Propane back-up systems have over 70 years of proven technology and over 7,000 installations. They provide major energy cost savings and ensure supply during interruptions by allowing facilities to monitor two fuel sources. Considerations for a propane back-up system include simple paybacks of 2-4 years for equipment costing $90,000-$150,000. Applications include facilities distant from natural gas infrastructure like foundries, schools, and hospitals. Propane systems have low environmental impact from above or below ground storage without title issues like fuel oil. Utility Partners provides turnkey installation, training, and performance-based energy consulting for propane back-up systems.
