Battery installed at Goldwind subsidiary campus

CHINA: US storage supplier Primus Power has installed a flow battery system at the campus of Goldwind's micro-grid subsidiary Etechwin.

Goldwind will use the modular EnergyPod2 at a site in Beijing, as well as examine how well it works with the manufacturer's turbines.

The system can provide stored power for up to five hours and has been designed for a 20-year lifetime, Primus Power claimed. 

The move comes as local governments in China mull introducing a storage requirement for all new wind projects to help combat the country's high curtailment rates.

According to Primus Power, in 2017 the Qinghai provincial government in northwestern China, "recognised the critical role that energy storage can play to reduce curtailment, and proposed new legislation that would mandate the use of energy storage systems with new wind turbine installations".

Goldwind's product advanced research department lead Guoju Zhang said: "Policy makers in China are considering a mandate that energy storage be incorporated with all new grid-connected wind developments.

"In anticipation of this mandate, we have installed, commissioned and are operating a Primus EnergyPod2 system at our facility.

"With the help of the Primus team, we look forward to proving out the value of battery energy storage paired with our wind turbines," Zhang added.
