At present new electron and positron injection complex at BINP is commissioned and ready to feed VEPP-2000 collider with intensive beams with energy of 450 MeV. To obtain peak luminosity limited only by beam-beam effects in whole energy range of 160-1000 MeV and to perform high average luminosity with small dead time the top-up injection is needed. Booster BEP upgrade to 1 GeV includes modification of all magnetic elements, including warm dipoles magnetic field increase up to 2.6 T, vacuum chamber, RF-system, injection-extraction system. BEP comissioning is scheduled to the end of 2014.
