•Radial and tangential eccentricities influence the performance of the TES system.•The optimization is more sensitive to the tangential than the radial eccentricity.•The optimum eccentric TES charges 7.1 times faster than the concentric case.•The optimum eccentric TES discharges 3 times slower than...
