In the beginning 1976, the Svartsengi Geothermal Power Plant was completely liquid-dominated, but it changed into a liquid dominated with a steam cap geothermal system.[7]
Today, it consists of 13 production boreholes connected to the six plants, eight of those wells are producing a mixture of steam and brine and the other five are shallow dry steam wells.
It also possesses one of the largest Supervisory control and data acquisition (SCADA) in Iceland with the P-CIM monitors and the 50 substations, which include hot water/ cold water/ electricity distribution systems and 11 turbines and generators
