8. Economic aspects
The investment cost of a power plant depends on a very large number of parameters linked to the fuel, the desired performance, the processes chosen, the technical options selected, the site, the regulations, etc. A detailed study taking into account all these parameters is necessary to know the exact investment cost for a given power plant. A detailed study that takes all parameters into account is required to determine the exact investment cost for a given plant.
These investment costs are likely to come down in the future through savings on engineering and construction, and by taking advantage of the scale factor when building more powerful units.
Significant savings appear to be difficult to achieve in the short term on the construction of units in contact with syngas, mainly due to the use of elaborate, and therefore expensive, materials....

Bibliography
Manufacturers (non-exhaustive list)
The construction of an IGCC plant generally involves three manufacturers, one for each of the main islands: gasifier, combined cycle and air separation unit. Tables 1 ,
Operators
Table 4 shows the main operators of industrial-scale IGCC power plants in operation or under construction worldwide. This list is likely to grow in the near future, as all utilities are likely to equip themselves with IGCC plants, since this is one of the clean coal technologies....
