National Grid has outlined new proposals to upgrade electricity transmission infrastructure in Lincolnshire and neighbouring regions. The aim is to support growing energy demands and facilitate the transition to renewable power sources.
The latest proposal involves a 37-mile overhead power line connecting a planned substation at Weston Marsh near Spalding to a grid connection point in eastern Leicestershire. The project is in early development, and some routes would use existing transmission corridors.
This follows an earlier controversial proposal for a separate 87-mile pylon route between Grimsby and Walpole, which has met resistance from local authorities, including Lincolnshire County Council.
In parallel, National Grid is advancing its Eastern Greenlink project series (EGL3, EGL4, and EGL5), designed to bring offshore wind-generated electricity from Scotland to England. These primarily undersea cables would land at Anderby Creek near Skegness, with underground connections extending inland.
EGL5 is planned to terminate at a new converter station near Alford, with two potential sites under consideration: Bilsby or Huttoft. Previous plans for converter and switching stations in Bilsby and a separate underground line have been scrapped.
Each Greenlink cable is expected to transmit enough power to supply approximately two million homes, reflecting a strategic shift from imported fossil fuels to domestic renewable energy.
Public consultations for EGL3–5 are underway, with meetings scheduled this month, and separate consultations for the Weston Marsh pylon line set for June.
