From table ES3 we can see that steam based plants are expensive in pure equipment costs. Which makes sense comparing a tiny gas turbine giving direct mechanical force. Then you can use the waste heat for steam generation if that makes sense in your location. Comparing this to coal and nuclear plants huge boiler and turbine setup with about the same output. Nuclear adding even more complexity of different loops and safety requirements. Haven't dug deeper into that report than the executive summary though.
