Turbine Availability Cost Calculator
What each percentage point of availability is worth across a wind farm year.
O&M contracts argue over availability points — here's what one point actually costs. Set downtime hours to 87.6 (1% of the year) on your farm's MW and tariff, and the result is the rupee value of every availability percentage point in your next contract negotiation.
Lost energy = MW × hours × seasonal CF. This is the number that justifies condition monitoring: a planned 24-hour gearbox swap in the low-wind season versus a 3-week emergency in monsoon winds can differ by 50× in lost revenue.

Frequently asked questions
How much does wind turbine downtime cost?+
Lost energy = MW × hours × the period's CF; revenue = that × tariff. A 2 MW machine down 10 days at 35% seasonal CF and ₹3/kWh loses ~₹5 lakh in energy alone, before crane and crew. The calculator does your numbers and adds the repair line.
Why does outage timing matter so much in wind?+
Because CF is seasonal: an Indian turbine down through a monsoon week loses 3× what the same fault costs in November. This is the entire argument for condition-based maintenance — the RUL tools here exist to move repairs into the cheap season.
What availability should an O&M contract guarantee?+
97% time-based availability is the common floor; premium contracts reach 98%+ or energy-based availability (which weights windy hours properly). Each point is worth ~87.6 hours × your fleet's hourly revenue — price contract negotiations with exactly this calculator.
How do I value lost generation in a warranty or insurance claim?+
Document the outage window, apply a defensible CF for that period (same-month historical or neighboring-turbine actuals — not the annual average), multiply by tariff. The per-hour figure this tool produces, backed by SCADA logs, is the standard claim arithmetic.
