Professional Installation and Documentation:
Tilt-up Tubular Towers
For nearly 30 years, NRG Systems has been a trusted manufacturer of met tower equipment. The creator of the original tilt-up tubular tower, NRG's TallTowers are known for their sturdy, durable design.
TÜV SÜD provides NRG System 30, 50, and 60 meter tilt-up towers that are pre-configured with industry-standard data loggers and sensors. We offer a complete, cost-effective installation, and maintenance package of NRG towers to meet your project's specific needs.
NRG's 60 meter tower is perhaps the most common wind resource monitoring equipment used throughout the industry.
NRG met tower benefits:
- Positive, Long-Standing Reputation: Since 1982, NRG has led the industry in met tower manufacturing. NRG’s tried and true met tower products can be found in more than 120 countries, serving a wide clientele of developers, utilities, research institutes, government agencies, and universities.
- Extreme Weather Survival: Tilt-up towers, because of their galvanized steel tube construction, can withstand the most extreme weather conditions. They even exceed EIA-222 F Standards.
- Easy Transportation and Installation: The steel tube structure is lightweight and comes in sections, making for easy installation and transportation. The sections slide together and tilt up from the ground using a ginpole and winch. Aircraft cable guy wires support the towers and are secured with standard screw-in anchors. No climbing, cranes, drills, or concrete foundations needed.
Lattice Tall Towers
 As hub heights of wind turbines increase, there is a greater industry need for 80 to 100 meter meteorological measuring equipment. Measuring wind data at the height of turbine operation increases the accuracy of energy production estimates and reduces the uncertainty of extrapolating data from shorter towers.
For wind projects with high wind regimes that might necessitate the usage of large turbines, installing an 80 meter - 100 meter met tower might be the answer you are looking for.
TÜV SÜD provides 80 and 100 meter lattice towers with comprehensive installation and maintenance packages. Our team is skilled and efficient in 80 and 100 meter installs. All 80 and 100 meter towers are equipped with industry-standard data loggers and sensors.
The durable, lattice structure of these towers provides many benefits:
- Data Collection at Turbine Hub Heights: Taller 80-100 meter towers collect data at the height at which most wind turbines operate today. This guarantees that data collected from these towers will directly correlate with the conditions your project's turbines will experience.
- Simple, Low-Cost Maintenance: Because of their sturdy lattice structure, these towers allow instrumentation maintenance via tower climbers. Climbing an 80 meter tower is much more convenient and cost effective than the overall price of lowering and re-raising towers to perform regular maintenance.
- Easy Transportation: Lattice structures are lightweight and come in small, stackable sections, making them easy to transport.
Remote Sensing Equipment - SODAR
The next generation of wind assessment hardware may be tower-less. Several studies have shown that SOund Detection And Ranging (SODAR) is an effective way to assess a wind resource at today's turbine heights. It is quickly becoming the preferred choice of assessment among prospective wind developers. In fact, a recent study conducted by the National Renewable Energy Laboratory shows that data collected by the Triton is equally valid as data collected from tradition met towers. Take a look at the study here.
SODAR systems, unlike conventional meteorological towers, use sound rather than radio waves for measurement. 60-100 meter met towers record data through loggers and sensors mounted on the tower while SODAR utilizes remote communications such as satellites to receive and report data. Although the SODAR system is only about 2 meters high, it can measure wind by sending sonic beams up into the atmosphere, producing audible "chirps" that listen for return "echos" or signals. By precisely measuring the time delay and frequency of the chirp's echo, SODAR can accurately measure wind speeds at heights up to 200 meters.
TÜV SÜD has Triton Sonic Wind Profilers in their inventory that you can lease and deploy to capture additional complimentary data within your project footprint.

Key Benefits of the Triton:
- Greatest Data Capture Height: The Triton can collect wind data up to 200 meters - the height of today's tallest turbines in the marketplace. The Triton has received excellent performance reviews in its ability to collect accurate data that matches with traditional met tower performance.
- Low Power Consumption: The Triton uses only 7 watts of power during constant use, increasing efficiency and lowering operational costs. It has one of the lowest power-drawing CPUs in the marketplace today. Because it operates using two solar panels, it can go unattended for long periods of time.
- Fast and Easy Deployment: The Triton can be installed and operating within a two-hour time frame.
- Industry's Leading Remote System: Many Tritons are in operation today across the world.
- Cost Effective: Due to its ease of installation and low maintenance requirements, the Triton can substantially reduce overall prices for wind data gathering.
- Near Real-Time Data Monitoring: Data monitoring is connected to a SkyServe satellite that provides ten-minute averages instantly over a secure web interface.
Equipment Micrositing and Instrumentation Orientation:
TÜV SÜD's wind energy experts provide detailed analysis of your projects footprint and available wind resources to determined placement of meteorological towers and remote sensing units. Location of data collection points such as towers and sodar equipment is extremely important to reduce uncertainty during the assessment reporting process.
Equally important, is the orientation of instruments to capture true wind data and attempt to eliminate any shadow from the tower structure or surrounding obstructions. Our meteorologists will analyze wind rose data, topography, and the project footprint to confirm specific heights and angles at which each instrument should be installed.
Data Collection and Summary Reporting:
Our wind data collection program ensures professional capturing, analysis, which is critical towards creating the foundation of your wind energy project. The loss of wind data can negatively impact your wind energy project in many ways. Your data acquisition program should involve data collected and examined on a daily or weekly basis to identify and correct failures with the communications, instrumentation, sensors, or power systems. When problems are identified, they should be corrected quickly to minimize data loss.
Wind data should be analyzed and reports generated monthly in regards to data recovery, mean monthly wind speeds and direction, and frequency distribution. TÜV SÜD's in-house meteorologists review all incoming data to ensure the integrity of your wind data acquisition program and preserve the valuable assets of your project.
