Wärtsilä will supply a 5.2 MW / 5.2 MWh energy storage system to provide the frequency regulation in the ancillary service market for the Taiwanese grid as the country seeks to achieve 20 percent of its energy from renewable sources by 2025.
The order was placed in August 2021 by Shangfa Construction who will build the energy storage facility on behalf of North-Star International. Taiwan’s state-owned integrated utility, Taiwan Power Company, has opened a day-ahead ancillary service market, including frequency regulation, spinning reserve and supplement reserve services. The Wärtsilä system will allow North-Star International to provide the frequency regulation and spinning reserve services. Frequency regulation will enable the integration of greater levels of renewables, while the Wärtsilä energy storage solution will support frequency stability and enhance the reliability of the system. The Beimen Energy Storage project will be in the city of Kaohsiung in Taiwan. It will include Wärtsilä’s Gridsolv Quantum. The system will be operational in late Q1, 2022.
