1978, though the power plant did not work to its full potential until the seismic and volcanic activities strongly declined in 1984 and further boreholes were drilled. In 1996 even more boreholes were drilled and a second turbine was installed, but Krafla was only able to operate at 60 megawatts in 1999, after the renovations were finished, which mainly consisted of renewing the steam gathering system in order to meet the standards for the double pressure inlet to the turbines and the control and safety system in general.

The Krafla geothermal power plant consists of two 30-megawatt units, with double pressure inlet and dual-flow turbines with 5 steps on each side. It takes its energy from 17 high-pressure production wells with 110 kg/second of 7.7 bar and, due to new technologies, 5 low-pressure production wells

and volcanic activities in the area threatened the building of the power station, like the major volcanic eruptions less than 2 km from the power station away, introducing the possibility that it would never start operating at all. Nevertheless, it was finished in early 1977 and was launched in

One of the additional wells (IDDP-1), which was drilled in the Krafla geothermal reservoir in 1999, is known for being the world's hottest geothermal well, since its borehole reaches magma at its lowest point, with a temperature of 430 °C. The right to use the well is owned by
Mannvit.

The construction work started in 1974, but due to volcanic activities in the area, building was slowed. The Krafla power station was officially launched in the early 1977, but was only able to produce at its full 60-megawatt capacity after a second

The other seven wells are not in use. The turbines consume 52.5 and 17.8 kg/s of high- and low-pressure steam each. If the inlet pressure and the mass flow were raised, the output of each turbine could be increased to 35 megawatts.

The two companies which were in charge of the engineering of the Krafla geothermal power station since very early in its developing process were
Mannvit and Verkís.

The construction work of the Krafla geothermal power plant started in 1974, with trial boreholes, after a contract over two planned units was signed.
