It is difficult to compare cooling tower costs when they all have different design conditions, which affect their cost. For instance, the GETEM cooling tower costs assume a 15°C ambient temperature, a 7°C approach temperature, and a 4°C range, while the NETL (2007-2019b) costs assume an 11°C ambient temperature, 5°C approach temperature, and 11°C range. It is not possible to directly compare these units without first correcting each to the same design conditions. Thus, we created the 'Design Correction Factor', , in Equation S35.
