The WEIM's advanced market system automatically finds low-cost energy to serve real-time consumer demand across the west. [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]. Balancing Authority or Path Operator Flowgate or Qualifying Path Highest Level Duration Folsom, CA Calgary, AB . Electricity generation is the dominant industrial source of air emissions in the United States today. Balancing Authority Cooperation Concepts - Intra-Hour Scheduling. 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. Since eGRID2016, plants are assigned to subregions using data from EIA and NERC in a five step process. 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 becomes the responsible entity. 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. Covered Data. [ 1] It also provides net generation at the prime mover level for all plants. The generation by fuel type in the Plant file is based only on the prime mover-level generation data. As defined in the NERC Rules of Procedure. Synchrophasor Data, Operating Reliability Data, Remedial Action Scheme Data, and Transmission Network Model Data, whether or To maintain consistency with other GHG reporting methodologies, eGRID revised the emissions factor starting with eGRID2014. For example, if a subregion decreased dependency on a fossil fuel (e.g., coal, oil, or gas) and replaced it with a renewable source (e.g., nuclear, hydro, biomass, wind, solar, or geothermal), overall CO2emission rates would likely decrease.

Beginning with eGRID2012, cross-hatching on the map identifies areas where more than one eGRID subregion may apply. See the Compliance Registry page for a list of the approximately 1,400 registered entities. Red zone less than 15% reserve margin Functional Entities: 4.1.1. Are EIA-923 data updates reflected in eGRID? EIA data were allocated to unit level allowing the unit level data sum to equal the plant-level data. The following citation for eGRID Data is suggested: United States Environmental Protection Agency (EPA). 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). It is characterized by long transmission lines connecting remote generation facilities to load centers. Replaced Boiler file with new Unit file; included the entire universe of units; not just the subset of boilers with unit-level data from EPA/CAMD or EIA. CO2output emission rates may fluctuate on an annual basis due to a change in the resource mix (the percentage of generation from each fuel type). 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.
