JTAG power consumption

I am using a MAXII EPM240T100I5N device and I want to determine what the power consumption of the device is when it is running in JTAG (boundary-scan) mode when the device is running without any conf...

the maximum current that each JTAG output can supply

I presume, you mean IO pins configured as output.

IO pins have no current limiting function and you shouldn't short or overload them without risking to damage the chip. A maximum current of 25 mA has to be kept according to the datasheet. When shorted, a pin can sink or source up to 60 mA, which isn't permitted as continuous current.
