On October 13, 2009, the Tres Amigas SuperStation was announced to connect the Eastern, Western and Texas Interconnections via three 5 GW superconductor links. There are even parts that are about 100 years old. Originally designed to last 50 years, many parts have already surpassed that. It is not tied to the Alaska Interconnection. Here are six reasons all of us should be extremely concerned about our power grid problems: 1. There are six DC ties to the Eastern Interconnection in the US and one in Canada, and there are proposals to add four additional ties. tool: the Breakthrough Energy Grid Modeling Project and its accompanying report, A 2030 United States Macro Grid. Interconnections can be tied to each other via high-voltage direct current power transmission lines ( DC ties) such as the north-south Pacific DC Intertie, or with variable-frequency transformers (VFTs), which permit a controlled flow of energy while also functionally isolating the independent AC frequencies of each side. The Western Interconnection stretches from Western Canada south to Baja California in Mexico, reaching eastward over the Rockies to the Great Plains. The minor interconnections are the Québec Interconnection, the Texas Interconnection, and the Alaska Interconnections.Īll of the electric utilities in the Western Interconnection are electrically tied together during normal system conditions and operate at a synchronized frequency of 60 Hz. The other major wide area synchronous grid is the Eastern Interconnection. EDT (percent change) + - BPAT CISO TVA SWPP SOCO PJM NYIS MISO ISNE FPL ERCO DUK -15 0 15 Source: U.S. The Western Interconnection is a wide area synchronous grid and one of the two major alternating current (AC) power grids in the North American power transmission grid. total, and by sets of electric grid boundaries, including NERC regions and eGRID subregions.The electric power transmission grid of the contiguous United States consists of 120,000 miles (190,000 km) of lines operated by 500 companies. Electric system disturbances occur too quickly to. As the EIA explains, these diversions happen automatically. This means reserve capacity can be diverted from an over-supplied area to one hit by shortages. It also provides aggregated data by state, U.S. As the US electricity usage map shows, the national electricity grid has a number of interconnected supply areas. eGRID is typically used for greenhouse gas registries and inventories, carbon footprints, consumer information disclosure, emission inventories and standards, power market changes, and avoided emission estimate 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.ĮGRID annually updates its emission data and rates for each of its subregions. These topographic maps use the USNG as the grid system.

The US Topo series is provided in GeoPDF format which can be actively used in electronic form with a GPS unit, or printed to hard copy. government.ĮGRID is valuable to users seeking air emission data about the electric power sector in the United States. Geologic Survey (USGS) provides online digital 7.5-minute digital quadrangle maps for the entire country for free. electricity generating plants that provide power to the electric grid and report data to the U.S.

eGRID is based on available data for all U.S. portions of grid regions, States, and Puerto Rico.ĮPA’s Emissions & Generation Resource Integrated Database (eGRID) is the preeminent source of air emission data for the U.S. grid regions’ emission data, EPA provides recent and historic air emissions, including carbon dioxide (CO 2), for U.S.
