    Wisconsin firms, utility commission Wyoming energy storage system

    Two Wisconsin companies are teaming up on a smart grid demonstration project for a utility in western Wyoming.

    The utility, Lower Valley Electric Cooperative, worked with Facility Gateway Corp. of McFarland to commission an energy storage system built by ZBB Energy Corp. of Menomonee Falls.

    Facility Gateway provides services for data centers that include finding ways to make them more energy efficient. ZBB is a developer of power electronics and energy storage systems.

    The Wyoming project aims to combine solar and wind power generation with utility-scale lead acid batteries, integrated with the ZBB system. The goal: to help overcome the variable output of renewable energy systems, said Warren Jones, Lower Valley distribution engineer, in a statement.

    The bank of batteries will be used to help provide power output during times of peak power demand, he said.

    For Menomonee Falls-based ZBB, the project offers it a chance to prove its technology can work in conjunction with utilities, as well as at customers that seek to generate all of their own power on-site.

    The use of lead-acid batteries rather than ZBB’s zinc-bromide flow batteries “demonstrates that the ZBB EnerSection can work with multiple types of storage and that no one storage type is the definitive product for all applications and markets,” ZBB chief executive Eric Apfelbach said in a prepared statement.
