Control Of The National Grid
The National Grid is the high-voltage electric power transmission network in Great Britain, connecting power stations and major substations, and has a synchronized organization such that electricity generated anywhere in Great Britain can be used to satisfy demand elsewhere. There are also undersea connections to northern France (HVDC Cross-Channel), Northern Ireland (HVDC Moyle), the Isle of Man (Isle of Man to England Interconnector), and the Netherlands (BritNed). The National Grid is controlled from the National Grid Control Centre which is located in St Catherine's Lodge, Sindlesham, Wokingham in Berkshire in South East England.
The national grid of the United Kingdom is required to distribute electric power generated in bulk to various grid supply points located across the UK and, in so doing, has to be able to match the supply of generated power to the demand for power which is continuously varying, sometimes gradually and predictably, and sometimes quite sharply. It has to do this and to maintain stability within specified standards of frequency and voltage dealing with both sudden changes in load and sudden changes in the available power output, the latter again being generally quite predictable but suffering random sudden changes as power stations fail from time to time.
Although all such large power grids have their own special historical and geographical peculiarities, they all tend to use methods of control and stabilisation similar to those used by the UK National Grid, to a greater or lesser extent.

Famous quotes containing the words control of, control and/or national:
“We long for our father. We wear his clothes, and actually try to fill his shoes. . . . We hang on to him, begging him to teach us how to do whatever is masculine, to throw balls or be in the woods or go see where he works. . . . We want our fathers to protect us from coming too completely under the control of our mothers. . . . We want to be seen with Dad, hanging out with men and doing men things.”
—Frank Pittman (20th century)
“For the mother who has opted to stay home, the question remains: Having perfected her role as a caretaker, can she abdicate control to less practiced individuals? Having put all her identity eggs in one basket, can she hand over the basket freely? Having put aside her own ambitions, can she resist imposing them on her children? And having set one example, can she teach another?”
—Melinda M. Marshall (20th century)
“...America has enjoyed the doubtful blessing of a single-track mind. We are able to accommodate, at a time, only one national hero; and we demand that that hero shall be uniform and invincible. As a literate people we are preoccupied, neither with the race nor the individual, but with the type. Yesterday, we romanticized the “tough guy;” today, we are romanticizing the underprivileged, tough or tender; tomorrow, we shall begin to romanticize the pure primitive.”
—Ellen Glasgow (1873–1945)
