Plasma
Plasma is one of the four fundamental states of matter. To be more exact, plasma is an ionized gaseous state, which is commonly seen in an electrical arc. Plasma was the main energy medium used to channel  to systems via EPS conduits in almost all starships. A plasma relay technician was responsible for rerouting plasma to systems to which they were not allocated. ()

In physics, studies of plasma included plasma dynamics and plasma physics. () Individuals who specialized in these fields, and more, included plasma specialists and EPS control specialists. (; )

History and use 
In 2032, John Kelly's Ares IV command module was equipped with an ion distributor, a primitive form of an EPS conduit, which could be adapted for use with the warp plasma from the . ()

Typically, warp drive-capable civilizations used super-energized electro-plasma in their power transfer systems, EPS for short. The electro-plasma was used as warp plasma for the engines and was also converted into standard electrical energy when fed off an EPS tap. Federation EPSes were designed around matter-antimatter reaction assemblies (usually warp cores) or fusion reactors (sometimes the impulse reactors). Besides the large warp plasma conduits, there were smaller plasma conduits, with EPS couplings that transferred power as electricity to all subsystems connected to the power transfer grid. If a plasma conduit or EPS tap ruptured, the contents could set off a plasma fire. (; )

In 2151,  was hit in the port nacelle by an unidentified alien vessel and lost drive plasma. ()

Aboard the  , in the Engineering Systems Database, there was a folder named "High Energy Plasma Constriction". This folder contained technical manuals relevant to the topic. (, okudagram)

In 2368, the crew of the Enterprise-D managed to turn dust particles in the atmosphere of Penthara IV into plasma by means of a phaser beam and electrostatic energy. ()

Aboard Deep Space 9, plasma was transported through the power conduits. In 2369, Ensign Aquino detected an irregularity in the plasma flow and investigated it. ()

Storage 

Plasma could be stored in warp plasma canisters or plasma infusers for mobile use, and was used in plasma torches and plasma weapons (such as plasma charges, plasma waves, plasma rifles, and plasma torpedoes). It could also be found naturally occurring, such as the energetic anomalies found in plasma storms and plasma fields. The Badlands were one such example of both anomalies. ()

Accidents 
Plasma could also pose a threat, such as in the form of a plasma surge.

In 2369, a plasma surge caused a fire in corridor H-12-A of the habitat ring aboard Deep Space 9. In this corridor, no fire suppression system was working. ()

The Ferengi Doctor Reyga was thought to be the victim of a plasma surge from an apparent suicide in a science lab aboard the Enterprise-D in 2369. ()
