Updates on the electricity cable running through the Wirral
It has been over a year since work began on clearing the route for the high powered electricity cable which will run along the length of the Wirral Peninsular until it reaches Deeside in Flintshire. If you would like to know more about the project you can visit my previous blog HERE.
You may have seen the construction site entrances appearing on your travels and if you would like to know more about the route that the cable will be laid you can read my previous blog HERE.
The land that has been purchased for the electricity cable to run along has slowly but surely been transformed into a construction site. A temporary road runs along the area where open trenches will be dug in preparation for the electricity cable to be laid and back filled. In some areas, open trenches will be replaced with a technique called horizontal directional drilling. The areas where this technique will be utilised is under main roads, woodland areas, marsh land, Arrowe Park Golf Course and under the River Dee or where existing utilities are located. The reason why horizontal directional drilling will take place in specific areas is because it is quicker and more efficient compared to digging open cut trenches.
According to Siemens and The Prysmian Group who are carrying out the work on behalf of the National Grid and Scottish Power, the cable that will carry the electricity which is being generated on wind farms in Scotland will be buried in a trench which is approximately 1.2m deep and 750mm wide. The cable will be pulled into position by a winch then joined every one kilometre. Where the joining takes place a ‘join bay’ will be constructed so that work can be carried out 24 hours a day if necessary while special equipment is used in the right conditions to ensure the cable connects successfully.
According to Siemens and The Prysmian Group some of the 33 kilometres worth of electricity cable running through the Wirral will be laid this year but most of the cable will be laid in 2015. There are three temporary compounds which store the giant machinery that is being used throughout the process along with facilities for the construction workers. Two further compounds will be opened during the coming months as the route for the electricity cable continues to develop.
Back in 2013 the electricity cable was laid under the sea wall and came ashore at Leasowe Lighthouse. The part of the electricity cable that is buried under the sea is laid from North Ayrshire in Scotland and will be around 150 kilometres in length by the end of 2014. The total length of the cable is expected to be 400 kilometres when completed from Scotland to Wales.
Many people question why the electricity cable could not be laid through the River Dee and it is understood that the Dee Estuary is home to thousands of wader birds therefore, it is a designated Special Area of Conservation and the work for the electricity cable would have disturbed the protected wildlife.
