West Coast wind patterns lead to below-normal wind generation capacity factors

August 11, 2015 Source: U.S. Energy Information Administration, Forms EIA-860 and EIA-923Note: Calculations are based on the output of wind plants in operation before 2010. , were consistently below the previous five-year average during the first five months of 2015, according to the latest data available. Capacity factors for wind turbines are largely determined by […]

South Africa: Localised Energy Generation Is Solution to Eskom Crisis, but We Need Managed Localism

analysis By Saliem Fakir Two forms of anarchism will further imperil the energy crisis – first there’s Eskom’s anarchic pursuit of large power stations like the nuclear plant. Second, there’s the fact that those citizens and corporations who can afford it, are following their own path in response to the financial crisis and mismanagement within […]

Levelized cost comparisons help explain value of various electric generation technologies

June 3, 2015 Source: U.S. Energy Information Administration, Note: Costs reflect utility-scale systems and include federal tax incentives for renewables as applicable in 2020 under current law. IGCC is integrated gasification combined cycle; CCS is carbon capture and sequestration. Capacity additions reflect electric power sector additions only, and include planned capacity already under construction as […]

Under the proposed Clean Power Plan, natural gas, then renewables, gain generation share

May 27, 2015 Source: U.S. Energy Information Administration, EIA’s of the Environmental Protection Agency’s proposed Clean Power Plan rule shows it would result in major changes in the fuel mix used to generate electricity in the United States. Under the Base Policy case in EIA’s analysis, which uses the as the proposed rule comes into […]

Power generation from coal and natural gas expected to temporarily converge this spring

Power generation from the two fuels is expected to rise at similar rates […]

Natural gas, renewables projected to provide larger shares of electricity generation

May 4, 2015 Source: U.S. Energy Information Administration, Republished 1:15 p.m. May 4, 2015 to correct an error in the graph. EIA’s (AEO2015) Reference case projects that electricity consumption will increase at an average annual rate of 0.8% from 2013 to 2040, nearly in line with expected population growth. Continuing a recent trend toward lower […]

Wind generation seasonal patterns vary across the United States

February 25, 2015 Source: U.S. Energy Information Administration, Forms EIA-860 and EIA-923 Note: Data include facilities with a net summer capacity of 1 MW and above only. Wind plant generation performance varies throughout the year as a result of highly seasonal wind patterns. Nationally, wind plant performance tends to be highest during the spring and […]

New England generation fuel mix changes likely as Vermont Yankee nuclear plant retires

February 2, 2015 Source: U.S. Energy Information Administration, On December 29, 2014, Entergy shut down its Vermont Yankee nuclear facility after 42 years in service. Vermont Yankee had a capacity of 604 megawatts (MW), generating nearly five million megawatthours (MWh) of electricity per year since 2010. As the fifth-largest source of generation in New England, […]

California drought leads to less hydropower, increased natural gas generation

October 6, 2014 Source: U.S. Department of Agriculture The drought in California continues to increase in severity since California’s governor declared a state of drought emergency in January 2014. As of September 30, 58% of the state was classified as experiencing exceptional drought, the most intense drought category. These dry conditions limit hydropower generation, requiring […]

Saudi Arabia uses largest amount of crude oil for power generation since 2010

September 24, 2014 Source: U.S. Energy Information Administration, Saudi Arabia is one of a handful of countries that burn crude oil directly for power generation, according to the (JODI). During the summer, Saudi Arabia typically experiences an increase in electricity consumption as domestic demand for air conditioning rises. Saudi Arabia burned 0.9 million barrels per […]

European nations are increasing electricity generation using no-carbon sources

September 22, 2014 Source: U.S. Energy Information Administration, International Energy StatisticsNote: . Penetration rates of no-carbon generation have increased from 50% to 56% in recent years in Europe, as European Union countries work toward renewable energy and greenhouse gas emissions targets. Increasing levels of renewable generation, along with nuclear generation, mean that many European countries […]

Reasons for projected natural gas-fired generation growth vary by region

August 15, 2014 Source: U.S. Energy Information Administration, Reference case Note: Values for the Northeast Power Coordinating Committee, Midwest Reliability Organization, and Western Electricity Coordinating Council regions account only for the portions of these regions within the United States. Totals exclude electric generation in the end-use sector, which is largely onsite industrial generation. WECC is […]

Nonhydro renewables now routinely surpass hydropower generation

July 31, 2014 Source: U.S. Energy Information Administration, Electric Power Monthly and Short-Term Energy Outlook April marked the eighth consecutive month that total monthly nonhydro renewable generation exceeded hydropower generation. Only a decade ago, hydropower—the historically dominant source of renewable generation—accounted for three times as much generation in the United States as nonhydro renewable sources […]

The Columbia River Basin provides more than 40% of total U.S. hydroelectric generation

June 27, 2014 Source: U.S. Energy Information Administration, from . Hydroelectric power plants located in the Columbia River Basin account for a little more than one third of all the hydroelectric capacity in the United States. The Columbia River runs from the Canadian Rockies and flows 1,214 miles through Idaho, Oregon, and Washington, but the […]

Projected growth in natural gas-fired generation is influenced by resource availability

June 13, 2014 Source: U.S. Energy Information Administration, Note: All generation values are for net generation. Different scenarios of natural gas resource availability in the (AEO2014) Reference case, High Oil and Gas Resource case, and Low Oil and Gas Resource case affect the growth of natural gas-fired electric generation. As increasing amounts of natural gas […]
