Wind, solar bring 100% of new US power capacity in Sep 2018
November 6 (Solar) – A bit over 700 MW of large-scale wind and solar farms became operational in the US in the month of September, with no other sources adding any capacity for the month.
In the first nine months of the year, meanwhile, natural gas was the leader in terms of new additions with 12.11 GW, followed by solar with 3.04 GW and wind with 2.75 GW.
The 200-MW Persimmon Creek Wind Farm in Oklahoma, a 160-MW wind farm by Rattlesnake Power LLC in Texas, and the 182-MW Midway Solar park in Texas were the biggest renewable energy facilities to go into service in September, according to the latest report by the Federal Energy Regulatory Commission (FERC).
