A system and a method to supply a coolant to a turbine bucket of a turbine. The system includes an extraction system configured to extract air from a main compressor airflow, a supply circuit, at least a part of which is disposed at an exterior of the gas turbine, coupled to the extraction system and configured to transport the extracted air, as an ingredient of the coolant, from the extraction system to a coolant insertion region, and a cooling system, disposed proximate to the coolant insertion region of the gas turbine and coupled to the supply circuit at a position on-board the gas turbine, the cooling system being configured to supply the turbine bucket with the coolant, including the extracted air.
