Energy storage projects were under construction across four provinces of China, amounting to 340.5MW of new capacity during the first half of this year in the country, according to the China Energy Storage Alliance (CNESA).

Jiangsu, Henan, Qinghai and Guangdong provinces are host to projects that when finished would almost equal the total cumulative capacity of operational energy storage systems in China, which was 389.4MW as of the end of 2017. CNESA, the trade group, also identified four companies that have been especially prolific in the first half of this year.

One ‘project’, actually consisting of eight separate systems at one site in Jiangsu Zhenjiang adds up to 101MW/202MWh of lithium-ion storage systems on the grid-side of the meter and already went into operation in July. Zhenjiang-based company eTrust Power supplied the largest of the eight systems, a 40MW/80MWh battery. CNESA noted that despite only being around since 2016, eTrust has opened seven manufacturing and R&D centres and been awarded a 52.8MWh battery project in Ontario, Canada.
