The cost of unplanned downtime in power generation plants

Quick answer

Unplanned downtime in power generation plants is among the most expensive losses in the plant because a single failure, such as forced outages from boiler, turbine, or auxiliary failures, can stop the flow, not just one asset. The true cost pairs lost contribution margin with emergency labour and expedited parts, and is usually several multiples of the repair itself.

Frequently asked questions

Why is unplanned downtime so costly in power generation plants?
Because failures such as forced outages from boiler, turbine, or auxiliary failures often stop the whole flow, so the lost production dwarfs the repair cost. Forced-outage rate and availability drive revenue, so reliability and outage discipline are the core levers.
How do I estimate downtime cost for my site?
Multiply downtime hours by the lost contribution margin per hour, then add emergency response cost. The free downtime cost calculator does this from your own inputs.
