In India, more than 600m people were affected by a power cut after three electricity grids collapsed suddenly. The power failure created chaos, with whole cities grinding to a halt and transport and other services badly hit. The blackouts in the northern, eastern and north-eastern grids affected 20 of India's 28 states. Engineers have worked through the night to get the power systems back online.
In a TV statement on Tuesday evening, Power Minister Sushil Kumar Shinde blamed the crisis on certain states taking more than their quota of power from the national grid. He said he had appealed to states to stop this and instructed his officials to strongly penalise those states which broke quotas.
is working on solutions to such problems by using social networking and smart demand tools to help reduce peak loads on grids and reduce demand in emergency situations.
