Figure shows the cooling tower specific costs compared in this analysis. All costs are shown for tower standard design conditions of a 15°C ambient temperature, a 7°C approach temperature, and a 4°C temperature range. The single 'BAC' data point is the specific cost of the 1 MW th reference unit. The forty-five cooling towers for natural gas and coal plants from NETL (2007-2019b) are also shown. Pidaparti et al. (2015) reports several vendor quotes for an open wet cooling tower from Delta Cooling Towers. Additionally, the four binary cooling tower cost data points shown result from complete GETEM simulations with geofluid (GF) production temperatures between 125°C and 200°C.
