A few reactor units began powering up over the weekend (Oyster Creek, Arkansas Nuclear 1), but a few units also reduced capacity (Pilgrim, Columbia Generating Station), which netted out to a decline in output from Friday by about 0.5%.
As of today, the natural gas replacement value of outages in 2016 is greater (by 0.01 BCFD) than 2015, and that difference will likely grow over the next week.
