AES turns on facility using energy storage, wind power

Elkins, W. Va., October 27, 2011 — AES Wind Generation and AES Energy Storage announce the commercial operation of AES Laurel Mountain, a wind generation plant comprised of 98 MW of wind generation and 32 MW of integrated battery-based energy storage. The project is supplying emissions-free renewable energy to the PJM Interconnection.

The 32 MW advanced storage project uses battery technology with storage service provided by AES Energy Storage will help optimize the renewable energy generated.

The project provides PJM with regulation service, delivering instantaneous response to grid operator requests for power, helping to match generation and demand. The storage also allows the wind facility to control the ramp rate of its generation, smoothing out fluctuations in minute to minute output.

AES Laurel Mountain consists of 61 GE 1.6 MW wind turbine generators capable of a combined power generation of 97.6 MW and 32 MW of A123 Systems energy storage devices.

The 61 wind turbines are mounted on 80-meter towers deployed along a 13-mile stretch of Laurel Mountain located in Randolph and Barbour counties near Elkins, West Virginia. The facility will supply more than 260,000 MWh of emissions-free, renewable energy each year to the PJM Interconnection.
