NEW DELHI (AP) - Officials in northeastern India say that the power grid in that region has collapsed, the third one to fail in a massive, cascading blackout.
The failures across the three power grids Tuesday afternoon left more than half the country without electricity.
Earlier Tuesday, the northern and eastern grids collapsed.
The collapse of the grids Tuesday afternoon came a day after the northern grid failed and left eight states without power for much of the day.
Shailendre Dubey says the northern grid collapsed about 1:05 p.m. Tuesday. Dubey is an official at the Uttar Pradesh Power Corp. in India's largest state.
S.K. Mohanty says the blackout in the eastern grid was triggered by a fault and could take several hours to resolve. He is a power official in the eastern state of Orissa.
