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.
Distribution operator UK Power Networks announced on January 23 it is to launch four vehicle-to-grid (V2G) projects to demonstrate how electric vehicles can be used for peak shaving and possibly deferring reinforcement costs. The projects, in the south east and east of England as well as London, will look at how the technology can read more
US energy storage firm ViZn Energy Systems has appointed Stephen Bonner as the president and interim CEO of the zinc iron flow battery, the company announced on January 26. Bonner, who was named chairman of its board of directors on January 1, assumed the additional roles following the resignation of Ron Van Dell, who read more
Installations of PV plus battery systems have risen by 1,830% on the Hawaii island of Oahu helped in part to falling prices, according to a report from the state’s department of business economic development and tourism released on January 31. The report, based on building permit data released by the Honolulu Department of Planning read more
Energy storage start-up Arenko announced on February 5 that it had chosen General Electric to deliver a 41MW lithium ion energy storage system to ensure security of supply to 100,000 UK homes. The strategic alliance will combine GE’s technology with London-based Arenko’s experience of the UK market as well as its proprietary energy trading read more
South Australia’s adoption of the latest technology to address its energy problems will involve a trial of virtual power plants and installation of a 4.3MWh lithium ion micro-grid, its government announced in early February. The state’s energy minister Tom Koutsantonis said the South Australian Produce Market would install 2.5MW array using 1,600 solar panels read more
