Abstract: A power generating unit includes a gas turbine with an air intake section, a compressor and at least one combustor and at least one turbine The power generating unit further includes a gas-cooled generator, being driven by the gas turbine and having a generator cooling system including at least one cooler, through which cooling water flows, and which removes heat from the generator. A more flexible operation of the unit can be achieved by connecting the generator cooling system to an air intake heat exchanger arranged within the air intake section of the gas turbine in order to transfer heat from the cooling water flowing through the generator cooling system, to the air flowing through the air intake section.
