About

Who is Starion Energy?

Registered as Starion Energy Inc., Starion Energy uses this legal name for state public-utility-commission filings and customer contracts. The trading name on bills is the shorter, more recognisable form.

The company is headquartered in Middlebury, CT, where it runs senior management, customer operations and regulatory liaison with state commissions.

Starion Energy was established in 2002. A longer track record means more years operating under state-commission rules and a wider history of customer feedback, billing and regulatory interactions.

Starion Energy operates independently — it is not part of a larger corporate group. This typically means faster decision-making but less wholesale-market scale.

Frequently asked

Starion Energy — answers to common questions

Starion Energy is regulated by the public utility commission in each state where it operates. Reliability is best judged against your own usage profile: read recent reviews, confirm the customer-service hours match when you actually need to call, and compare the unit rate against the utility's price-to-compare for your zip code.

Plans can typically be enrolled directly on Starion Energy's website or by calling 1-800-600-3040. Before signing up, always compare the unit rate (¢/kWh for electricity, $/therm for gas) against your utility's price-to-compare for your zip code.

You can switch your retail supplier at any time, though early termination fees (typically $50-$200) may apply if you are on a fixed-rate plan and within the contract term. Check your enrollment letter or Terms of Service for the exact figure. Switching back to your default utility supply is always free.
