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]. Reports requested by congress or otherwise deemed important. SEKTOR B, Lagerhalle 1 Westhafenstrae 1. Address. If the corrections are deemed to affect the eGRID data significantly, EPA will release another version of eGRID incorporating the latest EIA updates. U.S. [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. It is managed by 37 Balancing Authorities (BAs) of various ownership structures . The technical storage or access that is used exclusively for anonymous statistical purposes. eGRID2014 and subsequent eGRID editions use only EIA data, as well as a new formula (as described above). 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. Applicability 4.1. 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 load-frequency control. Share sensitive information only on official, secure websites. 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. Balancing Authority shall take or be taking the same or substantially similar actions when directing BWP to adjust their generation. Sign up for email subcriptions to receive messages about specific EIA products. Forms EIA uses to collect energy data including descriptions, links to survey instructions, and additional information. 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. Newsroom Site Map Contact NERC Advanced Search Company Overview Committees Governance Key Players . 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. In 2015, Executive Order 13693 was issued, requiring Federal agencies to reduce their greenhouse gas emissions from direct and indirect activities. that were reported in the Plant file in past editions of eGRID are included as a separate file (discontinued with the release of eGRID2019). More >>, Registered Entities: Registered entities are those required by law to register with NERC and comply with NERC Reliability Standards. CAISO manages 80 percent of the load in California and a small portion of Nevada. 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 4.

[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. 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 Load and resource data submitted by the BA to WECC is used to identify areas that have the potential for electricity supply shortages. The year noted in the title reflects the data year rather than the release year. This is the same methodology used in all editions of eGRID. 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. WECC Balancing Authority Areas and subregions. If a Balancing Authority does not have the necessary reserves, they will need to import from a neighboring Balancing Authority or increase the resources available to meet the demand. The total plant-level net generation in the Plant file is the sum of net generation at each plant from the Generator file. Financial market analysis and financial data for major energy companies. How do the historical GGL values compare? By documenting the environmental attributes of electric power generation, eGRID can help consumers and researchers to better understand the relationship between electricity and the environment. Because there are some methodological changes in different editions of eGRID from year to year, please use caution when comparing data from different years. (3.06 MB, 02/15/2023) [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. hb``a``f`` 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. 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. International energy information, including overviews, rankings, data, and analyses. The Eastern Interconnection encompasses the area east of the Rocky Mountains and a portion of northern Texas. Quick Guide PDF 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. Balancing Authority or BA. The COTP is jointly owned by several parties, including WAPA and BANC Members, via the Transmission Agency of Northern California. Lgcensed under CC BY-SA 3.0 via Wikimedia Commons - . 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. The Western Electricity Coordinating Council (WECC) recently published a report on the resource adequacy for the Western interconnection. We make sure the right amount of electricity is generated and transmitted to our member utilities who are then responsible for delivering the power to their . In many states, power companies are required to disclose the environmental attributes of their retail electricity products. 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. But there are some cases where there are discrepancies between the unit-level and prime mover-level data from EIA. . Fueleconomy.gov, a partnership between EPA and DOE, uses eGRID data to estimate the total GHG emissions from electric and plug-in hybrid vehicles in itsGreenhouse Gas Emissions for Electric and Plug-in Hybrid Electric Vehicles calculator. And while NERC and the Regional Entities play different roles in delivering ERO Enterprise programs, these roles are equally important and complementary, allowing the ERO Enterprise to work as one synchronous machineeffectively, efficiently, and collaboratively. The technical storage or access is necessary for the legitimate purpose of storing preferences that are not requested by the subscriber or user. These include: 4 Traded Hubs (PV, SP, NP, MidC) 30 Load Serving Balancing Authoritites. 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. There are a few cases where the emissions rates decreased. 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. These operators monitor the grid to identify potential problems before a situation becomes critical. It is also useful to individuals seeking environmental information about the electric power sector in the United States. 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. If you choose to Accept all, we will also use cookies and data to. 4.1. If a corresponding eGRID data year is not available, it is recommended to use the eGRID version preceding the inventory year.

Added a hyperlinked table of contents and color coding to the data file. ERCOT. Electricity generation is the dominant industrial source of air emissions in the United States today. 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 plant level data are then aggregated to state, U.S. total, and three types of power grid regions:. 2023. System Map This map displays up-to-date information on queues and generation deactivations across the PJM footprint. 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. document.write(theDate.getFullYear()) Transmission Service Requests (TSR) Veronica Whitesmith. In the United States, electricity is generated in many different ways, with a wide variation in environmental impacts. This page is not available in other languages. The U.S. bulk transmission system is a complex network of independently owned and operated power plants and transmission lines. Demographic information from EPA's Environmental Justice Screening and Mapping Tool (EJScreen) is available for each plant in the "DEMO" tab of the spreadsheet. A. It matches generation with load and maintains consistent electric frequency of the grid, even during extreme weather conditions or natural disasters. 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 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. Secure .gov websites use HTTPS A balancing authority is responsible for operating a transmission control area. Estimates of GGL from eGRID2012 and earlier used a different formula based on data on generation, imports, and exports from FERC and consumption data from EIA. Also, an excel version, 1 of Chelan County CISO - California Independent System Operator DEAA - Arlington Valley, LLC DOPD - PUD No. Fuel specific output emission rates (lb/MWh) for CH. Revised the plant-to-eGRID subregion assignment methodology to be based on where the plant is located rather than where it supplies its electricity (revised again in eGRID2016). As defined in the NERC Glossary. Monthly and yearly energy forecasts, analysis of energy topics, financial analysis, congressional reports. 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. System Operator Certification and Credential Maintenance Program provides oversight to the policies and processes used to implement and maintain the integrity and independence of the NERC System Operator Certification Program and is responsible for developing and maintaining the Credential Maintenance Program. The grid gross loss (GGL) methodology changed, nowexcludes exports. Images, shapefiles, and geodatabasesfor are available here. 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. Balancing Authority or Path Operator Flowgate or Qualifying Path Highest Level Duration Folsom, CA Calgary, AB .
