It is operated as an independent AC grid for physical reasons. [12] The Quebec Interconnection is tied to the Eastern Interconnection with four high-voltage direct current power transmission lines , and with one variable-frequency transformers (VFTs) line, which isolate the unsynchronized AC frequencies of each side.
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.
The 735 kV power line is said to lessen the environmental impact of power lines, as one single power line operating at this voltage carries the same amount of electric power as four 315 kV power lines, which would require a right-of-way wider than the 80.0–91.5 metres (262.5–300.2 ft) [29] [30] width required for a single 735 kV line.
The Western Interconnection is a wide area synchronous grid and one of the two major alternating current (AC) power grids in the North American power transmission grid.The other major wide area synchronous grid is the Eastern Interconnection.
Long distance HVDC lines carrying hydroelectricity from Canada's Nelson River to this converter station where it is converted to AC for use in southern Manitoba's grid. A high-voltage direct current (HVDC) electric power transmission system uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems.

The demand, or load on an electrical grid is the total electrical power being removed by the users of the grid. The graph of the demand over time is called the demand curve. Baseload is the minimum load on the grid over any given period, peak demand is the maximum load. Historically, baseload was commonly met by equipment that was relatively ...

Today's power industry is far more than a collection of power plants and transmission lines. Maintaining an effective grid requires management of three different but related sets of flows – the flow of energy across the grid; the exchange of information about power flows and the equipment it moves across; and the flow of money between ...
