About

Who is Inspire Energy?

Registered as Inspire Energy Holdings, LLC, Inspire 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 Philadelphia, PA, where it runs senior management, customer operations and regulatory liaison with state commissions.

Inspire Energy was established in 2014. A longer track record means more years operating under state-commission rules and a wider history of customer feedback, billing and regulatory interactions.

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

Plan structure

What plan types does Inspire Energy offer?

Inspire Unlimited (flat monthly subscription)

Signature Inspire product: pay a single flat monthly fee for unlimited 100% clean electricity based on home size and zip code. No per-kWh metering on the supply portion.

Inspire Fixed Rate

Traditional per-kWh fixed-rate plan, 100% clean energy. Available in select markets for households whose usage is too variable for the flat subscription.

Renewable content: Every Inspire plan is matched 100% with Green-e certified renewable energy certificates sourced primarily from US wind farms, with smaller solar and biomass contributions.

Reach Inspire Energy customer service

Inspire Energy's customer service handles enrollment questions, billing, switching and complaints. Have your account number from a recent bill ready to speed up the call.

For service outages or downed wires, call your local utility — not Inspire. The retail supplier never handles the physical grid.
Inspire's phone hours are weekday-only (Mon-Fri 9 a.m. - 6 p.m. ET) — narrower than most competitors. Email and the in-app help center work outside those hours.
No signup or cancellation fees on the Unlimited subscription — but verify there is no ETF on any non-Unlimited fixed-rate plan you sign.

Frequently asked

Inspire Energy — answers to common questions

Inspire 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 Inspire Energy's website or by calling 1-866-403-2620. 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.
