Big Blackout

A sudden blackout cuts the electricity to an entire city, state, country, etc.

This is probably caused by a machine that sucks way too much energy. Sometimes the power is adequate and the machine works, other times it begins a quest for the heroes to find something that is powerful enough.

Alternately, it could be caused by a giant Electro Magnetic Pulse.

Usually just caused by natural disasters or accidents in real life; the citizens of television must see the power company as extremely unreliable.

Often illustrated by a distance shot of an entire city at night (blackouts never start during the day), with large rectangular sections of the city going out one-by-one, about a second apart.

Anime

 * Happens in The Big O when they try to jump-start Big Fau.
 * In Neon Genesis Evangelion, all the power in Japan is needed to power up the Positron Rifle, causing a (planned) nation-wide blackout.
 * Matariel also arrived conveniently in the middle of a daytime blackout. Since the power grid of NERV HQ had multiple backup systems, it HAD to be sabotage.
 * Happens in Highschool of the Dead when a submarine fired an EMP missile to completely wipe out all electronics in the city. Thankfully it happens in daylight whereby the protagonists have time to react.
 * In the OVA Giant Robo The Animation, a key part of the backstory is the "Tragedy of Bashtarlle", a test of an experimental Phlebotinum drive Goes Horribly Wrong, causing an blackout of all power sources worldwide that lasted for seven days, killing two-thirds of the world's population. (The explosion at ground zero also annihilated the country where the test took place. Guess the country's name - we'll wait.) The Big Bad's plan revolves around three MacGuffins meant to power a Phlebotinum Bomb that would repeat the effect of the original disaster.

Comics

 * In the Batman: Hush storyline, Batman follows a lead to Gotham City on Poison Ivy's whereabouts, only to find that she's used her poisons to control Superman's mind. After initially getting away, Batman gets the drop on Superman and electrocutes him with a main power line. All of the lights in Metropolis (which is generally shown to be a highly modern, borderline Crystal Spires kind of city) momentarily go off. Superman was only stunned for a short time, but Batman was only buying time until he could break Ivy's control anyway.
 * Ex Machina: Zeller's arrival triggers one of these, knocking out all the power in the state of New York, and a little beyond that. The name of the arc where this takes place? Power Down.
 * Spider-Man foe the Shocker once initiated a series of blackouts, one block at a time, in a pattern to spell out his name when viewed from above.

Fan Fiction

 * A small blackout strikes Hinamizawa when a storm strikes in Kyon: Big Damn Hero. It apparently happens a lot, hence most houses having a generator.
 * Happens in the Danny Phantom story, Stolen Years when.

Film
"Chris Knight: "Relax. That's just the fuses at the substation, they'll have it back on in a minute. Maybe I shouldn't have shorted across the building transformer. But more important: did we get a charge?""
 * The Deneuralizer in Men in Black II.
 * Superman Returns, when Lex Luthor throws a shard of the Fortress of Solitude into a small pool of water.
 * The supercomputer in Superman III.
 * National Lampoon's Christmas Vacation, when Clark Griswold finally gets his Christmas lights working. We cut to a shot of his house like a beacon in the midst of his suburb, as all the lights around his house dim from the power drain he's causing to the suburb. Then we cut to a shot of the "Auxiliary Reactor" switch in a nearby nuclear power plant, which is turned on (implicitly) because of the amount of electricity he's using.
 * Happened in Fantastic Four. Don't ask how Reed managed to hook in the Baxter Building to the entire city's power grid.

 * Interesting variation in the climax of Iron Man, which involves a power generator being overloaded and draining power from the surrounding area; however, unlike most of the 'plunge entire city into blackout' examples, it was clearly only a few blocks that were affected.
 * One of these accompanies the appearance of the UFO craft at the start of Close Encounters of the Third Kind.
 * The suspense film The Trigger Effect involves a massive (seemingly nationwide) power outage, the cause of which is never revealed.

Literature

 * In The Dresden Files book Dead Beat, baddies do this to Chicago in order to create a panic, as it knocks out not only building power but all electronics in the area, although phones and cars still work sporadically for some reason.
 * It's a jamming effect, but phones and cars have their own power source, so they're easier to work. After all, anything powered from the mains need everything down the power transmission to be working, a cellphone only needs the phone and the tower to be clear.
 * The Phil Rickman novel, December, describes a large blackout in Liverpool that occured on the day John Lennon was shot.
 * In the French Sci Fi novel Malevil, a blackout is the first effect that World War III has on the characters. The lights fail alongside an obnoxious blaring radio going silent. They have enough time to realize that the radio didn't break, the dial light works, but it's no longer receiving radio signals when the blastwave hits them.
 * Atlas Shrugged ends with all the lights in New York City going out.

 * Occasionally used on Hustle, when they'll cut power to a single specific block or something.
 * NCIS has the seventh season episode "Power Down". Team Gibbs has to solve the case using old-school methods. Poor McGee was stuck with the duty of looking through the boxes of files.

It's really an EMP satellite, and what we get to see is an image of all the lights going out on the North American continent...the entire continent.

Western Animation

 * Kim Possible first encounters Señor Senior Senior and Junior after tracing a Europe-wide blackout to their mansion. It wasn't something they were doing on purpose (they hadn't yet taken up villainy) -- they'd overloaded the power grid with extravagances such as Junior's blimp-sized sunlamp.

Real Life

 * The northeastern United States and Ontario saw massive blackouts in 1965 and 2003. New York City had another one in 1977.
 * "Does that sound particularly slow to you?"--WABC-AM disc jockey Dan Ingram in 1965, noting that the songs he was playing were slowing down (due to decreasing frequency as the electric grid slowly collapsed).
