A mini-grid is an aggregation of electrical loads and one or more energy sources operating as a single system providing electricity and possibly heat, isolated from a main power grid. A modern mini-grid may include renewable- and fossil fuel-based power generation, energy storage, and load control.
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 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.
An electrical grid may have many types of generators and loads; generators must be controlled to maintain stable operation of the system. In an electric power system, automatic generation control (AGC) is a system for adjusting the power output of multiple generators at different power plants, in response to changes in the load. Since a power ...
In 1997, Transpower adopted a strategy known internally as “the glide path”, and minimised spending on the grid and renewing assets. The rationale for this strategy was based on the expectation that there would be widespread installation of distributed generation (electricity generated close to where it is used), and that this would significantly reduce the need to expand and renew the grid.
The demand, or load on an electrical grid is the total electrical power being removed by the users of the grid. The graph of the demand over time is called the demand curve. Baseload is the minimum load on the grid over any given period, peak demand is the maximum load. Historically, baseload was commonly met by equipment that was relatively ...
The term smart grid is most commonly defined as an electric grid that has been digitized to enable two way communication between producers and consumers. [1] The objective of the smart grid is to update electricity infrastructure to include more advanced communication, control, and sensory technology with the hope of increasing communication between consumers and energy producers.
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.
