The Solar Energy Association of Ukraine held an open meeting of its Battery Energy Storage Systems (BESS) Committee together with the Polish SEAU member company BT Storage on the topic “Energy Storage in Practice: EPC Support from Experts and BESS Technology Manufacturers.”
The event took place online on October 9, 2025, bringing together Ukrainian renewable energy professionals, EPC companies, and international experts from Poland.
The meeting was moderated by Serhii Ruchko, Head of SEAU’s ESS Committee, who emphasized the importance of international cooperation:
“SEAU is not only a platform uniting market participants but also a space for international knowledge exchange. We are grateful to our Polish partners for sharing their practical experience in implementing energy storage systems.”
Piotr Masłocha, Technical Project Coordinator at BT Storage (Poland), presented the proven EPC Ready model, which has demonstrated high efficiency in large-scale energy storage projects.
BT Storage is a team of engineers that designs, integrates, and maintains energy storage systems, providing full-cycle support for EPC companies—from technical design to commissioning.
In his presentation, Piotr Masłocha highlighted key challenges faced by EPC companies and ways to address them:
- Underestimating the role of EMS (Energy Management System) – the EMS defines the profitability of BESS projects.
- Lack of experience in technology selection – choosing the wrong equipment can lead to incompatibility or reduced efficiency.
- Lack of ROI analytics – investors require clear financial models showing profitability and payback timelines.
BT Storage provides EPC companies with full support, including technical documentation, ROI modeling, investor consulting, EMS and SCADA integration, as well as local service and personnel training.
Patrycja Schenk, Sales Manager at CHINT Power Systems Poland, presented the company’s experience in implementing energy storage systems across Europe and Ukraine.
CHINT is a global manufacturer of renewable energy and energy storage solutions, operating in more than 40 countries worldwide.
During the presentation, an example of a project in Mykolaiv, Ukraine, was showcased:
- 60 MW of energy storage + 18 MW of solar generation;
- Use of BESS for grid stabilization, peak shaving, and power balancing;
- Cooperation with BT Storage as EPC integrator, ensuring rapid commissioning and minimized technical risks.
The company operates a service center and spare parts warehouse in Kazimierz Wielki (Poland), allowing for prompt responses to partner requests from Ukraine and efficient technical maintenance.
CHINT presented three categories of BESS systems for different scales:
- C&I Turnkey Solution 400V – for small and medium-sized businesses;
- All-in-One Liquid Cooling System 800V – for medium and large facilities;
- Utility-Scale System – scalable solutions for large EPC projects.
The collaboration model between BT Storage (EPC integrator) and CHINT Power Systems (technology manufacturer) has proven highly effective in Poland and is now being actively adapted for the Ukrainian market.
Its advantages include:
- Reduced project implementation time;
- Minimized technical risks;
- Full local support in Poland and Ukraine;
- Proven technologies tested in European projects.
During the event, experts provided detailed answers to participants’ questions.
The Solar Energy Association of Ukraine thanks its member company BT Storage and representatives of CHINT Power Systems Poland for their cooperation and practical knowledge exchange. Such meetings help Ukrainian EPC companies better understand the processes of implementing energy storage systems, build reliable partnerships, and drive the development of Ukraine’s renewable energy market.
Detailed webinar materials and presentation recordings will soon be available to SEAU members in the upcoming issue of the “Solar Digest”. SEAU members may also request access to recordings of events held on the Association’s platform.
