Build a custom load profile

By default Reonic builds a synthetic consumption curve from the household's annual kWh and type. When that shape isn't representative (shift workers, a home office, an electric household with unusual habits), you can override it with a custom load profile, a distribution you set yourself that the simulation uses instead.

Before you start

• You're working on the project's Energy demand in the Planning view, signed in with editor rights or higher.
• Have the customer's real consumption shape in mind: when they actually use electricity across the day and year. The annual total can stay the same; the shape is what you're changing.

Build the profile

1. Open the project's Energy demand and choose to set the consumption shape yourself rather than use the synthetic profile.
2. Set the monthly distribution: twelve values describing how consumption is spread across the year.
3. Optionally set the hourly distribution: a typical weekday and weekend day.
4. Save. Reonic builds the 15-minute consumption curve the simulation runs on from the distributions you entered.

Note: The profile is often shown as a percentage of the annual total, not in kWh, so the shape can be re-scaled if the annual figure changes. The annual total is set separately.

Things to know

• The profile is stored on this project. You set the shape per project, so plan to enter it again on each project where you need a custom curve.
• Other consumption sources are available if a hand-built profile isn't what you need: the synthetic profile (from annual kWh plus household type) and, in France, a measured Linky/PDL curve from the grid operator.
• The profile feeds the rest of the simulation. The consumption curve is an input to the household energy balance, and the shape you set here is the deeper version of the consumption section you tune when setting the tariff and reading profitability. See Profitability and Energy flows.
• *Uploading a measured load-curve file (a Lastgang, German for the recorded consumption-over-time curve) is a commercial-project feature. The file must match Reonic's accepted CSV format. For residential projects you build the profile in the editor; the file importer is on the commercial side. This is covered in more depth in Commercial planning*.
