AWAKEN Field Site and Wind Farms

ARM SGP

The AWAKEN field campaign is taking place in northern Oklahoma, in proximity to the DOE Atmospheric Radiation Measurement (ARM) Program’s Southern Great Plains (SGP) facility. The SGP covers 55,000 acres and includes more than 30 instrument clusters.

Wind Plants

Five wind plants south of the central SGP facility comprise the AWAKEN field campaign area. Details about each plant are located in the table below.

Net capacity factors are calculated as an average from the annual net generation values reported by the U.S. EIA. (“Electricity plan level data for oklahoma,” https://www.eia.gov/opendata/v1/qb.php?category=902967, Last accessed on 2022-12-30.) Data for the first year reported by the EIA are not considered in the calculation.
