[ 1] The principal difference between the currently-effective regional . Other EPA emission data sources also provide data on emissions associated with electricity generation. Typically, EIA will make corrections to previously issued EIA-923 data. Introduction . By documenting the environmental attributes of electric power generation, eGRID can help consumers and researchers to better understand the relationship between electricity and the environment. Download scientific diagram | Details of Balancing Authorities in WECC from publication: Issues for Consideration in the Wide-Scale Deployment of Plants Using Coal/Biomass to Generate Electricity . 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). Regional Entity- WECC is required by FERC to monitor and enforce compliance with reliability standards by users, owners and operators of the bulk power system in the United States. The electric grid in Western North America, known as the Western Interconnection (WI), serves over 70 million people in 14 states, two Canadian Provinces, and a portion of Mexico. In recent years, there have been several changes to the eGRID content, methodology, and presentation of data. The maps are representational, many of the boundaries shown on the maps are approximate because they are based on companies, not on strict geographical boundaries. 1899 Hoffenheim (Wirsol Rhein-Neckar-Arena). NERC provides industry-wide perspective and oversight, and the Regional Entities have unique features and activities that serve the needs of their regional constituents while ensuring that industry follows NERC Reliability Standards. 7 0 obj <> endobj The most recent eGRID subregion, NERC region, and the U. S. summary information can be found in summary tables available as either an Excel or PDF format. CO2/MWh) in some eGRID subregions are significantly higher than the rates in other regions. Fuel specific nonbaseload generationis added to the State, BA, NERC region, and US levels. CAISO manages 80 percent of the load . The direct connection to the BAB 100 is connected via the Beusselstrae and into the City via nearby S- and U-Bahn stations. The significant changes starting with the release of eGRID2012 include: More information about each of these changes can be found in the Whats New sections of the Technical Guide (formerly called Technical Support Document)available with each eGRID release. Kristopher.Bremer@PacifiCorp.com. The Central Valley Project (CVP) generation, owned by the Bureau of Reclamation, and Western Area Power Administration's transmission facilities, along with the 500 kV California Oregon Transmission Project (COTP), are included among other resources within the BANC footprint. The addition of Puerto Rico resulted in the addition of a new State (Puerto Rico; PR), Balancing Authority (Puerto Rico Miscellaneous; NA), eGRID subregion (Puerto Rico Miscellaneous; PRMS), and NERC region (Puerto Rico; PR) to the eGRID2019 files. The source of these emissions factors is Table C-2 ofEPAs Mandatory Rule on the Reporting of Greenhouse Gases (40 CFR Part 98). CAISO manages 80 percent of the load in California and a small portion of Nevada.The main balancing authorities in California are:CAISO - California Independent System OperatorBANC -Balancing Authority of Northern CaliforniaLADWP - Los Angeles Department of Water & PowerIID - Imperial Irrigation DistrictTID - Turlock Irrigation DistrictWALC -Western Area Power Administration, Lower ColoradoPacifiCorp WestNV Energy, California Electric Balancing Authority Areas, https://cecgis-caenergy.opendata.arcgis.com/maps/CAEnergy::california-electric-balancing-authority-areas, {"type": "Polygon", "coordinates": [[[-124.4096,32.5263],[-124.4096,41.9050],[-112.9475,41.9050],[-112.9475,32.5263],[-124.4096,32.5263]]]}.

The Council develops a plan, updated every five years, to ensure the region's power supply and acquire cost-effective energy efficiency. Balancing authorities are responsible for maintaining operating conditions under mandatory reliability standards issued by the North American Electric Reliability Corporation and approved by the U.S. Federal Energy Regulatory Commission and, in Canada, by Canadian regulators. Also, an excel version, For example, if a subregion decreased dependency on a fossil fuel (e.g., coal, oil, or gas) and replaced it with a renewable source (e.g., nuclear, hydro, biomass, wind, solar, or geothermal), overall CO2emission rates would likely decrease. Available from EPAs eGRID web site:https://www.epa.gov/egrid. . What other emissions data are available from EPA? The Western Interconnection encompasses the area from the Rockies west and consists of 37 balancing authorities: 34 in the United States, 2 in Canada, and 1 in Mexico. This redundancy helps prevent transmission line or power plant failures from causing interruptions in service. This is particularly true for the emission rates by fuel type, such as the emission rates for oil.

