Electrical Power Interruption Cost Calculator — Price Lost Production and Restart Time
Estimate the financial impact of an electrical interruption by separating lost production time, restart expense, labor impact and event frequency.
Interruption cost inputs
Why outage cost is different from electricity cost
During an interruption, energy consumption may fall to zero while the financial consequence rises sharply because production stops, equipment needs restarting or personnel must respond.
Lost production
Hourly production value multiplied by interruption duration estimates the direct time-based production impact.
Restart cost
Restart cost captures an event-specific consequence that does not scale linearly with minutes of downtime.
Recurring annual exposure
Event frequency converts a single outage estimate into a yearly planning figure, making reliability investments easier to compare.
Worked example
A 45-minute event at $1,200/hour has a $900 production-time impact before restart, labor and other costs are added.
Limitations
Real interruption costs can include product scrap, contractual penalties, safety consequences, customer impact and long recovery times. Add them as separate assumptions where material.
Frequently asked questions
Can different interruption durations be modeled?
This version uses an average duration. Use a separate scenario for materially different event types.
Does the calculator estimate reliability?
No. It monetizes a user-defined interruption pattern.
Can the total be zero?
Yes, if event frequency or all cost assumptions are zero.
