Load profile kWh calculator

Use this calculator when a load is better described as operating blocks than as one average kW value. Australian project examples include workshop production and standby periods, retail trading and after-hours blocks, plant operation during cleaning, tenancy fit-out schedules and early facility energy reviews.

The result is a profile summary. It totals the rows the user enters and reports daily kWh, period kWh, peak row kW and the row contributing the most energy. It does not import interval data, apply a tariff, interpret a bill or calculate maximum demand.

Field Use Cases

The profile is most useful when rows are named in the same language as the site schedule. "Row 1" is weak. "Trading hours lighting and small power" gives the reviewer a chance to test the assumption later.

Profile Row Checklist

Rows should describe the same site and period. Do not mix a production row from one week with a cleaning row from a different season unless the record explains why.

Result Boundary

The peak row is not a demand charge value. It is the largest kW row entered into this worksheet. Demand billing normally depends on metering windows and tariff rules, so it belongs in a separate demand-charge record if needed.

Review Workflow

1. Define the site, board, tenancy or load group represented by the profile.
2. Split the operating day into up to three meaningful load blocks.
3. Enter the electrical input kW for each active row.
4. Enter hours per day and duty factor for each active row.
5. Enter the number of days in the estimate period.
6. Check daily kWh, period kWh, peak row and largest energy row.
7. If only one row is active, decide whether the simpler energy-cost calculator owns the task.
8. If the total will feed tariff comparison, confirm the tariff period matches the profile period.
9. Export the record only when row labels, source values and period assumptions are clear.

This workflow gives a compact profile for early review without pretending to be metering software.

Worked Australian Examples

These examples are row summaries only. If actual interval data is available, keep it as the controlling source and use this page only for a simplified worksheet.

Related Tools

Use energy cost when the profile has been simplified to one load and one tariff. Use tariff scenario when the period kWh is ready to compare two entered rate assumptions. Use load current when a row kW needs to become current for cable or switchboard review. Use maximum demand when the task is a board or supply demand worksheet rather than energy use.

Stop Points

• Rows describe different sites, meters or unrelated periods.
• kW values mix electrical input, motor output and measured demand without notes.
• Duty factors are guesses with no operational basis.
• Peak row kW is being treated as a metered demand charge value.
• Period kWh is being compared with a tariff period that does not match.
• The result is being treated as a retailer bill model or energy review conclusion.

Keep row labels, kW, hours, duty factors, days and source notes with the export. The result is a compact profile worksheet, not a metering import or full tariff model.
