In this work, I framed the Renyi and Tsallis Holographic Dark Energy (HDE) models within the presence of a spatially flat and isotropic FRW model filled with matter and dark energy in teleparallel gravity. The energy densities of Renyi HDE and Tsallis holographic dark energy (THDE) are increasing functions of z and validate the expanding conduct of the universe. It is worthwhile to note that for -1<z<0, the EoS parameter of Renyi HDE approaches to phantom region , while THDE confirms to Quintessence region. Further for 0<z, the EoS parameter of Renyi HDE slants to CDM model ,while THDE settles to Quintessence region. The model behaves like LCDM with the statefinder parameters having the values 1,0.
