Fluence-supplied 60MW/80MWh Taiwan BESS starts operations


System integrator Fluence has supplied a 60MW/80MWh battery energy storage system (BESS) in Taiwan, which has started commercial operations.

State-owned utility Taiwan Power Company (Taipower) deployed the project, and is located at the Taoyuan Longtan ultra-high voltage substation.

Fluence provided the BESS units while Taiwan-headquartered industrial and electrical conglomerate TECO Electric & Machinery Co. (TECO) was the local partner for the project.

Fluence said it is Taipower’s largest BESS project to-date, part of the utility’s move to have 1,000MWh of energy storage on its network by 2025.

A large amount of offshore wind is expected to be deployed in Taiwan in the coming years, and energy storage will play a crucial role in integrating its intermittent generation into the electricity grid.

Wind-dominated energy grids typically mean opportunities for energy storage are more around ancillary services, while solar-dominated grids provide more opportunities for load shifting, and so far most large-scale BESS in Taiwan have primarily targeted the ancillary service market, which explains their short duration.

A recent example was a 311MWh BESS in Taiwan from EV and BESS firm NHOA, which was specifically designed for a new ancillary service called E-dReg.

The project is Fluence’s second in the country, and was first announced in April 2022. Fluence’s first was a 6MW/6MWh system for independent power producer (IPP) Ina Energy, also deployed through a partnership with TECO.

A few months later, Fluence partnered with power electronics and engineering firm Rich Electric for a 100MW/100MWh system, its largest.’ publisher Solar Media will host the 2nd Energy Storage Summit Asia, 9-10 July 2024 in Singapore. The event will help give clarity on this nascent, yet quickly growing market, bringing together a community of credible independent generators, policymakers, banks, funds, off-takers and technology providers. For more information, go to the website.
