Main reasons for wind power abandonment

Why is wind power abandoned?

Did wind curtailment exceed demand?

UCS commissioned analysis from Synapse Energy Economics to investigate wind curtailment in the Southwest Power Pool (SPP), a regional grid spanning from North Dakota to parts of Texas. The data is clear—there were no instances where wind energy supply could have exceeded demand.

Why does wind curtailment change over time?

Direct causes for curtailment change over time and across diferent provinces. The two phases of wind curtailment are caused by diferent mismatches. During the first phase, from 2010 to 2012, the main causes of curtailment were the rapid growth of installation and inadequate buildup of transmission grid in the early stage of development.
