Taiwan-headquartered HD Renewable Energy is preparing for major international expansion in 2026 with a strong focus on battery energy storage. The company announced its December 2025 revenue at NT$1.636 billion and full-year revenue at NT$8.78 billion, which represents a 13.29% decline from the previous year. Despite the decrease, the company said it is ready to increase development activities in 2026 and expects around 897 MW of overseas projects to begin construction within the year. HDRE’s general manager, Jason Shih-Chang Chou, said energy storage will become a key infrastructure for power stability, renewable energy integration, and data center operations, especially as global electricity systems face new demands in the AI era.
Recent progress in Australia and Japan is central to the company’s strategy. In South Australia, the 111 MW/330 MWh Templers Battery Project, developed in partnership with ZEN Energy, began commercial operations in December. This follows a 20-year offtake agreement for the project. The joint venture has already secured a 695MW pipeline of energy storage assets in the country and is also acquiring projects in Japan. HDRE previously said its combined solar and storage capacity in Australia could reach 2.7 GW by 2028.
In Japan, HDRE and its partner Manoa Energy brought a 50 MW/104 MWh battery storage facility into commercial operation in Hokkaido. The project will earn revenue from wholesale trading and grid services, and the company estimates that first-year trading income could reach JP¥2 billion. HDRE has also been successful in Japan’s Long-Term Decarbonization Power Source Auction, winning 300 MW in 2025. Although the scheme offers lower returns, it provides stable, government-backed long-term payments that improve bankability for storage developers. The company also benefited from Tokyo Metropolitan Government subsidies for a 20 MW project in Gunma Prefecture.
In Taiwan, HDRE has around 3.3 GW of capacity in development over the next three years and recently received strategic investment from Mitsubishi Electric. The company formed a partnership with Gigastorage Corporation to develop storage assets through a new platform called Xingguo Power. The platform will target opportunities in Taiwan’s capacity market, scheduled to launch in 2026. Its first project is a 100 MW battery system in Taichung, which will participate in regulation reserve and electricity trading markets. HDRE is also strengthening its position in the energy trading sector after merging with StarPower Energy in 2025.
