An explanation of the . Air Trends Reportsare EPA's "report card" on the status of air quality and air pollutant emissions. The source of these emissions factors is Table C-2 ofEPAs Mandatory Rule on the Reporting of Greenhouse Gases (40 CFR Part 98). [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. Canada, electricity, generation, ISO (independent system operator), map, NERC (North American Electric Reliability Corporation), RTO (regional transmission organization), transmission, United States, wholesale power, U.S. Energy Information Administration, 1000 Independence Ave., SW, Washington, DC 20585, Have a question, comment, or suggestion for a future article? For example, users can select among wind, solar, and different EE savings options (load impact profiles) within the tool. [4] The enforcement authority is delegated to regional entities (8 in the US). Covered Data. U.S. Energy Information Administration, 1000 Independence Ave., SW, Washington . GIS shapefiles for the eGRID subregions and NERC regions are available here. 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. If you choose to Accept all, we will also use cookies and data to. Western Electricity Coordinating Council. 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. Similarly, WECCs mission today is to: Northwest Power Pool Area (NWPP) For example, the eGRID file released in 2012 with 2009 data was previously named eGRID2012, using the new naming convention its now called eGRID2009. SEKTOR B, Lagerhalle 1 Westhafenstrae 1. If you choose to Reject all, we will not use cookies for these additional purposes. It looks like your browser does not have JavaScript enabled. The subregion emission rates most accurately represent the actual electricity used by consumers by limiting the import and export of electricity within an aggregated area. eGRID data are cited by many emission inventory and registry protocols, various emission calculation tools and applications, hundreds of academic papers, and consultants; it is used for many research applications and efforts. The U.S. bulk transmission system is a complex network of independently owned and operated power plants and transmission lines. 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. The generation by fuel type in the Plant file is based only on the prime mover-level generation data. As defined in the NERC Rules of Procedure. Synchrophasor Data, Operating Reliability Data, Remedial Action Scheme Data, and Transmission Network Model Data, whether or State energy information, including overviews, rankings, data, and analyses. In recent years, there have been several changes to the eGRID content, methodology, and presentation of data. Beginning with eGRID2014, the data are also presented in metric units and are available in the metric data file. The Western Electricity Coordinating Council (WECC) recently published a report on the resource adequacy for the Western interconnection. Come test out some of the products still in development and let us know what you think! The technical storage or access is necessary for the legitimate purpose of storing preferences that are not requested by the subscriber or user. For a small number of plants, we also use the plants NERC Assessment Area. Power Profiler Emissions Tool (xlsx) Output emission rates are reported pounds per megawatt-hour (lb/MWh). 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. These operators monitor the grid to identify potential problems before a situation becomes critical. To better meet the intent of the subregions while ensuring that new plants can be assigned consistently and that changes in the electrical grid are captured in subsequent eGRID updates, the methodology for assigning plants to eGRID subregions has been revised again. The highlighted areas denote overlap as some load-serving entities participate in one Region while associated transmission owners/operators participate in another. 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. This plant was assigned the CAMX subregion based on its balancing authority, which is the Los Angeles Department of Water and Power. The scenarios are divided into Classes to determine existing generation, fluctuations in generation and demand, the status and effect of planned generation additions, and the status and effect of planned transmission projects. 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. The company has been planning the BAA since at least 2016 (CU No. Added a hyperlinked table of contents and color coding to the data file. Newsroom Site Map Contact NERC Advanced Search Company Overview Committees Governance Key Players . The boundaries shown on these maps are not based on strict geographical boundaries. 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. Assignments are based on each plants NERC region, Balancing Authority, and transmission/distribution/utility service territory. You dont even need to register to map places! 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. Several states have used eGRID to publish state specific emission information or have used eGRID to inform policy decisions.

