Fowler Ridge Wind Farm in Indiana

Fowler Ridge Wind Farm

Project sponsors expanded a wind farm on a 54,880-acre site near Fowler, Indiana in Benton County. Most of the site is open farm land, therefore, impacts to wildlife were expected to be minimal. However, wind turbines routinely kill bats and even on this open agricultural site, wind turbines have killed Indiana bats (an endangered species). Therefore, project sponsors applied for and received an "Incidental Take" permit. The permit allows "take" of Indiana bats that may result from normal operation of the wind farm. To receive the permit, project sponsors prepared a Habitat Conservation Plan (HCP), which details measures to minimize "take" of Indiana bats and to mitigate the "take" that cannot be avoided.


Project sponsors are BP Alternative Energy North America Inc., Sempra Generation, and Dominion Resources, Inc.


Project sponsors of the Fowler Ridge Wind Farm in Indiana applied for and received an incidental take permit for Indiana bats. Under the Endangered Species Act companies may obtain a permit that allows limited take of threatened or endangered animals, provided an approved habitat conservation plan is in place. To receive an incidental take permit for Indiana bats at its wind energy facility, Fowler Ridge must follow the approved habitat conservation plan designed specifically to reduce impacts to the Indiana bat.


The habitat conservation plan developed by Fowler Ridge includes measures for the long-term conservation of Indiana bats. The Fowler Ridge Wind Farm currently includes 355 wind turbines in Benton County, with plans for up to 94 additional turbines. Two occurrences of Indiana bat mortality have been discovered and reported by Fowler Ridge during surveys at the facility.


HCP Monitoring Reports

The primary objective of monitoring is to determine if the minimization measures reduce mortality by 50% or more compared to turbines that operated normally (without minimization measures) in 2010.
