World’s biggest battery

World’s biggest battery post by batterylaptoppower.com



Duke Energy Renewables plans to spend $44 million to install a 36-megawatt battery system at its Notrees Wind Project in Texas.





It will be the world’s largest power storage system for a wind farm once it is installed late next year, says Duke Renewables spokesman Greg Efthimiou. It’s also the one of the largest used for any kind of power storage.



Xtreme Power, a manufacturer of large-scale developer of digital power systems based in Kyle, Texas, will design, install and operate the battery for Duke , which is in the process of merging with Progress Energy of Raleigh. Both companies have customers in the Triad



Duke won a $22 million grant from the U.S. Department of Energy to install a large-scale battery at the 153-megawatt Notrees site. Duke matched the grant to fund the project.



The 36-megawatt capacity is massive for a storage battery. It exceeds, for instance, the capacity of Duke’s entire Happy Jack Wind Farm in Wyoming.

Demonstration project



Efthimiou says the battery Dell studio 1555 battery Acer aspire 5920 battery can be used only to supply power for a short amount of time. But its capacity makes it sufficient to provide the equivalent of power to almost 24,000 homes for an hour during times of peak energy demand when the wind dies.



“In addition to supplying stored renewable energy, this battery storage system will be capable of providing other key grid services, including helping smooth out the frequency of electricity traveling throughout the power grid,” he says. “One of the key intents of this energy storage project is to test and demonstrate how that added flexibility can benefit renewable-power projects throughout the country.”



The Electric Power Research Institute will advise the project team and collect data to help assess the potential for use of such storage systems elsewhere. Results from the storage project at Duke Energy’s Notrees wind farm will be shared publicly through the DOE’s Smart Grid Information Clearinghouse.
