Testing on Japan’s Hokkaido Electric Power (HEPCO) and Sumitomo Electric Industries (SEI) 15-MW redox flow storage battery system has begun.
Verification of SEI’s 60MWh battery, installed on the northern island of Hokkaido, will last for around three years.
The scheme aims to test the efficiency of the system in adjusting wind and solar intermittency and to develop optimal control technologies.
The system, which is one of the world’s largest redox flow batteries, is located at the Minamihayakita Transformer Station in Abira-chou.
The project is funded by Japan’s Ministry of Economy, Trade and Industry (METI) under its “Emergency Verification Project for Large-scale Storage Battery System in 2012” programme.
HEPCO and SEI announced the completion of the storage battery system on December 25, 2015.
