Since the completion of Crystal Rig 2 in 2010, Siemens have based their main service centre for all wind farms in the South East with Siemens turbines in use at the turbine control centre at Crystal Rig whose offices are shared with Natural Power.

The farm was built in several stages: Crystal Rig: Completed in May 2004 it consists of 20 Nordex N80 turbines producing a maximum of 50 MW.

Crystal Rig 2 & 2a: Both completed in September 2010[1] they consist of 60 Siemens SWT-2.3 turbines in total capable of producing 138 MW.

[2] Crystal Rig IV: A planned extension of an additional 11 turbines which will bring the wind farm's capacity total up to 262.5 MW.

[3] Crystal Rig 1 and 1a are connected to the Scottish Power Transmission network at the Dunbar substation 10 km to the north.
