Electricity distribution in the context of "Hydro-Québec"

A stand-alone power system (SAPS or SPS), also known as remote area power supply (RAPS), is an off-the-grid electricity system for locations that are not fitted with an electricity distribution system. Typical SAPS include one or more methods of electricity generation, energy storage, and regulation.

Electricity is typically generated by one or more of the following methods:

Electricity retailing is the final sale of electricity from generation to the end-use consumer. This is the fourth major step in the electricity delivery process, which also includes generation, transmission and distribution.

Electricity delivery is the process that starts after generation of electricity in the power station, up to the use by the consumer.The main processes in electricity delivery are, by order:

• Transmission
• Distribution
• Retailing

Engie SA (stylised in all caps as ENGIE) is a French multinational electric utility company, headquartered in La Défense, Courbevoie. Its activities cover electricity generation and distribution, natural gas, nuclear power, renewable energy, district energy, and the petroleum industry. It is involved in both upstream (engineering, sale, operation, maintenance) and downstream (waste management, dismantling) activities.

Engie supplies electricity to 27 countries in Europe and 48 countries worldwide. The company, formed on July 22, 2008, by the merger of Gaz de France and Suez, traces its origins to the Universal Suez Canal Company founded in 1858 to construct the Suez Canal. As of 2022, Engie employed 96,454 people worldwide with revenues of €93.86 billion.

A power outage, also called a blackout, a power failure, a power blackout, a power loss, a power cut, or a power out is the complete loss of the electrical power network supply to an end user.

There are many causes of power failures in an electricity network. Examples of these causes include faults at power stations, damage to electric transmission lines, substations or other parts of the distribution system, a short circuit, cascading failure, fuse or circuit breaker operation.

An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, electric multiple units, trolleybuses or trams. The generic term used by the International Union of Railways for the technology is overhead line. It is known variously as overhead catenary, overhead contact line (OCL), overhead contact system (OCS), overhead equipment (OHE), overhead line equipment (OLE or OHLE), overhead lines (OHL), overhead wiring (OHW), traction wire, and trolley wire.

An overhead line consists of one or more wires (or rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regularly spaced intervals along the track. The feeder stations are usually fed from a high-voltage electrical grid.
