Fill out this short survey to let us know how you use eGRID, what data you currently use, what features you would like in subsequent versions, and suggestions for improvements. document.write(theDate.getFullYear()) CO2output emission rates may fluctuate on an annual basis due to a change in the resource mix (the percentage of generation from each fuel type). *This link leads to the machine-readable files that are made available in response to the federal Transparency in Coverage Rule and includes negotiated service rates and out-of-network allowed amounts between health plans and healthcare providers. GGL is calculated by dividing the estimated losses by the result of total disposition minus net interstate exports minus direct use: The U.S. Energy Information Administration (EIA) provides data on estimated losses (reported at the utility level via form EIA-861, and then allocated to States based on the utility's retail sales by State), total disposition (i.e., the sum of station use, direct use, retail sales, sales for resale, and other outgoing electricity), net interstate exports, and direct use (i.e., electricity consumed onsite for all operations other than electric power plant station use) at the state level in the State Electricity Profiles. All of the regional transmission organizations in the United States also function as balancing authorities. What are the regional emission rates and resource mix? Replaced Boiler file with new Unit file; included the entire universe of units; not just the subset of boilers with unit-level data from EPA/CAMD or EIA. Western Interconnection-Wide Regional Reliability Policy Facilitator-WECC facilitates the identification of issues specific to reliability, creates an opportunity for discussion of the issues, and represents region-wide issues and policies at the state and federal levels. This usually occurs near the borders of two subregions. Also, an excel version, White zone exactly 15% reserve margin The ISO is the largest of about 38 balancing authorities in the western interconnection, handling over two-thirds of the electric load in the West through the Western Imbalance Energy Market (Western EIM). Balancing authority area (generally smaller regions of the power grid in which all power plants are managed to balance power system demand and supply); eGRID subregion; and NERC region, as designated by the North American Electric Reliability Corporation (plus Alaska, Hawaii, and Puerto Rico). Most carbon footprint calculators that are applicable to the United States use eGRID data. A balancing authority (BA) is an entity in the US electric system (as well as in parts of Canada and Mexico) that is responsible for grid balancing: resource planning and unit commitment ahead of time, maintenance of the load-interchange-generation balance within a balancing authority area (also known as a control area) and support for real-time eGRID2012 and subsequent editions (and associated materials) reference previous eGRID editions using the new naming convention and the files available for download from the website use the new naming convention; however, the content within the previous editions of eGRID, such as the technical support documents, has not been revised. 13353 BerlinTel: +49 (0)30 89 06 42 55 E-Mail: anfrage@wecc.de, Westhafen Event & Convention CenterCookie-SettingsImprintPrivacy policyAVB.
