Comparative list of electrical power[]

Milliwatt = 0.001 watts
Deciwatt = 0.1 watts

B'Elanna Torres wanted to siphon every last deciwatt of energy from the plasma network to the deflector. (VOY: "Fair Haven")


The value exceeds would be 17 orders of magnitude above the yattawatt.

Megawatt = 1 million watts
Gigawatt = 1 billion watts

Montgomery Scott was sure he could get a few extra gigawatts out of the shields of the USS Jenolan to support his plan to use the ship to prop open the doors of a Dyson sphere. (TNG: "Relics")

Captain Kathryn Janeway reroute every spare gigawatt to USS Voyager's shields to protect the ship from the resulting explosion caused when they fired at a metreon gas cloud. (VOY: "Think Tank")

Terawatt = 1 trillion watts

In 2365, the command headquarters of Daled IV utilized a communication system that originated from a terawatt source, which was necessary to penetrate the planet's atmosphere. According to Commander William T. Riker, "that's more power than our entire ship could generate," meaning that they lacked the ability to respond to the communique. (TNG: "The Dauphin")

By 2368, the USS Enterprise-D was stated as having a powerful matter/antimatter warp reaction system that had an output that was normally capable of kicking plasma up into the terawatt range. (TNG: "The Masterpiece Society")

In 2374, the Entharan weapons dealer Kovin introduced Tom Paris and Seven of Nine to a terawatt powered particle beam rifle. (VOY: "Retrospect")
