While the concept of a "Global Super Grid" is a subject of extensive research and a long-term goal for the power industry, it is not yet a widespread reality. Intercontinental transmission today exists only in a few specific cases, primarily via HVDC (High-Voltage Direct Current) subsea cables that connect adjacent landmasses or islands.

Notable projects that link continents or major power markets include:

• The EuroAsia Interconnector: A planned project to connect the grids of Greece, Cyprus, and Israel.

• The Viking Link: A recently completed subsea cable linking the grids of the UK and Denmark.

• The Morocco-UK Power Link: A proposed 4,000 km subsea cable project to transmit solar and wind power from Morocco to the UK.

While these projects are significant engineering feats, they are not yet part of a global, interconnected grid.
