Wind Powered Battery Storage Pilots in Texas
Duke Energy Renewables has developed a way of saving extra power generated by batteries at its Notrees Windpower Project in Texas. The $44 million battery-storage system holds excess energy from the 153-megawatt Notrees farm and releases it when power supplies dip. This innovation is particularly helpful because winds often blow more strongly at night, when power needs are less, and more gently during the day, when power demands are higher. With this battery storage system, wind generated power can be kept and used, as and when needed, thus stablising the grid. Data from the project is being collected and analysed for scale-up by the US Department of Energy, who helped fund Duke Energy Renewables’ wind power, storage battery.
To date, the project has cost $22 million.
