• Taipower has built a 20 MW energy storage system at Tainan's Salt Field Solar PV Farm, consisting of eight 20-foot storage containers with more than 1,000 lithium battery modules. The total electricity storage capacity reaches 20,000 kWh, which is equivalent to the power consumption of 40,000 households for one hour. After its official launch today, it will not only be the first solar power storage system, but also the largest energy storage system in Taiwan.

Taiwan's first solar power plant with energy storage is born! Taipower previously installed energy storage systems at the Kinmen Hsiahsing Power Plant and the Lanyu Power Plant to create an outlying island smart grid, and now it is introducing green energy for the first time. Taipower’s Tainan Salt Field Solar PV Farm, which opened in 2020, is a collaboration with well-known new energy enterprise United Renewable Energy. Established as the first “solar power storage system”, the storage system, which officially opened today (January 6), integrates green energy and boasts a capacity of 20 MW (megawatts), making it the largest storage system in Taiwan. According to Taipower, the energy storage system features fast charging and discharging, which assists in the stable regulation of solar power generation into the grid, and can be used in combination with existing units to enhance the stability and flexibility of the power system, providing stable power immediately in case of unexpected power events.

This morning, Taipower held the opening ceremony for the Tainan Salt Field Solar Power Storage System. Tainan City Vice Mayor Yeh Tse-Shan, Taipower President Wang Yao-Ting, Energy and Storage Committee Chairman Hu Hui-Sen, and United Renewable Energy CEO Pan Wen-Hui all witnessed the official opening of the largest energy storage system in Taiwan.

According to Taipower, in 2020, it installed 480,000 photovoltaic panels on 214 hectares of abandoned salt flats in Tainan’s Jiangjun and Cigu districts to build the Tainan Salt Field Solar PV Farm; it had a capacity of 150MW (megawatts), which was the largest in Taiwan at the time. The Tainan Salt Field Solar PV Farm can generate an average of 200 million kWh of electricity per year, which is equivalent to the annual electricity consumption of nearly 50,000 households, and brings over 100,000 metric tons of carbon reduction benefits per year, while maintaining the site's existing detention basin function. With the continuous development of green energy in recent years, in order to maximize the benefits of green energy, Taipower has built its first “solar power storage system” in conjunction with the Tainan Salt Field Solar PV Farm.

Taipower pointed out that it cooperated with a well-known new energy company, United Renewable Energy, to build a 20 MW/20 MWh (megawatt-hour) energy storage system at the Tainan Salt Field Solar PV Farm, with eight 20-foot storage containers built by Saft, a century-old French battery manufacturer that provided battery services for Boeing airliners in the United States, using more than 1,000 lithium battery modules, and adopting transformers from Shihlin Electric, a major domestic heavy electric product manufacturer as well as equipping power regulation systems. The total electricity storage capacity reaches 20,000 kWh, which is equivalent to the power consumption of 40,000 households for one hour. After its official launch today, it will not only be the first solar power storage system, but also the largest energy storage system in Taiwan.

• Taipower’s Tainan Salt Field Solar PV Farm combined power and Tainan’s local elements to design a series of identifiers, which are painted on the energy storage containers.

• The energy storage system’s fast charging and discharging characteristics can help integrate solar power into the grid, reduce system fluctuations, maintain grid stability, and even store the daytime peak generated solar power for use during nighttime peak hours or in case of power emergencies. A response speed up to 1,000 times faster than conventional generating units enables it to provide immediate stable power and creates a buffer time for repair and restoration.

Taipower indicated that the combination of green energy and energy storage balances environmental sustainability with the need for a stable power supply; it has become an international trend in energy use and echoes the government’s 2025 target for energy storage systems. In addition to building the first solar power storage system and the largest energy storage system at Tainan Salt Field Solar PV Farm, Taipower will continue to build its own systems and energy ancillary service trading models to achieve the target of 1000 MW.
