A wind farm or wind park is a group of wind turbines used to produce electricity. The facility usually has a single name and is operated by a single operator, and in many cases will have its own substation. The power delivered is the sum of the power of all wind turbines.
- To map a single wind turbine, see
generator:source=wind.
How to map
Wind farms are mapped in OpenStreetMap as power plants. A wind farm should either be mapped as an area 
or a relation 
.
Offshore wind farms
Offshore wind farms are usually mapped as areas , because they are subject to restrictions on navigation. The area can be tagged with the appropriate Seamark tags to indicate this.
Draw the outline and add:
power=plantplant:source=windplant:output:electricity=xx MWname=*operator=*start_date=*seamark:type=production_areaseamark:production_area:category=wind_farm
Onshore wind farms
Onshore wind farms are usually sited on land which is used for other purposes, without a clear perimeter fence. These are mapped in OpenStreetMap as a dispersed power plant using a relation .
Create a relation and add the wind turbines as members (no role is required).
Add the following tags:
type=sitepower=plantplant:source=windplant:output:electricity=xx MWname=*operator=*
Do not add a boundary polygon to the site relation - dispersed power plants, by definition, don't have a surveyable boundary. Renderers (such as OpenInfraMap) can calculate the boundary automatically from the location of the turbines.
