Recently, leading energy storage companies have accelerated their business expansion across both domestic and overseas markets. BYD Energy Storage has completed the delivery of a 500 MWh energy storage project order in Bulgaria, while Risen Energy has intensified its efforts in China’s commercial and industrial (C&I) segment by signing strategic cooperation agreements with 16 companies, accelerating its penetration across multiple regions and application scenarios.
BYD Energy Storage announced that the 500 MWh standalone battery energy storage system (BESS) project at the Maritsa East 3 Power Plant in Bulgaria, for which it supplied the core battery energy storage systems, has officially entered commercial operation.
Developed and invested in by international power company ContourGlobal, the project is one of the largest standalone battery energy storage systems in Eastern Europe.
The project represents a key outcome of the strategic cooperation agreement signed by the two parties in December 2024. As the core equipment supplier, BYD Energy Storage delivered a complete set of key systems to ContourGlobal, including 110 energy storage units.
During the project construction phase, BYD Energy Storage leveraged its mature supply chain and technological strengths to ensure the on-schedule delivery and commissioning of equipment within a tight timeframe, enabling the project to be completed and connected to the grid just a few months after reaching final investment decision.
Recently, Risen Energy completed a new round of strategic partnership signings across several key regions, including South China, North China, and East China. In total, the company established in-depth cooperation with 16 customers, covering a wide range of application scenarios such as industrial parks, engineering and construction projects, and regional energy initiatives.
In the highly competitive East China market, which features relatively high market entry barriers, Risen Energy reached deep strategic cooperation with nine benchmark enterprises:
Strong alliances: Guocheng Energy and Jiangsu Tenenfa will leverage their EPC and investment strengths to jointly develop integrated solar-plus-storage projects.
Innovation-driven collaboration: Shanghai Mecksheng and Fujian Minxinan will introduce cutting-edge application scenarios into the partnerships, including “AI-powered power operations” and “green smart city” solutions, respectively.
Deep local engagement: Enterprises such as Zhejiang Huichuang, Quanzhou Nanwei, Wenzhou Chenxu, Ningbo Hengmao, and Nanjing Xisheng will integrate power equipment and solar-plus-storage operation and maintenance resources to jointly tap regional market potential.
At the same time, the company is achieving multi-point breakthroughs across both southern and northern markets:
South China: Partnering with five companies—Huizhou Zhixin, Hunan Xiangjian, Guangxi Yangsheng, Zhuhai Watt, and Zhaoqing Xiangde—Risen Energy will focus on zero-carbon industrial park transformation and power engineering services to accelerate project implementation.
North China: Working with Shandong Yueyang and Shandong Haina Ceramics, the company will use comprehensive “solar, wind, storage, and charging” services and manufacturing energy efficiency optimization as entry points to create new benchmarks for regional energy transition.
