RE dominates new US capacity

Wind and solar were 86.9% of new power generation capacity installed by the US in May, with natural gas a distant third with 11.8%, according to the Federal Energy Regulatory Commission (FERC).

FERC’s monthly Energy Infrastructure Update shows that wind led new build and expansions with 203MW, followed by solar 156MW and gas 49MW. The balance was biomass and small hydro.

In January through May, the US installed 3.13GW of power generation capacity, down from 7.58GW in the same 2013 period.

Gas led all energy source installations through May with 1.43GW, about one-third 4.39GW a year earlier. Solar was next with 907MW, down from 1.05GW and wind was third with 678MW versus 962MW.

Analysts predict the US will add between 12GW and 13GW of wind capacity this year and in 2015.
