The TVV-800-2EU3 is a three-phase synchronous turbo generator rated at 830 MW active power class — utility-scale generation equipment for thermal and nuclear power plants. The machine operates at 24 kV with a stator current of 22,185 A and a conversion efficiency of 98.8%, a figure that defines its economics: at this power level, each tenth of a percent of efficiency represents significant fuel cost over the unit's service life.
The build is correspondingly monumental — 552 tonnes total, with a 342-tonne stator and an 84-tonne rotor. Turbo generators of this class are the heart of national energy infrastructure, purchased through project contracts that include engineering coordination, transport logistics, installation supervision and commissioning.
The TVV series represents the Russian heavy electrical engineering school, with an installed base across decades of power plant construction worldwide. The unit targets power utilities, EPC contractors and plant modernization programs, with all terms defined contractually.
