In industrial and institutional steam systems, backpressure turbine generators can produce electricity with no added fuel, and often produce electricity with well in excess of 100% fuel efficiency. This occurs because these systems reject hot condensate to the sewer. A result, the net impact of utilizing additional enthalpy (A thermodynamic function of a system, equivalent to the sum of the internal energy of the system plus the product of its volume multiplied by the pressure exerted on it by its surroundings) from the steam in a backpressure turbine generator is simply to lower the temperature of rejected condensate - making the resulting electricity fuel-free.

Implications: Steam users served by most district steam systems can extract some of the presently wasted enthalpy and produce fuel-free electricity. In the past, analysis of these systems has assumed the enthalpy that is removed would need to be made up by purchasing added steam, but this is not ( in most cases) necessary. These installations produce no added pollution, either of regulated pollutants or carbon dioxide, thereby presenting a compelling argument to those who believe that the environment is the enemy of the economy. Every backpressure turbine/generator installation represents a pollution control device with a positive rate of return.

Free Electricity From
Backpressure Turbines:
The marginal cost of electricity generated by any power generation technology, independent of capital cost recovery and operations and maintenance is simply the cost of fuel divided by the power generation efficiency. Thermodynamics tells us that efficiencies are always less than 100% (e.g. you never get as much useful energy out as you put in), leading us to conclude that the only way to get free electricity is to find free fuel. However, because fuel usually has a cost, it becomes economically imperative to use a generator with the highest possible generation efficiency. When installed into existing steam systems, backpressure turbine/generators are the most efficient form of power generation ever invented.
