Business owners concerned at India power cuts

A day after India's worst blackout, people are asking whether the country can handle its energy needs. The power cut left 640 million people - more than the entire population of the European Union - without electricity. The problems are structural, experts say. All three grids that overdrew power were linked, and an overload in one caused a cascading failure in the rest. Reports indicate that some regional authorities also ignored warnings from dispatch centres that monitor electricity loads. India's generation capacity is meant to increase by ten per cent annually to cope with rising demand. Last year, however, it increased by only half that amount. Citizens say the blackout has had wider financial repercussions - in an already struggling economy, the power cuts are making business owners nervous.
