Electricity Running Cost Verification Checklist PDF

Full QC Checklist+

Verify load input accuracy, rate/billing structure, cost calculation/interpretation, and efficiency/practical application.

✓24 Inspection Points

✓4 Verification Categories

✓Load Input Accuracy+

Actual nameplate/rated watts used for major equipment, not guessed from a generic chart
Hours per day and days per week realistically estimated, not assumed to run continuously
Standby/phantom power considered for electronics left plugged in but not actively used
Quantity field used correctly for repeated items, not double-counted as separate identical rows
Seasonal variation considered for weather-dependent equipment, not applied as a flat year-round estimate
All significant equipment included when the goal is a whole-house bill estimate, not just a few items
True watts distinguished from nameplate VA (apparent power) for motor-driven or inductive equipment

✓Rate & Billing Structure+

Electricity rate per kWh confirmed from an actual utility bill, not estimated or assumed
Tiered/slab rate structure acknowledged if your utility uses one, since this calculator assumes a single flat rate
Time-of-use/peak-off-peak pricing acknowledged if applicable, since this calculator uses one rate regardless of time of day
Monthly service/standing charge included only when estimating a full bill, excluded when comparing equipment running cost
Currency and rate units confirmed to match — rate entered as cost per kWh, not per some other unit
Additional bill line items (taxes, surcharges, fuel adjustment charges) accounted for separately, since this calculator only models energy cost plus one flat service charge

✓Cost Calculation & Interpretation+

Month/year averaging convention understood — an average 30.4375-day month, not a specific calendar month
Cost share percentages used to correctly identify the biggest contributors to total cost
Standby power's cumulative annual effect recognized, even though its per-hour draw looks small
Result sanity-checked against an actual utility bill where possible
Result used for relative comparison between equipment or scenarios, not treated as a guaranteed exact bill figure

✓Efficiency & Practical Application+

Result used to evaluate an appliance replacement/upgrade decision with a genuine cost comparison
Highest-value energy-saving opportunities identified first, using the cost share breakdown
Understood that motor-driven, cycling loads (like a refrigerator's compressor) have a variable real-world draw this estimate approximates as constant
Local utility rebate or efficiency incentive programs checked separately, not assumed included in this estimate
Future electricity rate changes considered for any multi-year planning or payback calculation
This calculator not treated as a substitute for a professional home energy audit for larger decisions

Inspection Notes+

Use the latest approved drawings, specifications, and site measurements.

Complete all critical checks before proceeding to the next work stage.

Record deviations and confirm rectification where required.

Inspection Notes

Use the latest approved drawings, specifications, and site measurements.

Complete all critical checks before proceeding to the next work stage.

Record deviations and confirm rectification where required.

Use it after collecting the project inputs and again before approving or closing the relevant work stage.

No. It supports verification but does not replace approved drawings, specifications, codes, manufacturer requirements, or professional inspection.