"Map of USA highlighting Florida". Color coded cross-hatching was added to the subregion map in order to illustrate areas where there are secondary and tertiary service subregions. The map below provides an example of a power flow scenario in the WECC area. eGRID is also used by other Federal Government agencies such as Oak Ridge National Laboratory (ORNL) for their Combined Heat and Power and Emissions Savings Calculator, the National Energy Technology Laboratory (NETL) for their sponsored Distributed National Carbon Sequestration Database and Geographic Information System (NATCARB), and the National Renewable Energy Laboratory (NREL) for their micropower distributed generation optimization model named HOMER. It is also useful to individuals seeking environmental information about the electric power sector in the United States. This redundancy helps prevent transmission line or power plant failures from causing interruptions in service. Lgcensed under CC BY-SA 3.0 via Wikimedia Commons - . 2. Nader Samaan. 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). We also use cookies and data to tailor the experience to be age-appropriate, if relevant. Avangrid Renewables notified FERC on April 12 that it is terminating its wind balancing tariff as it prepares to launch its own generation-only balancing authority area (BAA), expected to be operational on June 1, 2018 [ER18-1358]. 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. The Balancing Authority is the responsible entity unless the Balancing Authority is a member of a Reserve Sharing Group, in which case, the Reserve Sharing Group . Regional Reliability Standard BAL-002-WECC-3 applies to balancing authorities and reserve sharing groups in the Western Interconnection, and it specifies the quantity and types of contingency reserves required to ensure reliability under normal and abnormal conditions. Beginning with eGRID2012, cross-hatching on the map identifies areas where more than one eGRID subregion may apply. Purpose To control Interconnection frequency within defined limits. Emission data from EPA are carefully integrated with generation data from EIA to produce useful values like pounds of emissions per megawatt-hour of electricity generation (lb/MWh), which allows direct comparison of the environmental attributes of electricity generation. theHousehold Greenhouse Gas Emissions Calculator, theGreenhouse Gas Equivalencies Calculator, Greenhouse Gas Emissions for Electric and Plug-in Hybrid Electric Vehicles, Combined Heat and Power and Emissions Savings Calculator, Distributed National Carbon Sequestration Database and Geographic Information System (NATCARB), PJM Interconnections Generation Attribute Tracking System (GATS), EPAs Mandatory Rule on the Reporting of Greenhouse Gases (40 CFR Part 98). Renamed Power Control Area file to Balancing Authority file to reflect the terminology currently used by the EIA and NERC. hb``a``f`` Created: August 29, 2022 California Electric Balancing Authority Areas A balancing authority is responsible for operating a transmission control area. Green line path partially loaded in the direction of the arrow 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). Table C-2 includes an emissions factor of 0.011 kg CH4/mmBtu for coal combustion and in the footnote, the table includes the option of using a lower emission factor of 0.001 kg CH4/mmBtu for coal. For a fuel type such as coal or natural gas, which is the primary fuel type for many plants in each region, negative net generation does not have much impact on the overall emission rate. Wheelmap.org is a community project everyone can get involved. The direct connection to the BAB 100 is connected via the Beusselstrae and into the City via nearby S- and U-Bahn stations. Share sensitive information only on official, secure websites. U.S. Balancing Authority or BA. 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. All plants in Alaska and Hawaii have been assigned to a NERC region matching their state abbreviation (i.e., AK and HI). 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. eGRID2012 includes data for 2012); previous naming conventions listed the year eGRID was released rather than the year of the data used. . Red line path fully loaded in the direction of the arrow Global warming potential (GWP) values are updated to the Fourth IPCC Assessment values.

Because there are some methodological changes in different editions of eGRID from year to year, please use caution when comparing data from different years. In the United States, the power system consists of more than 7,300 power plants, nearly 160,000 miles of high-voltage power lines, and millions of low-voltage power lines and distribution transformers, which connect 145 million customers. Secure .gov websites use HTTPS The CH4emissions factors which eGRID uses changed in eGRID2014. NERC REGIONS NPCC MRO RFC WE-CC SPF' SERC TRE FRCC . Operates PSE's Balancing Authority, Generation, and Transmission functions in a safe, efficient, and reliable manner. Since eGRID2016, plants are assigned to subregions using data from EIA and NERC in a five step process. 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. The designated reporting contacts should provide requested information to WECC by the established due date and answer any Westhafen Event & Convention Center. Also, see theNational Emissions Inventories for the U.S.and the Toxics Release Inventory. Custom analysis using the Excel-based tool can be used for short-term Clean Air Act Plan demonstrations, such as NAAQS SIPS, state-wide EE/RE policies, and multi-state analysis. The Reserve Sharing Group when comprised of a Source Balancing Authority becomes the . This page is not available in other languages. 4.1.1. The "Plant operator name" field is changed to "Plant transmission or distribution system owner name" and the "Utility service territory name" field is changed to "Utility name". . As a result, there are a handful of plants where the total plant-level generation does not equal the sum of the generation by fuel type. Credible Source of Interconnection-Wide Information- WECC provides training, education and information on key functions related to mandatory standards and compliance, as well as data, analysis and studies relating to transmission system planning, and renewable integration. 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. 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). 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.

