It would be very interesting to develop a grassroots effort to measure electricity reliability worldwide:
SAIDI — system average interruption duration index
SAIFI — system average interruption frequency index
Here are a couple of papers on the topic:

Re: Quantifying electricity reliability worldwide
Here is a related article from the US:

And the IEEE guide on the subject:
