How does wind power contribute to overall generation capacity adequacy?

S: Wind power in ERCOT contributes to overall generation capacity adequacy. The capacity contribution from wind generation is based on historic performance over 20 peak load hours in each season. ERCOT is continuously working on improving the assessment methodology of SPAWCC.

What is the capacity contribution of wind?

In the analysis by PacifiCorp of several prospective wind locations, the capacity contribution of wind averaged approximately 20% of rated capacity. This capacity value from the IRP is used as part of an evaluation to determine how much additional capacity is needed to meet future load forecasts.

Does wind power have a capacity value?

Wind power has varying availability, but can still possess a capacity value, although often lower (as a percentage of installed capacity) compared to conventional power plants. A range of capacity value estimation approaches have been considered in different power systems.

Does wind power increase capacity margin?

Other Norwegian studies have shown that wind power can increase the capacity margin and reduce the loss of load expectations in regions limited grid capacity [ 57 ]. The capacity credit of wind power in such areas was found to be significantly improved if wind power plants are spread over a large area.

What is the capacity adequacy of wind power in Germany?

S: The contribution of wind power has been considered in the capacity adequacy calculation with a factor of 1%. The capacity factor of wind power in Germany has been a constant value over the last years. The main capacity challenges in Germany occur on in the regions from North-East to South-West with limited grid capacity.

Does inter-annual variability of wind generation affect a capacity metric?

Inter-annual variability of wind generation can affect capacity metrics. Therefore, we recommend using multiple years of data for capacity value calculations. If that is not possible, several approaches covered in this paper may be useful.
