Research into on farm power generation has produced details of the options, and explored feasibility of adoption of such systems. Growers can use this to help them make informed decisions about the economic, technical and operational costs and benefits of the various technologies, the challenges of installation and operation, and the suitability of systems to individual ventures. This analysis focused on 50–500 kW capacity second hand wind turbines. Despite uncertainty about the total capital required to install a second hand wind turbine, it appears that they will be viable in many cases because they cost significantly less than new plant. Wind is viable if the cost of electricity is more than about 10c/kWh and most of the electricity generated can be used on site.
