Interested in diversification?
Landowners have an opportunity to earn additional income for each
turbine they have on their land. By diversifying into wind farms,
landowners receive a regular income, with no additional labour or
expense, over the long term.
WFD would like to hear from farmers, community groups, councils and major corporations that would like to earn additional income through generating clean sustainable energy on their land.
Does your land fit into the following constraints?
- Outside National, Regional and Coastal Parks;
- Outside Areas of Outstanding Natural Beauty (AONB);
- Outside Sites of Special Scientific Interest (SSSI).
then contact us.
What is involved?
The installation of a wind farm takes no more than typically nine to twelve months for a small to moderate scale development. The actual construction process is a series of distinct activities that can be planned in association with the landowner so as to minimise disruption to farming activities. Once the turbines are in place, normal farming can continue on around them. There is no requirement to fence off the towers and the rotating blades are well clear of the ground.
This means that less than approximately 1 acre per turbine is lost
for agricultural production, generally allowing 97% of area to be
utilised as it was previously.
The turbines are built on concrete raft or rock anchor style
foundations. The raft foundations can be up to 13.2x13.2 metres (46
feet) by 2.2 metres (6.6 feet) deep. Consequently, arable farming can
continue right up to the base of the 4 metre (13-foot) diameter towers.
The turbines are connected together by underground cables, which again
are buried below ploughing depth, approximately 1-1.5m below the
surface. Cables can usually be routed along tracks or field boundaries
to miminise disruption.
For access to the turbines, compacted tracks typically 5.5m to 10m
are formed to allow all weather access. Like the cables, we can normally
route the tracks to follow existing farm tracks or field boundaries.
Once built, the tracks must remain in place for access to carry out
maintenance or repairs and are available for farm use.
When the turbines are in operation, normal requirements for access
are limited. Unless there is a (rare) major fault, regular scheduled
maintenance will be undertaken from a small van typically every three
months or so. The turbines are monitored remotely so there is typically
no need for more frequent visits. The control systems in the turbines
are fail safe, so if a fault does occur the turbine will stop
automatically and communicate with the operating company via the
Modern wind turbines typically have a hub height of 80 metres and a blade diameter of 90 metres. When the blade passes its highest point, the tip will be at 125 metres. At the lowest point, the tips are typically 35 metres in the air. For safety and turbine performance, it is necessary to have a separation between turbines equivalent to approximately 4 to 5 blade diameters, around 360 to 450 metres or more.
A small building is sometimes provided for to store spares, consumables and some special tools. This is called an Operation & Maintenance building. The buried cables from the wind farm are collected a small substation and from there to the local transmission system.
Contractors wishing to record their interest in any existing or future WFD project may do so by contacting us. While efforts will be made to contact contractors who do register their interest correctly, if suitable work is available for tender, WFD is not obligated to do so nor does it accept any liability to do so.
