System integrator Fluence has provided a 60MW/80MWh battery energy storage system (BESS) in Taiwan, which has begun commercial operation.
State-owned utility Taiwan Power Company (TPC) deployed the project, located at the Taoyuan Longtan Ultra High Voltage Substation.
Fluence provided the BESS equipment, while Taiwan-based industrial and electrical group TECO Electric & Machinery Co., Ltd. (TECO) is the local partner for the project.
Fluence said this is the largest BESS project by TPC so far and is part of its initiative to implement 1,000MWh of energy storage on its grid by 2025.
In the next few years, Taiwan will deploy a large amount of offshore wind power, and energy storage will play a critical role in integrating intermittent generation into the grid.
Wind farms on the grid typically mean more opportunities for storage around ancillary services, while solar-dominated grids provide more load shift opportunities. So far, most large-scale BESS in Taiwan has been mainly for the ancillary services market, which explains their short durations.
A recent example is Taiwan's 311MWh BESS from EV and BESS company NHOA, which is designed specifically for a new ancillary service called E-dReg.
This project is Fluence's second in the country, first announced in April 2022. Fluence's first system was a 6MW/6MWh system for independent power producer (IPP) Ina Energy, also deployed in cooperation with TECO.
A few months later, Fluence partnered with power electronics and engineering company Rich Electric to develop its largest 100MW/100MWh system.
