Generation: Electricity is generated at power plants, which can use various energy sources such as coal, natural gas, nuclear, hydroelectric, wind, or solar power. These power plants produce high-voltage electricity.
Step-up Transformer: Before distribution, the electricity is typically passed through a step-up transformer to increase its voltage. Higher voltage transmission reduces energy loss during long-distance transportation.
Transmission: The high-voltage electricity is transmitted through a network of high-voltage power lines and substations. These power lines can span long distances, carrying electricity from the power plants to regional distribution centers.
Step-down Transformer: At substations located closer to residential and commercial areas, the voltage is reduced through step-down Transformers. This process lowers the voltage to a level suitable for distribution to homes and businesses.
Distribution Lines: Lower-voltage electricity is then distributed through a network of power lines and transformers at the local level. These distribution lines typically consist of overhead wires or underground cables.
Distribution Transformers: Near or within residential and commercial areas, distribution transformers further reduce the voltage to levels suitable for household use, typically 120/240 volts in North America or 230 volts in many other parts of the world.
Service Lines: From the distribution transformers, electricity is sent through service lines to individual homes and businesses. These service lines connect to the main electrical panel or meter at each building.

A modern power grid consists of many voltages and currents, all being interconnected by transformers, which trade off voltage and current. A typical power generator usually generates electricity at a few thousand volts AC, which is then stepped up to around 120kv for distribution, then stepped down to around 30kv, for secondary distribution, then finally down to 240v/120v for domestic use. Engineers typically measure the voltage of AC circuits using "RMS voltages" (Root Mean Squared voltages) This convention is used because of the varying nature of AC, and relates the varying AC voltage to an effective DC voltage. RMS Voltage for typical AC =Peak voltage / Square root(2) which is approximately equal to peak voltage* 70%
Power loss during power transmission is predominantly due to the current drawn, which heats the wires. Power dissipated is current x voltage and voltage is current x resistance, so in any wire with fixed resistance the power loss is proportional to the square of the current flowing. The higher the voltage you use to transmit the power down the distribution network the lower is the current, hence power is distributed at the highest voltage that is practical, then the voltage is dropped to the domestic level at the destination sub-station or by a transformer on the power line pole. Major distribution systems operate at over 100 kV, with regional ones at lower voltage.Additional Answer33 kV (not 'kv'!) is the primary distribution voltage, not a transmission voltage, used in the UK. Other distribution voltages are 66 kV (not very common) and 11 kV. Transmission systems operate at 400 kV and 275 kV.

No, nuclear energy is not typically used for domestic purposes in homes due to safety and regulatory concerns. Nuclear power plants are large facilities that generate electricity on a large scale for distribution to the grid.
Electricity began to be installed in domestic homes in Tyne and Wear in the late 19th century. By the early 20th century, most homes in the region had access to electricity for lighting and other electrical appliances.
