How to read your electricity usage graph

Many electricity bills in Spain include a usage graph.

Most people glance at it and ignore it, yet it is one of the most useful parts of the bill.

Understanding this graph helps explain why your bill changes and whether your tariff suits how you actually use electricity.

What the electricity usage graph shows

The usage graph usually displays:

  • Electricity consumption over time
  • Daily or monthly usage levels
  • Seasonal patterns

It shows when your home uses the most energy, not just how much.

Why usage patterns matter more than price

Your usage pattern is often more important than the price per kWh.

For example:

  • Homes that use more electricity during the day may benefit from solar-based tariffs
  • Homes with higher evening usage may need time-of-use pricing

Choosing a tariff that does not match your pattern leads to unnecessary costs.

Seasonal changes and lifestyle factors

Electricity usage often changes through the year.

Common reasons include:

  • Air conditioning in summer
  • Heating or hot water in winter
  • Pool pumps or irrigation systems
  • More time spent at home during certain months

A single average price does not reflect these changes.

How we use your usage data

When you upload your electricity bill, we use the usage graph to:

  • Understand when you use electricity
  • Check whether your tariff fits your habits
  • Identify savings opportunities
  • Assess suitability for options like Octopus Sun Club

This allows us to make recommendations based on real data, not assumptions.

Frequently Asked Questions

Hva om strømregningen min ikke inneholder en forbruksgraf?

Noen eldre eller forenklede regninger viser kanskje ikke en graf. Du kan imidlertid alltid få tilgang til detaljerte forbruksdata ved å registrere deg på distributørens nettportal (f.eks. i-DE, E-Distribución).

Endrer solenergi hvordan jeg bør lese denne grafen?

Ja. Hvis du har solcellepaneler, vil forbruksgrafen din fra nettet falle betydelig i soltimene. Å sammenligne dette med appen for solcelleproduksjon gir det fulle bildet av det totale energibehovet ditt.

Kan forbruksmønsteret mitt påvirke hvilken tariff som er best for meg?

Absolutt. Hvis du bruker mesteparten av energien om natten, kan en elbil-tariff være best. Hvis du jobber hjemmefra med klimaanlegg, kan en flat-rate eller sol-tilpasset tariff spare deg mer.

Hvorfor endres forbruket mitt selv når vanene mine føles like?

Været er den største faktoren. Oppvarming om vinteren og klimaanlegg om sommeren bruker mye mer strøm enn lys eller småapparater, noe som forårsaker topper selv om din daglige rutine ikke har endret seg.
