SEKTOR B, Lagerhalle 1 Westhafenstrae 1. 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. Die technische Speicherung oder der Zugriff, der ausschlielich zu statistischen Zwecken erfolgt. Also, see theNational Emissions Inventories for the U.S.and the Toxics Release Inventory. In some cases, plants assigned to a particular eGRID subregion may be located far away from most of the other plants in that subregion. For example, the eGRID file released in 2012 with 2009 data was previously named eGRID2012, using the new naming convention its now called eGRID2009. Balancing Authority or Path Operator Flowgate or Qualifying Path Highest Level Duration Folsom, CA Calgary, AB . Transmission Service Requests (TSR) Veronica Whitesmith. 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. The significant changes starting with the release of eGRID2012 include: More information about each of these changes can be found in the Whats New sections of the Technical Guide (formerly called Technical Support Document)available with each eGRID release. 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. Several states have used eGRID to publish state specific emission information or have used eGRID to inform policy decisions. Electric Reliability Council of Texas, Inc. FRCC. Fuel specific nonbaseload generationis added to the State, BA, NERC region, and US levels. the Eastern Interconnected System (from the Atlantic ocean to the Rocky Mountain States), the Western Interconnected System (for States west of the Rocky Mountains), and. Send your feedback to, Residential Energy Consumption Survey (RECS), Commercial Buildings Energy Consumption Survey (CBECS). The COTP is jointly owned by several parties, including WAPA and BANC Members, via the Transmission Agency of Northern California. Output emission rates are reported pounds per megawatt-hour (lb/MWh). This change returns the methodology to the approach used in eGRID2012 and previous editions. The actual operation of the electric system is managed by entities called balancing authorities. EIA data were allocated to unit level allowing the unit level data sum to equal the plant-level data. Included entire universe of plants and associated generators, including plants with zero generation, which had been excluded from previous editions of eGRID. Share sensitive information only on official, secure websites. Many consumers have a choice regarding the source of their electricity, and some seek cleaner sources, such as wind and solar power.

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. 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. Typically, EIA will make corrections to previously issued EIA-923 data. Another example is The University of California, BerkeleysCoolClimate Carbon Footprint Maps. eGRID data are cited by many emission inventory and registry protocols, various emission calculation tools and applications, hundreds of academic papers, and consultants; it is used for many research applications and efforts. These operators monitor the grid to identify potential problems before a situation becomes critical. provide a forum for resolving transmission access disputes between Members consistent with FERC policies. Copyright 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. *This link leads to the machine-readable files that are made available in response to the federal Transparency in Coverage Rule and includes negotiated service rates and out-of-network allowed amounts between health plans and healthcare providers. 5. It matches generation with load and maintains consistent electric frequency of the grid, even during extreme weather conditions or natural disasters. ERCOT is unique in that the balancing authority, interconnection, and the regional transmission organization are all the same entity and physical system. 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 generation data in eGRID are from the Energy Information Administration (EIA), which defines net generation as the total gross generation minus station use (which is the amount of electricity used to operate and maintain the electric power plant). BAL- 004-WECC-1 required Balancing Authorities within the Western Interconnection to maintain Interconnection frequency within a predefined frequency profile and to ensure that Time. The Council develops a plan, updated every five years, to ensure the region's power supply and acquire cost-effective energy efficiency.
