Emergency power Emergency power was an energy resource used for operating a starship or spacedock during an emergency situation . Rerouting emergency power to warp engine s on an vessel is enough to push them to eighty percent of maximum . ( ) As well , emergency power can be diverted to transporter s , thruster s , environmental control , deflector shield s , or structural integrity for use in extreme low power circumstances . ( ) Emergency power can also be used to give a boost to force field energy . ( ) In 2153 , Malcolm Reed announced that he had restored emergency power to but most of their primary systems were offline after encountering a spatial anomaly in the Delphic Expanse . ( ) Later that year , Captain Jonathan Archer had emergency power diverted to hull plating after encountering another anomaly in the Expanse . ( ) After the heavy damage " Enterprise " took at the fierce battle at Azati Prime , Lieutenant Reed reported to T ' Pol that the emergency power had come back online again and they would have phase cannon s back in an hour . ( ) In 2154 , " Enterprise " was under attack at by Vulcan starships on the orders of Ambassador V ' Las . Commander Charles Tucker III ordered emergency power be sent to the phase cannons to keep them operable . ( ) In 2259 of the alternate reality , navigator Darwin reported to that the ' s emergency power had dropped to fifteen percent and was rapidly declining while the ship was caught in Earth ' s atmosphere . ( ) In 2265 , Spock told Captain James T . Kirk that the was on emergency power cell s after being severely damaged during their first encounter with the galactic barrier . ( ) In 2267 , Captain Kirk ordered that engineering supply the " Enterprise " with full emergency power and have the warp engines on standby while it was under attack and surrounded by the Romulan s in the Romulan Neutral Zone . ( ) While trying to prevent the stolen space cruiser " Aurora " from entering Romulan space in 2269 , Captain Kirk ordered that emergency power be diverted to the tractor beam s so the " Enterprise " could stop them . ( ) As the " Enterprise " was on a scientific mission to study the creation point in the galactic core , the ship was pulled into the center by a matter - energy whirlwind . Montgomery Scott reported to Captain Kirk that he did not know how much more emergency power they could take before the ship started to break up . ( ) In the mid - 2270 s , Captain Kirk ordered engineering to provide full emergency power so the " Enterprise " could free itself from the powerful tractor beam " V ' ger " had seized upon it . However , Spock reported that they only had a fraction of the power necessary to break free , so Kirk had engineering disengage all main drive systems . ( ) In 2285 , the " Enterprise " came under attack from Kruge ' s Bird - of - Prey in orbit of the . Kirk ordered that the " Enterprise " engage emergency power and prepare to return fire , but the torpedo shot fired from the Klingon vessel destroyed the " Enterprise " s automation center , leaving it dead in space . ( ) In 2364 , Galaxy - class starships under normal circumstances had sufficient emergency power to maintain life support for months absent any other power source . ( TNG : " The Last Outpost " ) Aboard the , Geordi La Forge activated the emergency power cells and was fascinated that they were still working . ( ) Captain Jean - Luc Picard requested emergency power for the medical lab to seal a quarantine . ( ) When Geordi La Forge was in command of the he rerouted emergency power first to the deflector shields and later to the deflector s . ( ) In 2365 , while the " Enterprise " - D was trapped inside a " hole in space " by Nagilum , the ship began to lose power but the ship ' s computer reported that emergency power had been engaged . ( ) On the planet Rutia IV in 2366 , one of Kyril Finn ' s followers in the Ansata asked aloud if they had any emergency power in their underground cavern they were hiding in when the illumination went out . ( ) " In the anti - time present of 2370 , Captain Picard ordered that emergency power be transferred to the antimatter containment system so the " Enterprise " - D could maintain a static warp shell in order to destroy a temporal anomaly threatening Humanity . " ( ) Thomas Riker , after stealing the from Deep Space 9 for use by the Maquis , ordered that emergency power be transferred to the vessel ' s shields after an attack by a Cardassian cruiser . ( ) In 2371 , the had encountered a power drain in a chamber located inside an asteroid belonging to the Vidiian s . Captain Kathryn Janeway had B ' Elanna Torres go to emergency power but it had no effect on the power drain . ( ) " In an alternate timeline , Deep Space 9 was under attack by the Romulans and sustained damage to