Blank squares indicate areas outside the land area of the UK - i.e. areas at sea or of neighbouring countries.

Squares surrounding the central square correspond to wind speeds for surrounding grid squares.

What does this mean?

Power generated is related to windspeed by a cubic ratio. That means if you halve the windspeed, the power goes down by a factor of 8 (which is 2 x 2 x 2). A quarter of the windspeed gives you a 64th of the power (4 x 4 x 4).

As a rough guide, if your turbine is rated at producing 1KW at 12m/s then it will produce 125W at 6m/s and 15W at 3m/s.

Please Note!

Bear in mind that the NOABL windspeed dataset used here is a model of windspeeds across the country, assuming completely flat terrain. It isn't a database of measured windspeeds. Other factors such as hills, houses, trees and other obstructions in your vicinity need to be considered as well as they can have a significant effect.

If you're thinking about installing a wind turbine, you should perform your own windspeed measurements using an anemometer to determine what the actual figures are.

Find your average windspeed by postcode or OS grid ref (beta version)

(quick and dirty results)

Note: You can achieve better accuracy if you convert a postcode to its OS Grid Reference using Streetmap.co.uk and enter the relevant OS X and OS Y coordinates instead. We strongly recommend that you do this.

OS Grid Reference ( , ) , (accurate results)

Note that these should be the full easting (X) and northing (Y) values in metres and NOT include the OS grid letters (unlike the NOABL tool on the DTi and BWEA's websites). eg Nelson's Column in Trafalgar Square in London is at 530025E 180379N, so enter 530025 for X and 180379 for Y.

England/Wales/Scotland Northern Ireland (not yet available)

Note:

This is a beta version, please be patient, and let us know if you find any odd problems.
