Powin Energy to Deploy 2.4 MWh of Energy Storage Systems Across Seven Site Solar Plus Storage Portfolio in Hawaii

August 6, 2017 | News Brief | Powin Energy, a provider of fully integrated energy storage solutions for utility, commercial, industrial, and microgrid applications, has been selected by Adon Renewables to provide energy storage systems for a portfolio of seven solar plus storage projects in Hawaii. Each site will store solar energy not used during daylight hours and then discharge that energy for the customers use each evening when the sun goes down. Over time, Powin and Adon Renewables will leverage Powins site management software and its Battery Pack Operating System (bp-OS) to provide a wide array of services to both the onsite customer and the utility. These services may include frequency and voltage regulation, local capacity augmentation, emergency services, and load control.

Hawaii is a very important market for energy storage because of the states aggressive goal to run on 100 percent renewable energy by 2045, so were pleased to have built this partnership with Adon Renewables and secured the first of what we hope to be many projects with them on the islands, said Geoffrey Brown, president of Powin Energy. The state has already installed a large amount of solar both residentially and commercially, but all of these distributed resources have created an urgent need for energy storage to maintain system frequency and voltage as well as energy shifting from daytime to peak periods in the evening when it is needed most.

Each Powin Energy Stack140 storage system will be coupled with solar PV panels and will be controlled by Powins bp-OS that was patented in both the US and China in 2016. The batteries will be charged with excess energy from the solar panels during the day when loads are lightest and utility rates the lowest. The batteries will then be fully discharged each evening to provide additional power during periods of increased grid load, thus allowing the facilities to avoid the highest rates.

The initial seven sites feature prominent customers such as the iconic Boy Scouts of America and marquee resort property Aqua Kauai Beach Resort.

Powin Energys Stack140 is a modular, purpose-built 140 kWh battery array that scales from 125 kW to multiple megawatt applications. It is available in both indoor and NEMA 3R outdoor models, each of which is engineered to maximize energy density and minimize system footprint. All Stack140 systems are operated by Powins bp-OS software that includes the Battery Odometer and Warranty Tracker.
