Interest in natural gas technologies is being driven by twin goals of increasing energy efficiency and reducing power plant emissions, including CO2. The prospect of shale gas deposits coming online and lowering fuel costs is an added consideration in favor of constructing new gas-steam systems. An important factor affecting profitability is the choice of the power output capacity of the planned units, which naturally impacts initial capital costs. If it is impossible to introduce new units into the power generation system, it is important that the economic analysis should take account of the costs related to early decommissioning of power units. This paper presents an analysis of two gas-steam systems with different power output capacities. The minimum selling prices of electricity are determined. For decommissioned power plants, the conditions (i.e. electricity costs) which make investments in new gas-steam systems equally profitable are defined.
