(8 April 2026 ─ Hong Kong) CTF Services Limited (“CTFS” or “the Group”; Hong Kong stock code: 659) is pleased to announce that it is partnering with Unisun Energy Services GmbH (“Unisun”), a global renewable energy solutions service provider to develop a Battery Energy Storage System (BESS) project in Europe, to capitalize on opportunities in the European energy storage market. CTFS will hold a 75% stake in the first BESS project, while Unisun will hold 25%.
Unisun is a leading global renewable energy solutions service provider, having entered the European renewable energy market as early as 2024, with businesses spanning the investment, development and operation of commercial and industrial photovoltaic projects and behind-the-meter energy storage systems. The company is committed to delivering one-stop green energy solutions to customers worldwide, supporting the achievement of net-zero carbon goals. As the technical lead of the project, Unisun will leverage its extensive expertise and solid track record in the energy storage sector to oversee project development, engineering design and construction management, ensuring that the project meets the highest standards of efficiency and sustainability. This collaboration brings together CTFS’s global expertise, strong capital base and strategic conviction in the project’s potential with Unisun’s deep technical capabilities and operational experience in energy storage sector.
The first BESS project under the partnership will be located in Finland, aiming to address the growing seasonal imbalance between energy production and consumption in Europe, while meeting the higher standards of national grid stability. The project has a total energy storage installed capacity of 30 MW/65.2 MWh and is expected to complete construction and commence operation in Q4 this year. Both parties believe that this cooperation will not only accelerate project implementation but also lay a solid foundation for further collaboration in the future. The project fully demonstrates CTFS’s strategic approach of integrating ESG principles into its core business, as well as its active participation in the global transition towards renewable energy.
Mr. Brian Cheng, Executive Director and Group Co-Chief Executive Officer of CTFS, said: "We are delighted to partner with Unisun, leveraging our complementary strengths in investment strategy and technical expertise. This collaboration is not merely an investment project, but also an important step in our Group’s journey to support next-generation infrastructure for the AI era. CTFS has long been committed to sustainable development and has exited its fossil fuel investments to focus on green energy opportunities. With the surge of renewable energy production and grid capacity upgrading in Europe, we believe the timing for BESS investment opportunities is now mature, and our first Finland project offers attractive return potential while aligning with our long-term commitment in ESG. Unisun is an ideal technical partner for our expansion in the renewable energy market, supporting us in effectively addressing technical challenges and capturing strategic opportunities arising from the region’s energy transition.”
