wind farms in uk, page-11

You obviously know about the 'Mail' mjshackl. Thanks for backing me up on that one.

Hotcopperinvest, wind farm developers monitor wind speeds and frequency for at least a year on site prior to installing wind turbines. Often the wind monitoring equipment is up for 2-3 years before the wind turbines are installed. Hence, it is known what the the likely return is going to be prior to them being installed. Here in Scotland where I am based the capacity factor of wind farm is typically 30-35%. Capacity factor should not be confused the percentage of time that wind farms generate power, which is typically 75-85% of the time.
