What do the eGRID subregion and NERC region maps look like? [ 1] 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. Electric Reliability Council of Texas, Inc. FRCC. RC West. Air Trends Reportsare EPA's "report card" on the status of air quality and air pollutant emissions. The Electric Reliability Council of Texas (ERCOT) covers most, but not all, of Texas and consists of a single balancing authority. This page was last edited on 6 December 2022, at 08:45. An official website of the United States government. 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. While the majority of zip codes are located within only one eGRID subregion, in some cases a zip code may fall in multiple eGRID subregions because it is supplied by different service providers associated with different subregions. Balancing Authority 4.1.1 A Balancing Authority receiving Overlap Regulation Service is not subject to Control Performance Standard 1 (CPS1) or Balancing Authority ACE Limit (BAAL) compliance evaluation 4.1.2 A Balancing Authority that is a member of a Regulation Reserve Sharing Group is the Responsible . For ongoing work, the best practice is to apply the most recent factors available at the time. Comprehensive data summaries, comparisons, analysis, and projections integrated across all energy sources. Information about the wheelchair accessibility of stations, parking spaces and petrol stations are marked on the map. The map also shows the location of substations, transmission lines and transmission zones. If you are interested in receiving email alerts when eGRID is updated or eGRID related news is released, sign up ateGRID Notification form. 1899 Hoffenheim (Wirsol Rhein-Neckar-Arena). 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. California-Mexico Power Area (CA/MX). 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. The COTP is jointly owned by several parties, including WAPA and BANC Members, via the Transmission Agency of Northern California. [6] The quantitative estimate of the balancing is provided through area control error (ACE, measured in MW[10]),[7] that as an indicator is conceptually similar to the role the frequency deviation plays at the interconnection level: positive ACE is pushing interconnection frequency higher.[11]. How has the methodology for assigning plants to eGRID subregions changed? A Consolidated Balancing Authority (CBA) is necessary for an Operating Reserves market to work. Also, an excel version, Covered Data. The control is maintained by multiple means: direct control of the generators by the computer systems, dispatch orders to power plants communicated by phone, load shedding in emergencies, and exchanging the electricity with other BAs.[15]. BANC is the third largest Balancing Authority in California and the 16th largest Balancing Authority within the WECC area. 2013. 1 of Chelan County CISO - California Independent System Operator DEAA - Arlington Valley, LLC DOPD - PUD No. 3. The net generation in the Generator fileis based on unit-level generation data whereavailable. eGRID is valuable to those in the Federal Government, state and local governments, non-governmental organizations, companies, and academia. eGRID Code Lookup (xlsx) Proposed regional Reliability Standard BAL-002-WECC-3 applies to balancing authorities and reserve sharing groups in the WECC Region, and it specifies the quantity and types of contingency reserve required to ensure reliability under normal and abnormal conditions. Global warming potential (GWP) values are updated to the Fourth IPCC Assessment values. Data on net imports-exports by state and power interchange between grid regions are included in eGRID data for years 1996 through 2000. 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.

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. . hbbd```b```RD L$m r7Hb\@@?|# h49@x5@ uK5 4.1.1.1. 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. [7] Frequently the same utility plays multiple roles, for example, CAISO, in addition to being an independent system operator, is also operating under the name RC West as a reliability coordinator for 42 balancing authorities and transmission operators in the Western interconnection. The loss responsibility falls on the last TSP identified in the e-tag. [6] To coordinate activities across multiple BAs, a reliability coordinator entity (RC) is used that has the power to reduce or cancel the interchange transactions and adjust the dispatch plans. Includes hydropower, solar, wind, geothermal, biomass and ethanol. Generation resource mix, in megawatt-hours and percent. The plant level data are then aggregated to state, U.S. total, and three types of power grid regions:. All plants in Alaska and Hawaii have been assigned to a NERC region matching their state abbreviation (i.e., AK and HI). Find local businesses, view maps and get driving directions in Google Maps. For example, the Balancing Authorities actions may include: U.S. Energy Information Administration, 1000 Independence Ave., SW, Washington . Lgcensed under CC BY-SA 3.0 via Wikimedia Commons - . Added non-baseload generation by fuel type and non-baseload resource mix to the subregion file. In eGRID2012 and previous editions, plants were assigned to eGRID subregions based on a variety of factors, including associated NERC region, Power Control Area (PCA), and transmission/distribution/utility service territory. 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. For a relatively small number of plants (less than 0.1%), the sum of the generation by fuel type does not equal the total net generation at the plant. Crude oil, gasoline, heating oil, diesel, propane, and other liquids including biofuels and natural gas liquids. Information about the wheelchair accessibility of stations, parking spaces and petrol stations are marked on the map . 