Energy Suppliers with the Best Ratings and Service

What Makes a Great Retail Energy Provider?

When it comes to choosing an alternative energy supplier, getting the cheapest energy rate isn’t the only criteria. There are other important factors such as the length of the contracts, cancellation fees, sign-up bonuses or how hard is it to actually make the switch. The reliability of the power supply can be important and also hidden fees that may apply. 

To find the best energy provider in the U.S., we looked at ratings for customer satisfaction, service and the best rates from energy suppliers across the nation’s deregulated electricity and natural gas markets. Since your local utility company is still responsible for delivering energy to customers, it’s important for the provider to work well with the local utility.

America's Biggest Energy Companies

Biggest Market Value

Great market value, for an energy company, may not necessarily mean their rates are cheap or their service is great. It’s certainly important for investors though, and it often means that the company is doing something right. According to the statistics portal Statistica, the nation’s largest electricity and natural gas utilities in 2018 by market value were, NextEra, Duke Energy and Southern Company.

Juno Beach, Florida-based NextEra Energy Inc. is an investment company investing in power generation, transmission and distribution with a market capitalization of $75.8 billion. Duke Energy Corporation out of Charlotte, North Carolina is one of the largest electric power holding companies in the U.S. with a market capitalization of $56.3 billion.

The American Customer Satisfaction Index (ACSI) and JD Power track customer evaluations of the quality of products and services for utilities across the nation. The ACSI is a national economic indicator of customer satisfaction for municipal and cooperative energy utilities as well as for investor-owned utilities. JD Power provides rankings for different size utilities in different regions across the nation.

It’s followed by Atmos Energy and Southern Company, which scored 80 and 79 points respectively.

Energy Companies That Stand Out

Free Energy

Dallas, Texas-based Ambit Energy offers an opportunity for customers to earn free energy. The company provides electricity and natural gas services to nearly 1.2 million people in deregulated markets across the United States.

Ambit Energy gives out over one million dollars to their customers every month through their Free Energy program. Customers can reduce their monthly energy bills when they refer friends to become Ambit Customers. Depending on the number of customers referred, your bill could be reduced to taxes and fees only. Ambit applies the credit directly to your energy bill or mails out a check for as long as you maintain a minimum number of qualified referrals.
