Systems Involving Hybrid Power Plants

A system comprises a first heat recovery steam generator (HRSG) (102) having an upstream intake duct portion (101), a first gas turbine engine (106) connected to a first exhaust duct operative to output exhaust from the first gas turbine engine (106) to the upstream intake duct portion (101) of the first HRSG (102), and a second gas turbine engine (104) connected to a second exhaust duct operative to output exhaust from the second gas turbine engine (104) to the upstream intake duct portion (101)of the first HRSG (106).
