Audited planning profile
This standard ten-year profile applies a 1× editable baseline across 120 model periods to the home lighting total model.
Use the total to test whether the plan fits the available budget, time or resource limit. Use this as the central case, then compare a lean and conservative profile. Use a wide uncertainty range; small recurring assumption errors compound substantially over ten years.
Local tariffs, taxes, seasonal efficiency and regulated charges are not inferred automatically.
Check a recent bill, device specification and current tariff before committing to a purchase or retrofit.
