Like any other substantial decision, the choice of a wind turbine is one that requires significant consideration. The selection depends on factors such as the wind resource, the goals of the project, and the price, reliability, and availability of the turbines.

The total size of the wind project depends on a number of factors such as the area of land available, the number of turbine placement sites, the number of investors in the project and the size of their contributions, the financing available, and the distribution grid’s ability to accommodate the energy. Turbine size is selected to maximize energy production efficiency and return on investment.

Wind turbine designs are based on specific wind resource and environmental standards. Four International Electrotechnical Commission (IEC) classes (I-IV) summarize these criteria. When considering wind turbine models, it is important to regard a turbine’s past track records in areas with similar wind resource and climate as the site in question. The selected turbine must fit the project and site requirements and be available for purchase within the project’s construction time frame.

To maximize cost efficiency of a wind project, it is important to not only pick the turbine well-suited to the site, but to also minimize maintenance issues. It is therefore important to select a turbine manufacturer that has a good track record in the field and a positive reputation for quality equipment. Furthermore, it is necessary that the manufacturer provides a quick response if problems do arise so that the project can remain profitable.

Most wind turbine manufacturers provide a customary 2-year warranty which covers turbine parts and labor. Some manufacturers offer an extended warranty of up to 5 years, generally at an additional cost. National Wind hires on-site Operation and Maintenance (O&M) teams in each project area, which significantly decreases costs of travel and reduces response-time to unscheduled maintenance needs.

Choosing the best wind turbine for a project requires consideration of many features and conditions. However, with the right amount of planning and analysis, wind projects can operate in an efficient and valuable way!
