Are they part of the TNEB tenure? What field of smart metering?
The gist of it is these smart meters work on a wireless mesh network so can talk to each other and operate in such a way that they are tamper proof which is something none of the competitors have been able to achieve. The beauty of this is that they have costs down equivalent to sending a man out to check the meters by hand, so it is not expensive either. $8 billion a year is lost in India to electricity theft/tampering, so you can see why this is so important.
So they are the same smart meters currently widespread in America, the Netherlands, etc...
No idea what TNEB is, but cyan aren't the only horse in this race, in fact I'm sure of it. My company has been doing this since before 2007.
Just looked up some stuff, no they aren't competing in India for smart metering but they pretty much have the UK and Europe wrapped up.
