Audited planning profile

This lean five-year profile applies a 0.75× editable baseline across 60 model periods to the home lighting rate model.

USE THIS PROFILE TO

Estimate recurring household operating cost and compare practical energy-use choices.

DECISION RULE

Treat 100% as the hard limit and preserve a margin when demand or usage is uncertain. Treat the lean scale as a lower-bound plan and test whether essential fixed costs still fit. Treat maintenance, replacement and compounding assumptions as material over five years.

NOT INCLUDED

Local tariffs, taxes, seasonal efficiency and regulated charges are not inferred automatically.

VERIFY BEFORE ACTING

Check a recent bill, device specification and current tariff before committing to a purchase or retrofit.
