Technology Innovation

Hatchet Ridge, Pattern Energy

REWI’s cutting-edge work in Technology Innovation is a catalyst and expert forum for the development of advanced technologies to avoid and minimize the impacts of wind energy on wildlife. These critical solutions enable maximizing power production and facilitating the expansion of wind energy while improving conservation outcomes.

About Technology Innovation

The Challenge: Verifying Results

Technologies can provide solutions to avoiding and minimizing risk from wind energy operation to wildlife.

Yet the technologies available or being developed are few, and of those that have undergone independent testing, only limited results are available. Given the expense, time, and uncertainty associated with use of these technologies, regulators and wind energy companies are hesitant to use them without knowing their effectiveness. Testing technologies at multiple facilities will verify effectiveness in diverse environmental conditions and establish statistically robust data from which to draw conclusions.


The Approach: Technology to Minimize Impacts

Technologies can avoid or minimize wildlife collisions with wind turbines through one or more of the following components:

  • Detect approaching wildlife using cameras, radar, thermal imaging, or acoustic monitoring with sophisticated software or artificial intelligence.
  • Curtail (automatically shut down) wind turbines when risk of collision is determined to be high for key species based on environmental factors or based on detection by a detection technology.
  • Deter wildlife from approaching or draw the animal’s attention to the turbine by deploying audible or visual deterrent signals.


The Solution: Technology Innovation and Evaluation

REWI engages with researchers to conduct scientific evaluations of emerging and available technologies at commercial wind energy facilities, raises project funding, and oversees the design and execution of the tests to ensure that results can be compared across multiple projects and are scientifically rigorous.


  • Promotes transparency by ensuring test and evaluation results are peer-reviewed and made public by publishing results online and in scientific journals.
  • Coordinates with the U.S. Fish & Wildlife Service and state wildlife agencies to ensure evaluations are carried out with their insights and input considered.

By pooling resources and expertise from wind industry partners, REWI can coordinate and replicate rigorous verification studies, leading to more rapid and widespread adoption of successful technologies.


Broadening the Reach of Technology Innovation

REWI is working to expand the reach and increase awareness of technology innovations through outreach and strategic partnerships, such as through collaboration with the National Renewable Energy Laboratory and EPRI. To promote both industry adoption of technologies and acceptance from broader stakeholder groups, REWI will share objective, reviewed results and findings. Upcoming outreach activities include webinars and seminars for different stakeholder groups focusing on the bridge between technology, end-users, and biological objectives.

REWI Technology Evaluation Projects

Completed Evaluations


Current Evaluations

DOE-Supported Eagle Technology Projects

In 2017, REWI was awarded funding from the U.S. Department of Energy for further evaluation of IdentiFlight and DTBird. The technologies are being evaluated over several years at multiple operational wind facilities in collaboration with scientific researchers, technology developers, and members of the wind industry. Both projects are underway.

Bat Technology Evaluations

ERWI is evaluating risk minimization technologies and strategies for bats. These projects, which include funding from the U.S. Department of Energy, include evaluations of ultrasonic acoustic deterrents and smart curtailment technologies and strategies intended to optimize production and reduce risk for bats.
