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. In addition, in July 2021, full reservoir testing (simultaneous ...
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.
NM4 was the first well in New Zealand to encounter a pluton, at a depth of almost 2400m. Mighty River Power undertook further drilling in 2008-09, with wells NM5, NM6, and NM7 drilled to depths of 2997m, 3398m, 2963m respectively. [5] Resource consents for further development were granted in May 2010. [6]
In total, electrical station construction and well drilling costs about 2–5 million € per MW of electrical capacity, while the levelised energy cost is 0.04–0.10 € per kW·h. [10] Enhanced geothermal systems tend to be on the high side of these ranges, with capital costs above $4 million per MW and levelized costs above $0.054 per kW·h ...
Energy Plant 5 was built in 1999 to substitute the old energy plant 1 and to increase the power and hot water, so the demand could be met. It produces with its 30 MW turbines and 75 MW thermal energy exchange system, around 225 GWh per annum. Energy Plant 6 is a condenser plant with unique high pressure steam turbines and a total capacity of 30 ...
3) per year, [5] of a reserve of 3.4 million tonnes. [ 6 ] In 2016, the Australian firm Controlled Thermal Resources (CTR) announced plans to build a 140 MW geothermal power plant and a lithium extraction facility capable of producing 15,000 tons (13,600 tonnes) by 2023 and 75,000 tons (68,000 tonnes) by 2027.
As of 2007 plant construction and well drilling cost about €2–5 million per MW of electrical capacity, while the break-even price was 0.04–0.10 € per kW·h. [10] Enhanced geothermal systems tend to be on the high side of these ranges, with capital costs above $4 million per MW and break-even above $0.054 per kW·h.
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 ...
