Only One Skips the Credit Check

Pronto Power doesn't run your credit and offers prepaid. Rhythm Energy runs your credit and might want $200-400 upfront.

What Actually Differs

Pronto Power and Rhythm Energy deliver the exact same electricity through the exact same wires. The electrons don't care whose logo is on your bill. What differs: the price, the service when something goes wrong, and the fine print in contracts.

Who's Behind These Companies

Pronto Power: Owned by Summer Energy Holdings (OTC: SUME). 15 years in Texas—they've survived enough grid crises to prove they won't fold mid-contract. Based in Houston, Texas.

Rhythm Energy: Owned by Goldman Sachs (West Street Capital Partners VII). 5 years in Texas—that track record matters when you're signing a multi-year contract. Based in Houston, Texas.

What They Actually Sell

Pronto Power offers prepaid. They have prepaid—no credit check, no deposit, just pay as you go.

Rhythm Energy offers fixed-rate, time-of-use, green, solar-buyback. They sell "green" plans (mostly accounting—same electrons, but they buy renewable credits).

The Money Part

Pronto Power: No deposit. Period. No credit check needed.

Rhythm Energy: Deposit depends on credit—expect $200-400 if your score is below 600.
