Wind Power in Stand-Alone Systems
Wind Power can be used in off-grid systems, also called stand-alone systems, not connected to an electric distribution system or grid. In these applications, small wind electric systems can be used in combination with other components—including a small solar electric system—to create hybrid power systems. Hybrid power systems can provide reliable off-grid power for homes, farms, or even entire communities (a co-housing project, for example) that are far from the nearest utility lines.
An off-grid, hybrid electric system may be practical for you if the items below describe your situation:
-
You live in an area with average annual wind speed of at least 9 miles per hour (4.0 m/s).
-
A grid connection is not available or can only be made through an expensive extension. The cost of running a power line to a remote site to connect with the utility grid can be prohibitive, ranging from $15,000 to more than $50,000 per mile, depending on terrain.
-
You would like to gain energy independence from the utility.
-
You would like to generate clean power.
