Feb. 1 — In 2012, coal plants generated 91% of Victoria’s electricity, and natural gas plants provided just 2%, but coal supplied less than 83% of Victoria’s power in 2017, while gas-fired generation surged to 5%. The transformation of ERCOT’s generation mix has been similarly profound. Renewables supplied more than 18% of the grid’s power in 2017, almost all wind. That compares with 9.3% in 2012.
