Hellisheidi geothermal power plant is a flash steam, combined heat and
power plant (CHP) located in SW-Iceland, on one of the largest wet
geothermal systems (high-enthalpy) in Iceland. The plant’s purpose is
to meet increasing demand for electricity and hot water for space
heating. Development plans call for incremental or phased expansion
from 2006 to 2010 to an estimated maximum output of 300 MWe and 400
MWth, making it the largest geothermal combined heat and power plant in
Iceland. The plant owner is Reykjavik Energy.

Nesjavellir Geothermal Power Plant field is a high-enthalpy geothermal system within
the Hengill area of SW-Iceland. Construction of the geothermal power
plant began in 1987 and the first stage of the thermal plant was
commissioned in 1990, following an intensive drilling and testing phase
in the 1980s. The last 30 MWe turbine generator unit was commissioned in
2005.

Vatnsfell Hydroelectric Power Station was constructed in 1999 - 2001. It
utilizes the head in the diversion canal between Lake Thorisvatn and
the Sigalda Station reservoir, located in southern Iceland. There is one
main dam, the Vatnsfell Dam, and two small saddle dams. |

Burfell Hydroelectric Power Station is located near the head of the
Thorsardalur Valley in South Iceland. It was constructed over a
three-year period from 1969 – 72. All of the station’s six turbines were
upgraded in 1997-98, which boosted installed power from 210 MW to 270
MW. Trash racks and intake gate equipment were renovated during the
years 1996-03. |

Sigalda Hydroelectric Power struction of the Sigalda Hydroelectric Power Station began in 1973, and
the station’s three 50-MW turbines went online in 1977-78. The Sigalda
Station is linked into the national grid with 220 kV transmission lines
to the Sultartangi, Hrauneyjafoss and Vatnsfell Stations, as well as a
132-kV line to southeast Iceland. |

An International Centre of Research and Applied Technology for Alkali
Aggregate Reactions (AAR) has been established at the laboratory of
Mannvit Engineering, in Iceland. The founder of the Centre, Prof. Børge
Johannes Wigum, has for the past two decades carried out research and
consulting regarding AAR. The laboratory employs a staff of
highly-skilled experts in the fields of concrete, aggregate, geological
and geotechnical engineering.
