💡 Good to know
All calculations use standard, published formulas and simplified assumptions so beginners can build intuition. For real projects, always consult qualified engineers and site-specific data.
Frequently asked questions
What is curtailment?
When a turbine is instructed to reduce or stop output - usually for grid balancing or contractual reasons.
What is availability?
The fraction of time a turbine is ready to operate. Modern turbines typically achieve 95-98%.
