- We consider the broadband spectral energy distribution of the high energy peaked (HBL) blazar Mkn 501 using $\textit{Swift}$-XRT/UVOT, NuSTAR and $\textit{Fermi}$-LAT observations taken between 2013 and 2022. The spectra were fitted with a one-zone leptonic model using synchrotron and synchrotron self-Compton emission from different particle energy distributions such as a broken power-law, log-parabola, as well as distributions expected when the diffusion or the acceleration time scale are energy dependent. The jet power estimated for a broken power-law distribution was $ \sim 10^{47} (10^{44})$ erg s$^{-1}$ for a minimum electron energy $γ_\text{min} \sim 10 (10^3)$. However, for electron energy distributions with intrinsic curvature (such as the log-parabola form), the jet power is significantly lower at a few times $ 10^{42}$ erg s$^{-1}$ which is a few percent of the Eddington luminosity of a $10^7$ M$_\odot$ black hole, suggesting that the jet may be powered by accretion processes. We discuss the implications of these results.