A .gov website belongs to an official government organization in the United States. Working with users, owners, and operators of BPS assets; government partners; and other stakeholders and industry participants; the ERO Enterprise pursues its mission of assuring the effective and efficient reduction of risks to the reliability and security of theBPS. These interconnections describe the physical system of the grid. eGRID provides an estimate expressed as a percent of generation for the United States, each NERC interconnection (i.e., Eastern, Western, and ERCOT), Alaska, and Hawaii. State energy information, including overviews, rankings, data, and analyses. 2. Red line path fully loaded in the direction of the arrow How do the historical GGL values compare? The network structure of the interconnections helps maintain the reliability of the power system by providing multiple routes for power to flow and by allowing generators to supply electricity to many load centers. In eGRID2012, the map identified secondary and tertiary subregions; however, starting with eGRID2014, the maps simply indicate areas that fall into more than one eGRID subregion without identifying secondary and tertiary subregions. Alternatively, if a subregion increased the relative proportion of fossil generation, for example, to replace generation from a retired nuclear plant, the emissions rates may increase. U.S. Greenhouse Gas Inventory Reports include inventories of U.S. greenhouse gas emissions and sinks. 503-813-6496. In addition to the data categories identified in the February 18 data request, we propose to direct that NERC and WECC provide: (1) The DCS performance--as described in request (1) in the paragraph above--on a balancing authority basis; and (2) the hourly amount of contingency reserve and the fraction of that contingency reserve that is . The generation data in eGRID are from the Energy Information Administration (EIA), which defines net generation as the total gross generation minus station use (which is the amount of electricity used to operate and maintain the electric power plant). The Greenhouse Gas Reporting Program (GHGRP) requires reporting of greenhouse gas (GHG) data and other relevant information from large GHG emission sources, fuel and industrial gas suppliers, and CO2 injection sites in the United States. Wenn du deine Zustimmung nicht erteilst oder zurckziehst, knnen bestimmte Merkmale und Funktionen beeintrchtigt werden. Renamed Power Control Area file to Balancing Authority file to reflect the terminology currently used by the EIA and NERC. The NERC regions ASCC in Alaska and HICC in Hawaii are no longer included in the EIA-860 Plant file and therefore not included in eGRID2020. Import Transactions are those which show the source as a Balancing Authority outside of WACM and a sink in WACM; excluding network service transactions from designated or non-designated resources. In the United States, electricity is generated in many different ways, with a wide variation in environmental impacts. The changes in the resource mix are often attributed to changes in the number of plants in an eGRID subregion (retirements or additions) or changes to operations at individual plants. Total Existing and Planned Generation Because temperature and seasonal events can radically influence the generation of power and the need and use of resources, various scenarios are assessed. Balancing Authority shall take or be taking the same or substantially similar actions when directing BWP to adjust their generation. the Texas Interconnected System.These three interconnections fall under the authority of the National Energy Regulatory Commission (NERC), an independent organization whose mission is to ensure the reliability of the bulk power system in North America. White zone exactly 15% reserve margin The grid gross loss (GGL) methodology changed, nowexcludes exports. Greenhouse gas data, voluntary reporting, electric power plant emissions. These losses mainly occur from energy dissipated in the conductors, transformers, and other equipment used for transmission, transformation, and distribution of power. It matches generation with load and maintains consistent electric frequency of the grid, even during extreme weather conditions or natural disasters. It looks like your browser does not have JavaScript enabled. The use of one data source minimizes error due to differences in the way EIA and FERC collect data. Hub Map - WECC Power & Gas. Share sensitive information only on official, secure websites. Net imports-exports by state are provided for years 2004, 2005, and 2007. Revised the CHP adjustment calculations to no longer estimate a CHP adjustment ratio for plants where EIA reports the heat input for electricity generation as equal to the total heat input for the plant. Tags: This is the same methodology used in all editions of eGRID. More information about the plant assignment methodology can be found in section 3.4.2 of the Technical Guide. eGRID also provides aggregated data by state, U.S. total, and by three different sets of electric grid boundaries (i.e., balancing authority area, NERC region, and eGRID subregion). As defined in the NERC Glossary. Input emission rates are reported in pounds per million British thermal units (lb/MMBtu). The structure provides flexibility to expand, offers potential cost-saving opportunities by sharing future facility costs, and clarifies roles and responsibilities of the members regarding reliability standard compliance. Greenhouse gas registries and inventories. 44 0 obj <>stream What are the regional emission rates and resource mix? Balancing authority area (generally smaller regions of the power grid in which all power plants are managed to balance power system demand and supply); NERC region, as designated by the North American Electric Reliability Corporation (plus Alaska, Hawaii, and Puerto Rico). The designated reporting contacts should provide requested information to WECC by the established due date and answer any (WECC), handling an estimated 35 percent of the electric load in the west. More >>, Registered Entities: Registered entities are those required by law to register with NERC and comply with NERC Reliability Standards. Reports are published annually, about ten months after year-end. ETC F IS CALCULATED AS FOLLOWS: ETC F = NL F + NITS F + GF F . %%EOF To maintain consistency with other GHG reporting methodologies, eGRID revised the emissions factor starting with eGRID2014. %PDF-1.6 % In some cases, the amount of station use electricity exceeds the total amount of electricity generated at the plant, and the total net generation is a negative number. The machine-readable files are formatted to allow researchers, regulators, and application developers to more easily access and analyze data. 4.1.1. Yes, additional data files are available. Short, timely articles with graphics on energy, facts, issues, and trends. Electricity generation is the dominant industrial source of air emissions in the United States today. the Eastern Interconnected System (from the Atlantic ocean to the Rocky Mountain States), the Western Interconnected System (for States west of the Rocky Mountains), and. EPA aggregates the data and presents it for Alaska, Hawaii, and the Eastern, Western, and ERCOT NERC interconnections.

