The pylons marching across Wales
The news site says that Dr Jonathan Dean, a trustee of the countryside charity CPRW, has written a lengthy submission to the Independent Advisory Group on Future Electricity Grid for Wales in which he argues that a new transmission grid from north to south Wales is wholly unnecessary:
He states: “In our experience, the main issue the public have with overhead electricity lines is pylons. The public just don’t like them. The bigger they are, the more they dislike them.
“The subject has been extensively studied in the academic literature. There are even books on the topic, and a study into the Hinckley C connection by Matthew Cotton and Patrick Devine-Wright in the Journal of Environmental Planning and Management reached the following interesting conclusions:
* The findings show how potential health effects from electric and magnetic fields (EMF) and visual impacts are perceived to industrialise rural places,disrupt place attachments and provoke local opposition.
* The findings challenge the ‘not-in-my- back-yard’ assumption that citizens are selfish place-protectionists that lack the technical sophistication necessary to take a strategic viewpoint on transmission system development.
* They also reveal how decision making under the … Planning Inspectorate … presents a challenge to procedural justice, as front-loaded developer-led consultation practices curtail citizen input to key decisions on alternative technologies (for example, underground or undersea lines). This is likely to exacerbate public mistrust of transmission system operators and provoke further organised protest.
“So in brief, people don’t like them due to health worries and visual amenity loss, it’s wrong to brand them NIMBYs and things won’t change unless the planning process does.”
Dr Dean points out that there is a presumption in favour of pylons as the default technology, but that offshore wind, and any associated infrastructure is deemed a Critical National Priority, with the highest level of support in the planning system.
He states: “The stage seems set for more public opposition as the plans for progressing to net zero, in the long term, and clean power, in the short term, get revealed.”
Pylons are used by both the transmission grids and distribution grids. For pylons carrying a voltage higher than 132 kV, the development of overhead lines is consented via the Planning Act 2008, with applications examined by the Planning Inspectorate and decided by the Secretary of State for Energy Security and Net Zero, Ed Miliband.
132 kV is the highest distribution voltage and consented the same as transmission, except for the cases of lines serving Welsh generators that are totally in Wales, in which case they are examined by the Welsh Government’s planning body PEDW and decided by Welsh Ministers.
Dr Dean states that lines of under 132 kV are typically on wooden poles or double poles, and are far less controversial with the public. It is the 132 kV and 400 kV lines that cause the majority of issues, and most of these are consented by the Secretary of State.
He continues: “Wales has committed to be globally responsible by hosting enough renewables to at least meet its own electricity needs by 2035.
“It is entirely feasible for Wales to generate the equivalent of 100% of its electricity demand by 2035 using only offshore wind power. This would have a dramatic impact on the requirements of the transmission and distribution grids.
“It is our opinion that the reason this is not happening is because the Welsh Government has failed to secure sufficient development leases from the Crown Estate, either under the previous UK government or the current one. This may be due to the constant confusion between a need for more offshore capacity and the desire for the Crown Estate to be devolved.
“It would be entirely possible for Wales to have far more offshore wind power irrespective of the status of the Crown Estate. While CPRW does support devolution of the Crown Estate in Wales, this should not be seen, or used, as a means of delaying the building of more offshore wind capacity, particularly in the Irish Sea which is shallow and able to be developed using conventional fixed base turbines (like the North Sea).”
There appears to be two issues here. Firstly, the need to concentrate more on off-shore wind, but secondly if the Crown Estates was devolved to the Welsh Government, it would make it much easier for them to advance that agenda.
In the meantime, there needs to be a clear policy to underground cables rather than rely on pylons to better protect our landscapes.
