flash steam for heat and electricity generation. The pilotplant studies were the basis for the design of the firststages in constructing the plant Nevertheless a lot ofdetails. materials and components had to be tested beforethe main plant was designed and constructed. All the samethe power plant has been able to supply thermal energy tothe different communities according to the requirement atany time since the commencement of the programme.2.9 History of developmentThe highlights of the historical development of t he projectare as follows (Bjornsson. 1983):1971 - 1972 Wells SG-2 and SG - 3 were drilled to depths of 240and 400 m respectively. The results turned out to be veryencouraging proving there was a high temperature fieldwith a brine temperature of 235°C.1974 The Orkustofnun (NEA) built aSvartsengi. Two wells weredrilled. SG-4pilot plant at(1700 m) and SO-5(1525 m).1974-1975 Tests were carried out by the Orkustofnun (NEA)in the pilot plant which later became the basis for thedesign of power plant 1.1976 Preliminary power plant of 3 MWt was commissioned onNovember 6.1977 First unit of power plant 1 of 8 MWt was commissionedin November.1978 First 1 MWe turbogenerator was commissioned in April.Second unit of power plant 1 of 12.5 MWt was c ommissionedin November. Well SG-6 was drilled to a depth of 1734 m.1979 Third and fourth units of power plant of 2 X 12.5MWt were commissioned. The second 1 MWe turbogenerator was
25commissioned. Well SG - 7 was drilled to a depth of 1438 m.1980 Third 6 MWe t urbogenerator was commissioned. WellsSG - 8, SG-9, SG-l0, and SC - 1t were drilled to depths of1603, 994, 425 and 1'41 m respectively.1981 First unit of power plant 2 of 25 MWt was commisionedin May. Second and third units of power plant 2 of 2 X 25MWt were commissioned 1n September.1982 The tota l installed capacity in power plants 1 , 2 and3 became about 46 MWt • 2 MWe, 75 MWt and 6 MWerespectively. The last well to date, namely SG-12 wasdrilled to a depth of 1488 m. Relnjection was done for 25days in the months of September and October.
