The electric power transmission grid of the contiguous United States consists of 120,000 miles (190,000 km) of lines operated by 500 companies. The electrical power grid that powers Northern America is not a single grid, but is instead divided into multiple wide area synchronous grids . [ 1 ]
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 ...
The federal government sets general policies through the Department of Energy. Economic regulation of the distribution segment is a state responsibility, usually carried out through Public Utilities Commissions; the inter-state transmission segment is regulated by the federal government through the Federal Energy Regulatory Commission.
Rural electrification systems tend to use higher distribution voltages because of the longer distances covered by distribution lines (see Rural Electrification Administration). 7.2, 12.47, 25, and 34.5 kV distribution is common in the United States; 11 kV and 33 kV are common in the UK, Australia and New Zealand; 11 kV and 22 kV are common in ...
As one of the four power marketing administrations within the U.S. Department of Energy, the Western Area Power Administration (WAPA)'s role is to market wholesale hydropower generated at 57 hydroelectric federal dams operated by the Bureau of Reclamation, United States Army Corps of Engineers and the International Boundary and Water Commission.
The Bonneville Power Administration (BPA) is an American federal agency operating in the Pacific Northwest. BPA was created by an act of Congress in 1937 to market electric power from the Bonneville Dam located on the Columbia River and to construct facilities necessary to transmit that power. Congress has since designated Bonneville to be the ...
A federal judge has temporarily blocked plans to build a high-voltage power line across a Mississippi River wildlife refuge, saying he wants to see documents detailing the lead-up to the project's ...
Recognizing the impacts of transmission congestion, the inter-state nature of transmission needs, and the need to provide avenues for the facilitation of transmission capacity development, the US Congress passed the Energy Policy Act of 2005 which added Section 216 to the Federal Power Act (FPA; New Deal era legislation) which directs the US Department of Energy (DOE) to conduct a transmission ...
