The difference between energy suppliers vs. utilities is the roles they play in the market. In areas with energy choice, retail energy suppliers like Constellation supply energy to you, designing plans, setting rates and determining terms and benefits. Your local utility is responsible for delivering electricity. It builds and maintains power lines, substations and meters at your home and takes care of outages and repairs.
In many states, you get one combined bill that covers the utility costs and the energy the retail company supplies to you. Switching suppliers is seamless. When you choose Constellation as your energy supplier, the utility continues to deliver power to your home uninterrupted as the switch is made.
As America’s largest clean energy producer, we’re a leader in nuclear, wind, solar, and geothermal generation. We offer residential renewable energy plans in 11 states, matching your electricity usage with renewable energy certificates (RECs).
