EchoSense® (formerly DARC) bat smart curtailment technology provides an alternative to the high energy losses associated with blanket curtailment by simultaneously reducing curtailment hours, energy loss, and bat fatalities at wind farms.
EchoSense® was developed by a team of bat experts and technology and software engineers as a more effective way to protect bats with minimal impact on energy production when compared to blanket curtailment strategies.
EchoSense® has been in development since 2018.
Jim Adams, president of North America operations, said: “What we were trying to solve was a complex puzzle across multiple disciplines. It required a deep understanding of bat behavior and interplay of different curtailment strategies on power generation.”
How EchoSense® works
The video below gives you an idea of how DARC works using SCADA data, meteorological data and the acoustic data to curtail wind turbines when bats are present.
How we tested EchoSense® to prove its effectiveness
Following a proof-of-concept deployment in 2019 and supported by the U.S. Department of Energy (DOE) as well as the National Renewable Energy Laboratory (NREL), we worked with Alliant Energy to install and operate a full system from August to October 2020 at the English Farms wind farm in Iowa.
We tested EchoSense® against minimal and blanket curtailment to prove it works, and EchoSense® is proven to increase wind energy output at wind farms.
