A power plant is a facility that generates electricity on a large scale, providing power to homes, schools, businesses, and entire cities. Most power plants work by spinning massive generators: coils of wire rotate inside powerful magnets, creating electrical current that flows through power lines to wherever it's needed.

Different types of power plants use different energy sources to spin those generators. Coal and natural gas power plants burn fuel to boil water into steam, which turns giant turbines connected to generators. Nuclear power plants split atoms to create heat, also making steam to spin turbines. Hydroelectric plants use flowing water from dams to turn turbines directly. Wind farms have turbines with enormous blades that catch the wind, while solar power plants convert sunlight directly into electricity using special panels.

The word plant here doesn't mean something that grows. It means a factory or industrial facility. You might also hear about manufacturing plants (where goods are made) or water treatment plants (where water is cleaned). A power plant is simply the place where electrical power is produced, often running continuously day and night to keep the lights on across an entire region.
