It is uneconomical to provide such a large standby capacity at each station, so black-start power must be provided over designated tie lines from another station.

For example, one region may be producing cheap hydro power during high water seasons, but in low water seasons, another area may be producing cheaper power through wind, allowing both regions to access cheaper energy sources from one another during different times of the year.

During the 1970s, the 400 kV network, the new European standard, was implemented. The end user service voltage will progressively change to 230/400 V +/-10% since may 29, 1986.

Failures are usually associated with generators or power transmission lines tripping circuit breakers due to faults leading to a loss of generation capacity for customers, or excess demand.

Because the power is often generated far from where it is consumed, the transmission system can cover great distances.

In a synchronous grid all the generators must run at the same frequency, and must stay very nearly in phase with each other and the grid. Generation and consumption must be balanced across the entire grid, because energy is consumed as it is produced. For rotating generators, a local
