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.


Moving beyond Smart

Making it more than just automated metering


Onzo’s Smart Energy Kit – a Smart IHD

An energy harvesting, self-installed, high accuracy clamp.

An easy to read display with energy tools to help behaviour change.

and how they can help consumers


Engaging the Customer

Otherwise why will they bother?


It offers the consumer web engagement

The Value of Data

How we know this and what else we can learn


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


Users can see the effect of each appliance


How they use them over time


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
