The power drill that is being used to drill the southern Indian state of Kerala into a deep freeze has been given the go-ahead by the state government.
The drill, which was supposed to take place on Saturday morning, has been delayed to Thursday night as the power company has been told it must make some changes to make it more efficient.
The state government had initially planned to start the drill on Friday but decided against it due to the high temperatures.
The power company said the delay had been due to technical problems with the power generator, which had been given a green light.
Kerala is one of the few states that has not had a power crisis in recent times.
The country has had a severe power shortage since November 2014, when a massive power failure at the Fukushima nuclear plant triggered a chain reaction of power cuts and blackouts.
