In September 2012, all new electricity generation came from solar and wind projects, according to the Energy Infrastructure Update (PDF) issued by the Federal Energy Regulatory Commission's Office of Energy Projects. Five wind projects totaling 300MW and 18 solar projects totaling 133MW came online during the month.
The Energy Infrastructure Update also noted that nearly half (43.8%) of new generating capacity coming online in 2012 through September involve renewables: 77 wind projects (4,055MW), 154 solar projects (936MW, 76 biomass projects (340MW), 7 geothermal projects (123MW), 10 water power projects (9MW), and one waste heat project (3MW).
The looming expiration of hte Section 1603 Treasury Cash Grant and the Production Tax Credit (PTC) is likely a significant driver of this end of year surge. See our October 18 post Economist Weigh in on the PTC Extension for our latest on the PTC.
