Audited planning profile

This lean three-year profile applies a 0.75× editable baseline across 36 model periods to the household electricity projection model.

USE THIS PROFILE TO

Compare resource use or environmental impact with the same boundary, quantity and time horizon.

DECISION RULE

Review both the projected result and the assumed recurring change before relying on the forecast. Treat the lean scale as a lower-bound plan and test whether essential fixed costs still fit. Run an adverse case for inflation, downtime and changing demand over three years.

NOT INCLUDED

Emission factors, lifecycle boundaries, grid mix, water stress and local waste treatment differ by source and location.

VERIFY BEFORE ACTING

Use a dated, regional factor from an official inventory or recognized lifecycle dataset and state the boundary.
