Construction of a first reference plant, the Yaomeng power plant in China, commenced in 2001. On 3 June 2014, the Australian government's research organization CSIRO announced that they had generated 'supercritical steam' at a pressure of 23.5 MPa (3,410 psi) and 570 °C (1,060 °F) in what it claims is a world record for solar thermal energy.

The power station consists of two 1,000MW ultra-supercritical coal-fired units, each with a once-through boiler and a 3000rpm steam turbine operating at 603°C and 270 bar. The units feature water-cooled stator, hydrogen-cooled rotor generators, a 160m-high chimney with 9.1m internal diameter, and on-site ash storage facilities.
Also to improve power generation efficiency, Unit 2 adopted Tohoku Electric's first ultra-supercritical boiler and steam turbine with a main steam temperature of 566 °C, a reheat steam temperature of 593 °C, and a main steam pressure of 24.1 MPa.
Named for former SWEPCO president and CEO John W. Turk Jr., the plant came online in 2012 as the first sustained "ultra"-supercritical coal plant in the United States, reaching boiler temperatures above 1,112 °F (600 °C) and pressures above 4,500 psi (310 bar). [3] The plant relies on low-sulfur coal from the Powder River Basin.
The Pingshan power station is a large modern coal-fired power station in China. The power station is divided into two phases with phase one consisting of two 660 MW units, each with scrubbing systems and cooling towers. [1] Phase two has one ultra-supercritical secondary reheat unit with a 1350 MW capacity.
It is the country's first super critical thermal power plant. The Khargone plant operates at an efficiency of 41.5 per cent, which is 3.3 per cent higher than the conventional super-critical ones, with steam parameters of 600 degree Celsius temperatures and 270 kg per centimeter square pressure.
Emerging technologies such as supercritical and ultra-supercritical thermal power stations operate at higher temperatures and pressures for increased efficiency and reduced emissions. Cogeneration or CHP (Combined Heat and Power) technology, the simultaneous production of electricity and useful heat from the same fuel source, improves the ...
