A method to pre-heat gas at gas Pressure Reducing Stations. A first step involve providing at least one electrical line heater having a flow path for passage of natural gas through electrical heating elements. A second step involves passing the high pressure cold natural gas stream along electrical heating elements and heating it up before de-pressurization. A third step involves the expansion of the high pressure heated gas in a enclosed vessel that houses a gas expander and power generator. The expansion of the gas generates shaft work which is converted into electrical power by the power generator and the expanded low pressure gas cools the power generator. This process results in the recovery of energy to replace the slipstream of natural that is presently used to pre-heat gas at Pressure Reduction Stations.
