A 1MW ‘virtual power plant’ part-funded by the Pacific International Center for High Technology Research (PICHTR), utilising energy storage across 29 customer sites, has been connected in O’ahu, Hawaii, by Stem.

The latest step in Hawaii’s clean energy evolution will be the deployment of a 20MW, five-hour duration battery energy storage system paired with 28MW of solar in Kaua’i, to match peak demand with generation.

A company offering solar-plus-storage systems for the residential market has introduced a set of controls that allow consumers to adapt to utility rates and legislative changes with the flick of a switch.

Hawaiian Electric has teamed with Californian storage company Amber Kinetics on a 4-hour duration flywheel energy storage pilot project in Oahu.

Battery manufacturer SimpliPhi Power has released an all-in-one plug-and-play energy storage system to be integrated with on and off-grid solar plants.

EnSync Energy Systems, formerly known as ZBB Energy, announced on Monday the sale of multiple PPAs, including the first ever solar-plus-storage projects sold in Hawaii.

SolarCity has chosen Tesla to supply a 52MWh utility-scale energy storage system, which will make the output of a solar farm in Hawaii dispatchable.

Hawaii has been namechecked as a ‘test bed’ for how grids can migrate to higher levels of PV penetration so often it has become something of a cliché. Stem’s VP for Hawaii operations, Tad Glauthier tells ESN about the projects that are going on, which lessons might be transferable to other regions – and which might not.

A large-scale energy storage system aimed at integrating renewables into electricity networks has been completed on the Hawaiian island of Kaua’i, paired with the state’s biggest PV array to date.

US commercial energy storage provider Stem has deployed its first system in Hawaii, for a pilot project that could help the island state’s main utility reach renewable energy goals “better, and at lower cost”.
