Russian nuclear microreactor Shelf-M. A nuclear microreactor is a type of nuclear reactor which can be easily assembled and transported by road, rail or air. [1] Microreactors are 100 to 1,000 times smaller than conventional nuclear reactors, and range in capacity from 1 to 20 MWe (megawatts of electricity), compared to 20 to 300 MWe (megawatts of electricity) for small modular reactors (SMRs ...
A flywheel-storage power system uses a flywheel for energy storage, (see Flywheel energy storage) and can be a comparatively small storage facility with a peak power of up to 20 MW. It typically is used to stabilize to some degree power grids, to help them stay on the grid frequency, and to serve as a short-term compensation storage.

It was the world's most powerful solar power tower until the Ivanpah Solar Power Facility in California became operational in 2014. The 20 megawatt (MW) solar power tower produces electricity with large movable mirrors called heliostats. [1] [2] Construction of PS20 was started in 2006 and it commenced operation in 2009.
Declared net capacity (DNC) is a measure of the contribution that a power station makes to the overall capacity of a distribution grid. It is measured in megawatts (MW), or in megawatts electrical for a thermal power station. DNC is sometimes expanded as developed net capacity in British English; The two expansions have exactly the same meaning.
The power plant was built in 1920 to a design by the architect Olaf Nordhagen. It opened with two Pelton turbines at 20 megawatts (27,000 hp) each delivering power at 25Hz. In 1922, a third one was opened. At the time these were the largest turbines in operation in Norway.
The only ships to use these nuclear reactors are the Nimitz-class supercarriers, which have two reactors rated at 550 MW th each. These generate enough steam to produce 140,000 shaft horsepower (104 MW) for each pair of the ship's four shafts [ 2 ] – two per propulsion plant – plus approximately 100 MW of electricity.
