Electricity Generating Authority of Thailand

The Electricity Generating Authority of Thailand (การไฟฟ้าฝ่ายผลิตแห่งประเทศไทย), commonly known as EGAT, is a Thai state enterprise established in 1968 that generates, transmits, and sells electricity.

Electricity Generating Public Company Limited

Electricity Generating Public Company Limited, known as EGCO Group, is a Thai power holding company founded by EGAT in 1992 as Thailand's first independent power producer.

Electricity generation

Electricity generation, also called electric power generation, converts primary energy sources like coal, natural gas, nuclear, sunlight, and wind into electrical power for the grid.

Electricity Generation Company of Bangladesh

The Electricity Generation Company of Bangladesh (EGCB) is a state-owned power generation company under the Bangladesh Power Development Board, operating four plants with 1,032 MW capacity.

Electricity liberalization

Electricity liberalization is the reform of a state-owned or monopoly electric power sector to open generation and retail supply to competition, first enacted in Chile in 1982.

Electricity market

An electricity market is an organized system where generators, suppliers, traders, and consumers buy and sell electric power, with prices set by auctions, contracts, or regulated tariffs.

Electricity Market Design reform

The Electricity Market Design reform is the European Union's 2024 revision of its electricity market rules, adopted after the 2022 energy crisis to reduce consumer bills' dependence on fossil fuel prices.

Electricity meter

An electricity meter, also called a kilowatt-hour or energy meter, is a device that measures electrical energy consumed by a customer in kilowatt-hours for billing.

Electricity sector in Australia

The electricity sector in Australia centers on the National Electricity Market, launched in 1998, which serves the eastern and southern states and about 80% of national consumption.

Electricity sector in Canada

Canada's electricity sector generated 622.2 million MWh in 2024, over 60% from hydro, wind, and solar, with each province running its own system under its own jurisdiction.

Electricity sector in China

The electricity sector in China is the world's largest national power system, consuming 9.85 trillion kWh in 2024 and leading both wind and solar construction.

Electricity sector in India

The electricity sector in India, also called the Indian power sector, supplies the world's third-largest electricity market, with about 462,000 MW installed capacity and roughly 2,000 TWh generated annually.

Electricity sector in Mexico

The electricity sector in Mexico is led by the Federal Electricity Commission (CFE), which must supply at least 54 percent of the power after a 2025 reform reversed the 2013 liberalization.

Electricity sector in the European Union

The electricity sector in the European Union is a coupled internal power market in which member states keep their own energy mix, with renewables reaching half of consumption in 2025.

Electrified Powertrain Flight Demonstration

The Electrified Powertrain Flight Demonstration was a NASA program that flight-tested hybrid electric aircraft propulsion with GE Aerospace and magniX; GE's Saab 340B became the first hybrid electric aircraft to fly above 30,000 feet.

Electrify America

Electrify America is an American electric vehicle charging network created by Volkswagen Group to fulfill a $2 billion Clean Air Act settlement, with chargers up to 350 kW.

Electro-absorption modulated laser

An electro-absorption modulated laser (EML) combines a continuous-wave DFB laser and an electro-absorption modulator on a single indium phosphide chip, giving lower chirp and higher bandwidth than directly modulated lasers.

Electro-chemo-mechanical contact loss in all-solid-state cells

Electro-chemo-mechanical contact loss in all-solid-state cells is degradation in which electrode volume change during cycling breaks solid-solid contact, and the rigid solid electrolyte cannot re-wet the surface.

Electro-diesel locomotive

An electro-diesel locomotive, also called a dual-mode or bi-mode locomotive, draws power from overhead wires or a third rail, plus an onboard diesel engine for non-electrified lines.

Electro-diesel multiple unit

An electro-diesel multiple unit is a self-propelled train using both diesel and electric power to run on electrified and non-electrified track. The Southern Region of British Railways first used them in 1956.

Electro-Fenton process

The electro-Fenton process is an electrochemical advanced oxidation process for water treatment that generates hydrogen peroxide at a cathode, producing hydroxyl radicals that degrade persistent pollutants.

Electro-Motive Diesel

Electro-Motive Diesel, also known as EMD, is an American locomotive maker founded in 1922 that led the switch from steam to diesel and has been owned by Caterpillar's Progress Rail since 2010.

Electro-optic modulator

An electro-optic modulator (EOM) is a device that uses the Pockels effect to control light's phase, amplitude, polarization, or frequency with an applied voltage, often built from lithium niobate.

Electrocaloric multilayer coolers

Electrocaloric multilayer coolers are solid-state cooling devices that use stacks of thin ferroelectric or relaxor ceramic or polymer layers, driven by electric fields, to pump heat through the electrocaloric effect.

Electrocaloric polymer cooling

Electrocaloric polymer cooling is a solid-state refrigeration approach in which ferroelectric polymer films pump heat reversibly under an electric field, pursued as a refrigerant-free alternative to vapor compression.

Electrocatalyst degradation

Electrocatalyst degradation is the loss of catalyst activity or integrity in devices such as fuel cells and electrolyzers, caused by dissolution, ripening, agglomeration, and detachment.

Electrocatalytic hydrogenation of phenolic bio-oil compounds

Electrocatalytic hydrogenation of phenolic bio-oil compounds is an electrochemical method that upgrades lignin-derived phenols at a cathode, using hydrogen from water at ambient pressure and temperatures at or below 80 °C.

Electrochemical additive manufacturing

Electrochemical additive manufacturing (ECAM) is a family of non-thermal 3D printing techniques that builds metal structures by electrochemical deposition at room temperature, offering nanoscale resolution for microelectronics and sensing.
