Power-Quality Improvement Savings Comparator — Compare Reliability Investment Value
Compare a baseline electrical system with a proposed power-quality improvement by combining avoided interruption costs, energy-loss savings, maintenance changes and project investment.
Baseline and improvement assumptions
Why power-quality improvement should be evaluated financially
A power-quality project can create value in several ways. Avoided interruptions may dominate the economics, while lower electrical losses and maintenance may provide additional recurring benefit.
Avoided event cost
The calculator multiplies the reduction in events by the user-entered cost per event.
Energy savings
The difference between annual loss energy in the two scenarios is valued at the entered electricity price.
Maintenance savings
Annual maintenance is compared separately so operational savings are not hidden inside the event-cost assumption.
Simple payback
Investment divided by annual net operating benefit gives simple payback when annual benefit is positive.
Limitations
A serious investment case may require reliability statistics, measured power-quality data, downtime distribution, financing assumptions and risk analysis.
Frequently asked questions
Does this prove an improvement will pay for itself?
No. It evaluates the assumptions you enter.
Can the improved scenario have higher energy loss?
Yes mathematically. The result will reflect that rather than forcing an artificial saving.
Can avoided event savings be zero?
Yes, when event frequency is unchanged.
