Some clean renewables and alternatives to petroleum have added the most power-generating capacity in the first half of this year. The U.S. Energy Information Administration says out of the 4,350 megawatts of new utility-scale generating capacity to come online in the first six months of 2014, natural gas plants made up more than half of the additions, with solar and wind making up more than 25 percent and about 16 percent respectively.
Four plants accounted for the combined-cycle capacity additions — the new Riviera plant (1,212 MW) in Florida, expansions at the Lake Side Power Plant (629 MW) in Utah, and the Channel Energy Center (183 MW) and the Deer Park Energy Center (155 MW), both in Texas.
Significantly fewer combustion turbine plants were added (130 MW) compared to last year (3,120 MW), making the June 2014 year-to-date additions of natural gas plants overall about half the level of the same period last year.
Solar additions experienced strong year-on-year growth, with nearly 70% more additions in the first half of 2014 (1,150 MW) than in the same period last year (690 MW). About three-quarters of this solar capacity was located in California, with Arizona, Nevada, and Massachusetts making up most of the rest.
Wind additions (675 MW) were more than double the amount added in the same period last year (330 MW) and were concentrated in California, Nebraska, Michigan, and Minnesota.
California’s 228 MW of capacity additions came from the Alta Wind X and Alta Wind XI projects of the Alta Wind Energy Center (currently the largest wind farm in the United States at 1,548 MW of total capacity), while Nebraska’s 207 MW came from the Prairie Breeze wind farm. In Michigan, 61 MW of the Echo Wind Park plant came online as well as the 75-MW Pheasant Run II plant. In Minnesota, the 50-MW Lakeswind plant came online.
