Power plant and method of use

A method for operating a power plant, comprising:

• compressing ambient air with at least one main air compressor to form a compressed ambient gas flow;
• delivering at least a first portion of the compressed ambient gas flow to at least one gas turbine assembly of a power plant comprising two or more gas turbine assemblies that are fluidly connected by an inter-train conduit, wherein the inter-train conduit further comprises an inter-train valve that is in a closed position and wherein a method for operating the at least one gas turbine assembly comprises:
• mixing the at least a first portion of the compressed ambient gas flow with at least a first portion of a recirculated low oxygen content gas flow and a fuel stream to form a combustible mixture and burning the mixture in a turbine combustor to produce the recirculated low oxygen content gas flow;
• driving a turbine, connected to a turbine shaft, using the recirculated low oxygen content gas flow;
• driving a turbine compressor, via the turbine shaft, which is fluidly connected to the turbine combustor;
• and
• recirculating at least a portion of the recirculated low oxygen content gas flow from the turbine to the turbine compressor using a recirculation loop.
