6 MW battery storage system planned for Taiwan

A 6MW / 6MWh battery-based energy storage system is being developed in Taoyuan, Taiwan. Fluence, a Siemens and AES company in the energy storage business, will cooperate with the Taiwan-based TECO Group and its subsidiary YATEC to offer automatic frequency control (AFC) services to the state-owned utility company Taipower.

According to the latest forecast from BloombergNEF (BNEF), energy storage installations around the world will reach a cumulative 358 GW/1028 GWh by the end of 2030, more than 20 times larger than the 17 GW/34 GWh online at the end of 2020. As part of its pledge to achieve 20% of the country’s electricity from renewable sources by 2025, up from approximately 5% in 2020, Taiwan has developed an energy policy that calls for increased renewable energy and LNG, significantly less coal, and a “nuclear-free homeland.”

According to Fluence, energy storage is needed to effectively integrate solar and wind power into the grid to seamlessly match power supply and demand. Taipower has made frequency control a top priority since the island’s traditionally centralized grid system has faced growing challenges from intermittent renewable energy sources trying to connect to the grid. Taipower has recognized the importance of battery storage in providing ancillary services to stabilize the grid and has targeted to boost its storage capacity to 590 MWh by 2025.

“Taiwan represents Fluence’s 30th market and demonstrates its commitment to utilizing its latest system technology to help make Taiwan’s power network stronger and more resilient, prepare it to accommodate more renewable energy adoption, and set the example for further clean energy deployments in the Asia Pacific region,” said Achal Sondhi, vice president of market growth for Asia Pacific at Fluence. “Fluence views Taiwan as a key market in the region, and we look forward to working with our customers and business partners there to enhance the energy storage efficiency of the island’s overall power ecosystem and open a new chapter for sustainable energy in Taiwan.”

YATEC, a subsidiary of TECO Group, is Fluence’s business partner in delivering its first battery-based energy storage system in Taiwan.
