What do you consider Big Data to be?
Big data is a broad term for data sets so
large or complex that traditional data
processing applications are inadequate.
Challenges include analysis, capture, data
curation, search, sharing, storage, transfer,
visualization, and information privacy.

The Challenge
In UK, £1.7 Bn of energy
consumed is not managed
Large businesses waste around
15% of energy due to lack of
efficiency measures
£5Bn spent on new buildings
each year, which use 2-3 times
more than designed
Return on investment (ROI) of
48% available for many measures
Effective management will
reduce risk and increase security
of supply
Market transformation via
Awareness of problem
Understanding of technical
performance
Opportunities for socio-
technical change

What can analytics say about energy usage?
Turning Data into Actionable Information;
Predicting and classifying costs when there is a shift in the type of
tariff, e.g. shifting to a real-time tariff from a fixed price tariff.
Clustering of load profiles, determining behaviour type and
response by the consumer
Determining fundamental drivers of energy consumption

How is big data best collected and stored, and
who ought to have access?
Data costs, to both move and store, BIG DATA costs A LOT!
Maximise value of data once you have it by making it uniformly
accessible to business functions
Increasingly common that energy information is handled on
behalf of the retailer by a third party contractor.
Lack of standards in all aspects of data formats
Changing energy management provider is an epic task.
Example, we have partnerships within WICKED with four
different retailers, four different configurations of data and
inconsistent metadata.

Retail uses analytics regularly in sales, now it can move to
other parts of the business,
Answer fundamental questions on efficacy of operational
changes w.r.t energy
Connect consumption to overall business performance.
Editor's Notes
Here we have clustered domestic smart meter data from small scale trials, also utilised commercial datasets to establish the impact of the introduction of real-time pricing on different types of business
Estimated that energy theft is a £500M/year problem.
