Thermopower waves
Thermopower waves are a direct energy conversion method in which a self-propagating reaction wave along a carbon nanotube turns exothermic fuel into electricity, first demonstrated at MIT in 2010.
Thi Vai LNG Terminal
Thi Vai LNG Terminal (Vietnamese: Kho cảng LNG Thị Vải) is Vietnam's first LNG import terminal, in Ba Ria–Vung Tau province, inaugurated in 2023 with 1 million tonnes annual capacity.
Thin stillage
Thin stillage is the liquid coproduct of grain ethanol production, separated from whole stillage by centrifugation after distillation; most is recycled as process water or evaporated into feed.
Thin-film gallium arsenide solar cell
A thin-film gallium arsenide solar cell is a lightweight, flexible photovoltaic device whose GaAs absorber is peeled from its growth wafer, mainly for space and drones.
Thin-film solar cell
A thin-film solar cell is a photovoltaic cell made by depositing thin semiconductor layers on glass, plastic, or metal rather than a silicon wafer, using far less material.
Thio-LISICON
Thio-LISICON (thio-lithium superionic conductor) is a family of crystalline sulfide solid electrolytes for lithium batteries, introduced by Ryoji Kanno and coworkers in 2000 as the first crystalline sulfide electrolytes.
Third Energy Package
The Third Energy Package is a set of five EU legislative acts adopted in 2009 that reorganized the internal market for electricity and natural gas.
Third harmonic injection
Third harmonic injection is a modulation technique for three-phase inverters that raises the maximum modulation index from 1 to 1.155 per unit, improving DC-link utilization.
Thomas Hill Energy Center
The Thomas Hill Energy Center is a coal-fired power station in Clifton Hill, Missouri, owned by Associated Electric Cooperative, with three units built between 1966 and 1982.
Thorium fuel cycle
The thorium fuel cycle is a nuclear fuel cycle that breeds fissile uranium-233 from abundant fertile thorium-232, proposed as an alternative to the uranium–plutonium cycle but never commercialized.
Thorium molten-salt reactor (China)
China's 2 MWt thorium molten-salt reactor program, led by the Shanghai Institute of Applied Physics, operates TMSR-LF1 at Wuwei, Gansu, first to convert thorium to uranium.
Thorium-based nuclear power
Thorium-based nuclear power uses fertile thorium-232 as the principal fuel, converting it into fissile uranium-233 through neutron irradiation; it works in light water and molten salt reactors.
THORP
THORP, the Thermal Oxide Reprocessing Plant at Sellafield in West Cumbria, England, reprocessed 9,000 tonnes of spent oxide fuel from 1994 to 2018, earning about £9 billion, and now stores spent AGR fuel.
Three Mile Island accident
The Three Mile Island accident was a partial nuclear meltdown at a Pennsylvania power plant on March 28, 1979, the worst in U.S. commercial nuclear power history.
Three Mile Island Nuclear Generating Station
Three Mile Island Nuclear Generating Station is a two-unit nuclear power plant on Three Mile Island in the Susquehanna River near Harrisburg, Pennsylvania, site of the 1979 partial nuclear meltdown.
Three Mile Island Unit 1
Three Mile Island Unit 1, also known as TMI-1, is a Pennsylvania nuclear reactor that ran from 1974 to 2019 and is being restarted for Microsoft.
Three-Day Week
The Three-Day Week was a UK emergency measure limiting commercial and industrial electricity users to three specified days a week, effective 31 December 1973 to early March 1974.
Three-level neutral-point-clamped inverter
The three-level neutral-point-clamped (NPC) inverter, introduced by Nabae, Takahashi, and Akagi in Japan in 1981, connects each output phase to the positive rail, negative rail, or neutral point.
Three-phase electric power
Three-phase electric power is alternating current carried on three conductors with voltages shifted 120 degrees, delivering constant power and needing no return conductor for balanced loads.
Three-phase inverter
A three-phase inverter is a power-electronic converter that converts DC input into three-phase AC output, used for industrial motor drives, solar and wind generation, and battery storage.
Three-phase transformer
A three-phase transformer changes the voltage of three-phase alternating current, built as one unit on a shared core or as a bank of three single-phase transformers.
Three-winding transformer
A three-winding transformer is a power transformer with primary, secondary, and tertiary windings per phase, connecting three voltage levels or supplying station auxiliaries and voltage control.
Thumper (cable fault testing)
A thumper is a high-voltage surge generator that locates faults in underground power cables by arcing at the fault, producing an audible thump crews pinpoint from the surface.
Thunderhead Wind Energy
Thunderhead Wind Energy is a 300-megawatt onshore wind farm with 108 turbines in Antelope, Holt, and Wheeler Counties in northeastern Nebraska, commercially operational since 2022 and developed by Invenergy.
Thungela Resources
Thungela Resources Limited, known as Thungela, is a South African thermal coal producer created in 2021 from Anglo American's coal operations, listed on the JSE and London Stock Exchange.
Thyristor valve
A thyristor valve is the complete engineered assembly of series-connected thyristors with gating, grading, and cooling that performs one switching function in an HVDC converter station.
Thyristor-controlled reactor
A thyristor-controlled reactor (TCR) is a shunt inductor in series with back-to-back thyristors, whose current is varied continuously and forms the core of most static var compensators.
Thyristor-controlled series capacitor
A thyristor-controlled series capacitor (TCSC) is a series-connected FACTS device that varies the reactance of an AC transmission line, used for power flow control, damping power oscillations, and mitigating subsynchronous resonance.
Thyristor-switched capacitor
A thyristor-switched capacitor (TSC) is a shunt capacitor bank switched fully on or off by a bidirectional thyristor valve, giving fast, near-transient-free reactive power control in static var compensators.
Tía Juana Oil Field
The Tía Juana oil field is a large, mature heavy-oil field on the northeast shore of Lake Maracaibo, Venezuela, discovered in 1928 and part of the Bolivar Coastal Field.
