China's electricity suppliers plan to complete by 2020 its ultra high voltage AC synchronous grid linking the current North, Central, and Eastern grids. [30] When complete, its generation capacity will dwarf that of the UCTE Interconnection. Unified Smart Grid unification of the US interconnections into a single grid with smart grid features.
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 ...
The Texas Interconnection is an alternating current (AC) power grid – a wide area synchronous grid – that covers most of the state of Texas. The grid is managed by the Electric Reliability Council of Texas (ERCOT). The Texas Interconnection is one of the three minor grids in the North American power transmission grid.
Nemo Link is a 1,000 MegaWatt HVDC submarine power cable between Richborough Energy Park in Kent, the United Kingdom and Zeebrugge, Belgium. [1] The project is a joint venture between British National Grid and Belgian Elia. [1]
