A binary cycle is a method for generating electrical power from geothermal resources and employs two separate fluid cycles, hence binary cycle. The primary cycle extracts the geothermal energy from the reservoir , and secondary cycle converts the heat into work to drive the generator and generate electricity .
Geothermal power is highly scalable: a small power station can supply a rural village, though initial capital costs can be high. [54] The most developed geothermal field is the Geysers in California. In 2008, this field supported 15 stations, all owned by Calpine, with a total generating capacity of 725 MW. [55]
Geothermal resources are theoretically more than adequate to supply humanity's energy needs. Most extraction occurs in areas near tectonic plate boundaries. The cost of generating geothermal power decreased by 25% during the 1980s and 1990s. [1] Technological advances continued to reduce costs and thereby expand the amount of viable resources.
Geothermal power stations in the United States are located exclusively within the Western United States where geothermal energy potential is highest. The highest concentrations are located in the Mayacamas Mountains and Imperial Valley of California , as well as in Western Nevada .
The Te Huka Geothermal Power Station, also known as Tauhara One, is a 23 MW binary cycle geothermal power station situated near TaupÅ, New Zealand. The power station is operated by Contact Energy . In July 2008, Contact Energy announced that the contract for supply and construction of the binary cycle equipment was awarded to Ormat Technologies .
The geothermal field would then be acquired by Aboitiz Power in 2009. [3] [4] The company would own and operate the plant under its subsidiary AP Renewables. [5] In January 2023, a new binary cycle power plant within the Tiwi Geothermal Power Plant broke ground. It will add 17-MW capacity to the existing geothermal complex. [6]
The levelized cost of electricity (LCOE) is a metric that attempts to compare the costs of different methods of electricity generation consistently. Though LCOE is often presented as the minimum constant price at which electricity must be sold to break even over the lifetime of the project, such a cost analysis requires assumptions about the value of various non-financial costs (environmental ...
A binary cycle power plant was constructed in 2005 to use lower-temperature steam that had already gone through the main plant. [2] [3] This increased the total capacity of the power station to 181 MW. [1] The Wairakei power station is due to be phased out in 2026, replaced by the Te Mihi geothermal power station. [4]
