The National Grid has abandoned plans to roll out new designs for its electricity pylons because of their high cost and noise complaints from nearby residents, The Telegraph has reported.

The T-pylon design was first unveiled in 2015 as the future design for Britain’s electricity grid. But since then, the new designs have only been installed in one location in Somerset as part of the new 35-mile Hinkley Point C to Avonmouth connection.

Each of the T-pylons built so far support 12 conductors for a total of 460km of new power lines across the whole route. Their design sees six conductor spans attached to each diamond earring-shaped insulator on either side of the structure, with wires installed in sections of up to a dozen T-pylons at a time.

But the £17m redesign did not feature as part of the government’s efforts to expand the capacity of the grid, which is necessary to bring more low-carbon energy into the system.

They were apparently subject to a host of problems, with residents complaining...

  • Since the Telegraph T-Pylon article was written the following additional information has been published in other news sources:-

    1- The extra steel and larger foundations required for the T-Pylon structure costs an additional 330,000 pounds per pylon.

    2- In response to reports from a small number of landowners about noise levels in windy conditions we have installed an updated specification of spacer on some sections of the overhead electricity line-- January 7, 2025 local "Burnham-on-the sea" newspaper . 

    3- Localized flooding around their bases have been observed due to their large foundations.

    4- Un-named T-Pylon architect slams National Grid for being "Stuck in the past"- January 6, 2025 Headline. 

    5- Danish design firm Bystrup's attempts to reduce costs by shortening T-Pylon by 8 metres was not completely successful.
