Utility companies deliver the electricity you use to your home. Utilities also maintain the infrastructure through which the electricity travels to get to your home and also send you a bill for your usage. In Connecticut, they also can be suppliers.

Suppliers either buy or generate electricity. Either way, that electricity is delivered to your home by a utility company.

With multiple energy suppliers, consumers gain benefit through price and plan competition. UI suppliers include:

• Clearview Energy
• Constellation
• Direct Energy
• Public Power
• Verde Energy
