Businesses and organizations throughout Hawaii are about benefit from 2.4 megawatt-hours of solar-plus-battery systems at 7 locations, thanks to a partnership between Powin Energy and Adon Renewables. Powin Energy will install its Stack140 storage systems at 7 locations, which include the Aqua Kauai Beach Resort and the Boy Scouts of America.
“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,” said Geoffrey Brown, president of Powin Energy.
Powin’s modular Stack140 storage system is a 140 kilowatt-hour battery array that is scalable from 125 kilowatt-hours and easily installed and linked to create larger megawatt capacity systems. The system can be installed indoors or in 20 to 40-foot containers outdoors. The Stack140 is operated by the company’s bp-OS energy management software platform to efficiently maximize energy load shift from day to nighttime hours.
Powin’s battery storage system will compliment the Aqua Kauai Beach Resort’s 592 kilowatt solar array built on the resort’s guest parking structures. Through its Green Initiative, the resort has implemented energy efficiency measures, like LED lighting and installing an energy efficient air-conditioning system which uses 52 percent less electricity to operate.
“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,” said Brown.
Hawaii has one of the most proactive renewable energy plans in the US and continues increase the diversity of energy generation throughout the islands. For instance, the largest utility in the state, Hawaiian Electric Companies (HECO), announced that it has plans to power its service area with 100 percent renewable energy by 2045. HECO will start toward achieving this goal by developing 110 megawatts of utility-scale solar by 2019 and doubling rooftop solar installations from 79,000 systems to 165,000 arrays by 2030.Tweet
