Xcel Energy
KORE Solutions (formerly NRI) was selected by Xcel Energy to design, build and install a battery energy storage system capable of interacting with the grid and continuously supporting a single-phase leg of a local utility power distribution bus. The main objectives for the Stapleton energy storage project are to accommodate more solar energy on the system, reduce energy costs and manage grid issues such as voltage regulation and peak demand. Other benefits include renewable integration and backup power. NRI’s solution was 6 modular energy storage systems comprised of 12 units. Solutions are sized from 69kWh (18kW of bi-directional inverters), 138kWh (36kW of bi-directional inverters) and 207kWh (54kW of bi-directional inverters.) System equipment is housed in an environmentally controlled shelter to protect components from Colorado’s varying weather patterns. The battery is charged and discharged through a grid connection while energy is stored in and distributed from a Lithium-Ion battery bank. - Environmentally controlled shelter & smart battery management system - Long lasting Lithium-Ion battery (Up to 20+ years) - Flexible power distribution - Design can be customized to any application - Designed to operate in hot/cold temperatures - Modular system sizing can adapt and grow for future expansion - Can be programmed to work with other systems or as a standalone unit
