Avangrid Prepping to Go Live With Balancing Authority in June British Columbia Hydro and Power Authority. 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 . This change returns the methodology to the approach used in eGRID2012 and previous editions. All rights reserved. Red line path fully loaded in the direction of the arrow 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. The source of these emissions factors is Table C-2 ofEPAs Mandatory Rule on the Reporting of Greenhouse Gases (40 CFR Part 98). Electricity generated at power plants moves through a complex network of electricity substations, power lines, and distribution transformers before it reaches customers. 3.6.3.2 Take all necessary actions, up to and including, shedding of firm load, to alleviate a reliability issue in the Balancing Authority Area.

The Electric Reliability Council of Texas (ERCOT) covers most, but not all, of Texas and consists of a single balancing authority. This is the same methodology used in all editions of eGRID. 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. The plant level data are then aggregated to state, U.S. total, and three types of power grid regions:. [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. Balancing Authority Cooperation Concepts - Intra-Hour Scheduling. Hub Map - WECC Power & Gas. . North American Electric Reliability Corporation, Glossary of Terms Used in Reliability Standards, U.S. electric system is made up of interconnections and balancing authorities, "Balancing Authority and Regulation Overview", https://en.wikipedia.org/w/index.php?title=Balancing_authority&oldid=1125869119. This is due to plants with negative net electricity generation. The output emission rates (e.g. BANC provides reliable grid operation consistent with standards developed and enforced by the Federal Energy Regulatory Commission (FERC), the North American Electric Reliability Corporation (NERC), and the Western Electricity Coordinating Council (WECC). 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 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. 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.

ETC F IS CALCULATED AS FOLLOWS: ETC F = NL F + NITS F + GF F . 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.

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. Use AVERTs web edition or Excel-based tool to create custom calculations that reflect variations in hourly impacts of different EE programs or RE resources within one of AVERTs ten regions. Die technische Speicherung oder der Zugriff, der ausschlielich zu statistischen Zwecken erfolgt. Download allthe current data hereand the historical data here. 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.

It also provides members a unified voice and representation in topics pertaining to Balancing Area matters. 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. 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.

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. Updated the methodology to determine generation and NO. WECC Balancing Authority Areas and subregions. ERO Enterprise | Regional Entities - North American Electric The actual operation of the electric system is managed by entities called balancing authorities. 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. Hub Map - WECC Power & Gas 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. 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. 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 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. Delegates authority to WECC .

A lock (LockA locked padlock) or https:// means youve safely connected to the .gov website. 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. A map of the interconnections is available here. 5. BANC Members contract for about 40% of the CVP hydroelectric resource. EPAs Power Profiler application, which uses eGRID data, helps individual consumers understand the environmental impacts of their own electricity usage. 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". Therefore, directly downloading and using the sub-regional data was not compatible with our method. eGRID2021 is updated with 2021 data and includes the following change to the methodology: Please see the Technical Guide for more details. If a corresponding eGRID data year is not available, it is recommended to use the eGRID version preceding the inventory year. Source publication Impact of Transmission on Resource Adequacy in Systems with Wind and Solar Power Conference Paper Full-text available Jul. All plants in Alaska and Hawaii have been assigned to a NERC region matching their state abbreviation (i.e., AK and HI). Since eGRID2016, plants are assigned to subregions using data from EIA and NERC in a five step process. Please enable scripts and reload this page. 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.
