Sumitomo installs 125 kW redox flow battery in Taiwan

By Brian Publicover

The Japanese electrical equipment supplier provided the battery to Taiwan Power Research Institute, which will pair the system with variable renewables such as solar in a pilot project.

Taiwan continues its push towards renewable technologies. The Taiwan Power Research Institute (TPRI) is now looking into redox flow electrical storage in a new project.

TPRI is an entity under Taiwan Power Co., the state-owned utility most commonly known as Taipower. Through a series of demonstration projects, TPRI is experimenting with ways to control peak demand and smooth out the variability of renewables such as solar.

The Sumitomo Electric Industries battery will be tested with electricity generated by solar panels, wind turbines, and diesel generators. TPRI ordered the redox flow battery from Sumitomo Electric in May 2016. The installation of the system was completed in February 2017.

In an online statement, the Japanese company said it would continue to back TPRI’s energy storage demonstration projects, but did not provide additional details.

Osaka-based Sumitomo Electric has supplied utility-scale storage solutions for a number of renewables-related demonstration projects in recent years. In 2013, it agreed to provide a 60 MWh vanadium redox flow battery for a substation operated by Japanese utility Hokkaido Electric Power, to regulate the transmission of PV and wind capacity.

And in early 2014, Sumitomo Electric’s parent paired a 10 MW solar project in Osaka with the first energy storage system in the world to run on used lithium-ion batteries pulled from electric vehicles.
