3. Speakers
Poul Berthelsen has been working in the Utility industry for 7 years --
initially and has always been active in the distribution side of the
business, having technical responsibility for the remote reading system.
Since 2007 he became responsible for the technical content of the
tender procedure and evaluation of bids within NRGi
NRGi.
Varun Nagaraj brings more than 20 years of high tech product
high-tech
planning and strategy success and experience to Echelon. Varun was
the CEO of NetContinuum (acquired by Barracuda Networks), served
as EVP of Marketing and Customer Operations for Ellacoya (acquired
by Arbor Networks), and was VP of Product Management and
Marketing at Extreme Networks.

25. Key Lessons Learned
 Use proven technology
 Best meter on the market
 Proven software
 Communication system is important
 Success rate >99.9% daily collection (data collected 4 times a day)
 Firmware updates should be possible
 Allows you to add more functionality
 Focus on integration
 Sh ld not need t visit meters after installation
Should t d to i it t ft i t ll ti
 Implementation and integration is complicated
