The electrical power grid that powers Northern America is not a single grid, but is instead divided into multiple wide area synchronous grids. [1] The Eastern Interconnection and the Western Interconnection are the largest. Three other regions include the Texas Interconnection, the Quebec Interconnection, and the Alaska Interconnection.
The workbook also includes a worksheet that displays the grid gross loss (%). Additional documentation is also provided with each eGRID release such as, a Technical Guide (PDF), Summary Tables, eGRID subregion map (JPG), NERC region Map (JPG), and release notes (TXT).
The Western Interconnection is a wide area synchronous grid and one of the two major alternating current (AC) power grids in the North American power transmission grid.The other major wide area synchronous grid is the Eastern Interconnection.
PJM Interconnection LLC (PJM) is a regional transmission organization (RTO) in the United States. It is part of the Eastern Interconnection grid operating an electric transmission system serving all or parts of Delaware , Illinois , Indiana , Kentucky , Maryland , Michigan , New Jersey , North Carolina , Ohio , Pennsylvania , Tennessee ...
Four electricity transmission projects serving the U.S. southwest, southeast and New England will get $1.5 billion in public funding to improve the grid's resilience and connect customers with ...
Interconnections can be tied to each other via high-voltage direct current power transmission lines , or with variable-frequency transformers (VFTs), which permit a controlled flow of energy while also functionally isolating the independent AC frequencies of each side. The Eastern Interconnection is tied to the Western Interconnection with six ...
The grid's capacity of long-distance transmission lines would need to quintuple over the next decade to handle that big surge in power demand outlined in the U.S. Energy Department's latest state ...
Within these physical grids, there are Independent System Operators and Regional transmission organizations, which are not-for-profit organizations that operate an area of the grid and are obliged to provide indiscriminate access to various suppliers (e.g. power plant owners, transmission line providers) to promote competition.
