Taiwan’s Largest Solar-Plus-Storage Project Launches in Changhua with 185.7 MWh Capacity
Tai Pu Wei Energy announced on August 10 that it has secured the 48 MW solar PV and 185.7 MWh energy storage system project in Changhua for HEXA Renewables. The project is expected to be grid-connected in Q1 2027 and commence commercial operation in Q2 2027. Once completed, it will become Taiwan’s largest PV+BESS solar-plus-storage integration project, utilizing energy storage to bridge the gap between solar power generation and peak demand periods, thereby improving overall renewable energy efficiency.
Tai Pu Wei Energy is responsible for the project’s full EPC (Engineering, Procurement, and Construction) scope, including system integration, construction, testing, and grid connection. Feng Hao-xiang, General Manager of Tai Pu Wei, stated that large-scale solar-plus-storage projects require the integration of multiple capabilities, such as power system design, equipment integration, construction, energy management system (EMS) control, and long-term operation and maintenance. These challenges test a company’s comprehensive strength. To ensure system stability, Tai Pu Wei will collaborate with global energy storage leader Fluence Energy, introducing advanced storage technology and providing up to 17 years of operation and maintenance services.
Feng noted that this partnership combines Fluence’s global supply chain and long-term service experience with Tai Pu Wei’s local operation and maintenance expertise, significantly enhancing system stability and long-term operational performance. Upon completion, the project will store excess solar power generated during the day and release it during peak demand periods, further improving renewable energy utilization and grid flexibility.
Tai Pu Wei Expands Energy Storage Footprint Across Taiwan, Australia, and Japan with Over 1,000 MWh Capacity
Tai Pu Wei Energy has been actively expanding its energy storage business in recent years. As of August 2026, the company has accumulated a total of 412 MW in solar PV and energy storage installations globally, with a combined storage capacity of 1,055 MWh across markets including Taiwan, Australia, and Japan. In Taiwan, in addition to the 48 MW/185.7 MWh solar-plus-storage project in Changhua, the company continues to develop other energy storage projects to address the growing demand for power dispatch as renewable energy capacity increases.
In overseas markets, Tai Pu Wei’s projects in Australia have already begun contributing to revenue, while its operations in Japan continue to recognize income from high-voltage energy storage projects. The company is also actively developing ultra-high-voltage and low-voltage projects. Tai Pu Wei stated that as overseas projects advance, the Australian and Japanese markets are expected to become key drivers of future growth. Through its cross-regional expansion, the company not only strengthens its technical capabilities but also provides more diverse solutions for the global energy transition.
Taiwan’s installed renewable energy capacity continues to grow, but a significant mismatch exists between solar power generation periods and peak electricity demand, leading to increasing curtailment of solar power. Solar-plus-storage integration technology can effectively store excess daytime power and release it during nighttime or peak demand periods, improving renewable energy efficiency while reducing grid strain. This provides a more stable foundation for Taiwan’s energy transition. The launch of the 185.7 MWh solar-plus-storage project in Changhua marks a new milestone for Taiwan’s energy storage industry, with more large-scale solar-plus-storage projects expected to follow to meet the demands of the energy transition.
