Power electronics is the application of solid-state electronics to the control and conversion of electric power.

Power engineering, also called power systems engineering, is a subfield of electrical engineering that deals with the generation, transmission, distribution, and utilization of electric power, and the electrical apparatus connected to such systems.

Defined as the ratio of the real or active power absorbed by the load to the apparent power flowing in the circuit.

A network of interconnected transmission lines for the delivery of electricity.

Power-line communication carries data on a conductor that is also used simultaneously for AC electric power transmissionor electric power distribution to consumers.

A loss of power to the end user.

Power over Ethernet, or PoE, describes any of several standards or ad hoc systems that pass electric power along with data on twisted pair Ethernet cabling.

A single engine or facility that produces electrical power by various means.

Power plant engineering or power station engineering is a division of power engineering, and is defined as "the engineering and technology required for the production of central station electric power."

A Wartsila design tool to assist clients in identifying their needs for a power plant.

A power purchase agreement (PPA), or electricity power agreement, is a contract between two parties, one which generates electricity (the seller) and one which is looking to purchase electricity (the buyer)

A power station, also referred to as a power plant and sometimes generating station or generating plant, is an industrial facility for the generation of electric power.

Electric power transmission system that carries high voltage direct current (HVDC). Commonly between 100kV and 800kV.

Installations for the generating, conversion, storage and distribution of electrical energy.

All components and systems necessary to supply the DP system with power.

Power to gas is a technology which converts electrical power to a gas fuel.

A process which allows the creation of carbon neutral and renewable synthetic fuels by capturing CO2 from the air.

The power-flow study, or load-flow study, is a numerical analysis of the flow of electric power in an interconnected system.

A powerline technician (PLT) is a tradesman who constructs and maintains electric power transmission and distribution lines.

A powerline worker is a tradesman who constructs and maintains electric power transmission and distribution lines.
