During the first half of this year, natural gas, solar and wind lead all sources when it comes to new utility-scale generating capacity to come online. This report from the Energy Information Administration (EIA) says that 4,350 megawatts (MW) of new utility-scale generating capacity came online, with natural gas making up the lion’s share of those additions but solar and wind made bigger proportional gains compared to the first six months of 2013.
Utility-scale capacity additions in the first half of 2014 were 40% less than the capacity additions in the same period last year. Natural gas additions were down by about half, while solar additions were up by nearly 70%. Wind additions in the first half of 2014 were more than double the level in the first half of 2013.
Of the states, Florida added the most capacity (1,210 MW), all of it natural gas combined-cycle capacity. California, with the second-largest level of additions, added just under 1,100 MW, of which about 77% was solar and 21% was wind, with the remaining additions from natural gas and other sources. Utah and Texas combined for another 1,000 MW, nearly all of it natural gas combined-cycle capacity with some solar and wind capacity in Texas.
In addition to the large additions by natural gas, solar saw strong year-on-year growth, adding 1,146 MW. Wind basically more than doubled the amount added in the same period last year, putting 675 MW generating capacity online.
