About

Who is Tara Energy?

Registered as Tara Energy, LLC, Tara 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 Houston, TX, where it runs senior management, customer operations and regulatory liaison with state commissions.

Tara Energy was established in 2000. A longer track record means more years operating under state-commission rules and a wider history of customer feedback, billing and regulatory interactions.

Tara Energy is part of the Just Energy Group Inc. group, which provides shared governance, financial backing and a broader pool of expertise in wholesale-market trading, hedging and regulatory work.

Frequently asked

Tara Energy — answers to common questions

Tara 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 Tara Energy's website or by calling 1-866-438-8272. 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.
