Is Constellation Energy a good choice in Ohio?

Constellation Energy is one of Ohio's largest and most established retail electricity providers (part of Exelon), with reliable service and a broad range of plans across every major TX utility territory. It's both reputable and competitively priced.

Constellation Energy's cheapest clean fixed rate is 10.69¢/kWh, while the lowest fixed rate available in the same Ohio territories runs about 7.19¢/kWh. You're paying a premium for the brand — fine if service and name recognition matter most to you, but you can often find a lower rate.