their shield generator s . Just prior to the station ' s destruction , Major Kira Nerys ordered that phaser s be rerouted to emergency power couplings . " ( ) In the Delta Quadrant , Captain Janeway tried to save the life of Ptera , a female Vhnori , whose pattern was degrading in the transporter . Despite ordering Ensign Seska to shunt emergency power to buffer tank four , she still died . ( ) In The Doctor ' s elaborate delusion on " Voyager " s holodeck in 2371 , the ship ' s computer reported to him that during a Kazon attack , the vessel was restricted to emergency power and auxiliary systems only . ( ) " Voyager " was attacked in 2372 by the Kazon and a torpedo from one of their vessels blew out " Voyager " s containment generator . B ' Elanna Torres asked Kathryn Janeway ( who was actually from the future ) if she should reroute emergency power or take the ship ' s warp core offline . Janeway asked her to use her best judgment . ( ) Later in 2372 , Chief Miles O ' Brien reported to Major Kira that the was losing emergency power after being accidentally damaged by a cloaked mine in Bajoran space . ( ) Later that year , " Voyager " was being bombarded with proton burst s from an unknown source , which heavily damaged the ship . Lieutenant Tuvok reported that " Voyager " s primary systems were offline and they were running on emergency power only . ( ) Jadzia Dax , temporarily the ' s science officer , reported to first officer Worf that she was picking up a distress call from the which was attacked by the Jem ' Hadar and was losing emergency power . ( ) In 2373 , Ensign ordered two " Voyager " crewmembers to reinforce the ship ' s containment field s and to reroute emergency power to keep the vessel from falling into the hands of the Nyrian s . ( ) When " Voyager " was under attack from Species 8472 bio - ship s , Ensign Harry Kim reported that the shields and weapons were offline . However , Tuvok was able to reroute emergency power to the torpedo launcher s , which allowed " Voyager " to destroy their ships with bio - molecular warhead s . ( ) While traveling on board Jem ' Hadar attack ship , damaged severely after narrowly escaping from the destruction of a ketracel - white facility , Chief O ' Brien reported that almost everything on the ship was offline but emergency power was holding . ( ) " In an alternate timeline , Tuvok suggested that if he and Seven of Nine were to reroute emergency power to the Jefferies tube junction they were currently in and erect a level ten force field , it might contain an explosion from a chroniton torpedo lodged in the hull . Later , Captain Janeway ordered that emergency power be rerouted to the damaged navigational deflector to deflect micrometeoroid s , but it was unsuccessful . " ( ) In 2375 , Captain Janeway used a power cell to get emergency power back online on " Voyager " while the ship was trapped in " " . ( ) On the IKS " Rotarran " in 2375 , Commander Worf ordered that emergency power be rerouted to the secondary shield emitters while they were planning to decloak and attack Trelka V , where a Dominion starbase and a Cardassian drydock were in orbit . ( ) On " Voyager " s holodeck , Harry Kim and Tom Paris were conducting a simulation into a problem Paris found with " Voyager " s new quantum slipstream drive . After twenty - three simulations , Kim suggested rerouting emergency power to the deflector a bit earlier , but Paris said it would not help . ( ) Later that year , Commander Chakotay had emergency power diverted to the holodeck , so The Doctor and a holographic representation of Crell Moset could continue working . An an alien vessel was draining " Voyager " s power with a tractor beam . ( ) In 2375 , Captain Picard had his shuttlecraft attached to a malfunctioning Data ' s scoutship by docking clamp s . When Data discovered Picard ' s shuttle was attached to his , he engaged extreme evasive maneuvers while in the atmosphere of the Ba ' ku planet to get Picard to detach his shuttle . However , Picard had Worf reroute emergency power to inertial dampener s which , after the craft was stabilized , allowed him to capture Data . ( ) The " Delta Flyer " s port nacelle took a hit from the Borg Queen ' s vessel in 2375 , which caused it to vent plasma . Tuvok attempted to reroute emergency power but it was not enough . ( ) Just prior to the final battle of the Dominion War , the Female Changeling expressed annoyance as to why the power in her briefing room on Cardassia was going out . She was informed by Legate Broca that it was sabotage by the Cardassian Liberation Front . ( ) Responding to a distress call aboard a Kraylor vessel , Medical Transport 136 , Ensign Kim and Neelix beamed aboard . Kim asked Terek to watch a readout as he routed emergency power to structural integrity . ( )
