Wind Energy FAQ

Operational Overview

What are wind energy facilities and how do they work?

A wind facility is a collection of turbines that harness the wind to generate pollution-free energy for customers on the grid. This creates an intermittent yet predictable source of power. The average wind turbine is 90 meters tall (295 ft).

How long do wind projects operate? What happens at the end of its useful life?

We expect to operate our facilities for 30+ years. Linea Energy is committed to the responsible decommissioning of its facilities. During this process, all turbines will be removed, and the land will be restored to its initial state.

How are wind facilities operated?

Wind facilities have full-time maintenance teams. Each wind turbine will receive regular maintenance to ensure maximum availability.

Local Impact

How do wind energy facilitate benefit the community?

Wind facilities benefit local communities through the creation of local jobs, clean energy generation, increased tax revenue and consistent, long-term passive income for participating landowners.

How much land is needed?

The National Renewable Energy Laboratory, NREL, surveyed 172 large-scale wind power projects to see how much land they're really using. The direct land use is a measure of the area of such things as the concrete tower pad, power substations, and new access roads. In the United States, the direct land use for wind turbines is three-quarters of an acre per megawatt. A good size project of 200MW would have a footprint of 150 acres.

Where do we source our equipment?

Linea Energy is proud to source as much of our equipment as possible from US manufacturers. Supporting US jobs and industry is key to our success.

Can wind farms and wildlife coexist?

Yes. Wind power is far less harmful to wildlife, including birds, than traditional energy sources. Wind power is a major solution for climate change, which is the largest threat to many species and their critical habitats. To protect wildlife even further, Linea ensures its wind farms are responsibly sited, properly permitted by state and federal wildlife agencies, and thoughtfully operated.

Wind Meteorological Measuring Systems

Wind Resource Measurement Testing
  • Onsite wind resource testing is a crucial requirement for successfully developing a wind project because these measurements provide the most accurate way to collect data.
  • Strategically placed meteorological evaluation towers ("Met Towers") and remote sensing devices (i.e. LiDAR) give us a comprehensive understanding of the local wind regime.
  • The primary goal of deploying Met Towers is to reduce uncertainty and increase the precision of project area specific wind data.
  • Data is typically measured and collected for 2-3 years or longer.
  • Remote sensing devices ("RSD") are collocated with Met Towers for at least 1 year to capture all four weather seasons of data.
Met Towers
  • Onsite Met Tower data is used to assess site-specific meteorological characteristics (e.g., wind speed, wind direction, temperature, pressure, etc.).
  • Met Towers are typically constructed to a maximum height of 60m to avoid FAA airspace (>200 ft).
  • 60m met towers can be installed in less than a week when constructed by experienced field crews.
  • Equipment needed to install a Met Tower onsite: 4x4 truck, winch, gin pole.
  • Most towers are typically visited less than once a year for maintenance and general upkeep.
Remote Sensing Devices
  • Turbine hub heights are rapidly increasing, and measurements above 60m are needed to characterize the wind speed, wind direction, turbulence, and wind shear across the entire turbine rotor.
  • Remote sensing devices, such as LiDAR, can be deployed to provide actual measurements of wind speeds at and around hub height.
  • Collocated Met Tower and LIDAR measurements are used to verify wind shear, which is the wind direction and/or change in wind speed over a vertical or horizontal distance.
  • Wind shear is the "vertical gradient" or change in wind speed with height.
  • LiDAR systems can measure wind shear at heights above Met Towers by emitting lasers and then analyzing the way light bounces off of air particles to calculate how fast and by which direction the wind is blowing at different heights above the ground.
  • LiDAR units require a continuous power supply that is typically provided by trailer-based solar panel and battery system.
