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.

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

From kettles…

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

How they use them over time
TechWorld 2011 – 17th November 2011. Copyright © Onzo 2011.
And how they all add up

Which makes itemised smart bills possible

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

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

Appliance Condition
We know when it is about to fail. Here the compressor is not cycling.

So we can warn the consumer

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.
This ability does not just improve existing business models, it allows completely new ones, as well as new business opportunities.
Generating insight and value from data