If a corresponding eGRID data year is not available, it is recommended to use the eGRID version preceding the inventory year. Also, in addition to the code descriptions available in theTechnical Guide, a Fueleconomy.gov, a partnership between EPA and DOE, uses eGRID data to estimate the total GHG emissions from electric and plug-in hybrid vehicles in itsGreenhouse Gas Emissions for Electric and Plug-in Hybrid Electric Vehicles calculator. This change returns the methodology to the approach used in eGRID2012 and previous editions. WECCs predecessor organization, WSCC, was organized in 1967 to facilitate electric industry coordination in the planning and operations of the electric system in Western North America. For example, users can select among wind, solar, and different EE savings options (load impact profiles) within the tool. The national-fuel and state-fuel content average, calculated from EIA-923 Schedule 3A, was updated. Western Interconnection (37 balancing authorities, including 3 in Canada and Mexico) ERCOT (most of Texas - 1 balancing authority - within a single state, so not regulated by the FERC) RTOs (or ISOs) - 7 Regional Transmission Pools with Wholesale Electricity Markets RTO map [ Better map and description ] [ Summary data about each RTO ] For ongoing work, the best practice is to apply the most recent factors available at the time. Similarly, WECCs mission today is to: Northwest Power Pool Area (NWPP) 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. At the highest level, the United States power system in the Lower 48 states is made up of three main interconnections, which operate largely independently from each other with limited transfers of power between them. Nader Samaan. Hydro Quebec TransEnergie. It matches generation with load and maintains consistent electric frequency of the grid, even during extreme weather conditions or natural disasters. Mercury emissions (when available) are included at the unit-level. In addition to the hourly emission data reported to EPA from power plants affected by the Acid Rain Program and/or the Cross-State Air Pollution Rule, the Clean Air Markets website presents progress reports, power plant emission trends, and emissions tracking highlights. document.write(theDate.getFullYear()) (30.37 KB, 1/30/23) Yes, starting with the release of eGRID2012 (October 8, 2015), the naming convention changed. In Ihrem Browser ist Javascript deaktiviert, wird allerdings zur Darstellung unserer Seite bentigt. The preeminent source of air emission data for the electric power sector, eGRID is based on available plant-specific data for all U.S. electricity generating plants that provide power to the electric grid and report data to the U.S. government. Committees and Volunteers: Many members and other bulk power industry experts provide time and expertise to NERC, industry, and the general public by participating in NERC committees, subcommittees, task forces, working groups, and standard drafting teams. The technical storage or access that is used exclusively for anonymous statistical purposes. Advanced filtering capabilities allow viewing the data by fuel type, status, state, zone and more. maintain a reliable bulk electric power system in the Western Interconnection that supports efficient competitive power markets, assure open and non discriminatory transmission access among Members, and. Red zone less than 15% reserve margin More>>, Registered Ballot Body: The Registered Ballot Body, comprised of industry and other interested stakeholders, plays a critical role in the standards development process by voting and offering comments on proposed NERC Reliability Standards. Are EIA-923 data updates reflected in eGRID? Map multiple locations, get transit/walking/driving directions, view live traffic conditions, plan trips, view satellite, aerial and street side imagery. Most, but not all, balancing authorities are electric utilities that have taken on the balancing responsibilities for a specific portion of the power system. An official website of the United States government. If you choose to Reject all, we will not use cookies for these additional purposes. [1] The balancing authorities are connected by metered high-voltage tie lines[2][3] and grouped into interconnections:[4][5], A typical balancing authority is an electric utility with an added responsibility to maintain a fine balance between the production and consumption of electricity, including ensuring availability of sufficient on-line generation resources and managing the electricity transfers from (and to) other balancing authorities. The following citation for eGRID Data is suggested: United States Environmental Protection Agency (EPA). 