National Grid's Anglesey energy and pylons plan prompts meeting 24 January 2014 Last updated at 07:06 By Iolo ap Dafydd BBC Wales environment correspondent A public meeting is to call on the National Grid to change its preferred option of building pylons across Anglesey to improve north Wales' electricity connection. Officials have been in talks for a over year about linking wind farms and the island's planned new nuclear power plant to the grid. Residents prefer an option of an under-sea cable carrying power to Deeside. Concerns will be raised with MPs at the meeting at Llanfairpwll on Friday. The plans focus on taking power generated on and around the island and connecting it into the electricity network over the next 10 to 15 years. The meeting is being held as there is growing opposition against building new power lines on pylons across the island as part of improving north Wales' electricity connectivity. Sensitive area We are becoming an energy superhighway and we expect a relative cost to compensate for the energy we are carrying End Quote Hanna Huws Llanfairpwll community councillor Residents say a cable under the sea would avoid using 25 miles (40km) of pylons across Anglesey and an official area of outstanding natural beauty at Menai Strait. However, the National Grid's preferred option would be three times cheaper at £750m. It has been a year since the National Grid consulted on five different options on how to bring power for electricity from Anglesey to the rest of the grid and the UK. Locals on both sides of the Menai Strait say they are concerned that this environmentally sensitive area may see a new line of pylons and power lines crossing the narrow stretch of sea. Grid engineers and planners have to plan for a 3.6 gigawatt of power from the planned Wylfa Newydd nuclear plant, as well as large wind farms out to sea which could produce another 2 gigawatt of power for the UK in 10 to 15 years' time. That is equivalent to a tenth of Britain's peak electricity demand in winter. Friday's public meeting is in Llanfairpwll where an existing line of pylons carries power by the village over the Menai Strait to a sub station at Pentir near Bangor. The meeting has been called by Hywel Williams, the Arfon MP, who wants a less intrusive route carrying electricity out of the area. Montgomeryshire MP Glyn Davies and Anglesey's Albert Owen will also be at the meeting. It seems there is cross party support for a sub-sea connection rather than more overhead power lines. Llanfairpwll resident and community councillor Hanna Huws said with 10% of the UK's energy "traversing the area," the under-sea cable option should not be discounted on cost. "We are becoming an energy superhighway and we expect a relative cost to compensate for the energy we are carrying," she said. Wales National Grid external affairs manager Chris Isaac said: "When we consulted on the overhead line option we heard loud and clear from people that they thought the Menai Strait was a really sensitive area. Now we are doing studies there to look at ways we could potentially cross the Menai without using an overhead line.
