Power Generation System: Systems for generating electricity. Toshiba meets market needs worldwide with a comprehensive range of power generation systems, including nuclear, thermal, hydroelectric, geothermal, photovoltaic, wind power generation systems and fuel cells.

ABWR: Advanced Boiling Water Reactor. See BWR.

BTG: Boiler, Turbine and Generator. Key components used in power generation systems. Toshiba manufactures steam turbines and generators.

BWR: Boiling Water Reactor. A type of reactor for a nuclear power generation system, initially developed in the U.S. by the General Electric Company. In a BWR plant, the reactor uses low-enriched uranium as a fuel to bring the moderator and coolant water to the boil directly at the reactor core. The resulting steam drives the turbine.

CCS: Carbon Capture and Storage. CO2 separation and capture is an integral part of any CCS system. Toshiba has developed an amine solvent that consumes minimal energy during CO2 separation and capture, and has confirmed on a bench-scale test that it matches industry leading standards.

Combined Cycle Thermal Power Generation: Combined cycle systems combine gas and steam turbines to generate electricity in two stages. In the first stage, a gas turbine produces exhaust steam that drives the second stage steam turbine, which generates more electricity. The system is more efficient and releases less CO2 into the environment than conventional thermal power systems.

Nuclear reactor: A system that uses a controlled nuclear reaction to heat steam that is used to drive a turbine and generator to produce electricity.

Renewable Energy system: A power generation system based on a renewable energy source. Toshiba's renewable energy systems include hydroelectic, photovoltaic, geothermal and wind power generation systems.

Steam Turbine Generator: A key component of power generation systems. Toshiba has secured the No. 1 market share in the North American market for eight consecutive years (as of 2010).

VPP: Virtual Power Plant. A cloud-based distributed power plant that aggregates the capacities of heterogeneous distributed energy resources for the purposes of enhancing power generation, as well as trading or selling power on the electricity market. Toshiba is developing VPP business with a view to "Ancillary" market which is necessary when introducing a large amount of renewable energy.

4S: Toshiba's next generation nuclear reactor. 4S stand for Super-Safe, Small and Simple. The 4S is a sodium-cooled fast reactor with a thermal rating of 30MWt or 135MWt.
