FIVE wind turbines, each more than 400ft high, could be built on the Mersey river wall, producing enough power to meet the household needs of towns the size of Crosby or Wallasey.
The turbines will join the existing six wind-power generators already erected along the river wall on the Liverpool-Sefton boundary.
The Mersey Docks and Harbour Company has submitted planning applications for the £12m development to both Sefton and Liverpool councils.
Three of the proposed turbines will be in Sefton and the other two in Liverpool.
If the go-ahead is given it is anticipated that the turbines will be built next summer.
Each of the new generation windmills will be able to produce up to three megawatts of electricity, five times the power each of the first six turbines positioned on Seaforth Dock wall is capable of generating.
The turbines will be spaced some 500 metres apart over a two kilometre stretch of the river front from West Alexandra Dock, just south of Gladstone River Entrance, to the southern end of Huskisson Dock.
Their location further up river and straddling the boundary between Sefton Borough and the city, means that to catch the wind, their tapering towers will be 90 metres tall, against the 50 metre towers of the turbines at the mouth of the Mersey.
Each of the blades will be slimmer but longer at 45 metres, making a maximum total height of 135 metres.
The decision to build a second generation of wind turbines was prompted by the push for electricity produced from renewable sources. Much of the power from the new turbines is expected to be sold to a supplier serving local communities.
