IGCC vs Cogen

The viability of IGCC primarily depends on the difference of cost between IGCC Feed Fuel (in our case, Petcoke) and the Natural Gas. As can be seen, the cogeneration (GTG + HRSG) can be part of the overall IGCC scheme.

If the different of cost between IGCC Feed Fule and NG is not attractive and the capex of IGCC is very high, one could proceed with cogen first. This could be considered as 1st phase of the project. However, the cogen viability will depend on the difference of cost between self generation of power/steam vs buying power/steam from utility company. A thorough techno-economic assessment needs to be done prior to deciding IGCC, Cogen or maintain status quo.
