How to switch Connecticut electricity companies

While Connecticut residents have access to multiple electricity providers, understanding the switching process helps guarantee a smooth changeover between companies.

You'll need to plan ahead since suppliers require up to two weeks to process applications.

Here's how to switch your electricity company in Connecticut:

• Compare rates using tools like the one on our page
• Select a supplier and plan that fits your needs
• Submit enrollment at least two days before your meter read date
• Wait for the switch to occur on your next billing cycle

Remember that if you don't choose an alternative supplier, you'll automatically receive Standard Service through UI or Eversource, with rates that change every January 1st and July 1st.

When is the best time to switch energy providers in Connecticut?

After understanding how to switch providers, knowing the ideal timing for making the switch can save you money and prevent service disruptions.

The best time to switch is at least ten days before your next meter reading date, which you'll find on your electric bill.

Key timing considerations:

• Standard Service switches take two business days
• Supplier changes require 2-3 weeks for completion
• Switches activate on your next meter reading date
• You'll need to settle any outstanding balances first

Consider your usage patterns and contract terms when timing your switch.

Longer contracts often offer better rates but may have stricter terms and potential cancellation fees.

How deregulated electricity works in Connecticut

Since Connecticut passed its deregulation law in 1998, you've had the power to choose your electricity supplier rather than relying solely on your utility company.

Under this system, utilities focus on delivering power through transmission and distribution networks, while generation is open to competition.

Here's how it works:

• Your utility company handles the physical delivery of electricity
• You can choose a competitive supplier for the electricity itself
• The ISO New England manages the wholesale market
• If you don't choose a supplier, you'll receive standard service from your utility

Despite deregulation's promise of lower costs through competition, Connecticut continues to have some of the highest electricity rates nationwide. This is why choosing your provider carefully is important.

Types of electricity plans in Connecticut

When choosing an electricity plan in Connecticut, you'll see three main options that have different pros and cons:

• Fixed-rate: Predictable bills with terms from 6-36 months
• Variable rate: Monthly rate changes based on market prices
• No-contract: Quick activation and freedom to switch providers

Before selecting a plan, evaluate your energy usage patterns and compare offerings from different providers.

Remember that Eversource (formerly Connecticut Light & Power) and United Illuminating handle the physical infrastructure regardless of your chosen supplier.
