The document discusses the UK's planned smart metering system to install 47 million smart meters and supply 27 million In-Home Displays by 2019. It will provide two-way communication between utilities and customers to allow remote reads, time-of-use tariffs, and remote enablement/disablement of supply. This system is intended to provide benefits like energy savings, reduced costs, and decreased CO2 emissions for consumers and utilities. It also discusses how the large amount of data generated can be used to develop new services and business models through data analytics.

Between 2014 and 2019, the UK is planning to install over
47 million smart meters and supply 27 million In Home
Displays to domestic consumers.

7. The growth of data
The transitions through this data path for utilities are massive.
Each step increases the volume of data that needs to be
captured and processed by a factor of thousands. For the
UK population, that’s:
Analogue world – 30 million readings / year
Smart metering – 500 billion readings / year
Smart living – 900 trillion readings / year
It needs a special levels of expertise to capture, store and
analyse this quantity of data in a cost effective way.

12. Engaging the Customer
Otherwise why will they bother?

15. The Value of Data
How we know this and what else we can learn
TechWorld 2011 – 17th November 2011. Copyright © Onzo 2011.

16. Appliance Inference – Applying intelligence
We read real and reactive
power every second from a
single feed from our sensor.
The data is compressed
using wavelet compression
to reduce the data flow by a
factor of around 20:1.
We have amassed a
database of 1600 household
devices to perform blind
detection of appliances.

17. From kettles…
TechWorld 2011 – 17th November 2011. Copyright © Onzo 2011.

18. To multiple appliances
TechWorld 2011 – 17th November 2011. Copyright © Onzo 2011.

19. Users can see the effect of each appliance
TechWorld 2011 – 17th November 2011. Copyright © Onzo 2011.

20. How they use them over time
TechWorld 2011 – 17th November 2011. Copyright © Onzo 2011.

21. And how they all add up

22. Which makes itemised smart bills possible

23. But there’s more…
Data analytics mean utilities can develop new services

24. Appliance Condition
We know what a fridge looks like when it's working:

25. Appliance Condition
We know when it is about to fail. Here the compressor is not cycling.
TechWorld 2011 – 17th November 2011. Copyright © Onzo 2011.

26. So we can warn the consumer

27. Generating insight and value from data
This ability does not just improve existing business models, it allows
completely new ones, as well as new business opportunities.
Customer Support Knowing which appliances are being used and when?
Alerting customers to change in usage when new appliances
are detected. Knowing when it is the right time to call.
“Nudge Tariffing” Determining which customers have the capacity to change
their usage patterns by analysing current usage. This is far
more effective than the blunt stick of dynamic pricing.
HVAC Providing smart climate control that uses appliance detection
and derived occupancy to adjust the HVAC to optimise
performance and comfort levels.
Smart Maintenance Detecting appliances in use and their condition to allow
intelligent preventative service plans to be offered.
Assisted Living Monitoring usage patterns to support independent living.
EV Charging Determining the household use patterns that can gauge when
and how much to charge an electric vehicle.
Virtual Power Operators Providing the usage information to allow Virtual Power
Operators to tailor tariffs to individual users on a daily basis.
