According to the project, the installed generating capacity was 560 megawatts, the length of a convex dam was 760 m, the width was 56 m, the height was 60 m. Eight water turbines and five generators were designed and manufactured in the United States, other three generators were made at the Leningrad factory "Electrosila".
