Electricity Delivery and its Environmental Impacts | Energy

About Electricity DeliveryElectricity Delivery in The United StatesEnvironmental Impacts of Electricity DeliveryAfter a centralized power plantgenerates electricity, the electricity must be delivered to the end-user. This delivery happens in three steps: 1. Transmission. Centralized power plants produce high-voltage electricity to facilitate the transmission of the electricity over long distances and lessen the amount of electricity lost to friction in the wires. High-voltage transmission lines typically carry the electricity to a substation. 2. Substation.Substations are used to condition electricity as it moves through the grid. Substations can include switching, protection, and control equipment; capacitors; voltage regulators; and transformers. Substations can either “step down” or “step up” high- or low-voltage electricity to prepare it for further transmission or distribution. 3. Distribution. The distribution portion of the electric grid comprises lower voltage power lines that deliver electricity to end-users. Distribution networks tend to span shorter distances and involve delivery o...Get price
