Abstract: I derive the Komar energy function for the S-dS black-hole solution in dRGT massive gravity by keeping the usual direction of the Time-like Killing vector. The Komar energy is modified due to the dynamics of the Stuckelberg fields which is stored in the spatial dependence of the gauge transformation function in unitary gauge. The modification of the notion of energy is the key point for understanding the predictable character of the theory.
