BYOT was the right path
• Positions us in a constantly evolving technology landscape
• Offer customer choices
• Move towards electronic/paperless program management
• Able to know device is active now and tomorrow
• Streamline operations via aggregator
• Allow future adoption of DR (and more) via single platform

So how are we doing?
21
Launched in 45 days
2,500+ devices enrolled
(Almost half way to goal)
A few lessons so far• Engage legal early around customer data and
agreement
• Be aware of variability across thermostat vendors
• Off the shelf vs. customized
• Need a third-party aggregator to herd the cats
• Multi-vendor implementation can introduce some challenges
• Customer experience is harder to control/manage22
How do we get to IDSM?
• In the hands of regulators now to approve filing
• All BYOT devices enrolled capable of DR
• Same platform and enrollment tools can support dual EE + DR
• Planning to offer combo EE + DR incentive
• Not stopping at DR (teaser for Tom Hines)
