FERC says renewables were 99% of new generating capacity in June and 91% in H1 2024. 37 “units” of solar totaling 2,192 megawatts (MW) were placed into service in June along with one unit of hydropower (34 MW). Combined, they accounted for 98.9% of all new generating capacity added during the month….
