1. An integration system for extracting power from an auxiliary energy source (AES), the integration system comprising:
a flue flow source configured to supply a flue flow having flue flow thermal energy to a first heat exchanger, the first heat exchanger being configured to extract flue flow thermal energy from the flue flow and to supply the flue flow thermal energy to a first flow;
a first splitter configured to split the first flow into a first turbine flow and a second turbine flow;
a first turbine coupled to receive the first turbine flow exiting the first splitter;
a second turbine coupled to receive the second turbine flow exiting the first splitter;
the auxiliary energy source (AES) configured to selectively supply auxiliary thermal energy to a supplemental heat exchanger disposed between the first splitter and the first turbine; and
a controller coupled to the flue flow source and the AES, the controller configured to:
determine whether the AES is supplying auxiliary thermal energy to the supplemental heat exchanger; and
when the AES is supplying auxiliary thermal energy to the supplemental heat exchanger, cause the first turbine to extract power from the first flow including both the extracted flue flow thermal energy and the auxiliary thermal energy.
