North American Power Transmission Grid
The electrical power grid that powers Northern America is not a single grid, but is instead divided into multiple wide area synchronous grids. The Eastern Interconnection and the Western Interconnection are the largest. Three other regions include the Texas Interconnection, the Quebec Interconnection, and the Alaska Interconnection. Each region delivers power at a nominal frequency. The regions are not usually directly connected or synchronized to each other, but there exist some HVDC interconnectors. The Eastern and Western grids are connected with 1.32 GW. History In the United States in the 1920s, utilities formed joint operations to share peak load coverage and backup power. In 1934, with the passage of the Public Utility Holding Company Act (United States), electric utilities were recognized as public goods of importance and were given outlined restrictions and regulatory oversight of their operations. From 1967, the East and West interconnections were directly connected ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greenhouse Gas Emissions
Greenhouse gas emissions from human activities strengthen the greenhouse effect, contributing to climate change. Most is carbon dioxide from burning fossil fuels: coal, oil, and natural gas. The largest emitters include coal in China and large oil and gas companies, many state-owned by OPEC and Russia. Human-caused emissions have increased atmospheric carbon dioxide by about 50% over pre-industrial levels. The growing levels of emissions have varied, but it was consistent among all greenhouse gases (GHG). Emissions in the 2010s averaged 56 billion tons a year, higher than ever before. Electricity generation and transport are major emitters; the largest single source, according to the United States Environmental Protection Agency, is transportation, accounting for 27% of all USA greenhouse gas emissions. Deforestation and other changes in land use also emit carbon dioxide and methane. The largest source of anthropogenic methane emissions is agriculture, closely followed by ...

North American Electric Reliability Corporation
The North American Electric Reliability Corporation (NERC) is a nonprofit corporation based in Atlanta, Georgia, and formed on March 28, 2006, as the successor to the North American Electric Reliability Council (also known as NERC). The original NERC was formed on June 1, 1968, by the electric utility industry to promote the reliability and adequacy of bulk power transmission in the electric utility systems of North America. NERC's mission states that it is to "ensure the reliability of the North American bulk power system." NERC oversees six regional reliability entities and encompasses all of the interconnected power systems of Canada and the contiguous United States, as well as a portion of the Mexican state of Baja California. NERC's major responsibilities include working with all stakeholders to develop standards for power system operation, monitoring and enforcing compliance with those standards, assessing resource adequacy, and providing educational and training resour ...

Regional Reliability Council
In geography, regions, otherwise referred to as zones, lands or territories, are areas that are broadly divided by physical characteristics (physical geography), human impact characteristics (human geography), and the interaction of humanity and the environment (environmental geography). Geographic regions and sub-regions are mostly described by their imprecisely defined, and sometimes transitory boundaries, except in human geography, where jurisdiction areas such as national borders are defined in law. Apart from the global continental regions, there are also hydrospheric and atmospheric regions that cover the oceans, and discrete climates above the land and water masses of the planet. The land and water global regions are divided into subregions geographically bounded by large geological features that influence large-scale ecologies, such as plains and features. As a way of describing spatial areas, the concept of regions is important and widely used among the many branches of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

New York Independent System Operator
New York energy law is the statutory, regulatory, and common law of the state of New York concerning the policy, conservation, taxation, and utilities involved in energy. Secondary sources have also influenced the law of energy in the Empire State. The myriad legal issues concerning hydrofracking in New York has in the 2010s spawned a new body of legal authority with primary authorities such as case law, statutes, and zoning regulations, as well as secondary sources such as law review and newspaper articles, for this rapidly changing field of law. Energy Law (Consolidated Laws) The ''New York Consolidated Laws'' includes a statutory code called the "Energy Law". Under New York law, "energy" and "energy resources" are defined as: The N.Y. Energy Law became effective on July 26, 1976 as Chapter 17-A of the Consolidated Laws. The 1970s was a period of tremendous expansion of both federal and state laws concerning energy. This code is divided into these articles, which are ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
California Independent System Operator
The California Independent System Operator (CAISO) is a non-profit Independent System Operator (ISO) serving California. It oversees the operation of California's bulk electric power system, transmission lines, and electricity market generated and transmitted by its member utilities. The CAISO is one of the largest ISOs in the world, delivering 300 million megawatt-hours of electricity each year and managing about 80% of California's electric flow. History The California Legislature created the CAISO in 1998 as part of the state restructuring of electricity markets. The legislature was responding to Federal Energy Regulatory Commission (FERC) recommendations following the passage of the federal Energy Policy Act of 1992, which removed barriers to competition in the wholesale generation of electricity business. FERC regulates CAISO because interstate transmission lines fall under the jurisdiction of federal commerce laws. Management CAISO's leadership consists of executive ...

Regional Transmission Organization
A regional transmission organization (RTO) in the United States is an electric power transmission system operator (TSO) that coordinates, controls, and monitors a multi-state electric grid. The transfer of electricity between states is considered interstate commerce, and electric grids spanning multiple states are therefore regulated by the Federal Energy Regulatory Commission (FERC). The voluntary creation of RTOs was initiated by FERC Order No. 2000, issued on December 20, 1999. The purpose of the RTO is to promote economic efficiency, reliability, and non-discriminatory practices while reducing government oversight. An independent system operator (ISO) is similarly an organization formed at the recommendation of FERC. In the areas where an ISO is established, it coordinates, controls, and monitors the operation of the electrical power system, usually within a single US state, but sometimes encompassing multiple states. RTOs typically perform the same functions as ISOs but cove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
