Authorities in Pakistan were scrambling Monday to restore electricity throughout the country after an overnight countrywide blackout. Authorities blamed a "technical fault" for the breakdown that plunged the capital Islamabad and the rest of the nation into darkness for more than two hours early Monday. The 560-megawatt Uch Power Station in the south-western province of Balochistan tripped due to "an imbalance in supply and demand," which caused other major plants to automatically shut down in a domino effect, an official was quoted as saying by DPA. Rai Sikandar, senior official of the Ministry of Water and Power, said its technicians were trying to fix the problem. "We cannot restart all the grid stations at once," he said. "We will gradually do that."
