A123 Systems to Supply Energy Storage System to Dongfang Electric

A123 Systems landed a contract to supply a 500kW advanced energy storage solution to Dongfang Electric Corporation (DEC), the third largest manufacturer of wind turbines in the People's Republic of China and the country's largest exporter of power equipment. Expected to be installed at DEC's manufacturing facility in Hangzhou city, China Zhejiang Province, by the end of 2011, the system is designed as a demonstration project to help DEC evaluate how advanced energy storage can address the challenges associated with the rapid growth of wind power in China.


"The government has set ambitions goals to increase wind power in China to about 170GW by 2020, and DEC looks forward to doing our part to help reach this target.
However, there will be infrastructure and interconnection challenges along the way that must be addressed," said Mr. He, general manager of Dongfang Electrical Machinery Co. "Advanced storage technology continues to show promise as a potential solution to the variability of wind energy generation, and installing this project with A123 will allow us to gain hands-on experience with grid-scale storage systems. Ultimately, we expect this to help us understand how we can leverage larger-scale energy storage deployments to facilitate the rapid adoption of wind energy across China."

This project will be A123's first energy storage system in China, where only about 72 percent of the country's total wind power generating capacity is connected to the power grid, according to data from the China Power Union. This is largely due to the unacceptable Low Voltage Ride Through (LVRT) capability--during periods of low grid voltage, wind farms are disconnecting and are slow to reconnect when voltage increases--and the general lack of ramp management technology, which results in the inability to predict the output of wind farms and leads to grid instability.

"We believe that China represents a significant market opportunity for our advanced energy storage technology, especially as a solution to addressing the LVRT and ramp-management problems standing in the way of the country's aggressive plans for wind power deployment," said Robert Johnson, vice president of the Energy Solutions Group at A123. "Today's announcement is a significant step toward developing a presence in China, and by aligning ourselves with an established organization like DEC, we believe we will gain a considerable strategic advantage. We are hopeful that DEC will find that our storage systems are optimal for enabling the widespread adoption of wind power, and believe this project could result in additional contracts going forward."
