Actually California doesn't have the best track record in power reliability!
California ranges from 60 minutes of outages (SDGE) to 931 minutes of outages (Pacificorp)

In this slide, http://desismartgrid.com/wp-content/uploads/2012/07/Towards-..., for North delhi power limited (NDPL), they improved their SAIDI from 56 to 47 minutes.
So, (very ironically) - you are correct - it's not unreasonable to say that there are parts of California that are one order of magnitude worse than areas of India.
I realize that's not the point you were trying to make, but I always find it interesting to chase the data and see what it has to say.
From a bigger picture, though - California really does have notoriously bad power quality in terms of outages, not even including the rolling blackouts (http://en.wikipedia.org/wiki/California_electricity_crisis) we had back in 2000/2001 (and justified me being allowed to purchase about $500K worth of generators, Diesel Belly tanks, and UPS systems for our server room)
On my walk to work, at least once a month in the morning, I hear all of the buildings in Redwood City firing up their generators to do their monthly tests - nobody "relies" on PG&E Power for critical services, they plan for the outages.
Just as a comparison - I'm in Singapore right now, and their SAIDI is .53 minutes/year. I've yet to see a generator being tested outside of Critical Facilities like data centers/emergency facilities.
New Delhi is the capital. The north has less of a shortage, but capitals (like Chennai) are usually more insulated from blackouts anyway so looking at them alone will give you a poor idea.
Also, do your figures include planned outages? Many places in TN, India have daily planned outages called load shedding.
OP was talking about Rwanda, not India. 60 minutes per year, as disastrous as it sounds for California, is hardly comparable with the outages of several hours per week they have there.
I get it, I get it, California life is hard, but seriously...
Your Indian company is a quasi-government entity (or government influenced entity, I didn't dig into it very far) intended to improve quality of service in the the capital city of the country.
Wikipedia says the SAIDI for the U.S. is ~1.5 hours, so NDPL should anyway survive comparison to some more relevant U.S. providers (but I speculate that you have not found an average provider for India).
