The 2016 Carrawayan Blackout was a nationwide power outage that cut electricity to everywhere on Carraway Island dependent on the electric grid on Wednesday, January 20, 2016 at approximately 2:04 a.m. CIST.
The outage was caused by a computer bug at a control room in Nestem that inhibited notification regarding several downed transmission wires during an unseasonably strong winter storm. This caused a domino effect, leading to several transmission wires being overloaded and tripping out, eventually leading to the loss of power for the entire island.
Power was restored to nearly the entire island by 4:40 p.m. CIST via the reinstitution of localized power generation facilities in more rural, secluded counties; however, the City of Adustelan had no such facilities that were able to be recommissioned quickly (the nearby Incuba Nuclear Power Plant, the only once viable option, was decommissioned fully by 1987). As such, the nation's largest and most important city was left in the dark, save for a few hospitals and government buildings running on generators, for several days, crippling the local economy in the short term.
Power was restored to Adustelan by 6:00 p.m. CIST on Friday, January 22, 2016.
