Set an Electricity Consumption Baseline You Can Actually Use

Build a reference consumption level from historical electricity use, then compare a future period against that baseline. The calculator supports equal periods and makes the averaging method explicit.

What is an electricity consumption baseline?

A baseline is a reference level against which later electricity use can be compared. It is useful for energy-efficiency projects, operational monitoring, budgeting and evaluating whether consumption has materially changed.

Why averaging matters

A simple average is transparent, but the best baseline depends on the situation. Weather-sensitive buildings, seasonal businesses and changing occupancy may require a normalized baseline instead.

When an average baseline is appropriate

A simple historical average works best when the historical periods are reasonably comparable and there are no major changes that would make the older observations irrelevant.

When to use a more advanced model

If consumption depends strongly on weather, production volume, operating hours or occupancy, consider a baseline that normalizes those variables rather than relying on one unadjusted average.

FAQs

How many months should I use?

Use enough comparable history to represent normal operation. The right period depends on seasonality and the purpose of the baseline.

Can I use weekly data?

Yes. The periods simply need to be comparable.

Does the baseline predict future consumption?

No. It is a reference level, not a guaranteed forecast.

Can I use this for energy savings measurement?

Yes, as a simple reference, provided the compared periods are reasonably comparable.
