Energy storage solutions company Powin Energy says it has been selected by Adon Renewables to provide 2.4 MWh of energy storage systems for a portfolio of seven solar+storage projects in Hawaii. According to Powin, the projects feature prominent customers such as the iconic Boy Scouts of America and marquee resort property Aqua Kauai Beach Resort.
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 an 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 state’s aggressive goal to run on 100 percent 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,” says 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, which was patented in both the U.S. 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, according to Powin.
“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,” says 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 roll-out of a large portfolio of projects with Powin.”
