  The European Spallation Source linear proton accelerator will have a uniquely
high power of 5 MW. The modifications and additions to the accelerator that are
required to enable the generation of a uniquely intense neutrino Super Beam
ESS{\nu}SB for measurement of leptonic CP violation using a large water
Cherenkov detector are described. ESSnuSB is complementary to the other two
proposed Super Beam experiments Hyper-K and DUNE by the fact that the resulting
high neutrino beam intensity allows to place the neutrino detector at the
second oscillation maximum. The simulated performance of the ESS{\nu}SB
experiment is compared to the other two experiments under the assumption of the
same systematic errors in all three experiments. The performance of ESS{\nu}SB
for CP violation precision measurements is found to be highly competitive.
