The plan was to reach a maximum depth of 5 km (3.11 mi) before the end of 2016, making it by far the deepest borehole in Iceland. [12] Scientists were hoping to reach a temperature of 500 °C (930 °F), [ 13 ] [ 14 ] which would be the hottest blast of any hole in the world, breaking the former record of the IDDP-1 Krafla borehole.
The geothermal production well reached a depth of 5,275 m (17,306 ft) and the fluid injection well 2,393 m (7,851 ft). [3] [1] Between August 2020 and July 2021, the wells underwent a series of injection tests to analyse the hydrology within the fractured geothermal reservoir.

Work at the geothermal field site on the first stage of the plant (82 MW) commenced in July 2011 [7] and the plant became operational in September, 2013, one month later than scheduled. [ 2 ] [ 8 ] The power station is a binary plant, supplied under an EPC contract by Ormat . [ 9 ]
The highest concentrations are located in the Mayacamas Mountains and Imperial Valley of California, as well as in Western Nevada. The first geothermal area to be exploited for commercial electricity generation was The Geysers , a complex of 22 geothermal power stations located in Sonoma and Lake counties of California , which was commissioned ...
The Sonoma Calpine 3 power plant is one of 22 power plants at The Geysers in the United States. This is a list of operational geothermal power stations with a current installed capacity of at least 10 MW. The Geysers in California, United States is the largest geothermal power station in the world with a nameplate capacity of 1,590 MW and an annual generation of 6,516 GWh in 2018. Geothermal ...
NGDS was initially funded by the United States Department of Energy Geothermal Technologies Program (awards DE-EE0001120 and DE-EE002850), as part of the American Recovery and Reinvestment Act of 2009. The National Geothermal Data System makes use of the large collection of hard copy documents stored in state geological survey archives.
Closed-loop geothermal systems (also known as “advanced geothermal systems” or “AGS”) are a type of engineered geothermal energy system containing subsurface working fluid that is heated in a hot rock reservoir without direct contact with rock pores and fractures.: [1] [2] [3] Instead, the subsurface working fluid stays inside a closed loop of deeply buried pipes that conduct Earth’s ...
