E = hc / λ

Where

h = Planck Constant = 6.62606876 x 10-34 Js

c = Speed of light = 299792458 m/s

λ = Wavelength

The wavelenght can't possibly be smaller than Planck Length (1.6160 x 10-35 m) yields:

Maximun Energy = 12292360398.7464 J

Maximun Energy = 7.6722887211823E+28 ev

Is this valid? Is there a limit on how much energy an photon can carry? I've never heard of that...
