Power plant

A power plant is a ground-based facility built to provide cheap and reliable energy to a city or even region.

Earth's power plants were based on nuclear fission up until the 22nd century, when they were replaced with more efficient fusion plants. 

The power plants on Cardassia Prime were sabotaged during the final battle of the Dominion War, playing a critical part in the battle's outcome. 

A planet in the Delta Quadrant had polaric ion power plants, the use of which were protested by Pe'Nar Makull and Ny Terla. 

In the late 2370s, the planet Quarra in the Delta Quadrant suffered from a labor shortage in its industrial power plants due to the low level of automation in Quarren technology. As a result, the Quarren military began a secret program of commandeering passing alien starships, erasing their crews' memories, and putting them to work.
