It is operated as an independent AC grid for physical reasons. [12] The Quebec Interconnection is tied to the Eastern Interconnection with four high-voltage direct current power transmission lines , and with one variable-frequency transformers (VFTs) line, which isolate the unsynchronized AC frequencies of each side.
The MRO region lies within the Eastern Interconnection and occupies upper midwestern North America, covering all of the states of Minnesota, North Dakota and Nebraska, portions of the states of Arkansas, Illinois, Iowa, Kansas, Louisiana, Michigan, Missouri, Montana, New Mexico, Oklahoma, South Dakota, Texas, and Wisconsin, as well as the ...

The Tres Amigas SuperStation (lit. ' Three Friends SuperStation ') was a project proposed in 2009 to unite North America’s two major power grids (the Eastern Interconnection and the Western Interconnection) and one of its three minor grids (the Texas Interconnection), with the goals of enabling faster adoption of renewable energy and increasing the reliability of the U.S. grid.

The Eastern Interconnection is one of the two major alternating-current (AC) electrical grids in the North American power transmission grid. The other major interconnection is the Western Interconnection. The three minor interconnections are the Quebec, Alaska, and Texas interconnections. All of the electric utilities in the Eastern ...
A balancing authority (BA) is an entity in the US electric system (as well as in parts of Canada and Mexico) that is responsible for grid balancing: resource planning and unit commitment ahead of time, maintenance of the load-interchange-generation balance within a balancing authority area (also known as a control area) and support for real-time load-frequency control.
