Kona Brewing Company signed a 20-year power purchase agreement with EnSync, Inc. and its subsidiary Holu Energy to build a solar-plus-battery storage system for a new brewery being constructed in Kailua-Kona, Hawaii. The installation is expected to meet a quarter of the brewery’s electricity needs.
EnSync described the installation as a 336-kilowatt roof-mounted photovoltaic system and an EnSync DER SuperModule that contains a 122 kW-hour battery system to capture and store excess solar generation. Solar power from the project should allow Kona Brewing Company to produce a peak output of 6,875 cans of sun-powered beer per hour.
The project also includes the Matrix Energy Management system, which uses DER Flex Internet of Energy technology to interact with the main grid to find and deliver the lowest-cost, most reliable electricity from multiple sources, according to EnSync.
“By partnering with Holu, we are working with another Hawaiian business to reduce our imported fossil fuel use and create on-site solar energy that helps the state meet its renewable energy goals,” said Julia Person, sustainability manager of Kona Brewing. “This partnership demonstrates how we embrace innovation to maintain our commitment to the ‘Aloha spirit’ and the larger Hawaiian community.”
Adding energy storage to the new brewery will enable Kona Brewing to participate in Hawaiian Electric’s demand response programs, EnSync pointed out. EnSync Energy says its project development and financing helps investors and local energy consumers further the state’s goal to achieve 100% renewable energy by 2025. The DER provider has contracted 26 commercial projects in Hawaii, accounting for more than $40 million in electricity sales.
Construction on the new brewery and canning operation is currently under way on a 2.6-acre site in Kailua-Kona. The Hawaiian craft brewery announced last year that they are investing more than $20 million in a 30,000-square-foot facility.
Kona Brewing is working with PurposeEnergy to create an on-site resource recovery center that will recycle the organic brewing byproducts, extracting the energy potential and reusing it to produce electricity, heat, and clean water for the brewery. The center plus a high efficiency craft brewing system and the solar photovoltaic system will enable Kona Brewing to generate nearly 50% of its energy needs, the brewing company says.
Completion of the solar-plus-battery storage system is targeted for early 2019.
