Are Policies to Encourage Wind Energy Predicated on a Misleading Statistic?

Based on the concept of a “capacity weighted error,” previous researchers have concluded that wind energy is moderately predictable. However, using data from nine electricity control areas as evidence, our analyses reveal that the wind energy forecast errors measured relative to mean wind energy production are very large. Wind energy forecasting errors have implications for action undertaken to ensure reliability. [Copyright &y& Elsevier]
