Located at Level 5000 of the planet Coruscant, the central power distribution grid was a network of enormous generator towers. These towers supplied power to the entire ecumenopolis. In the course of the Clone Wars, a number of battles between the Galactic Republic and the dissenting Confederacy of Independent Systems, the grid was bombed under the direction of Count Dooku. Dooku, the Separatist Head of State, ordered the bombing to undermine peace talks between the two sides. This resulted in widespread fires and a complete planetwide power outage on Coruscant. Once it was confirmed that the Separatists were behind the attack, the Republic Senate turned down their proposal for peace. Even though the Coruscant power grid was eventually repaired, mandatory blackouts were implemented to conserve energy, and some areas of the planet rarely had access to electricity.
The central power distribution grid on Coruscant was initially seen in "Heroes on Both Sides," the tenth episode of Star Wars: The Clone Wars' third season, a canon animated series. The episode was originally broadcast on November 19, 2010.
