 Lenin biographers have often characterised the introduction of the NEP as one of his most significant achievements and some believe that had it not been implemented then Sovnarkom would have been quickly overthrown by popular uprisings.In January 1920, the government brought in universal labour conscription, ensuring that all citizens aged between 16 and 50 had to work.Lenin also called for a mass electrification project, the GOELRO plan, which began in February 1920; Lenin's declaration that "communism is Soviet power plus the electrification of the whole country" was widely cited in later years.
