Energy Data Analytics in Cardiff
Analytics on consumption and generation data for Cardiff energy businesses. The commercially important property here is that forecast error is not symmetric — being short costs differently from being long, and at different times of day — so a model tuned to minimise average error can be worse in money than one that is worse on paper.
Why this comes up
The problem
There is a dashboard showing yesterday's consumption, and no view of the exposure the position creates tomorrow.
What you get
What we deliver
- Forecasts evaluated on cost of error rather than on accuracy alone
- Half-hourly granularity handled properly, including clock changes
- Weather brought in, since it explains most of the variation you care about
- Anomalies distinguished from meter faults, which look similar in the data
- Portfolio views that aggregate without hiding the sites driving the risk
- Privacy considered where consumption patterns identify a household

Energy Data Analytics in Cardiff — common questions
- Why does asymmetric error matter?
- Because imbalance is priced, and the price differs by direction and by period. A forecast that is consistently slightly long may cost far less than one that is occasionally very short, so optimising the model against pounds rather than percentage error changes what you build.
- What breaks with half-hourly data?
- The clock changes. Two days a year have forty-six or fifty periods, and pipelines built on the assumption of forty-eight fail quietly on those days — usually by dropping or duplicating an hour that then propagates into settlement and reporting.
- How do we tell a fault from real behaviour?
- By pattern rather than by threshold. A meter reading zero could be a closed site or a dead device, and the distinction usually lies in what the surrounding periods and comparable sites did. Alerting on value alone produces noise nobody acts on.
- Is aggregated data safe to share?
- It depends how small the group is. Aggregation over a handful of sites can still identify individual behaviour, particularly where one large consumer dominates, so a minimum group size and a check on dominance should be part of how the data is published.
- Do you work with businesses across Cardiff?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Wales, including Cardiff and the surrounding Cardiff area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Cardiff businesses do you usually work with?
- Public sector and broadcast work is common, and bilingual provision is usually a requirement rather than an option. Beyond that we work across Media & Broadcasting, Financial Services, Public Sector, Higher Education and Sport.
- Do you cover the areas around Cardiff?
- Yes — we work throughout Wales, including Bristol, Swansea. Cardiff is an urban area of roughly 490,000+, and we take on work across the wider Cardiff region rather than the city boundary alone.
