What Could Your Electricity Use Look Like in Five Years?
Create a transparent electricity-use forecast from current consumption and three annual growth scenarios. The goal is planning, not pretending that a simple growth rate can predict every future operating condition.
How a simple electricity forecast works
A compound growth model applies the selected annual growth rate to the previous year's consumption. That makes assumptions explicit and easy to change, but it should not be mistaken for a detailed engineering forecast.
Why three scenarios are more useful than one number
Future consumption is uncertain. A conservative case can represent efficiency improvements or lower activity, an expected case can reflect the current planning view, and a high-use case can represent growth or electrification.
When this forecast can be useful
It can support budgeting, solar sizing discussions, storage planning, utility-cost projections and preliminary capacity planning when only limited historical information is available.
When a simple forecast is not enough
Use more detailed models when consumption depends strongly on weather, production, occupancy, operating schedules or a known equipment-installation plan.
FAQs
Does this forecast electricity bills?
It forecasts kWh. The entered electricity price can provide a basic cost context, but future tariffs are not predicted.
Can annual growth be negative?
Yes. A negative rate represents declining usage.
Does the model cap growth?
Rates below -100% are rejected because they would imply negative consumption.
Can I use this for a new building?
Only as a scenario framework. A new building normally needs an engineering load model rather than historical growth alone.
