Powin deal as Hawaii aggressively aims for 100% renewables

Published on: August 10, 2017 9:17 amBy: ESJ

Battery storage company Powin Energy announced on August 2 that it had been chosen by Adon Renewables to provide energy storage systems for a portfolio of seven solar plus storage projects in Hawaii to help the US state cope with its huge distributed energy resources.

With a combined 2.4MWh, the projects will use Powin’s site management software and its Battery Pack Operating System (bp-OS) to provide an array of services including frequency and voltage regulation, local capacity augmentation, emergency services, and load control.

The systems will use Powin’s Stack140 modular — a purpose-built 140kWh battery array that can be scaled up from 125kW to multiple megawatt applications — and be paired with solar PV panels. The complete system will be run by Powin’s bp-OS software.

Hawaii is an important market for energy storage due to the state’s aggressive goal to run on 100% renewable energy by 2045.

Geoffrey Brown, president of Powin Energy, said: “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 charged with excess energy from the solar panels during the day when loads are lightest and utility rates the lowest.

In June, Powin announced it was partnering with Hecate Energy to build, deliver, and install projects, using its Stack140 technology, with a total capacity of 12.8MW/52.8MWh at two sites in Ontario, Canada.
