If approved by Cornwall Council, the proposed project would have a capacity of 25.3MW, while Good Energy would offer customers within 5km a 20 per cent discount on their standard regional tariff.
The company will also provide a local community fund worth £63,250 a year, rising in line with inflation, for the lifetime of the project.
Juliet Davenport, chief executive and founder of Good Energy, said: “We believe The Big Field windfarm can provide a lasting positive legacy for the environment and the local community, and we are proud to put our name to it.
“Having consulted locally for over a year, we believe this project meets all planning requirements and supports both local and national renewables targets.”
