EnerDel has supplied and commissioned 1440 lithium-ion batteries for an electrical energy storage system. The 5MW smart grid is part of a project in Salem, Oregon run by Portland General Electric (PGE), which itself is part of a larger Pacific Northwest Smart Grid Demonstration Project.EnerDel

The EnerDel system comprises 1440 rack-mounted lithium-ion battery modules, which are monitored by an advanced BMS to support a 5MW inverter array consisting of 20 250kW/62.5kWhr channels rated at 600V.

EnerDel CEO David Roberts said: “EnerDel is excited to be working with PGE to demonstrate how customers can benefit from the use of smart grid systems and technologies that incorporate energy storage for renewable resources, back-up power and peak shaving.”

The battery system supports the larger PGE power system to provide power at times of peak demand or for back-up power in the event of an outage.

“PGE’s decision to integrate renewable energy sources into the grid using EnerDel Lithium-ion technology demonstrates forward thinking and affirms the adaptability of this technology,” added Roberts.
