Electric Power Monthly with data for May 2011, Report Released: August 16, 2011
“Net generation in the United States was down 1.3 percent from May 2010 to May 2011. The National Oceanic and Atmospheric Administration (NOAA) reported that the average May temperature across the contiguous United States was 1.0 degree F above the long-term average for May. The Federal Reserve reported that industrial production was 3.4 percent higher than it had been in May 2010, the seventeenth consecutive month that industrial production was higher than it had been in the corresponding months of the previous year. As it had been in March and April 2011, the rise in conventional hydroelectric generation was by far the largest absolute “fuel-specific” increase as it was up 7,871 thousand megawatthours, or 31.6 percent. The increased generation from the contiguous Pacific Coast States accounted for 64.6 percent of the national rise. NOAA reported that snowpack remained “much above normal” in the Northwest and Northern Rockies and that the spring in the Northwest was the wettest on record. Wind generation showed the second-largest increase over May 2010 totals as it was up 33.5 percent. Increased wind generation in Texas, Iowa, California, and Oklahoma accounted for 56.9 percent of the national growth, but increases were widespread, as only six of the thirty-eight States that had wind generation reported less to EIA in May 2011 than they reported in May 2010. Delaware, Maryland, and Rhode Island, which did not have wind generators that reported in May 2010, had wind generation in May 2011. Natural gas-fired generation showed the third-largest absolute increase over May 2010 as it was up 2.8 percent, or 2,032 thousand megawatthours. Increased gas-fired generation in Louisiana and Pennsylvania accounted for 90.8 percent of the national gas-fired rise in generation.”
