  A landmark moment for Europe’s energy transition is now a reality on site! 

  We are thrilled to announce a major milestone in the European BESS sector. The equipment for the continent's largest single-project Battery Energy Storage System is officially fully mounted and awaiting final commissioning.

  Here is what makes this achievement stand out:

  ⚡ Record Capacity: A massive 601,92 MWh at a single project site.

  Seamless Logistics: Just 4.5 months from contract signature to the port, and 5 months for complete on-site delivery. Navigating complex global supply chains was managed so smoothly that the final inland transport and installation were executed with calculated precision, completely ahead of stress.

  A project of this magnitude is a masterclass in collaboration. Proud of the partners who made it happen:

  Investor & Installation: SUNOTEC (via dedicated SPV) – driving the investment vision and expertly executing the physical construction and mounting on site.

  Contractor: DMT Energy Ltd. – a 100% Bulgarian entity leading the execution, part of DMT Prime.

  Manufacturer: CRRC Zhuzhou Institute Co., Ltd. – Bloomberg Tier 1, the #1 BESS integrator in China, and #2 globally.

  Inland Logistics: Unimasters Logistics – ensuring flawless unloading and inland delivery.

  Insurance Broker: Renewable Energy Insurance Broker – securing the journey every step of the way.

  It takes a dedicated team of professionals to set new standards for large-scale energy infrastructure. Watch the sheer scale of the installation in the video below!
