Advancion advances

1 February 2016



AES reports entry into commercial operation of 10 MW battery- based energy storage arrays in the Netherlands and in Ireland (at Kilroot power station, where it will enhance grid reliability by providing fast response ancillary services like frequency regulation). The arrays employ Advancion 4 technology, which AES describes as a “low-cost battery-based alternative to traditional peaking power plants and pumped hydroelectric storage projects that provides a dependable, smart and cost-competitive means to modernise power systems.”


With completion of these two projects, AES says it has now worked on battery storage in eight different power markets and its storage fleet now totals 116 MW with 3 million MWh of delivered service. AES has also announced construction or late stage development of an additional 268 MW of energy storage.

The company is offering the Advancion 4 energy storage technology for sale to "utilities, power markets, renewable developers, and independent power producers." It claims it "introduced the first grid- scale advanced battery-based energy storage solution in commercial power market service," in 2008, and "operates the largest fleet of battery-based storage assets in service today."

The Arrays employ over 53 000 individual cells, arranged in 136 separate nodes for increased reliability, and the patented Advancion control system, which responds to grid changes in less than a second.

The impact of the Kilroot array on the grid is to be analysed as part of project funded by Innovate UK Energy Catalyst, in partnership with Queen's University Belfast, to demonstrate the full capabilities of energy storage.

The 10 MW Kilroot array is a first step towards a planned 100 MW energy storage facility at the site. The first deployment of Advancion 4 was last year, at the Warrior Run facility in Cumberland, Maryland, USA, where AES worked with its initial certified suppliers, LG Chem and Parker Hannifin. The Warrior Run installation will provide critical grid stability services in the form of frequency regulation service to the PJM Interconnection.

Key features of Advancion 4 include: compactness; scaleability and modularisation, with standard configurations ranging from 100 kW to over 1000 MW, and from 15 minutes duration to over four hours without any re-engineering; and advanced digital control with ability to monitor a very large number data points (80 000 in the case of Warrior Run).