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 Subsequent editionscontinueto use the same factors as used in eGRID2014. Another example is The University of California, BerkeleysCoolClimate Carbon Footprint Maps. Creation of the BANC as a partnership between public and government entities provides for an alternative platform to other Balancing Authorities like the California Independent System Operator (CAISO). Find local businesses, view maps and get driving directions in Google Maps. For generators where unit-level generation data are not available, the generation is based on prime mover-level generation, distributed to each unit based on proportion of nameplate capacity. eGRID is valuable to those in the Federal Government, state and local governments, non-governmental organizations, companies, and academia. The previous methodology did not account for interstate trade values that were included in total disposition for each state, which ultimately led to a slight double counting of values. Within EPA, eGRID data are used by the following applications and programs:Power Profiler, Center for Corporate Climate Leadership, Portfolio Manager, theHousehold Greenhouse Gas Emissions Calculator, theGreenhouse Gas Equivalencies Calculator, and Power Plants and Neighboring Communities. 21 0 obj <>/Filter/FlateDecode/ID[<5E9D1236E8424D46B52F5FDF827E5406><5E9D1236E8424D46B52F5FDF827E5406>]/Index[7 38]/Info 6 0 R/Length 91/Prev 1419787/Root 8 0 R/Size 45/Type/XRef/W[1 3 1]>>stream For ongoing work, the best practice is to apply the most recent factors available at the time. eGRID2021 is updated with 2021 data and includes the following change to the methodology: Please see the Technical Guide for more details. Added unadjusted heat input for renewable fuels (which is calculated by EIA) to the Plant file. In some cases, plants assigned to a particular eGRID subregion may be located far away from most of the other plants in that subregion. Green zone more than 15% reserve margin For example, the Balancing Authorities actions may include: Analysts can use these emission factors to compare the emissions impacts of wind, solar, and energy efficiency program impacts. The Electric Reliability Council of Texas (ERCOT) covers most, but not all, of Texas and consists of a single balancing authority. eGRID is used by many nongovernmental organizations in their tools and analysis. A Balancing Authority (BA) ensures that at every moment in time, and in plans for future times, there is sufficient generation to reliably supply electricity. The following graph shows the eGRID subregion 2020 and 2021 CO2emission rates and highlights percent differences. endstream endobj startxref 1 of Chelan County CISO - California Independent System Operator DEAA - Arlington Valley, LLC DOPD - PUD No. Generation resource mix, in megawatt-hours and percent. eGRID reports both the total net generation (MWh) and net generation from each fuel type at each plant in the Plant file. BANC contracts with SMUD for operations of the Balancing Authority. Demographic information from EPA's Environmental Justice Screening and Mapping Tool (EJScreen) is available for each plant in the "DEMO" tab of the spreadsheet. If a corresponding eGRID data year is not available, it is recommended to use the eGRID version preceding the inventory year. Renewable energy certificates (RECS) tracking systems, such as ISO-New Englands Generation Information System (GIS) and PJM Interconnections Generation Attribute Tracking System (GATS), use eGRID data. Copyright Year-to-year differences in the regional CH4emission rates are explained by changes in each regions resource mix. G 30j3t/?5\33XR ^ An official website of the United States government. 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.

EPAs Power Profiler application, which uses eGRID data, helps individual consumers understand the environmental impacts of their own electricity usage. WECC Balancing Authority Areas and subregions. (WECC), handling an estimated 35 percent of the electric load in the west. However, the CH4emissions factor for all types of coal has been updated in eGRID2014 and subsequent eGRID editions to 0.011 kg CH4/mmBtu from the previous value of 0.001 kg CH4/mmBtu. The California ISO has finalized agreements with 42 of the balancing authorities and transmission operators in the Western Interconnection to receive reliability coordinator services from ISO's RC West: . The balancing authority data administrators are RC West and Southwest Power Pool (SPP). 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. Therefore, directly downloading and using the sub-regional data was not compatible with our method. Has authority to take independent actions as deemed necessary and as specified in NERC and WECC Standards to fulfill the responsibilities of both Balancing Authority Operator and Transmission Operator. The plant level data are then aggregated to state, U.S. total, and three types of power grid regions:. In general, the CO2output emission rates for most eGRID subregions increased in 2021 compared to 2020. A. 5 Tie Points. For example, the 2017 inventory should use eGRID2016.
