A transformer is an electrical device that takes electricity of one voltage and changes it into another voltage. You'll see transformers at the top of utility poles and even changing the voltage in a toy train set.
Because then every town has the same voltage: before, if there was a sudden demand for electricity in one town- nearby towns couldn't help for they had different voltages. So, the town couldn't cope with the electricity demand but now it can because of the National Grid.
centimeter grid paper is a grid paper having many square boxes each of 1 cm.
Hydroelectric energy is electricity and is put on the national grid for use by the public. It is used for pretty much every modern process of anything, in some way or another.

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.
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.
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 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.
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.
