  The normalization of the gluon condensate and of renormalon-related power
corrections in QCD is computed under the assumption that their ``perturbative''
part dominates over any eventual extra contribution from the non-trivial
vacuum. The calculation is performed in the infrared finite coupling framework,
assuming an infrared fixed point is present in the perturbative coupling down
to low values of N_f. The freezing perturbative coupling is reconstructed using
a Banks-Zaks expansion approach. Parameter-free predictions of the low energy
moments of the coupling, which determine the process-independent part of the
power corrections, are obtained for a number of choices of the running
coupling.
