Liz Truss has lodged a formal objection to a proposal for 87 miles of electricity lines stretching from West Norfolk to Lincolnshire.
The South West Norfolk MP has objected to the National Grid infrastructure plans, which would see overhead lines on pylons run from Grimsby to the Walpole sub station as part of infrastructure to provide energy.
As part of the 'Great Grid Upgrade', two converter stations and one substation are proposed for the Walpole area.
Earlier this year, villagers in the West Walton and Walpole areas mounted a campaign against the scheme, arguing that the 50m-high pylons will have a “massive impact on the landscape, environment, natural habitats, tourism and agriculture”.
Now, Ms Truss has said: "All this infrastructure would not only be a physical blight on the beautiful local landscape, but it would put at risk high-quality farmland, impacting the livelihoods of Norfolk farmers.
"This would all have a major detrimental impact on West Walton, its residents and the surrounding area.
"The entire so-called ‘Great Grid Upgrade’ is being undertaken as a result of misguided and hastily agreed net zero policies which do not deliver value for taxpayers’ money.
“The Government should be revisiting its net zero policies rather than pressing ahead with ill-conceived schemes such as this."
Ms Truss is encouraging concerned constituents to join her in lodging their objections to a consultation on the scheme, which closes on June 17.
National Grid unveiled its early-stage proposals at the start of this year, describing it as a key infrastructure project in the UK’s transition to a decarbonised energy system.
At the time, project director Ben Muncey said: “This reinforcement between Grimsby and Walpole is essential in the UK’s journey to net zero by 2050 and is part of a wider programme to upgrade the entire network.”
Grimsby to Walpole would be able to transport six gigawatts of power and connect proposed new sources of electricity that are planned to come onshore on the east coast.
The project involves proposals to build a new 400,000 volt overhead electricity transmission line and five new substations – including one at Walpole.
It would run between two new substations in Grimsby and Walpole, with three new connection substations along the route.
