This table shows the residual mix calculation based on eGRID subregions. These rates were calculated using the data collected by Green-e® Energy during annual verification of 2015 certified sales and the 2014 emissions and generation data provided by eGRID in the U.S. for each eGRID subregion in eGRID2014.
