    Hinesburg, VT, USA - A trial of NRG Systems' Bat Deterrent System at the Pilot Hill Wind Project in Illinois yielded an overall reduction in bat fatalities of 67 percent, and greater reductions with species commonly affected by wind projects. The results of the trial were announced on March 27, 2019, by EDF Renewables, the developer/owner of the Pilot Hill Wind Project, at the AWEA Wind Project Siting and Environmental Compliance Seminar in Albuquerque, New Mexico. Located in Kankakee and Iroquois counties, the 175MW Pilot Hill Wind Project was made possible by a 20-year power purchase agreement with Microsoft Corporation and has been in commercial operation since 2015.

    Testing of NRG's ultrasonic acoustic Bat Deterrent System was conducted at Pilot Hill between August and October of 2018. Fifteen out of the facility's 103 turbines were outfitted with Bat Deterrent Systems. A 5.0 m/second cut-in speed curtailment was simultaneously applied at the deterrent-equipped turbines. Michael Azeka, Director, Environmental Strategy at EDF Renewables, said, "Our goal with this trial was to gauge the efficacy of combining curtailment with NRG's Bat Deterrent System to reduce bat mortality at wind turbines. The results of this trial are very encouraging and suggest that this approach to minimizing bat impacts is a compelling one for the wind industry." There are several bat species present at Pilot Hill, including multiple migratory tree species. The testing revealed a significant reduction of 72% with Silver-haired Bats, 71% with Hoary Bats, and 94% with Big Brown Bats. Eastern Red Bats proved harder to deter, with 58% reduction in mortality for the two treatments together. 

    At the moment, raising cut-in wind speed is the most widely used method for reducing bat mortality at wind turbines. While effective, many wind plants in North America experience a significant loss of energy production when this curtailment is implemented. Brogan Morton, Senior Product Manager at NRG Systems, said, "The Pilot Hill trial is especially encouraging because it suggests that we can minimize bat impacts while increasing the amount of energy produced at wind plants struggling with this crucial issue. This is a win for all parties involved, including developers, conservationists, and, most importantly, the planet."

    The Pilot Hill trial was preceded by a two-year study at the Los Vientos Wind Energy Facility in Texas, which saw an overall reduction in bat fatalities of 54 percent. NRG's Bat Deterrent System is currently available in North America. The company plans to hold trials of the technology in Europe in 2019.

    Hinesburg, Vermont, USA - NRG Systems, Inc., a designer and manufacturer of smart technologies for a range of wind, solar, and meteorological applications, has announced that it will now sell and support ZX Lidars in North America. This will include the ZX 300 for onshore vertical profiling applications and the ZX 300M for near-shore or platform-based offshore applications. Both models capture finance-grade wind measurements from 10 to 200+ meters and are fully IEC classified and accepted by DNV GL as Stage 3 Bankable Lidars.

    NRG Systems, a global leader in wind measurement, offers the industry's most complete portfolio of resource assessment technologies, including met mast systems, Direct Detect Lidar, and Dopplar Lidar. David Hurwitt, NRG's Vice President, Global Marketing and Product Development, said, "We're very excited to pair ZX's proven technologies with our sales, logistics, and service capabilities. The combination gives our customers absolute confidence that we can meet their complete measurement needs."

    NRG Systems was one of the first companies to venture into remote sensing for wind more than a decade ago. Today, they offer a suite of support products and services to facilitate an optimal Lidar ownership experience. Ian Locker, Managing Director of ZX Lidars, said, "More than 36 years ago NRG changed the way wind resource assessment was done. Today, with the addition of ZX Lidars to their product family, it's another milestone in that change. Our Lidars are both technically and financially accepted. They are rugged and robust. And now they are totally accessible and supported in the US and Canada by the team at NRG."

    To support the sale of ZX 300 and ZX 300M units, NRG will also offer custom power solutions, validation services, monitoring services, and inspection and update services. Please visit NRG Systems at the WindEurope Conference & Exhibition, April 2-4 in Bilbao, Spain, and the AWEA WINDPOWER Conference & Exhibition, May 20-23, in Houston, Texas, USA, to speak with a representative in person, or contact for more information.

    About ZX Lidars (formerly ZephIR Lidar)

    ZX Lidars provides industry-leading wind Lidar products, ZX 300, ZX300M and ZX TM for wind energy and meteorological applications. These Lidars deliver accurate wind measurements in both onshore and offshore applications at measurement heights/ranges across the full swept area of the blades of modern wind turbines, and beyond. With more than 10 million hours of operation in the field and over 1,000 deployments (and counting), ZX Lidars has pioneered the use of Lidar in the wind industry. The company is proud of the many world firsts it has achieved with customers including: upwind measurements from a turbine nacelle, turbine wake studies, offshore deployments of both fixed and floating wind Lidar, an industry-accepted validation process, re-financing and re-powering of a wind farm, successful demonstration of measurement accuracy in a wind tunnel and total wind project financing from a Lidar without need for a met mast.

  • NRG Bat Deterrent Systems
    As bat populations across the globe continue to decline, the need to protect these animals is vital. NRG Systems' Bat Deterrent Systems allow wind plant operators to support bat conservation while producing more renewable energy more of the time....

  • The Bat Deterrent Systems emit an ultrasonic acoustic field in the same range as bats' natural calling frequencies. When a bat enters the airspace where the deterrent units are operating, the ultrasound from the deterrent units will be louder than the echo return the bat is listening for. This effectively "jams" the bat's ability to hear its own return. If the bat cannot hear the echoes, it is unable to successfully forage and orient itself, so it chooses airspace without the ultrasonic noise and away from the turbine's rotor swept zone.

    Bat Deterrent Systems are currently commercially available in North America, with plans to hold trials of the technology in Europe in the near future. 

  • Spidar Vertical Profiler - Complete Lidar Solution
    Spidar is a complete remote sensing solution backed by NRG's global partner network, technical support, remote power supplies and integrated services for seamless installation and operation....

  • Our decade-long remote sensing journey has led us to Spidar, a flexible, highly mobile Direct Detect Lidar that can lower the cost and measurement uncertainty of your campaigns.

    Spidar uses Pulsed Direct Detect Lidar technology to provide bankable wind measurement data at 10 vertical heights from 30m to 150m. The low-cost remote sensor is ideal for wind resource assessment, wind farm operations, forecasting, and research. Spidar has the smallest cone angle of any remote sensor in the wind industry, so it can be sited closer to potential obstacles such as buildings and trees. It is also compact and highly portable. This allows Spidar to measure in locations where met towers are not viable due to terrain complexity or permitting constraints.

    Key Benefits:

    • Advantages of remote sensing at a lower cost than other Lidars and lattice towers
    • Available in all regions via NRG's Global Value Added Reseller Network
    • Comprehensive technical support and integrated services for all project development stages
    • Turnkey installations that meet project-specific needs, including remote power supplies
    • Performance verifications carried out by leading consultants
