Electrical Power Generation and Distribution - An Introduction A generation plant creates the electricity people use. There are several types, including natural gas, hydro, nuclear and coal-powered facilities. Renewable energy sources include solar panels, wind turbines and biomass converter stations. Most of the electricity generated in Ontario comes from nuclear, hydro or natural gas facilities. Once the electricity is created, the voltage is increased ('stepped up') by a transformer to allow it to travel over long distances. The voltages may range between 115 kilovolts (kV) up to 500 kV, depending on the distances involved. The electrical power is distributed to municipalities over lines on lattice towers or poles. Once the electricity lines reach town, the voltage of the electricity is brought down ('stepped down') using a transformer sub-station. At this stage, voltages may be reduced to a range between 5kV and 50kV. This is the voltage for power lines strung along poles in town. Electricity is further reduced when it reaches the lines coming into your home, usually by small transformers attached to nearby poles. Standard voltages for residences are usually 120 V or 220 V. Electrical substations have various functions. They use circuit breakers and switches to turn power lines on or off, or divert electricity to different lines. They can also convert the voltages of lines from one level to another. For further information, please refer to the following link: Further reading...