4.1.1. EPA aggregates the data and presents it for Alaska, Hawaii, and the Eastern, Western, and ERCOT NERC interconnections. Subsequent editionscontinueto use the same factors as used in eGRID2014. Track outages and protect against spam, fraud, and abuse, Measure audience engagement and site statistics to understand how our services are used and enhance the quality of those services, Deliver and measure the effectiveness of ads, Show personalized content, depending on your settings, Show personalized ads, depending on your settings. It matches generation with load and maintains consistent electric frequency of the grid, even during extreme weather conditions or natural disasters. U.S. The methodology was revised in eGRID2014 because information about some of these linkages was no longer available and in an effort to make the process for assigning plants to subregions more straightforward, reproducible, and transparent. (30.37 KB, 1/30/23) If you live in an area with multiple electric service providers (illustrated by cross-hatching on the map), the map isnt sufficient to tell you the eGRID subregion associated with your location. Maps NERC Interconnections NERC Regions Map* NERC Balancing Authority Areas (As of October 2019) NERC Assessment Areas (as of July 2019) *Please note that the regional boundaries in the NERC Regions map (also shown above) are approximate. Demographic information from EPA's Environmental Justice Screening and Mapping Tool (EJScreen) is available for each plant in the "DEMO" tab of the spreadsheet. Exploration and reserves, storage, imports and exports, production, prices, sales. This is due to plants with negative net electricity generation. 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 . For this information, you must enter your zip code and electric service provider information intoPower Profilerto definitively determine your appropriate eGRID subregion. 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. Select More options to see additional information, including details about managing your privacy settings. Because there are some methodological changes in different editions of eGRID from year to year, please use caution when comparing data from different years. 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. endstream endobj startxref The balancing authority data administrators are RC West and Southwest Power Pool (SPP). The grid gross loss (GGL) methodology changed, nowexcludes exports. It also provides members a unified voice and representation in topics pertaining to Balancing Area matters. This change returns the methodology to the approach used in eGRID2012 and previous editions.

Local electricity grids are interconnected to form larger networks for reliability and commercial purposes. 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. Ansergy forecasts hourly prices for 48 WECC price points. eGRID2012 includes data for 2012); previous naming conventions listed the year eGRID was released rather than the year of the data used. 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. To align more closely with estimates made by EIA, starting with the release of eGRID2018, the methodology for calculating GGL changedslightly from the previous methodology used to create GGL values for eGRID2014 and eGRID2016. 7 0 obj <> endobj It matches generation with load and maintains consistent electric frequency of the grid, even during extreme weather conditions or natural disasters. eGRID data can be used to support the following activities: For virtually every grid-connected power plant in the United States, eGRID provides: eGRID provides separate data at the combustion unit and generator levels. 5 Tie Points. 4.1 Balancing Authority 5. [9], A balancing authority has the following responsibilities:[6], The coordination tasks are performed by the balancing authority staff and the automatic generation control (AGC) systems. Yes, starting with the release of eGRID2012 (October 8, 2015), the naming convention changed. The entity that is the highest level of authority who is responsible for the Reliable Operation of the Bulk Electric System, has the Wide Area view of the Bulk Electric System, and has the operating tools, processes and procedures, including the authority to prevent or mitigate emergency operating situations in both next-day analysis and real-time operations.Read more These losses mainly occur from energy dissipated in the conductors, transformers, and other equipment used for transmission, transformation, and distribution of power. In eGRID2014, plants were assigned to eGRID subregions by first using the NERC region and then, for the remaining plants, using GIS shapefiles based on a plants physical location. It is managed by 37 Balancing Authorities (BAs) of various ownership structures . 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. Several states have used eGRID to publish state specific emission information or have used eGRID to inform policy decisions. Most of the eGRID emission data are from the Clean Air Markets Programs of EPA. Hydro Quebec TransEnergie. Maps, tools, and resources related to energy disruptions and infrastructure. This page is not available in other languages. Power Supply Adequacy Consistent with the requirement to maintain operating reserves as defined by WECC and NERC operating policies, WECC conducts, on a seasonal basis, an assessment of generating reserve margins and transmission limitations between load and resource areas as well as probabilities of supplying expected load levels, accounting for uncertainties. For example, the Intermountain Power Project plant is assigned to the CAMX subregion, yet this plant is located in Utah. 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. The year noted in the title reflects the data year rather than the release year. Green zone more than 15% reserve margin WECC is a conduit for other data exchanges. EIA provides net generation at the unit level for a subset of plants in the United States.
