National Grid has released new information on its proposal to build two major substations on farmland near Spalding, as part of the wider Grimsby to Walpole electricity upgrade. The Weston Marsh A and B sites form a key element of the 140km reinforcement project designed to increase grid capacity in eastern England.
The substations would be positioned near Weston Marsh and linked by a short underground cable. They would also connect directly into the planned Grimsby to Walpole pylon route and to the incoming electricity cable from the Outer Dowsing Offshore Windfarm. Each substation is expected to span an area comparable to 10 football pitches and reach up to 15 metres in height.
If approved, these facilities would help meet rising electricity demand in Lincolnshire, where usage is forecast to double by 2050. National Grid has noted that the existing network is already under pressure. The Weston Marsh sites are two of six large substations currently proposed across the county as part of national grid reinforcement work.
Details of the plans are available through National Grid’s website as part of a new public consultation. In-person events are scheduled for 28 November at Weston Village Hall and for 29 November at Moulton Seas End Village Hall. An online webinar will take place on 3 December.
