energy Storage Systems (BESS) will increase the reliability of SUNOTEC’s solar parks across Bulgaria and its frontier areas. These systems are among the largest, most advanced energy storage systems in the country and Europe.
Strategic Collaboration for Clean Energy
The signing ceremony between SUNOTEC and Sungrow solidified their joint commitment to accelerating clean energy initiatives in Bulgaria and Europe. Anastasios Gkinis, Southeast representative of Sungrow, highlighted just how critical this partnership is.
“This collaboration with SUNOTEC is a cornerstone of our mission to accelerate clean energy deployment in Bulgaria and across Europe.” – Anastasios Gkinis
This partnership falls directly in line with SUNOTEC’s long-term strategy to incorporate flexible and intelligent energy systems into its global solar infrastructure portfolio. The two companies are further teaming up to produce some high-profile, flagship installations. These projects will be examples to follow for the next generation of renewable energy projects.
Innovative Projects Supported by National Initiatives
In addition to the collaboration with Sungrow, several of SUNOTEC’s forthcoming projects will receive support from Bulgaria’s RESTORE national support programme. This funding will spur the creation of big, innovative projects aimed at producing fixed energy storage technology. It will be a huge step towards achieving the nation’s renewables goals.
Kaloyan Velichkov, founder and CEO of SUNOTEC, highlighted the significance of managing and storing renewable energy effectively for successful transitions.
“The global energy transition depends not only on how much renewable power we produce, but on how intelligently we manage and store.” – Kaloyan Velichkov
This view of the future highlights the need for innovative new energy storage technologies that will help us meet changing energy needs.
Recent Acquisitions Enhance Project Capacity
In July 2025, SUNOTEC took a step further to strengthen its business position by acquiring SIA DSE Lazas Solar’s solar and energy storage project in Latvia. After a great deal of hard work, they had done it! This purchase will lead to the development of a new photovoltaic (PV) solar power plant. It will have a projected capacity of 400 megawatts peak (MWp) and deliver 600 megawatt hours (MWh) of battery energy storage system (BESS).
These recent advances will position SUNOTEC to further consolidate SUNOTEC’s leadership in the growing renewable energy sector. In the process, they’ll further the broader European goal of making energy production and distribution more sustainable, diverse and reliable.
