Turbo-compressor/generator trains including high pressure ratio compressors with multiple intercooling and related methods are provided. A high pressure ratio compressor with multiple intercooling includes a casing with plural chambers, one or more shafts penetrating inside the chambers, and impellers mounted on the one or more shafts inside the chambers, respectively. Each chamber has a gas inlet and a gas outlet to allow gas flow to be input into and to be output from the respective chamber. A gas flow is successively compressed in each of the chambers, and is cooled outside the compressor when transferring from one chamber to a next chamber among the plural chambers.
