The company has said that it plans to redesign the 33-turbine plant because it wants to incorporate new turbine technologies that have come on stream since the scheme was first approved in 2009.
Hallett 3’s planning consent is currently under appeal before the Environment, Resources and Development Court, but AGL said it would cease legal proceedings, as the original consent would not allow for the larger turbines the company now plans to use in the proposed wind farm.
AGL has not revealed when it plans to bring forward new proposals.
Nigel Bean, head of generation development at AGL, said: "We are looking to develop a new proposal for the Hallett 3 wind farm site to incorporate the larger, more efficient wind turbines and optimise the performance of the wind farm. Timing for submission of a new planning application will depend upon our other development options."
