The boundaries shown on these maps are not based on strict geographical boundaries. 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 Reserve Sharing Group when comprised of a Source Balancing Authority becomes the . Source publication Impact of Transmission on Resource Adequacy in Systems with Wind and Solar Power Conference Paper Full-text available Jul. For a fuel type such as oil, which is the primary fuel type for relatively few plants in each region, negative net generation may have much more of an impact on the emission rates. Reports requested by congress or otherwise deemed important. 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. [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]. Similarly, WECCs mission today is to: Northwest Power Pool Area (NWPP) This is the same methodology used in all editions of eGRID. CH4/GWh) for eGRID2010 and eGRID2012 at the subregion-level and also presents the eGRID2014 CH4 output emission rates for comparison. Wenn du deine Zustimmung nicht erteilst oder zurckziehst, knnen bestimmte Merkmale und Funktionen beeintrchtigt werden. Balancing authorities maintain appropriate operating conditions for the electric system by ensuring that a sufficient supply of electricity is available to serve expected demand, which includes managing transfers of electricity with other balancing authorities. Year-to-year differences in the regional CH4emission rates are explained by changes in each regions resource mix. If there are several plants that report negative net generation, then it can reduce the denominator of that equation and result in a higher overall output emission rate. Yes, additional data files are available. A balancing authority ensures, in real time, that power system demand and supply are finely balanced. The following citation for eGRID Data is suggested: United States Environmental Protection Agency (EPA). If the corrections are deemed to affect the eGRID data significantly, EPA will release another version of eGRID incorporating the latest EIA updates.

A new data source is used to identify the geothermal plant type. Lgcensed under CC BY-SA 3.0 via Wikimedia Commons - . More commonly known as line losses, power losses, or transmission and distribution (T&D) losses, the grid gross loss (GGL) is an estimate of the energy lost in the process of supplying electricity to consumers. eGRID Code Lookup (xlsx) If demand and supply fall out of balance, local or even wide-area blackouts can result. The Eastern Interconnection consists of 36 balancing authorities: 31 in the United States and 5 in Canada. Sales, revenue and prices, power plants, fuel use, stocks, generation, trade, demand & emissions. 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. How do eGRID2021subregion rates compare to eGRID2020? 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. This redundancy helps prevent transmission line or power plant failures from causing interruptions in service. 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. Moved supplemental data such as historical sequence IDs to another spreadsheet. 4.1.1.1. 2013. 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. The source of these emissions factors is Table C-2 ofEPAs Mandatory Rule on the Reporting of Greenhouse Gases (40 CFR Part 98).

[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. 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 . Most carbon footprint calculators that are applicable to the United States use eGRID data. Demographic information from EPA's Environmental Justice Screening and Mapping Tool (EJScreen) is available for each plant in the "DEMO" tab of the spreadsheet. California-Mexico Power Area (CA/MX). %PDF-1.6 % Mercury emissions (when available) are included at the unit-level. Northern Tier Transmission Group. A Consolidated Balancing Authority (CBA) is necessary for an Operating Reserves market to work. The naming convention changed to include the data year in the title (e.g. Many consumers have a choice regarding the source of their electricity, and some seek cleaner sources, such as wind and solar power. 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]. The Emissions & Generation Resource Integrated Database (eGRID) is a comprehensive inventory of environmental attributes of electric power systems. 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. This balance is needed to maintain the safe and reliable operation of the power system. 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. Balancing Authority Cooperation Concepts - Intra-Hour Scheduling. [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. This change returns the methodology to the approach used in eGRID2012 and previous editions.

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). Applicability 4.1. Mass emissions are reported in either pounds or tons. Added non-baseload generation by fuel type and non-baseload resource mix to the subregion file. 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. Most of the eGRID emission data are from the Clean Air Markets Programs of EPA. Veronica.Whitesmith@PacifiCorp.com. WECC Balancing Authority Areas and subregions. 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. 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. British Columbia Hydro and Power Authority. See the Compliance Registry page for a list of the approximately 1,400 registered entities. 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.

ERCOT is unique in that the balancing authority, interconnection, and the regional transmission organization are all the same entity and physical system. The technical storage or access is necessary for the legitimate purpose of storing preferences that are not requested by the subscriber or user. Assignments are based on each plants NERC region, Balancing Authority, and transmission/distribution/utility service territory. Kristopher.Bremer@PacifiCorp.com. In 2015, Executive Order 13693 was issued, requiring Federal agencies to reduce their greenhouse gas emissions from direct and indirect activities. The summary tables for previous years can be found with the historical data. 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. 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". Also, see theNational Emissions Inventories for the U.S.and the Toxics Release Inventory. 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. [ 1] The WEIM's advanced market system automatically finds low-cost energy to serve real-time consumer demand across the west. The Electric Reliability Council of Texas (ERCOT) covers most, but not all, of Texas and consists of a single balancing authority. : For more information click the links inside the Popups, which appear if you hover above a pin within the map.

In many states, power companies are required to disclose the environmental attributes of their retail electricity products. (3.06 MB, 02/15/2023) CAISO manages 80 percent of the load in California and a small portion of Nevada. 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. Sign up for email subcriptions to receive messages about specific EIA products. To maintain consistency with other GHG reporting methodologies, eGRID revised the emissions factor starting with eGRID2014. U.S. Energy Information Administration 1000 Independence Ave., SW Washington, DC 20585. A. 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. For example, the California Air Resources Board, Climate Registry, Climate Action Reserve, and Greenhouse Gas Protocolcite eGRID for use in estimating scope-2 GHG emissions from electricity purchases in the United States. What do the eGRID subregion and NERC region maps look like? A flag identifying plants that contain CAMD-level data has been added to the plant-level spreadsheet. 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 grid gross loss (GGL) methodology changed, nowexcludes exports. Load and resource data submitted by the BA to WECC is used to identify areas that have the potential for electricity supply shortages. 4.2 Reserve Sharing Group 4.2.1. 0 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. [3], A meter on a tie-line is shared between the two BAs interconnected by this line. In the United States, electricity is generated in many different ways, with a wide variation in environmental impacts. 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 formula for calculating GGL remains nearly the same as the previous methodology, with the exception that net interstate exports are subtracted from the total disposition in the denominator. *Please note that the regional boundaries in the NERC Regions map (also shown above) are approximate. 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. [4], Balancing authorities operation is guided by mandatory reliability standards created by the North American Electric Reliability Corporation and approved by the US (Federal Energy Regulatory Commission) and Canadian regulators. All of the regional transmission organizations in the United States also function as balancing authorities. All rights reserved. It also provides members a unified voice and representation in topics pertaining to Balancing Area matters. 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. CO2/MWh) in some eGRID subregions are significantly higher than the rates in other regions. This is particularly true for the emission rates by fuel type, such as the emission rates for oil. A map of the interconnections is available here. In recent years, there have been several changes to the eGRID content, methodology, and presentation of data.
