North Iceland Geothermal Area Tested

Landsvirkjun, the national power company, is currently conducting a stress test of the high temperature geothermal area Theistareykir in northeast Iceland. For the first time four boreholes are blowing up steam at the same time.

The four holes will blow for a few months so that information can be obtained on how the geothermal tank reacts. The results of the testing will later be placed in simulators and the final results of the test are expected by the middle of next year, Morgunbladid reports.

The company Theistareykir ehf. has drilled six test holes in the area. Project leader Bjarni Pálsson said all of the holes are hot but the productivity varies. He states that the entire area is likely to produce at least 90-100 MW of electricity.

Continued drilling at Theistareykir will be determined by a joint environmental impact assessment of planned power plants and an aluminum smelter, along with energy sale. The evaluation of the area is being reviewed by the Icelandic National Planning Agency.
