What is commercial (large) scale wind?

Large scale wind (also often called 'utility scale') refers to wind energy projects greater than 1 megawatt (MW). Typically, the electricity is sold rather than used on-site. This category can include large arrays of 100 or more turbines owned by large corporations or a single locally-owned wind turbine greater than 1 MW in size. Over time turbines have gotten larger and larger. Not so many years ago, the largest turbines were 600 kilowatt (kW) in size, and these were then the large scale models. Many wind farms still exist with turbines in the 250 kW to 950 kW size range. These are commercial scale operations, although by current (2013) standards, the turbines are now considered mid-sized. The term 'mid-size' is currently used for turbines above 100kW up to 1MW.
