In Norway, there is a small 55 kV single phase AC network for power supply of trains in the South, fed by Hakavik Power Station. A further power station, at Kjofossen feeds single phase AC directly in the overhead wire. In Denmark and Finland, 50 Hz is used for the main lines (if electrified) and the electricity comes from general suppliers. As ...
One supply phase (phase-to-neutral) from the utility is converted to split-phase for the customers. In electrical engineering, single-phase electric power (abbreviated 1φ) is the distribution of alternating current electric power using a system in which all the voltages of the supply vary in unison. Single-phase distribution is used when loads ...
Single-wire earth return (SWER) or single-wire ground return is a single-wire transmission line for supplying single-phase electrical power to remote areas at low cost. It is principally used for rural electrification, but also finds use for larger isolated loads such as water pumps. Single-wire earth return is also used for HVDC over submarine ...
Castaic Power Plant, the largest pumped-storage power station in California. Pumped-storage hydroelectricity is important means of large-scale grid energy storage that helps improve the daily capacity factor of California's electricity generation system. This is a list of all operational pumped-storage power stations in California.
Path 26 forms Southern California Edison's (SCE) intertie (link) with Pacific Gas & Electric (PG&E) to the north. Since PG&E's power grid and SCE's grid both have interconnections to elsewhere, in the Pacific Northwest (PG&E) and the Southwestern United States (SCE), Path 26 is a southern extension of Path 15 and Path 66, and a crucial link between the two regions' grids.
A traction substation, traction current converter plant, rectifier station or traction power substation (TPSS) is an electrical substation that converts electric power from the form provided by the electrical power industry for public utility service to an appropriate voltage, current type and frequency to supply railways, trams (streetcars) or ...

The Western Electricity Coordinating Council (WECC) coordinates a number of high voltage power links in western North America. [ 1 ] [ 2 ] [ 3 ] These links, known as WECC Intertie Paths , are not necessarily single transmission line, rather they are interties between various areas.
