What is the primary purpose of utility substations?

The primary purpose of utility substations is to monitor and ensure the reliable and efficient delivery of power into the distribution grid. Substations play a crucial role in transforming voltage levels between high transmission voltages and lower distribution voltages, and in managing the flow of electrical power in various directions, ensuring stability and efficiency in the power supply to residential, commercial, and industrial users.
