Dispersion relation for plasma waves in graphene bilayer has been investigated. Influence of the bias voltage on the dispersion curve for plasmon in bigraphene has been studied within random phase approximation. The possibility of controlling of energy and group velocity for plasmon by changing of bias voltage has been shown. The dependence of plasmon energy on the bias voltage has been predicted to have the nonmonotonous character. Effect of the temperature on the plasmon dispersion has been analyzed.
