simply designing for average demand), utilities will face problems throughout their planned lifetime.
Whether it is a single catastrophic event that was not foreseen, or a planned event by utility companies such as for maintenance, or poor planning (e.g. Interruption in service on the electric grid may occur for a myriad of reasons. Įlectric grid failure Brownout vs Blackout Without a reliable system, sustainable energy production practices and reasonably priced energy, there can be no sustainable long term growth.

In most congested transportation networks, "Stop and Go" conditions exist where free flow of traffic is limited. This is analogous to transportation networks when traffic flow exceeding roadway capacity. Also, high demand during peak hours has led to a congested state of service delivery. Some renovations could save energy due to power losses that occur during the transmission and distribuition phases in the electric grid. residential properties) receive 120 V or 240 V.ĭue to aging infrastructure, the current state of the electric grid needs renovations to meet current demand. This helps reduce losses on the transmission lines, however consumers need the voltage to be stepped-down to lower a voltage such as 13 kV and 4 kV for large energy consumers (e.g. Generation-Transmission-Distribution on the Electric Grid.Īs a result of the increased demand, there is need for a more efficient distribution and consumption network, both of which are problems addressed by a "smart grid." Upon generation, step-up transformers are used to 'step-up' voltage for transmission across the grid. Aging infrastructure coupled with increased domestic consumption has complicated electricity distribution and has caused limited outages. The U.S Electric grid is independently owned and operated by various players in the industry. The economic aspects of the electric grid have received a lot of attention recently due to shifting attention towards the electric grid's reliability and robustness. The transmission and distribution of electricity is of interest from geographical, social and economic points of view. The electric grid shares spatial similarities to other networks such as the internet where individual links are observed to have a physical location. The following is a list of energy sources as arranged in the order of power it generates into the national grid. According to the U.S Energy Information Administration there are six major sources of energy for electric generation. Electric generation varies with the source of energy. Įlectric generation is the first step in supplying energy to consumers. It is also connected to more than 300,000 miles of transmission lines. According to the Department of Energy (DOE), the electric grid consists of more than 9,200 electric generating units with more than 1,000,000 megawatts of generating capacity. Its complex interactions with human beings has led it to be dubbed an ecosystem. The U.S electric grid is nearly a century old and is the largest interconnected physical network.
