Company History & Timeline

From humble beginnings over 95 years ago as a local Northern New Jersey oil distributor to one of the premier full service energy providers along the eastern seaboard, Supreme Energy, Inc. prides itself in serving you, the customer, with all your energy needs.

1920s – 1970s


Company Established by William Mitchell Rile; Originally called the Mitchell Oil Company. Coal was the first product to be sold by Mitchell.


Tenneco Inc. purchases Mitchell Oil Company and merges it with one of Tenneco’s other oil companies, Supreme Fuel Company of Orange, NJ. Now operating as one company, the “Mitchell-Supreme Fuel Company” name is launched.

I had my central AC tune-up scheduled for May 12th. I received a call to let me know the technician was on the way. The tech actually arrived on time!! He was extremely professional and I was provided a detailed review of my central air conditioning unit. I’ve been a Supreme Energy customer since 2013 and highly recommend their services!!

Supreme Energy’s representatives took the time to understand my business and developed a customized energy solution to meet my specific needs.

Andrea D’Elia, Purchasing Manager, Dejana Truck & Utility Equipment

Your staff was expeditious in addressing my problems. I really needed assistance and the service department was attentive and professional. I have been a customer for well over 10 years and the team is the reason I remain a Supreme customer.

Thank you Mike, the salesperson, and the service technicians who put in a boiler at my house. The Plumbing inspector from the borough examined it and said the quality of work was exceptional. Many companies skimp on the materials and overall quality, but this was a job well done. Thank you Supreme!
