HAYWARD, Calif., April 01, 2018 (GLOBE NEWSWIRE) — Primus Power (“Primus”), the leading long duration stationary energy storage company, announced today that Etechwin is operating an EnergyPod 2 at their Beijing campus. Etechwin is the microgrid subsidiary of Goldwind, a world-leading wind turbine manufacturer.
The curtailment on wind energy is a significant economic problem, especially in western China. As stated by Bloomberg, “drawing upon data from China’s National Energy Administration, Bloomberg New Energy Finance recently estimated that owners of China’s wind and solar assets forewent approximately $4.7 billion in potential revenue due to curtailment in 2017.” In June 2017, the Qinghai province recognized 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.
Battery energy storage paired with wind turbines unlocks the ability to mitigate rapid wind output changes due to varying wind speeds and helps ensure a stable power output, and controlled ramp up and ramp down of the wind power generation [link]. Wind plus storage also provides electric grid operators the ability to time shift power generation to periods of high demand and provides frequency control to ensure a stable grid.
“Policy makers in China are considering a mandate that energy storage be incorporated with all new grid connected wind developments,” says Guoju Zhang, Goldwind’s Product Advanced Research Department Chief. ”In anticipation of this mandate, we have installed, commissioned and are operating a Primus EnergyPod 2 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.”
“Primus is excited to be working with Goldwind and Etechwin to help solve the challenges represented by renewable curtailment,” remarked Jorg Heinemann, Primus Power’s Chief Commercial Officer. “Both Goldwind and their customers will greatly benefit from the multi-hour performance and multi-decade life that our EnergyPod 2 provides. Our friends at Goldwind and Etechwin are strong partners, and we look forward to continuing our partnership on future projects”.
