Solar plants typically install more panel capacity relative to their inverter capacity

A solar photovoltaic (PV) system’s panel capacity is often reported in direct current (DC), while operating capacity in the United States is reported as it is delivered to the grid in alternating current (AC). For economic and engineering reasons, capacity values reported in DC typically are 10% to 30% higher than those reported in AC […]

U.S. nuclear outages were less than 3% of capacity this summer

September 28, 2015 Source: U.S. Energy Information Administration, Outages at U.S. nuclear power plants were extremely low this summer (June through August), averaging 2.9 gigawatts (GW), or less than 3% of total U.S. nuclear capacity. During four days in August, outages dropped to just 0.1 GW out of a total U.S. nuclear capacity of 98.7 […]

Electric generator capacity factors vary widely across the world

September 8, 2015 Source: U.S. Energy Information Administration, Note: Capacity factors reflect actual generation as a percent of continuous operation at full capacity. The technologies used to generate electricity are similar across regions of the world, but the pattern of use for those generating technologies can be significantly different. Analysis of electric generating plant utilization […]

Alaska increases wind power capacity in utility- and distributed-scale projects

September 1, 2015 Source: Source: U.S. Energy Information Administration, Although wind power provided less than 3% of Alaska’s electric power generation in 2014, Alaska’s wind power capacity has increased 20-fold between 2007 and 2014, growing from 3 megawatts (MW) to 60 MW. This increase is notable in light of the challenges of installing and connecting […]

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

Coal, nuclear, and renewables expected to boost Vietnam’s electricity capacity

August 3, 2015 Source: International Atomic Energy Agency, 2013 Vietnam Country Nuclear Power ProfileNote: Hydroelectricity includes pumped storage. Vietnam is poised to significantly transform its electrical power generation mix over the next two decades as it modernizes the country’s agrarian economy to become a more industrialized nation. To accommodate greater industrial expansion and to support […]

China will soon surpass South Korea, Russia, and Japan in nuclear generating capacity

July 20, 2015 Source: U.S. Energy Information Administration, International Atomic Energy Agency, World Nuclear Association Nuclear power currently makes up slightly more than 2% of China’s total power generation. However, the Chinese government has a stated goal to provide at least 15% of overall energy consumption by 2020 (increasing to 20% by 2030) from non-fossil […]

U.S. refinery capacity reaches 18 million barrels per day

June 25, 2015 Source: U.S. Energy Information Administration, 2015 Increased refinery runs—based on increases in both capacity and utilization—have helped accommodate increases in U.S. crude oil production. The United States’ capacity to refine crude oil into petroleum products—measured as operable atmospheric crude distillation unit (CDU) capacity—increased by 0.2% in 2014, reaching 18.0 million barrels per […]

Projected electric capacity additions are below recent historical levels

In the coming decades, additions to U.S. electricity generation capacity are expected to be lower than in the recent […]

Crude oil storage at Cushing, but not storage capacity utilization rate, at record level

March 23, 2015 Source: U.S. Energy Information Administration, After increasing for 15 consecutive weeks, crude oil storage at Cushing, Oklahoma, reached 54.4 million barrels on March 13, according to EIA’s . This volume is the highest on record, but not the highest percent of storage utilization, as working storage capacity at Cushing has also increased […]

Scheduled 2015 capacity additions mostly wind and natural gas; retirements mostly coal

March 10, 2015 Source: U.S. Energy Information Administration, Electric Power Monthly Note: Other renewables include hydroelectric, biomass/wood, and geothermal. In 2015, electric generating companies expect to add more than 20 gigawatts (GW) of utility-scale generating capacity to the power grid. The additions are dominated by wind (9.8 GW), natural gas (6.3 GW), and solar (2.2 […]

U.S. crude oil storage capacity utilization now up to 60%
