Careers in Wind Farm Development: Wind Energy Analyst

Sarah Lozanova | Monday November 30th, 2009 | 3 Comments

This is the third article in a seven part series on careers in wind farm development. The first, second, and third parts can be viewed here.

Desired information is frequently extrapolated from a data set, often with help from software including Windagrapher, WindFarmer, WindPRO, or Excel. This information then provides vital information for determining the financial viability of a potential wind farm.

“Towers over 60 meters in height require a special permit from the Federal Aviation Administration, so wind energy is normally assessed between 50 and 60 meters,” says Diane Reinebach, Senior Energy Specialist for RMT, Inc. “That data is then extrapolated up to 80 meters, which is the hub height of a wind turbine.”

Turbines are designed for different wind conditions, so careful selection is important to maximize the energy output of a wind farm. The layout of a project must account for numerous factors to optimize productivity, minimize construction costs, shorten the lag time of a project, and adhere to environmental restrictions.

“We develop a layout for wind farms based on many variables including characteristics of the turbine, the height, the blade and site conditions,” says Reinebach. “We do that as a team effort. It isn’t just a meteorological study. The idea is to maximize energy production based on construction costs, and various setbacks for occupied residences, roads, non-participating landowners, and environmentally sensitive areas.”

Setbacks vary by location and require a specified minimum distance between a given landmark and a wind turbine. Some software can take such considerations into account when preparing turbine layout.

A job in the energy assessment field draws on a variety of skills, according to Reinebach. She finds her background in mechanical engineering helpful for understanding turbine output and wind loads that affect structural integrity of a turbine. Her 15 years of experience working with an electric utility boosts her understanding of customer needs. Computer skills, a meteorological background, an ability to work with a large data set, and an understanding of fluid dynamics, are all beneficial.

    wind energy is a great way to be green but we need more local tech schools to see this fact

    Yes, the educational system will need to help train for these careers. There are a handful of community college programs, but most of them are in wind farm maintenance, not development.

    I drive over the road, mostly in Texas and see many of the components being transported. Why are we not utilizing rail when transporting component parts? We say we are saving energy, but we are using a huge amount of fuel transporting component parts. I realize that a some of the tower sections are too large to ship by rail, but we should look at the alternatives. A train of blades, top tower sections, and generator components shipped to a central location to the farm site would use much less fuel. Isn’t that what this is all about, using one resource to replace another. How much fuel are we consuming before we generate a watt?
