Frequently asked

SJ Energy Partners — answers to common questions

SJ Energy Partners 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 SJ Energy Partners's website or by calling 1-866-882-7642. 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.