5. Hovering over an individual subregion brings up a tooltip that displays the data along with a short description of the resource mix change for that individual eGRID subregion. It also provides net generation at the prime mover level for all plants. Die technische Speicherung oder der Zugriff, der ausschlielich zu statistischen Zwecken erfolgt. BAL- 004-WECC-1 required Balancing Authorities within the Western Interconnection to maintain Interconnection frequency within a predefined frequency profile and to ensure that Time. The California ISO's RC West is the Reliability Coordinator (RC) of record for 42 balancing authorities and transmission operators in the western United States. Transmission Service Requests (TSR) Veronica Whitesmith. Wheelmap.org is a community project everyone can get involved. The CH4emissions factors which eGRID uses changed in eGRID2014. The number of boilers at the plant-level is changed to number of units. Revised the plant-to-eGRID subregion assignment methodology to be based on where the plant supplies its electricity, rather than where the plant is physically located. ISNE. that were reported in the Plant file in past editions of eGRID are included as a separate file (discontinued with the release of eGRID2019). The year noted in the title reflects the data year rather than the release year. Why are there outliers for some output emission rates? Westhafen Event & Convention Center. Florida Reliability Coordinating Council, Inc. HQT. AVERT produces outputs including maps, charts, and tables, that display the location of emission reductions at the regional, state, and county level, on a monthly and annual basis. 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. Green zone more than 15% reserve margin WECCs members, representing all segments of the electric industry within the Western Interconnection, provide electricity to 71 million people in 14 western states, two Canadian provinces, and portions of one Mexican state. Power Profiler Emissions Tool (xlsx) One of the most popular recent uses of eGRID is to determine the indirect GHG emissions from electricity purchases and avoided GHG emissions from projects and programs that reduce the demand for grid supplied electricity. In general, the CO2output emission rates for most eGRID subregions increased in 2021 compared to 2020. *Please note that the regional boundaries in the NERC Regions map (also shown above) are approximate. The plant level data are then aggregated to state, U.S. total, and three types of power grid regions:. For example, the 2017 inventory should use eGRID2016. EIA data were allocated to unit level allowing the unit level data sum to equal the plant-level data. While EPAs Greenhouse Gas Reporting Program allows the use of either emissions factor when reporting emissions, the majority of users choose to use the higher emissions factor. See the Compliance Registry page for a list of the approximately 1,400 registered entities. eGRID2014 and subsequent eGRID editions use only EIA data, as well as a new formula (as described above).

Is there additional eGRID data available? The California Independent System Operator (CAISO) is the largest of about 38 balancing authorities in the western interconnection coordinating council (WECC), handling an estimated 35 percent of the electric load in the west. The ERO Enterprise now encompasses six regional organizations of similar size and complexity. Analysts can use these emission factors to compare the emissions impacts of wind, solar, and energy efficiency program impacts. The Balancing Authority of Northern California (BANC) is a Joint Powers Authority (JPA) consisting of the Sacramento Municipal Utility District (SMUD), Modesto Irrigation District (MID), Roseville Electric, Redding Electric Utility (REU), Trinity Public Utility District (TPUD) and the City of Shasta Lake as its founding Members. 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. . If the corrections are deemed to affect the eGRID data significantly, EPA will release another version of eGRID incorporating the latest EIA updates. 503-813-6958. But there are some cases where there are discrepancies between the unit-level and prime mover-level data from EIA. 4.1.1.1. 1752 [10]), and has said that together with . Without a subpoena, voluntary compliance on the part of your Internet Service Provider, or additional records from a third party, information stored or retrieved for this purpose alone cannot usually be used to identify you. It is managed by 37 Balancing Authorities (BAs) of various ownership structures . The A balancing authority ensures, in real time, that power system demand and supply are finely balanced. A Balancing Authority (BA), or Control Area, generally comprised of large and small transmission owners, is the responsible entity that matches loads to resources within the system, maintains scheduled interchange between control areas, maintains frequency within reasonable limits, and provides sufficient generation capacity to maintain operating reserves. How has the methodology for estimating methane (CH. var theDate=new Date() eGRID is most often used to estimate indirect emissions from electricity purchases, in GHG inventories, for carbon footprinting, and for estimating avoided emissions from programs and projects that reduce consumption of grid-supplied electricity.
