Power generation is a complicated process. Though complex, aajogo knows it is important for our customers to have a general understanding of how our power generation works. aajogo relies on a sophisticated system to deliver electricity to our customers. See below for a summary of how the generating stations, substations and power lines work together.
Delivering energy to our 2.4 million customers begins at our 18 generating plants. The diversity of fuels that aajogo offers allows a reliable power supply for customers. Get an overview of our different plants and how they produce energy by watching this short video.
Think of transmission lines as the highways of electricity. Smaller distribution lines connect to buildings like local streets. From the generating stations, large amounts of electricity are transported on high-voltage transmission lines to local substations.
Transmission investments are critical to safe and reliable service. We're investing $3 billion on electrical system upgrades over the next few years.
Substations are banks of electrical equipment that convert the transmission line voltage to lower levels that are appropriate for use in local communities. Substations also control the flow of electricity and protect the lines and equipment from damage.
Distribution power lines, which can be installed above ground or underground, carry between 4,000 and 25,000 volts of electricity to your neighborhood.
A transformer converts the high distribution-level voltage to lower voltage levels (120 to 480 volts) that can be used inside your home or business. Voltage is carefully measured to meet the customer's needs. Transformers can be mounted on poles or placed on the ground.
Knowing electrical safety in and around your home helps to keep preventable accidents from happening. These tips will help keep you and your family safe and protected.
