Deep dive into electricity curtailment in America’s highest renewables penetration markets.
This is a revealing new analysis by Grid Status assessing the rising trend in curtailed energy in the three highest renewable energy penetration markets in the United States – California ISO (CAISO), the Electric Reliability Council Commission of Texas (ERCOT), and the Southwest Power Pool (SPP). The article uses a mix of illuminating graphs including visualization charts, to examine curtailment drivers including, low-demand periods, transmission congestion, and the impact of self-scheduling capacity. All have varying degrees of influence on the three markets examined. With more and more wind and solar resources connecting to the nation’s power grid, expect more curtailment – especially during shoulder seasons — periods of lower demand and higher transmission outages.
