US utility solar power generation dominated by crystalline silicon panels
70% of U.S. utility-scale solar PV capacity used crystalline silicon modules rather than thin-film Most of the growing number of installations of utility-scale solar photovoltaic (PV) operating capacity across the United States have been systems that make use of crystalline silicon panels, according to the U.S. Energy Information Administration. In 2016, 70 per cent of […]
Coal stockpiles at US power plants have fallen since last year
57% of US coal-fired electricity generating capacity had over 60 days of burn In Aug. 2017, coal stockpiles at electric power plants were 144 million tons, the lowest monthly level since late 2014, according to EIA’s Electric Power Monthly. Coal stockpiles at U.S. coal-fired power plants typically follow a seasonal pattern of increasing during the spring […]
Hurricane Harvey caused electric system outages, affected wind generation in Texas – EIA
Wind speeds reached 130 mph as Hurricane Harvey made landfall Hurricane Harvey caused substantial electricity outages, as power plants and transmission infrastructure—particularly in south Texas and along the Gulf Coast—were affected by high winds and significant flooding, according to the U.S. Energy Information Administration. At its peak, more than 10,000 megawatts (MW) of electricity generating […]
Wind energy continues rapid growth in 2016 – US Dept. of Energy
Texas, Oklahoma, and Iowa lead the nation in wind energy The Energy Department released three wind market reports demonstrating continued growth in wind energy nationwide. America’s wind industry added more than 8,200 megawatts (MW) of capacity last year, representing 27 per cent of all energy capacity additions in 2016. In 2016, wind supplied about 6 […]
US news brief July 24: House passes bill to speed up natural gas pipeline permits
Also in news brief: American Midstream sells propane business for $170 million, US House moves to streamline permitting process of natural gas pipelines As the California power grid adapts to increased solar electricity production, wholesale power prices are rising in the morning and evening hours, according to the US Energy Information Administration. The higher hourly prices in […]
U.S. petroleum refinery capacity continues to increase
U.S. crude oil production 0.5 million b/d lower in 2016 than 2015 As of Jan. 1, 2017, U.S. operable atmospheric crude distillation capacity reached 18.6 million barrels per calendar day (b/cd), 1.6 per cent higher than at the beginning of 2016, according to EIA’s annual Refinery Capacity Report. This increase in operable capacity was slightly lower than last […]
Monthly US renewables electricity generation surpasses nuclear for first time since 1984
Net generation from nuclear power has remained flat since late 1990s, renewables rising slowly as investment increases In March, and again in April, U.S. monthly electricity generation from utility-scale renewable sources exceeded nuclear generation for the first time since July 1984, according to a U.S. Energy Information Administration press release. This outcome reflects both seasonal and […]
Coal and natural gas battle for share in power markets
In US West, coal and natural gas remain in close competition for electricity power for past decade In 2016, natural gas provided 34 per cent of total electricity generation, surpassing coal to become the leading generation source, according to the U.S. Energy Information Administration. Natural gas first exceeded coal as the most common electricity fuel […]
Oil-fired power plants provide small amounts of US electricity
Oil-fired generators generally used to meet peak demand electricity times Roughly 70 per cent of petroleum-fired electric generating capacity that still exists today was constructed prior to 1980, according to the US Energy Information Administration. Utility-scale generators that reported petroleum as their primary fuel comprised only 3 per cent of total electric generating capacity at the end […]
US nuclear generation expected to decline as power plants retire
Capital investment needed to extend life of nuclear plants beyond 60 years is currently unknown Nuclear power currently accounts for about 20 per cent of electricity generation in the United States, playing an important role in electricity markets, according to the US Energy Information Administration. EIA’s 2017 Annual Energy Outlook (AEO2017) Reference case assumes that about […]
