Question to the Department for Energy Security & Net Zero:

To ask His Majesty's Government what is the average environmental cost of producing and installing a power pylon within the range of 36 to 190 metres in height, including a breakdown of the costs of the materials for the bases required to support these pylons.

The Government does not hold data on the average monetary or environmental cost of producing and installing an electricity pylon. Such assessments are undertaken by the relevant planning applicant and considered as part of the decision-making process by the Secretary of State. A wide range of context specific, qualitative and quantitative factors determine said value.

The environmental impact of proposed pylon developments is assessed on a scheme-by-scheme basis with the method, content and scope of assessment dependent on the likely significance of the proposed scheme’s environmental impact based on its size, nature, location and the relevant legislative and policy frameworks.
