TIMRSM | FAQQ. Can I use any bat detector with TIMRSM?
Q. Can I deploy this on any turbine model?
Q. Is customization required to deploy TIMRSM?
Q. Is the risk model used at the test site applicable everywhere? Is it necessary to build risk models at new sites?
Q. If I need or want to build a custom model what is the process?
Q.Can TIMRSM be used offshore?
Q. Can TIMRSM be used outside the United States?
A. No. The TIMRSM smart curtailment system requires more than a bat detector. It also requires real-time acoustic file processing and communication systems. The ReBAT bat detection system has this expanded functionality. [TOP]
A. Yes. We have deployed ReBATs on a variety of turbines, including GE and Vesta. We have used several methods (e.g., direct, standoffs, and booms) to attach the microphones to the nacelle. [TOP]
A. Yes. The communication hardware and protocol need to be customized to interface with the project-specific infrastructure. However, Normandeau has experience customizing common communication protocols such as Modbus and DNP3. For some facilities, it is also advantageous to build a custom prediction model (see next question). [TOP]
A. The premise of the model—curtailing wind turbines during times of low wind speed and high bat activity—is well supported by other studies (Arnett et al. 2011; Arnett et al. 2013; Baerwald et al. 2009). Because the model has been tested at only one location, it is uncertain how portable this model is to other sites. [TOP]
A. Ideally the custom model would be based on a year of bat activity and bat mortality data so that the relationship can be explored and modeled. Once the TIMRSM system is implemented, bat mortality data will be collected to validate that the system has reduced fatalities and optimized operations. [TOP]
A. Yes. Offshore deployment is similar to an onshore deployment. Generally the costs can be higher because the marine environment increases the rate of deterioration of the microphones, which will require periodic replacement to maintain sufficient sensitivity. [TOP]
A. Yes. Patterns of bat fatalities in Canada and Europe are similar to those in the United States, and studies in Europe have demonstrated similar reductions in bat fatalities. [TOP]
The TIMRSM smart curtailment system was the result of collaborative research sponsored by the Electric Power Research Institute, Inc. Watch the video.
