FS Super: Over the past decade, wind and solar have provided the bulk of additional generation capacity to the National Electricity Market (NEM), replacing retired coal and gas-fired plants. Despite a significant number of regulatory and policy changes directly affecting the relative economics of the different sources of generation, wind and utility-scale solar generation capacity has more than doubled, from 2.3GW in 2012 to 4.8GW in July 2018, with a strong acceleration over the past 24 months, in particular for utility-scale solar.
