The towers often exceed feet, which need to be fitted with obstruction lighting. Projects of this size warrant community involvement and endorsement or approval at all levels. This class, except in very unusual situations, is typically financed through commercial lenders with their own due-diligence requirements and therefore require feasibility studies and onsite resource assessment campaigns. Utility-scale wind turbines , while also occasionally installed at the point of use, are generally installed in large groups producing energy for sale.
These are highly efficient, state-of-the-art wind turbines that operate with exceptionally high availability rates and generate cost-competitive electricity at power plant scales. These large turbines have rotors measuring more than feet in diameter and are installed on tall towers that require aviation obstruction notification and lighting. Because of their size and the scale of the installations, utility-scale wind turbines require environmental, utility, and public coordination at the highest levels.
Utility-scale wind farms require exacting resource assessments, legal and financial due diligence, utility integration, and financing typical of very large capital investments installations, such as airports. What Is Wind Power? Wind Power Animation This aerial view of a wind turbine plant shows how a group of wind turbines can make electricity for the utility grid.

When the wind blows, a pocket of low-pressure air forms on the downwind side of the blade. The low-pressure air pocket then pulls the blade toward it, causing the rotor to turn.
This is called lift. The force of the lift is actually much stronger than the wind's force against the front side of the blade, which is called drag. The combination of lift and drag causes the rotor to spin like a propeller, and the turning shaft spins a generator to make electricity. Photo from University of Maine. Wind turbines can be used as stand-alone applications, or they can be connected to a utility power grid or even combined with a photovoltaic solar cell system.
