Fluence Energy, Inc. (NASDAQ:FLNC) is a global market leader delivering intelligent energy storage and optimization software for renewables and storage.

Fluence Energy, Inc. (NASDAQ:FLNC) continued to surge this week after it was revealed that DRI, the EU renewables division of Ukraine’s DTEK Group, has selected the company to supply battery storage units for its 133 MW Trzebinia project in Poland.

Julian Jansen, Managing Director of Growing Markets at Fluence Energy, Inc. (NASDAQ:FLNC), stated:

“Poland has the potential to be one of the five largest European energy storage markets by 2030. We look forward to further investment in our Polish operations and team, supporting grid resilience and energy security across Central and Eastern Europe.”

It must be noted that earlier this month, it was also reported that Fluence Energy, Inc. (NASDAQ:FLNC) is set to provide the technology for two large battery energy storage systems (BESS) projects in Switzerland, with a combined capacity of 58.6 MW.
