On 14 July 1976, the dam's first generator went online.

But one generator wasn't going to do the job.

And once we get the generator going we'll have power for tools.

They had come up to see why the generator had gone off.

Honestly, the only reason they needed our help was because the generator went down.

Everybody more or less expected the generators to go pretty soon.

The first generator went on line in December 1973 and remaining three soon followed.

And the generator is not going to shut off for thousands of years.

Then that generator overheated and went down for half an hour.

That night, the generator went down, and the hospital was plunged into darkness.
