“USE OF NEW BRIDGE
A tunnel under the Menai Strait is welcome. However plans for a third road crossing of the strait have progressed. The option to save costs by using the new bridge must be kept open.
ECONOMIC IMPACT (ON TOURISM)
Beaumaris Town Council must consider the well being of the town which depends on tourism. Tourism is important for Anglesey and its importance will grow. Anglesey has a quiet and undeveloped character. This contributes to a sense of ‘getting away from it all’. The tourist industry is not just restricted to the coast. A double line of pylons on the doorstep of an inland holiday cottage will erode the sense of ‘getting away from it all’.
Support of one industry (power generation) must not be at the expense of another (tourism).
UNDERGROUND CABLING
Placing the new line close to the old line will reduce the area visually effected. However a double line has an intense impact on particular locations. Placing the new line underground better protects the visual landscape.
Underground cables are more expensive but National Grid have not placed enough weight on the economic impact of a visible pylon line. A small negative impact on the £250 million per year tourism industry of Anglesey runs to many tens of millions of pounds over the lifetime of the new power station.
National Grid have been willing to put other connectors underground.
National Grid’s assertions about the cost of underground cables will be challenged. An independent report noted that the National Grid’s estimated costs are greater than those incurred by other distributors. Transmission operators in Europe have found that the investment cost ratio is 2-5 to 1 rather than the 10-20 to 1 quoted by National Grid. Underground cables are more reliable, National Grid have ignored this long term economic benefit.
PYLON DESIGN
The use of a few low profile pylons is welcome. A low profile design should be used throughout.
A double line of dissimilar pylons will be no more intrusive than a double line of similar pylons. A low profile design will reduce the visual impact of the new line.
The recently approved ‘T’ design would be ideal. Alternatively a low profile lattice design could be used.
UNDERSEA OPTION
The Town Council believe that a sub-sea cable is the best option. The Western Link project provides a 385km link through the Irish Sea. An offshore link along the North Wales coast would be around a third of the length and therefore cheaper. Sub-sea links elsewhere appear to be even cheaper than the Western Link.
National Grid’s assertion that sub-sea would cost ‘many hundreds of millions of pounds more’ will be challenged.
A sub-sea connection would be no less resilient than an on-land option. The existing pylon line will provide back-up transmission capacity should the sub-sea cable fail. The decision to route the new pylon line close to the existing line means that they are both vulnerable to a single incident.
