Taipower announced today (4/20) that the Longtan Ultra-High Voltage Substation (E/S) energy storage equipment system tender was won by the TECO team with a bid of NT$2.6 billion.

In order to meet the 2025 renewable energy target, Taipower plans to build a 160MW energy storage facility at its own site. The energy storage system of the Longtan UHV Substation is the largest facility in Taiwan with an installation capacity that is first among 29 UHV substation sites in Taiwan at a scale of 60MW, accounting for 37.5% of Taipower's self-built energy storage capacity, and is also an important node of Taiwan's 345KV ultra-high voltage transmission lines.

TECO stated that the project is expected to start construction in April 2022 and be completed and put into use in 2023. The projects covers the provision of auxiliary services and stabilization of Taiwan's power system, which will facilitate the integration and testing of the interface between the ultra-high voltage substation and the energy storage system, making the power system more secure and reliable. TECO Chairman, Sophia Chwen-Jy Chiu, pointed out that in the future, after a large number of offshore wind power are added to the Taipower system, an energy storage system will play an important role in the stability of the power grid.

TECO Chairman, Sophia Chwen-Jy Chiu, stated that the energy storage equipment system of the Longtan E/S substation is construction that is nationally important, and TECO won the bid to contract the turnkey project mainly because TECO not only has the ability and experience to construct large-scale energy storage systems, the team has also joined the international energy storage leader Fluence. In the future, it is expected to assist Taiwan in stabilizing power supply and sustainable services, making Taiwan's power system more secure and reliable.
