The graph plots load in millions of A against date from 26 January 2014 to 31 December 2018. The load varies between about 0.9 and 2.4, with repeated seasonal rises and falls. Model 2014 and Model 2015 alternate between step levels near 1.25 and 2.07, with sharp transitions around several date ranges. The model lines align with higher load periods near 2015, 2016, 2017, 2018, and the end of 2018.Load estimations for model 2014 and model 2015 on training data
