It comes from the street, via either an underground cable or an overhead line operating at the voltage that you are supplied with.
Those lines or cables are supplied from a transformer that is probably within about 200 metres of your home. The transformer is supplied at a higher voltage and so on via various high-voltage Transformers back to the grid and from there to the generating stations.
In the UK the local supply works at 240 volts which is also described as 415 v three-phase. The transformer supplies up to 2-300 homes and takes its power at 11 kV three-phase, and that is supplied at 33 kV from a transformer that is capable of supplying a small town of 5000-10,000 people. Towns are connected via a regional grid at 132 kV that connects major substations, and they in turn are supplied from the supergrid at 275 kV or 400 kV, that is 400,000 volts.
