Resource Adequacy
Why power systems plan enough supply and deliverability to serve expected demand under uncertainty.
Where this fits
Why power systems plan enough supply and deliverability to serve expected demand under uncertainty.
Core system ideas
Resource adequacy considers whether sufficient resources are likely to be available when demand is high.
Planning needs to account for outages, weather dependence, transmission limits, storage duration and demand uncertainty.
Installed nameplate capacity alone does not describe dependable contribution during stressed conditions.
Interfaces and tradeoffs
Planning uses scenarios because demand, resource additions, retirements, weather, project timing and technology are uncertain. Models are decision aids rather than perfect predictions.
What organizations measure
Peak demand, dependable capacity, reserves, loss-of-load risk and forecast uncertainty.
