(Yicai) Sept. 30 -- Eve Energy has almost doubled in value this year after its shares jumped today on news that the Chinese lithium-battery maker has struck partnerships with two European firms to deepen its push into the region’s energy storage market.

Eve Energy [SHE: 300014] closed up 8.8 percent at CNY91 (USD12.80) per share in Shenzhen today, taking the stock’s year-to-date gain to 95 percent.

Ever Energy signed a partnership deal with TSL Assembly, a renewable energy provider in central and eastern Europe, to deploy one gigawatt-hour of energy storage systems between next year and 2030, supporting market expansion and the regional green energy transition, the Huizhou-based firm announced today.

TSL has established sales networks and project expertise in Slovakia, the Czech Republic, Hungary, and neighboring countries, the press release noted. 

Under the agreement, Eve Energy will supply advanced energy storage systems and battery module solutions, supported by its German office, which will provide technical and project services to ensure implementation.

In a separate statement, Eve Energy also announced a 500-megawatt-hour deal with Polish solar systems operator CommVolt. The companies plan to build benchmark storage projects in central and eastern Europe to better match products to market needs while enhancing grid stability and renewable energy absorption, it said.

Last year, Eve Energy ranked ninth worldwide for installed capacity of electric vehicle batteries and second for the energy storage segment, according to South Korean market research and consulting firm SNE Research.

Eve Energy’s first-half earnings report showed its sales network now spans a dozen countries across Europe, the Asia Pacific, and North America. Overseas revenue reached CNY7 billion (USD982.9 million) in the six months ended June 30, accounting for nearly a quarter of total sales.

The company opened its first overseas plant in Malaysia in February and is building a second in Hungary, which is expected to begin operations in 2027.
