Green Rigg Wind Farm is a Wind Prospect proposal for eighteen 2MW wind turbines within the Birtley Parish of Tynedale. A formal Planning Application was submitted to Tynedale District Council in January 2006. It included a full Environmental Impact Assessment (EIA). During the course of the development process, both before and after submission of the planning application, the wind farm design evolved to reflect the outcome of a series of site investigations, consultations and consultee responses. By July 2006 Wind Prospect had completed the submission of Supplementary Environmental Information to Tynedale District Council.

Wind Prospect Senior Development Manager for the North East, Tim Matthews, said:

"A series of iterative environmental impact assessments and consultations were an important part of the design process. Reviewing each environmental aspect as new information came to light enabled us to factor all relevant considerations into the design of the development. By this means we have been able to minimize the potential impact on any one of the aspects, and come up with a design for a wind farm which will both fit in with the landscape and environmental character of the area, whilst at the same time making a significant contribution toward our need to both improve our energy security and reduce our reliance on fossil based fuel technologies."
