Plate tectonics

energy

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.

Plate heat exchanger

energy

A plate heat exchanger is a type of heat exchanger that uses metal plates to transfer heat between two fluids.

Plate fin heat exchanger

energy

A plate-fin heat exchanger is a type of heat exchanger design that uses plates and finned chambers to transfer heat between fluids.

Plasmonic enhanced solar cell

energy

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.

Plasmon

energy

A plasmon is a quantum of plasma oscillation.

Plasma gasification

energy

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.

Plasma gasifier

energy

In a plasma gasifier a high-voltage current is fed to a torch, creating a high-temperature arc.

Plasma

energy

Like a gas, plasma does not have definite shape or volume.

Plant ramp rate (%/min)

energy

Percentage of the total load that the plant can increase in a minute (with an already running engine) to provide ancillary services.

Plant output (MW)

energy

Typical size of the power plant.

Plant minimum load (%)

energy

Lowest unit or plant level load that can be maintained for extended periods of time.

Plant low load operation

energy

Operation when load is too low or no revenue is being generated.

Plant load following

energy

The ability of a power plant to vary its output depending on the load required.

Plant fast stop

energy

Time it takes to decrease output from 100% to 0%, disconnect from grid.

Plant fast start time(min)

energy

Start time based on hot standby (preheated to a higher temperature or operated in the last 6 hours).

Plant efficiency (%)

energy

Approximate efficiency at generator without pumps based on ISO 3046 conditions and 5% tolerances.

Plant baseload

energy

The minimum power source continually supplied on a daily basis.

Planned maintenance

energy

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.

PlanetSolar

energy

The world's largest solar-powered boat and in 2012 the first ever solar electric vehicle to circumnavigate the globe.

Pitch regulated wind turbine

energy

Pitch regulation thus allows the wind turbine to actively change the angle of attack of the air on the blades.
