Power station

A power station, also called a power plant, is an industrial facility that generates electricity by driving a generator with a turbine turned by steam, water, or gas.

Power Station (recording studio)

Power Station, also Avatar Studios and now Power Station at Berklee NYC, is a historic Manhattan recording studio founded by Tony Bongiovi in 1977 in a former Con Edison power relay station, known for its live-sound acoustic design, TEC Awards, and clients from Springsteen to Lady Gaga.

Power steering

Power steering, also called power-assisted steering, is any system that reduces the effort of turning a vehicle's wheels. It evolved from 1950s hydraulic pumps to today's electric motors.

Power Stone 2

Power Stone 2 is Capcom's 2000 four-player 3D arena fighting game, sequel to Power Stone, released on NAOMI arcade and Sega Dreamcast (April 27, 2000 Japan), later PSP and Capcom Fighting Collection 2.

Power strip

A power strip is a block of electrical sockets on a cord that lets several devices run from one wall outlet, often with a circuit breaker or surge protection.

Power supply

A power supply, also known as an electronic power supply, is the unit converting AC mains electricity into the regulated DC rails computer components use, in ATX, SFX, or redundant server formats.

Power Supply Adjustor (Arizona)

The Power Supply Adjustor is a pass-through charge on Arizona Public Service electric bills that recovers fuel and purchased power costs, with rates reviewed yearly by the Arizona Corporation Commission.

Power supply unit (computer)

A power supply unit (PSU), also called a computer power supply, converts AC from a wall outlet into the regulated DC voltages, principally +3.3, +5, and +12 V, that a computer needs.

Power symbol

The power symbol, also known as the on off symbol, is the broken circle with a line (⏻) standardized in 1973 as IEC 60417-5009, officially meaning standby.

Power synchronization control

Power synchronization control is a grid-forming control method for voltage-source converters that synchronizes to the AC grid through a power loop instead of a phase-locked loop.

Power system stabilizer

A power system stabilizer (PSS) is a supplementary controller on a synchronous generator's excitation system that damps low-frequency electromechanical rotor oscillations by modulating field voltage, extending power transfer capability.

Power system state estimation

Power system state estimation is a computational method that estimates voltage magnitudes and phase angles at every bus of an electric network from redundant, noisy power and voltage measurements.

Power take-off

A power take-off (PTO) is a splined output shaft, usually at the rear of a tractor or truck gearbox, that transfers engine power to driven implements.

Power tool

A power tool is a machine driven by an energy source such as an electric motor, compressed air, or gasoline, used for work like drilling, cutting, and grinding.

Power transform

A power transform is a family of parametric data transformations built from powers of a variable that reshapes a distribution toward normality, constant variance, or linearity, including the Box–Cox transformation.

Power transformer

A power transformer transfers energy between AC circuits at different voltage levels, stepping voltage up for transmission and down for distribution in the power grid.

Power Trip (band)

Power Trip is a Dallas, Texas crossover thrash band formed in 2008, known for Manifest Decimation (2013) and Nightmare Logic (2017) on Southern Lord, a Grammy-nominated Executioner's Tax, vocalist Riley Gale's 2020 death, and a 2023 return with Seth Gilmore.

Power Up (ϟUP) (album)

Power Up (PWR/UP) is AC/DC's 17th studio album, released 13 November 2020 on Columbia Records; produced by Brendan O'Brien and credited entirely to Angus and Malcolm Young as a tribute to Malcolm, it peaked at number 1 on the UK Official Albums Chart.

Power Up Tour

Power Up Tour (PWR/UP Tour): AC/DC's stadium tour named for its 2020 album Power Up (#1 in 21 countries). Ran 2024 Europe, 2025 North America/Europe/Australia, 2026 South America and North America, ending at MetLife Stadium, October 2, 2026.

Power usage effectiveness

Power usage effectiveness (PUE) is a data center efficiency metric, defined in 2007 as total facility energy divided by IT equipment energy, with a theoretical floor of 1.0.

Power Windows (album)

Power Windows, Rush's eleventh studio album (October 1985), first produced with Peter Collins, recorded at The Manor, AIR Montserrat, and Sarm East; synth-heavy, power-themed lyrics, first Rush album released directly to CD, Billboard 200 #10.

Power Without Glory

Power Without Glory is a 1950 novel by Australian writer Frank Hardy tracing John West, a thinly disguised John Wren, from a Melbourne slum to political power through bribery and fear.

Power-associative algebra

A power-associative algebra is a not-necessarily-associative algebra in which powers of any single element are well defined, a concept introduced by A. A. Albert in his 1948 paper Power-Associative Rings.

Power-flow study

A power-flow study, or load-flow study, computes voltages, currents, and power flows in an electrical network, checking that delivery stays within voltage and thermal limits.

Power-from-shore

Power-from-shore is the supply of onshore grid electricity to offshore oil and gas installations via subsea cables, replacing gas turbines; it is Norway's most important measure for cutting petroleum emissions.

Power-knowledge

Power-knowledge (pouvoir-savoir) is Michel Foucault's thesis that power and knowledge directly imply one another, formulated in Discipline and Punish (1975); power is productive, not merely repressive, and the concept anchors genealogy, the Habermas debate, and applications from discourse analysis to algorithmic governance.

Power-law fluid

A power-law fluid, also called the Ostwald–de Waele model, is an idealized non-Newtonian fluid whose shear stress is proportional to a fixed power of the shear rate.

Power-line communication

Power-line communication, also known as power-line networking or broadband over powerline, carries data signals over existing electrical power lines for smart grids, smart metering, home automation, and in-home networking.

Power-on self-test

The power-on self-test (POST), also known as BIOS POST, is the series of internal hardware checks firmware runs at power-on, before the operating system loads.

Power-to-gas

Power-to-gas (PtG) is an energy conversion technology that uses electrolysis to turn electricity into hydrogen or synthetic methane, linking the power grid with the gas grid for seasonal storage of renewables.
