  • ESS Tech Inc. signed a Letter of Intent with Juniper Energy LLC to deploy 500 MWh or more of sodium-ion battery energy storage systems.
  • The partnership framework includes an initial 10 MW / 80 MWh project in California targeting commercial operation in 2027.
  • The initial California project will utilize ESS's modular sodium-ion AC solution, Bridge™, along with an ESS Energy Management System.
  • Juniper Energy intends to procure 500 MWh or more of ESS battery systems by 2032, subject to successful project execution.
  • ESS's sodium-ion technology utilizes abundant materials to reduce exposure to geopolitical supply chain risks and Foreign Entity of Concern restrictions.
