Market Segmentation Overview
By Fuel Type
| Sub-Segment | Key Trend |
| Coal | Capacity payment mechanisms in China and India sustain revenue as utilisation falls; ultra-supercritical retrofits and flue gas desulphurisation dominate capital spend. |
| Gas | Advanced-class combined-cycle orders at a decade high; hydrogen-ready combustors becoming a standard procurement requirement |
| Nuclear | Life-extension and refurbishment spending replaces new-build as the primary revenue source across OECD fleets. |
| Others | Biomass co-firing, waste-to-energy and oil-fired peaking shaped by local fuel policy and waste management mandates |
Coal leads on installed base rather than momentum: Chinese and Indian regulators have deliberately restructured tariffs to pay coal units for availability, which keeps revenue intact even as capacity factors decline toward 45%. Gas is the fastest-growing sub-segment because buyers now specify build speed and ramp capability alongside efficiency, and advanced-class machines clear both bars while cutting carbon intensity roughly 60% against subcritical coal. Nuclear revenue is refurbishment-led, tied to licence renewal cycles rather than construction pipelines, and Others stays small and regionally fragmented.
