The premium propane that we sell is stored in our large bulk propane tanks before it is delivered to you.
Our bulk storage facilities are large enough to guarantee a steady supply of propane to our entire market area during even the coldest of winters.
Propane supply is maintained by PSI Propane with our combined 270,000 gallon storage tank capacity and rail car storage.
This ensures that only the highest grade, HD-5 propane is under our control from its origin at the refinery all the way to your tank.
