Plate tectonics is a scientific theory describing the large-scale motion of the plates making up the Earth's lithosphere since tectonic processes began on Earth between 3.3 and 3.5 billion years ago.
A plate heat exchanger is a type of heat exchanger that uses metal plates to transfer heat between two fluids.
A plate-fin heat exchanger is a type of heat exchanger design that uses plates and finned chambers to transfer heat between fluids.
A plasmonic-enhanced solar cell is a type of solar cell that converts light into electricity with the assistance of plasmons, but where the photovoltaic effect occurs in another material.
A plasmon is a quantum of plasma oscillation.
Plasma gasification is an extreme thermal process using plasma which converts organic matter into a syngas (synthesis gas) which is primarily made up of hydrogen and carbon monoxide.
In a plasma gasifier a high-voltage current is fed to a torch, creating a high-temperature arc.
Like a gas, plasma does not have definite shape or volume.
Percentage of the total load that the plant can increase in a minute (with an already running engine) to provide ancillary services.
Typical size of the power plant.
Lowest unit or plant level load that can be maintained for extended periods of time.
Operation when load is too low or no revenue is being generated.
The ability of a power plant to vary its output depending on the load required.
Time it takes to decrease output from 100% to 0%, disconnect from grid.
Start time based on hot standby (preheated to a higher temperature or operated in the last 6 hours).
Approximate efficiency at generator without pumps based on ISO 3046 conditions and 5% tolerances.
The minimum power source continually supplied on a daily basis.
Planned maintenance is a scheduled service visit carried out by a competent and suitable person to ensure that an item of equipment is operating correctly and to therefore avoid any unscheduled breakdown and downtime.
The world's largest solar-powered boat and in 2012 the first ever solar electric vehicle to circumnavigate the globe.
Pitch regulation thus allows the wind turbine to actively change the angle of attack of the air on the blades.
