Electric supply is related to the National Grid in that the National Grid is composed of many supply lines that direct electricity to the National Grid, and this in turn powers the country.
transformers
The voltage of the French National Grid is 2000 mw high voltage. It is a direct current electrical interconnector between the British and French transmission.
National grid is nothing but a net work (power system) of many different generation points across a region / country to feed to different end user points.
Wikipedia has figures for electrical generation ie input to the grid, rather than output from the grid, but it's the same apart from transmission losses. For 2006, the latest given, it is a total of 4.063 billion megawatthours. Since there are 8760 hours in a year, this gives the average power output as 578,000 MWe. This compares to a total nameplate rating for all the plants in the country of 1,075,171 MWe.See Wikipedia 'Energy use in the United States'
They're connected by cables. The wind spins the turbine - generating electricity. The electricity is fed into the national grid by cables.

By overhead cables, supported on masts, at very high voltage, to reduce the effects of resistance in the wires.
At the National Grid was created in 2005.

Because the power needed to make them work is delivered by a national 'grid' of electrical cables. There is no way to actually transmit power to an appliance through the air. It must be deilvered by cables.
The population of National Grid plc is 2,012.
National Grid plc was created in 1990.
In the National Grid there are 876 thousand pylons.
No, solenoids are an electrical switch. You may be thinking of transformers but they are not cables either.
The national grid is a means of distributing electricity, there is no need for a dynamo (which produces electricity) in the national grid. However, dynamos (generators) are needed in the power stations.
The cables are undergrounded in built up areas. The reason they're left as pilons where there is space for them is because it is cheaper to build, quicker to spot a fault and easier to maintain. Underground cables cost around twenty times as much as overhead cables, but are necessary in cities and built up areas.
