A third line, Bipole 3, was completed in 2018, running from the new Keewatinoow Converter Station along the west side of Lake Manitoba to the new Riel Converter station on the east side of Winnipeg. There are no intermediate switching stations or taps. All three bipolar systems have extensive ground return electrodes to allow use in monopolar mode.
Three-phase transformer with four-wire output for 208Y/120 volt service: one wire for neutral, others for A, B and C phases. Three-phase electric power (abbreviated 3ϕ [1]) is a common type of alternating current (AC) used in electricity generation, transmission, and distribution. [2]
Its 5 power stations produced 27.4 terawatt-hours of electricity in 2014-2015, meeting 75.7% of the provincial demand. Manitoba Hydro , the government-owned public utility is the main power generator in the province with 15 hydroelectric generating stations, 2 fossil-fuel plants and 4 diesel generators , for a total installed capacity of 5,701 MW.
Electricity is generated in Ontario from nuclear power, hydroelectric power, natural gas [85] and renewables such as wind, solar and biomass. Total production in 2017 was 132.1 TWh (i.e. 132.1 billion kWh.) [ 86 ] The various sources of generation used in 2017 are shown in the pie chart to the right.

A "transformer bank", widely used in North America: three single-phase transformers connected to make a 3-phase transformer. The low-voltage secondary windings are attached to three or four terminals on the transformer's side. In North American residences and small businesses, the secondary is often the split-phase 120/240-volt system. The 240 ...
The legislation capped retail prices at 4.3 cents per kWh and Ontario Power Generation (the successor of Ontario Hydro's electricity generation division) was to provide customers with a rebate for 100% of all electricity charges above that mark, retroactive to the market opening and continuing until 1 May 2006. Transmission and distribution ...
One voltage cycle of a three-phase system. A polyphase system (the term coined by Silvanus Thompson) is a means of distributing alternating-current (AC) electrical power that utilizes more than one AC phase, which refers to the phase offset value (in degrees) between AC in multiple conducting wires; phases may also refer to the corresponding terminals and conductors, as in color codes.
