The rooftop photovoltaic system on the Aloha Tower Marketplace is being expanded to more than double its capacity. The PV system is operated by Hawai'i Pacific University (HPU) under a lease with the State of Hawai'i Aloha Tower Development Corporation. Once complete, the newly expanded system will produce 660 kilowatts (kw), making it the largest solar installation in downtown Honolulu.
EnSync Energy will add 350 kw in PV capacity to the system under a 20-year power purchase agreement (PPA) it signed with HPU and an undisclosed investor. The solar energy will power HPU's revitalized Aloha Tower Marketplace, a mixed-use space featuring university student residences, community spaces, restaurants and shops.
EnSync Energy designed the system based on customized analysis of Aloha Tower Marketplace's current energy consumption patterns and anticipated future energy needs. After conducting energy and price modelling, EnSync Energy found that a grid-ready PV installation would yield the most savings for the University.
Construction of both phases is expected to be completed by early 2019. HPU may consider a third solar installation phase under the terms of the PPA.
