Monthly renewables performance report

These graphs display monthly minimum, mean, median, and maximum net load ramps, daily and monthly renewable curtailments, frequency of negative prices in the real-time market, control performance, and reliability-based control. 

Greenhouse gas (GHG) emissions tracking

These reports depict greenhouse gas emissions for the ISO balancing authority as a direct result of the dispatch of ISO internal resources, net imports (including dynamic resources) and transfers from western Energy Imbalance Market (EIM) entities into the ISO. See Tracking Methodology and Frequently Asked Questions.  


Wind and solar daily curtailment report 

These reports provide a detailed accounting of wind and solar renewable generation curtailed in the ISO market. Read these reports in the context of the daily renewables watch reports for a more complete understanding of both renewable curtailment and generation.
