In general, the NETL reports provide excellent equipment cost and estimation values and concepts which are applied throughout the surface plant capital cost methodology. Despite the NETL reports being for different electricity generation technologies (i.e. coal and natural gas), the NETL reports provide a level of detail and transparency which is not available in GETEM. For instance, the NETL values for turbine cost are easily extended to an ORC, whereas the GETEM second-law regression of turbine cost is not useful to estimate the cost of a turbine. Thus, the cost estimation strategy of the NETL reports reflects much of the strategy adopted within genGEO.
