Wind capacity additions mostly came in the SPP region last year, and it shows. Monthly generation has been consistently beating prior year, and this January is an extreme example.
Average output for the month to date has been around 6.2 GW, while it was closer to 4.1 GW last year. Here are the daily averages, with January '16 in grey, and January '17 (to date) in red. If all this new power generation offset natural gas fired turbines, it would equate to roughly 0.5 BCFD. That's a lot.
