Grid

March 02, 2017 By: ironcore

The interconnected system of power lines and related equipment that delivers high-voltage electricity from power generating stations to substations, where it is transformed to a lower voltage for distribution to consumers. In the 48 lower states, the grid is comprised of three regional interconnected systems: the Eastern Interconnection, Western Interconnection, and Texas Interconnection; there is no single “national” grid. Alaska has separate Railbelt and Southeast Alaska grids, whereas Hawaii has island-based independent grids.
