We make use of publicly available results from N-body Millennium Simulation to create mock samples of lensed supernovae Type Ia and core-collapse. Simulating galaxy-galaxy lensing we derive the rates of lensed supernovae and find that at redshifts higher than 0.5 about 0.06percent of supernovae will be lensed by a factor of 2 or more. Future wide-field surveys like Gaia or Large Synoptic Survey Telescope (LSST) should be able to detect lensed supernovae in their unbiased sky monitoring. Gaia (from 2013) will detect at least 2 cases, whereas LSST (from 2018) will see more than 500 a year. Large number of future lensed supernovae will allow us to verify results of cosmological simulations. The strong galaxy-galaxy lensing gives an opportunity to reach high-redshift supernovae Type Ia and extend the Hubble diagram sample.
