Buccleuch and Forsa Energy are developing NLEI in tandem with the Glenmuckloch Pumped Storage Hydro Scheme and Glenmuckloch Windfarm.
"We are confident that the proposal has balanced the views of consultees with the need to deliver a windfarm that can bring about the range of environmental and economic benefits that NLEI can deliver.
"In combination with our pumped storage and windfarm developments at the former Glenmuckloch opencast works, NLEI could put Upper Nithsdale at the heart of delivering the Scottish Government's energy strategy.
"NLEI has received support from Sanquhar Community Council and more than 100 individuals in the area.
Alan Baker, chief executive officer of Forsa Energy which is one of the companies involved in the NLEI
, said: "We're pleased to submit this updated application which we believe will address many of the concerns raised during that period and will not only reduce the visibility of turbines from several viewpoints but also decrease the footprint and infrastructure of the development.
