503-813-6496. The Western Interconnection covers more than 1.8 million square miles and stretches from Western Canada south to Baja California in Mexico and eastward over the Rocky Mountains to the Great Plains to serve more than 80 million customers. WECC Daily Status Report 2023-04-27 Author: Paull, Evan Last modified by: Paull, Evan Created Date: 4/27/2023 12:57:31 PM Other titles: Sheet1 Map . PDF Western Area Power Administration -Rocky Mountain Region The U.S. bulk transmission system is a complex network of independently owned and operated power plants and transmission lines. The Eastern Interconnection encompasses the area east of the Rocky Mountains and a portion of northern Texas. 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. These data are combined at the plant level. Hub Map - WECC Power & Gas States and local governments rely on eGRID data for electricity labeling (environmental disclosure programs), emission inventories, and registries as well as for efforts to analyze air emissions from the electric power sector. 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 . Applicability 4.1. 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 total plant-level net generation in the Plant file is the sum of net generation at each plant from the Generator file. A balancing authority ensures, in real time, that power system demand and supply are finely balanced. 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. Delegates authority to WECC . It also provides net generation at the prime mover level for all plants. ERO Enterprise | Regional Entities - North American Electric A lock (LockA locked padlock) or https:// means youve safely connected to the .gov website. WECC Balancing Authority Areas and subregions. On the Maps webpage, images are available for the eGRID Subregion Map and the NERC Region Map, additionally, an eGRID shapefile and geodatabase are available. * The 2010 and 2012 CH4 emission rates are recalculated using 0.011 kg CH4/mmBtu emissions factors for coal combustion. Is there additional eGRID data available? In 2017, EPA published the first set of AVERT-generated regional and national emission factors. [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. U.S. Energy Information Administration 1000 Independence Ave., SW Washington, DC 20585. Beginning with eGRID2014, the data are also presented in metric units and are available in the metric data file. Images, shapefiles, and geodatabasesfor are available here. AVA Avista AVRN Avangrid AZPS Arizona Public Service BANC Balancing Authority of Northern California Tri-State Generation and . [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].

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. There are a few cases where the emissions rates decreased. 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 subregion emission rates most accurately represent the actual electricity used by consumers by limiting the import and export of electricity within an aggregated area. PDF 2022 Loads and Resources Data Collection Manual - NorthernGrid Why are there outliers for some output emission rates? Send your feedback to, Residential Energy Consumption Survey (RECS), Commercial Buildings Energy Consumption Survey (CBECS). Identified data sources at a more granular level. 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 . 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. Reports requested by congress or otherwise deemed important. Address. Additionally, if you have questions or comments, you can submit them through this web form or email EPA directly. eGRID2021 is updated with 2021 data and includes the following change to the methodology: Please see the Technical Guide for more details. If you choose to Reject all, we will not use cookies for these additional purposes. Many consumers have a choice regarding the source of their electricity, and some seek cleaner sources, such as wind and solar power. Balancing Authority Cooperation Concepts - Intra-Hour Scheduling. . 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. Updated the methodology to determine generation and NO. The generation by fuel type in the Plant file is based only on the prime mover-level generation data. Come test out some of the products still in development and let us know what you think! This change returns the methodology to the approach used in eGRID2012 and previous editions. Synchrophasor Data, Operating Reliability Data, Remedial Action Scheme Data, and Transmission Network Model Data, whether or Please click here to see any active alerts. 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. All units that have a "proposed" status and/or units that retired prior to data year 2021 are no longer included in the eGRID data beginning with eGRID2021.
