	EIA - Energy Glossary - E
		Electric industry reregulation: The design and implementation of regulatory practices to be applied to the remaining traditional utilities after the electric power industry has been restructured.
		Electric power is measured by capacity and is commonly expressed in megawatts (MW).
		Electricity paid by household: The household paid the electric utility company directly for all household uses of electricity (such as water heating, space heating, air-conditioning, cooking, lighting, and operating appliances.) Bills paid by a third party are not counted as paid by the household.

		Solar electric systems (also called photovoltaic systems) may be an attractive option in locations where the electric power grid is not nearby.
		Electricity is often needed at a variety of remote sites, including vacation homes on islands and homes that are far from the commercial power grid.
		The cost of electricity for homes has increased steadily, and if a home is "all electric," the electric bill can be particularly high.

	Vehicle to Grid Power
		As cars and light trucks begin a transition to electric propulsion, powered by batteries, engines, or fuel cells, there is potential for a synergistic connection between such vehicles and the electric power grid.
		Battery powered electric vehicles are different than hybrid or fuel cell vehicles for this application in that they don't generate electricity.
		With fuel cell vehicles connected to the power grid and to a source of hydrogen, local, clean generating capability is added, and the utilization of the fuel cell itself could increase by an order of magnitude or more.

	Physics Today December 2004 - Articles: Transforming the Electric Infrastructure
		During the past century, the role of electric power has grown steadily in both importance (see figure 1) and scope.
		Physically, the grid is a network of wires and other devices, collectively called circuits, that weave together electrical loads (clusters of consumer demand) with the sources of electrical power generation.
		The power delivery system is largely based on technology developed in the 1950s or earlier and installed as much as 50 years ago.

	Electric power transmission - Wikipedia, the free encyclopedia
		Typically, power transmission is between the power plant and a substation near a populated area.
		AC power transmission is the transmission of electric power by alternating current.
		Therefore, the power lost is proportional to the resistance and inversely proportional to the square of the voltage.

	FuturePundit: Comment on Electric Power Grid Vulnerabilities Explored
		The grid is is more stable then most people think it goes in and out a lot because of weather patterns all the time.
		Electric power systems are NOT pipelines or road networks--graph theory has limited applicability to an electric power system.
		The electric power system in the United States is not third world, nor is it particularly vulnerable.

	Howstuffworks "How Power Grids Work"
		Electrical power is a little bit like the air you breathe: You don't really think about it until it is missing.
		It is only during a power failure, when you walk into a dark room and instinctively hit the useless light switch, that you realize how important power is in your daily life.
		The grid is quite public -- if you live in a suburban or rural area, chances are it is right out in the open for all to see.

	Electric Power Risk Assessment (Site not responding. Last check: 2007-09-22)
		This overview describes the structure of the electric utility industry, identifies the roles of key industry players, and explains the basic structure of an electric power transmission and distribution system with an emphasis on the mission, functions, and system components of a typical electric utility control center.
		The electric power industry is in the midst of a revolution driven largely by a mix of marketplace forces, and Federal legislative and regulatory activity.
		However, the impact of natural hazards on the power grid is the most manageable because utilities have years of experience with this threat and have designed facilities and infrastructure elements to minimize the impact of such events.

	FuturePundit: Electric Power Grid Vulnerabilities Explored
		Reka Albert, an assistant professor of physics at Penn State, has led a team examining the national electrical grid in the United States to look for vulnerabilities and her team has found that failures in a fairly small portion of the network can lead to a major disruption.
		Major flouts caused by failures in the grid, such as the one that affected the northeastern part of the country during the summer of 2003, incur tremendous economic, public-health, and security risks.
		However, the grid quickly becomes disconnected when the high-load transmission substations are selectively removed from the system--if the nodes that have the highest load are removed first, followed progressively by the nodes with successively lower loads.

	CS99 Y2K: Electric Power Grid
		The Power Grid is an infrastructure which allows electricity generated at every power plant in the continental United States and parts of Canada to be used wherever it is needed.
		Central Maine Power Company released a statement assessing their ability to restore power, "Repair crews' work was complicated not only by the continuing bad weather, which produces new calls for service restoration and fresh damage on just-repaired circuits, but by at least 80 poles broken by falling trees or vehicles skidding off icy roads" [5].
		The interdependence inherent in the structure of the power grid dictates that compliance is not jut a matter of individual plants or transmission systems testing their functionality, but is dependent on every section of the grid functioning with minimal disturbance.

	Infrastructure Report Card 2005
		The transmission grid is intended to be flexible, reliable and open to all exchanges, regardless of where the suppliers and consumers of energy are located.
		Electricity transactions that are highly desirable from a market standpoint may be quite different from the transactions for which the transmission grid was designed, and may stress the limits of safe operation.
		A safe, reliable electrical transmission grid is vital to the security and the economic health of the nation.

	Sandia National Laboratories - Electric grid reliability
		The nation's electric power grid is growing increasingly complex and interconnected, with a greater number of power buyers and sellers making a burgeoning number of transactions.
		Traditionally, power companies use simple, worst-case-avoidance software tools to monitor how power is þowing from place to place and to watch for the telltale signs of imminent outages.
		The report also suggests further study of a "distributed power grid": the idea that hundreds of traditional and nontraditional generation sources and storage devices could supply power to the grid at various times and locations, enabling less reliance on mega-scale power plants and giving the grid a broader, more stable foundation.

	Wired News: Hacking the Power Grid
		As electric utilities from California to Maine prepare for the era of deregulated competition, many are adopting customer-friendly Web sites.
		But the highly decentralized structure of the power plants -- generators are not connected to the networks which are hooked to the Internet -- means that the damage hackers can cause is limited, says Bruce Wallenberg, a professor of electrical engineering at the University of Minnesota, who has worked extensively with utilities.
		That's important, because while the networks controlling power grids are currently offline, the utilities will come to rely more and more on the Internet.

	AGU: Geomagnetic Storms Can Threaten Electric Power Grid
		Power systems in areas of igneous rock (gray) are the most vulnerable to the effects of intense geomagnetic activity because the high resistance of the igneous rock encourages geomagnetically induced currents (GICs) to flow in the power transmission lines situated above the rock.
		Faced with operating power systems in Earth's uncontrolled natural laboratory, the power industry and the scientific community are working to develop a better understanding of the causes and effects of this phenomenon.
		Power systems in areas of igneous rock are most vulnerable to the effects of intense geomagnetic activity.
