Your energy breakdown

Your energy breakdown is the fancy feature in My OVO that splits your energy consumption into individual appliance categories.

Using the magical power of data ‘disaggregation’, it shows you where your biggest energy costs are, plus the impact of any changes you make to your energy use.

How does it work?

It’s all thanks to your Smart Meter. When it’s set to share half-hourly data, the information we have on your overall energy use is coming to us regularly enough that we can categorise or ‘disaggregate’ it. 

It works in two ways:

True energy breakdown

The appliances in your home all act in unique ways. We can identify their impact on your energy bill by comparing patterns in your energy use to the patterns of energy used by typical appliances. 

We can also look at how much energy you’re using in the middle of the night to give us an accurate idea of your ‘standby load’. Eg. the energy you’re using on appliances that are never switched off properly. 

True energy breakdown will disaggregate 55-65% of your energy use. 

Rule-based energy breakdown

The last 35-45% is split by looking at statistics for things like, the energy consumption of people in your local area, the weather, and the season. 

Eventually, you’ll be able to select items you have in your home to make this form of breakdown even more accurate.

Note: Unfortunately solar power generation has a negative impact on the accuracy of the energy breakdown results.
