Ecotricity will erect 22 windmills with a collective generating capacity of 66MW, or enough to power 40,000 homes each year, it says.
The controversial project has spent three years in the planning process. Ecotricity submitted its planning application to the secretary of state back in December 2009.
Ecotricity founder Dale Vince said: “Heckington Fen is a superb location for a wind park, probably the best we've ever seen.”
He added: “We’re grateful to the secretary of state for his decision in the face of considerable political hot air right now on the subject of windmills, and we’d also like to thank the many people in the local community that wrote letters of support for the project.”
A DECC spokesman said: “Onshore wind has an important role to play as part of a balanced energy mix. This development will enhance our energy security and help to reduce greenhouse gas emissions.”
