Energy Choice

Q: What is Energy Choice and what is its purpose?

A: Energy Choice is a term used to describe the situation where consumers have the option to select who provides their electric generation supply. In competitive or restructured markets, the traditional monopoly structure for supplying electricity to retail consumers is opened to choice and competing suppliers. This happens via a legislative or regulatory initiative and is addressed at the state level. Energy Choice is still in its early stages, yet customers are already realizing its benefits - more competitive energy prices, improved customer service and technological and product innovations have been spurred by retail competition.​


Q: How can a competitive supplier like Constellation offer a lower price than my utility?

A: As a competitive supplier of electricity and natural gas, Constellation can provide pricing options that more closely reflect the current market.​


Q: What stays the same if I choose a new supplier?

A: Everything else. You will continue to receive reliable service. Service components such as wires, pipelines, meters, and transformers will remain where they are. Physical modifications are not required because your energy is delivered through the same transmission and distribution system owned and operated by your utility. Your local utility will continue to be responsible for delivering electricity and natural gas, and costs associated with those delivery services will continue to be charged by your local utility at your current rates.

You will also still receive one bill from your utility. Your bill will appear the same as it has in the past. Your utility will continue to service all equipment—such as your meter, wires, and pipelines— as well as respond to any power outages.​


Q: If I pursue Energy Choice and select a new supplier, what changes?

A: Choice allows you to pursue pricing options and plans for the generation supply portion of your energy bill that may be lower than what your utility is currently offering. You may also experience improved customer service when you choose a new energy supplier.​


Renewable Energy 

Q: What is Renewable Energy?

A: Renewable Energy, also known as green power, is energy generated by the sun, wind, earth, and water. These resources replenish themselves naturally. Renewable energy fuels include solar, landfill biomass, wind and geothermal.​
