Power Systems

Without power, nothing on a starship can function. The ship can’t move, life support cuts off, and the lights dim.  Therefore, Starfleet design engineers have taken pains to make sure that ships have multiple power source and energy to draw upon, the primary ones being the warp drive and impulse engines.

Warp Engines

By annihilating matter and antimatter, Federation vessels use the high energy electro-plasma forms generated by this reaction to power their vessels, and serves as a primary energy source particularly for space vessels, large starbases and the like. The Federation, or at least one of it’s primary races in particular, Terrans (Humans) have been using antimatter in some form for close to four centuries. Other races, such as the Vulcan’s, have used such power sources for far longer than Earth and were the first member world to introduce deuterium based antimatter as a fuel source, while others have used different variable methods of generating power that usually simulates matter/antimatter reactions in some form, or, was generally finally reached by all Federation members to the be the most efficient per cost and safety for energy productions as opposed to other means of power generation developed by Federation member worlds. The latest warp core technologies include casings made of Tetraburnium para-metallic poly-alloys, as well as other para metallic alloys commonly employed in new starship development, including tetrakellinide and poly-deutonic alloys. The most common form of antimatter annihilation technology fuel is deuterium, utilized by Starfleet and simple proton reactors for many civillians in backwater regions of the Federation. Tritium, while a powerful substitute for deuterium, is hard to synthesize in both matter and anti-matter, and only recently have tritium antimatter particles been created with the introduction of paralithium crystal technology pioneered in tetryon-plasma warp technology.

Tritium Antimatter Reactors

Other developments include tritium induced Matter/Antimatter Annihilation reactors utilizing enriched neutronic tritium isotope fuel with the equivalent anti-tritium, used in certain types of advanced starbases and other facilities, increasing power output as much as 200%. The Ascendant-class, and several other smaller classes of vessels, have been selected to receive tritium antimatter reactor upgrades projected within the next year.

Impulse Engines

Using advanced, stringed together, large variable sized and types of Deuterium Fusion reactors as a secondary power source for space vehicles, as well as the most commonly used source of power for all Federation member worlds due to the extreme nature of antimatter (if used on a planetary surface for example.). Some planetary-based Fusion reactors, as well as some used by Federation large outposts and starbases use a fusion/antimatter controlled reaction to generate power, similar to a warp core but only producing a 33% of a proportional warp cores M/ARA power output.

 Auxiliary Power

In addition to the Fusion reactors, which form the impulse engines, most ships, facilities, outposts, carry another set of reactors simply to generate power. Most have at least one additional fusion reactor and hold it in reserve in emergency or crisis situations rather than use it all the time.

Emergency Power

In addition to auxiliary power, ships and facilities have a small reserve of emergency power for use in crisis situations or when other power systems are nonfunctional. The emergency power system used a set of fusion reactors, which are independent from the standard and auxiliary power systems.

Individual Systems Power Generators

Some of the systems on a ship and/or facility have their own small ‘reserve’ of power for use in emergencies or when all other power systems are not working. Emergency life support has its own power systems, for example, and the ship’s phasers have phaser array power cells good for a few shots when there is no other power available. Whether this power can be siphoned for other uses is addressed under the respective systems. Even when it can be drained this way, it only provides a one-time power boost, not an ongoing supply.

Tritium Fusion Reactors

But using tritium isotopes that produce low-level subspace radioactive properties, fusion reactor efficiency can be increased by at least 25%. This method, albeit not a new innovation as it has been used, by other races as well, the Klingons for decades, is an uncommon practice in the Federation, but not unheard of. Research is further being applied to make tritium intermix fusion reaction matrix a viable alternative to standard and older deuterium-fusion reactors employed in Starfleet, and among other Federation member world space vehicle fleets.

(Tritium Fusion reactors replacing any fusion-based power system on a starship add x.25 power to the fusion reactors; Impulse engines, auxiliary fusion reactors, emergency power, and adds a +50 bonus to a ships shield grid as the tritium intermix is fed directly into the EPS manifolds.)

Ion Engines

Some advanced civilizations; such as the Eymorg under the influence of the Teacher; the Dominion; the Hydrans, use a form of propulsion and power generation known as ion propulsion. Ion propulsion provides greater speed and more power than comparative Starfleet engines. Thus far, Starfleet has only examined the Alpha-Ion drives equipped on Jem’Hadar Fighters/Attack ships and have only created basic working models for use on small vessels (size 4 and below).

(Ion engines can only be used on small vessels of size 4 and below in Starfleet, and require nacelles and PIS systems to function Nacelles function according to the listed speeds below, despite their original rated speeds. See below table.)

Electro-Plasma System

Power from the warp engine, impulse engines, and other sources is routed throughout a ship/facility by the electro-plasma system (EPS). The EPS is a network of microwave power transmission wave-guides. A ship’s EPS is assumed to be able to handle the power flow to run all systems at up to maximum efficiency without difficulty. But, when there’s a need to transfer more power—for example, to increase the damage a phaser does, boost shield strength, or feed more power to the sensors to punch through some interference—the EPS may not be able to handle the demands placed on it. The quality and efficiency of the EPS determine how much power a starship can transfer around.

Isomagnetic EPS Conduits

By 2371, a new form of technology, isomagnetic conduits, were made available to make EPS systems on ships and facilities more efficient by using a series of isomagnetic constriction shielded casing as a power wave-guide network throughout the ship/facility. Even newer vessels, such as the Premonition, Republic, and Ascendant-class, use even further specialized sheathing on their conduits that can emit chroniton particles, projection of a temporal SIF field throughout the vessel to prevent against temporal anomalies and similar temporal phenomenon. This upgrade can be applied to any vessel equipped with Isomagnetic EPS conduits.
