China’s Longi Green Energy Technology Co. plans to buy a majority stake in a local energy storage maker, joining its domestic rivals in seeking a new growth engine as the oversupplied solar sector struggles with losses.

The company aims to take a 62% share in PotisEdge, a lithium-ion battery maker, according to a filing on a government website. The statement did not give details on the size of deal.

The move comes amid booming demand for energy storage both in China and abroad, as power grids evolve to accommodate rising renewable penetration. Other major solar manufacturers in China, including Trina Solar Co. and Jinko Solar Co., have already expanded into the sector.

Longi’s net loss narrowed in the latest quarter after the firm took multiple cost-reduction measures. Chairman Zhong Baoshen said in September the company is “confident” it will return to breaking even in its core business in the fourth quarter.
