Our vast energy network is key to ensuring our customers receive economical, reliable, and clean energy. We continually invest in our infrastructure to ensure that we deliver the most reliable and efficient energy to our customers in our eight-state region. We monitor our grid 24 hours a day, seven days a week to ensure consistent reliability and the ability to immediately react should anything go wrong.
Power generation is complex, and delivering electricity to your home or business is a multi-step process:
Xcel Energy produces power at our power stations, using a diverse mix of fuels that includes biomass, coal, nuclear, and natural gas, to produce electricity by creating steam to turn a turbine. We also harvest clean energy directly from water, the sun, or wind.
From these power stations, high-voltage transmission lines carry the electricity to local substations. By transporting electricity across vast distances, our transmission lines connect with other regional transmission systems to ensure electric reliability.
With over 20,000 miles of transmission lines, we have a robust transmission network. Learn more about our capabilities, current projects, and our future transmission plans.
The outgoing electric distribution lines from substations carry electricity that has been converted from incoming transmission line voltage to lower, more usable levels. The equipment within substations also protects the lines from damage and controls the flow of electricity.
Electricity travels over distribution power lines from substations directly to homes and businesses in your neighborhood. We own and operate thousands of miles of above ground and underground distribution lines. Today only 20% of new line construction is overhead. Get more information before undergrounding electric distribution lines in Minnesota, North Dakota, or South Dakota (PDF).
A transformer converts the distribution level voltage to levels suitable for your home or business, and carries power to the end user. Transformers look like a large can and are often mounted on poles, but sometimes can be placed under ground.
Our Grid Modernization project is preparing us for how quickly technology in the utility industry is changing. Through the 15-year program, we are working to create a state-of-the-art grid that successfully integrates solar, microgrids, distributed energy resources, smart grid technologies, electric battery storage and other new energy technologies.
To learn more about how the grid enhances our customers' experience and promotes choice, view our Advanced Grid (PDF).
