Wind energy to be stored in USA’s largest power storage system

Duke Energy completes North America’s largest energy storage system,
Renewable Energy Magazine Robin WhitlockThursday, 07 February 2013
The 36MW energy storage system will store power generated by the
nearby Notrees wind farm and became fully operational in December

The company announced plans to install large-scale energy storage
systems to service its wind farm at Notrees in late 2009, matching a
$22 million grant from the US Department of Energy (DOE).

As well as helping to meet power demand the system will also help to stabilize the frequency of electricity travelling through the power grid. DukeEnergy is currently working closely with the Energy Reliability Council of Texas (ERCOT) which will indicate whether the system shoulddispatch stored energy to increase frequency or absorb energy to decrease it.  Performance data will be collected from the battery storage system by the Electric Power Research Institute (EPRI) to help assess the broader potential for deployment of storage solutions throughout the sector.

Sandia National Laboratory will meanwhile

analyze technical and economic data. The results will shared
publically through the DOE Smart Grid Information Clearinghouse.

Duke Energy helps to develop innovative wind and solar energy
generation projects throughout the US and its current portfolio to
date includes 15 wind farms and 14 solar farms across nine states with
a total of more than 1,700MW capacity. Currently the DOE Office of
Electricity Distribution and Energy Reliability (OE) is taking on the
responsibility of modernizing the electricity grid while enhancing
security and reliability of the infrastructure. The OE has awarded 16
grants for energy storage projects under the American Recovery and
Reinvestment Act of 2009 (ARRA) worth a total of $185 million. These
projects include diverse technologies such as compressed air energy
storage, flywheels and advanced batteries and applications include
frequency regulation, smoothing of PV installation and ramping for
wind. These are an integral part of the OE’s Energy Storage Programme
and are being project managed by the National Energy Technology
Laboratory (NETL)……
