The power station is strategically located at the centre of five separate extraction and reinjection wells, some drilled to a depth of over 3,500m, and each reticulated back to the station. The main feature of the station is a cooling system comprising of four separate structures which when combined, stretch over 300m and are nearly 15m high.
