Powin Energy to deploy 2.4 MWh of energy storage systems across seven site solar plus storage portfolio in Hawaii


Powin Energy, a leading next generation provider of fully integrated energy storage solutions for utility, commercial and industrial, and microgrid applications, announced today that it has been selected by Adon Renewables to provide energy storage systems for a portfolio of seven solar plus storage projects in Hawai’i. Each site will store solar energy not used during daylight hours and then discharge that energy for the customer’s use each evening when the sun goes down. Over time, Powin and Adon Renewables will leverage Powin’s site management software and its patented 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.

Powin Energy will be exhibiting at the upcoming Energy Storage North America (ESNA) conference August 8-10 in San Diego, California, in Booth #237

“Hawai’i is a very important market for energy storage because of the state’s aggressive goal to run on 100% renewable energy by 2045, so we’re 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 Powin’s bp-OS that was patented in both the United States 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.

“We looked at numerous energy storage systems and Powin Energy is clearly a step ahead of the pack with their bp-OS that gives insight to the system that other battery management software doesn’t provide,” said Michael Chen, President of Adon Renewables. “This combined with their leadership team’s renewable and distributed energy resource expertise gave us the confidence to plan the rollout of a large portfolio of projects with Powin.”

Powin Energy’s Stack140 is a modular, purpose-built 140 kWh battery array that easily and cost-effectively 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 Powin’s proprietary bp-OS software that includes the industry-exclusive Battery Odometer and Warranty Tracker™. Powin’s supply chain expertise, modular design, and software proficiency streamline installation and make integrating energy storage into projects pain free.
