ZBB Energy signed a 20-year power purchase agreement (PPA) with University of the Nations on the Island of Hawaii for the installation of a 408 kW PV system with Agile Hybrid batteries, and accompanying Matrix electronic power controls. The power plant is expected to result in more than $2.4 million in energy savings over the lifetime of the PPA.
ZBB’s Agile Hybrid Battery storage system combines the energy characteristics of a zinc bromide flow battery with the power characteristics of lithium ion storage batteries.
ZBB says it implemented the PPA model into its portfolio to provide customers with savings in electricity and to provide its company investors an instrument that generates a high financial rate of return over a long duration.
Founded in 1978, University of the Nations is a Christian university with branches in 600 locations in more than 140 countries. Its campus in Kona, Hawaii, is one of its largest. The installation is scheduled for completion in two phases beginning in the fourth quarter of 2015.
