power grids
National energy arteries
Power grids are networks that deliver electricity from generators to consumers across large areas.
The grid includes power plants, transmission lines, substations, and distribution systems working together.
The power grid failed during the heat wave.
Grid stability requires constant balancing of supply and demand—too much or too little electricity causes blackouts.
Most countries operate interconnected regional grids rather than one national system.
