Inputs for the capital costs of modifications to process areas of the power block are entered on the Retrofit or Adjustment Factors parameter screen. See Retrofit or Adjustment Factor Inputs for an explanation of retrofit costs. The power block has the following capital cost process areas:

•Gas Turbine: The Gas Turbine retrofit factor is a ratio of the costs of retrofitting an existing facility versus a new facility, using the same equipment.

•Heat Recovery Steam Generator: The Heat Recovery Steam Generator retrofit factor is a ratio of the costs of retrofitting an existing facility versus a new facility, using the same equipment.

•Steam Turbine: The Steam Turbine retrofit factor is a ratio of the costs of retrofitting an existing facility versus a new facility, using the same equipment.

•HRSG Feedwater System: The Boiler Feedwater retrofit factor is a ratio of the costs of retrofitting an existing facility versus a new facility, using the same equipment.
