Grid Congestion
In power engineering, transmission congestion occurs when overloaded transmission lines in an electrical grid are unable to carry additional electricity flow due to the risk of overheating. During grid congestion, the transmission system operator (TSO) has to direct the providers to adjust their dispatch levels to accommodate the constraint. In an electricity market a power plant may be able to produce electricity at a competitive price but cannot transmit the power to a willing buyer. Congestion increases the electricity prices for some customers. Definitions There is no universally accepted definition of the transmission congestion. Congestion is not an event, so it is frequently not possible to pinpoint its place and time (in this respect it is similar to traffic congestion). Regulators define congestion as a condition that prevents market transactions from being completed, while a transmission system operator sees it as inability to maintain the security of the power system ...

Power Engineering
Power engineering, also called power systems engineering, is a subfield of electrical engineering that deals with the generation, transmission, distribution, and utilization of electric power, and the electrical apparatus connected to such systems. Although much of the field is concerned with the problems of three-phase electric power, three-phase AC power – the standard for large-scale power transmission and distribution across the modern world – a significant fraction of the field is concerned with the conversion between rectifier, AC and DC power and the development of specialized power systems such as those used in aircraft or for electric railway networks. Power engineering draws the majority of its theoretical base from electrical engineering and mechanical engineering. History Pioneering years Electricity became a subject of scientific interest in the late 17th century. Over the next two centuries a number of important discoveries were made including the incandes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Independent System Operator
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 in December 1999. The purpose of the RTO is to promote economic efficiency, reliability, and non-discriminatory practices while reducing government oversight.

ENTSO-E
The European Network of Transmission System Operators for Electricity (ENTSO-E) is an association representing 40 electricity transmission system operators (TSOs) from 36 countries across Europe, thus extending beyond EU borders. It manages the Continental Europe Synchronous Area (CESA). ENTSO-E was established and given legal mandates by the EU's Third Package for the Internal energy market in 2009, which aims at further liberalising the gas and electricity markets in the EU. Page not dated. Ukrainian Ukrenergo became the 40th member of the association on 1January 2024. History On 27 June 2008, 36 European electricity transmission system operators (TSOs) signed a declaration of intent in Prague to create the ENTSO-E. ENTSO-E was established on 19 December 2008 in Brussels by 42 TSOs as a successor of six regional associations of the electricity transmission system operators. ENTSO-E became operational on 1 July 2009. The former associations ETSO, ATSOI, UKTSOA, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Operational Control
Control is a function of management that helps identify errors and take corrective actions. This is done to minimize deviation from standards and ensure that the stated goals of the organization are achieved effectively. According to modern concepts, control is a proactive action; earlier concepts of control were only used when errors were detected. Control in management includes setting standards, measuring actual performance, and taking corrective action in decision making. Definition In 1916, Henri Fayol formulated one of the first definitions of control as it pertains to management: According to E. F. L. Brech: According to Harold Koontz: According to Stafford Beer: Robert J. Mockler presented a more comprehensive definition of managerial control: Control can also be defined as "that function of the system that adjusts operations as needed to achieve the plan, or to maintain variations from system objectives within allowable limits." The control ... [...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. 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 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 managem ...

Tradable Securities
Liquid tradable securities (or LTS) is a generic phrase for a wide range of financial instruments. It often differentiates financial instruments that are easily tradable (or tradeable) as opposed to those that require the permission of the company or a signed document that registers the transfer of securities between two market participants. Another way to look at it is the difference between how a person buys a fund (collective investment scheme) and how they buy a bond or share. Liquid tradable securities come in many forms and with a wide variety of acronyms. These include stocks and bonds as well as exchange-traded funds, exchange traded commodities, exchange-traded notes (including certificates), REITs, as well as most OTC securities. Note that these do not include Swaps or repurchase agreement (repos), which are contractual arrangements and as such are not tradable. This is a wider definition than the definition of transferable securities under MiFID. LTS advantage over c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Watt
The watt (symbol: W) is the unit of Power (physics), power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantification (science), quantify the rate of Work (physics), energy transfer. The watt is named in honor of James Watt (1736–1819), an 18th-century Scottish people, Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own Watt steam engine, steam engine in 1776, which became fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one meter per second against a constant opposing force of one Newton (unit), newton, the rate at which Work (physics), work is done is one watt. \mathrm. In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the vo ...

Economic Dispatch
The merit order is a way of ranking available sources of energy, especially electrical generation, based on ascending order of price (which may reflect the order of their short-run marginal costs of production) and sometimes pollution, together with amount of energy that will be generated. In a centralized management scheme, the ranking is such that those with the lowest marginal costs are the first sources to be brought online to meet demand, and the plants with the highest marginal costs are the last to be brought on line. Dispatching power generation in this way, known as economic dispatch, minimizes the cost of production of electricity. Sometimes generating units must be started out of merit order, due to transmission congestion, system reliability or other reasons. In environmental dispatch, additional considerations concerning reduction of pollution further complicate the power dispatch problem. The basic constraints of the economic dispatch problem remain in place but the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Market Power
In economics, market power refers to the ability of a theory of the firm, firm to influence the price at which it sells a product or service by manipulating either the supply or demand of the product or service to increase economic profit. In other words, market power occurs if a firm does not face a perfectly elastic demand curve and can set its price (P) above marginal cost (MC) without losing revenue. This indicates that the magnitude of market power is associated with the gap between P and MC at a firm's profit maximising level of output. The size of the gap, which encapsulates the firm's level of market dominance, is determined by the residual demand curve's form. A steeper reverse demand indicates higher earnings and more dominance in the market. Such propensities contradict Perfect competition, perfectly competitive markets, where market participants have no market power, P = MC and firms earn zero economic profit. Market participants in perfectly competitive markets are cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Load Pocket
A load pocket is an area of electric grid (typically small) that has limited ability to import electricity due to either very high concentration of demand or insufficient transmission capabilities (transmission congestion) and therefore cannot be entirely provided with power without participation of local electricity generation providers. A typical load pocket includes a major city (e.g., New York City, San Francisco, San Diego in the US). Load pocket's existence usually indicates difficulties with building of either new generation or new transmission, or both due to the area constraints or political pressure and despite the pocket being an attractive place for investment (market congestion pricing strongly incentivizes new generation inside the pocket). The load pockets represent a problem for the Electricity market#Wholesale electricity market, deregulated electricity markets, as in the absence of regulation the captive customers are forced to accept the prices set by the local prov ...
