Is Your Electricity Use Actually Trending Up?
Paste historical electricity consumption values and see the average, total change and a simple linear trend. This helps distinguish a one-off spike from a persistent direction.
What a consumption trend can reveal
A sequence of monthly or weekly electricity readings can show whether use is broadly rising, falling or remaining stable. Looking across many periods is often more useful than reacting to one unusually high bill.
Trend does not mean causation
A rising trend does not identify the cause. Changes in weather, occupancy, equipment, production, operating hours or tariffs may all occur at the same time.
Why chronological order matters
The trend calculation uses the order in which values are supplied. Reordering the same numbers can change the slope because the time relationship changes.
Use this alongside a baseline
A baseline tells you what normal consumption looks like, while a trend shows direction. Using both can make energy monitoring more informative.
FAQs
Does the trend predict future bills?
No. It describes the historical pattern entered into the tool.
Can I use monthly data?
Yes. Monthly kWh values are a natural use case.
What is the slope?
It is the estimated average change in kWh per period from a simple linear fit.
What if the values are highly seasonal?
A simple linear trend can be misleading. Compare like seasons or use a seasonally normalized analysis.
