Abstract: We consider the production of excited electrons with spin-1/2 at the future SPPC-based electron-proton colliders with center-of-mass energies of $8.4$, $11.6$, $26.6$ and $36.8$ TeV. These exotic particles are predicted in the composite models. We calculate the production cross-sections and concentrate on the photon decay channel of the excited electrons with the process of $ep\rightarrow e^{\star}X\rightarrow eγX$ . The pseudorapidity and transverse momentum distributions of the electrons and photons in the final-state have been plotted in order to determine the kinematical cuts best suited for discovery of the excited electrons. By applying these cuts we compute $2σ$, $3σ$ and $5σ$ contour plots of the statistical significance of the expected signal in the parameter space ($L$, $m^{\star}$), where $L$ denotes the integrated luminosity of the collider and $m^{\star}$ is the mass of the composite electrons.
