Company Information

Realgy, where energy is all about Price, Information, and Service.™

Realgy Energy Services was founded by individuals who worked for many years with large utilities, energy service companies, and energy marketers. Within these organizations they saw bureaucracy, the limitation of systems, software, and in some cases poor management that prevented individuals from doing their job. They were determined to be different, and still are.
