Case Study: Solving Installation Challenges During COVID-19 Pandemic

NRG is well-versed in navigating global projects, but when COVID-19 brought the world to a halt in March 2020, unforeseen challenges with travel, training, and installation emerged.

Developing an Ultrasonic Acoustic Bat Deterrent System for the Wind Industry

Wind turbines have been shown to cause direct mortality to bat species, with bat deaths documented at wind energy facilities around the world. Building upon insights from nature and a great deal of previous research, NRG Systems developed its Bat Deterrent System to mitigate the wind industry's impact on bats. This white paper provides an overview of the development of this pioneering solution.

Efficacy of Acoustic Deterrence for Bat Occupancy of Highway Structures

In the following white paper, ICF discusses the use of acoustic deterrence to minimize harm to roosting bats at bridges. The paper covers a series of studies performed by ICF biologists for the Georgia Department of Transportation (GDOT) using NRG Systems’ bat deterrent technology.

Exploring How Attenuation Affects NRG Systems’ Bat Deterrent System

Certain environmental conditions contribute to the loss of sound over distance – a phenomenon known as attenuation – which can impact the effective range of the NRG Systems' Bat Deterrent System. 

First European Trial of NRG's Bat Deterrent System Shows Promising Results

In 2019, ENGIE Laborelec conducted the first European trial of NRG’s Bat Deterrent System at a wind plant in Belgium. The promising results are outlined in a white paper available on the company's website. 

NRG Success Story: Digi Technologies – Advancing Vietnam’s Renewable Energy Transition

NRG Systems supplied longtime customer, Digi Technologies, with advanced SymphoniePRO data logging systems and highly accurate meteorological sensors for wind resource measurement systems deployed on behalf of Nexif Ratch Energy, advancing Vietnam’s renewable energy sector.

NRG Success Story: Inter-Domain – Overcoming Installation Challenges in Remote Japan Sites

Longtime customer, Inter-Domain, installed three 60m XHD TallTowers to support resource assessment campaigns at diverse wind sites, each with challenging conditions.

Post Calibrating the 40C Anemometer in the SOH Wind Engineering (SOH WE) Wind Tunnel

Two procedures – one simplified, one rigorous – are provided in this white paper, defining the process of evaluating SOH WE post-calibrations of 40C Anemometers initially calibrated at Otech.

Summary of Cup Anemometer Classification - WindSensor P2546A-OPR + P2546C-OPR

Danish Technical University (DTU) Wind Energy Department has classified the WindSensor P2546A-OPR anemometer in compliance with the procedures outlined in IEC 61400-12-1:2005 Annex I.
