Wind curtailments during Winter Storm Elliott

All times are in Central Standard Time. SPP reports the amount of wind curtailed in its footprint, while MISO and PJM do not explicitly do so. To estimate the amount of wind curtailed in MISO and PJM, the 2021 annual average curtailment rate from LBNL's "Land-Based Wind Market Report: 2022 Edition" was applied to the reported hourly wind generation profile in the two regions. TVA's periods of rolling blackouts are in red, while Duke Energy's outage period is in blue (purple indicates overlap).
