Electricity generation is the process of generating electric power from sources of primary energy. For utilities in the electric power industry, it is the stage prior to its delivery to end users or its storage.
In electricity generation, a generator is a device that converts motive power or fuel-based power into electric power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even hand cranks. The first electromagnetic generator, the Faraday disk, was invented in 1831 by British scientist Michael Faraday. Generators provide nearly all of the power for electric power grids.
A power station, also referred to as a power plant and sometimes generating station or generating plant, is an industrial facility for the generation of electric power. Power stations are generally connected to an electrical grid.
The utility frequency, (power) line frequency or mains frequency is the nominal frequency of the oscillations of alternating current (AC) in a wide area synchronous grid transmitted from a power station to the end-user. In large parts of the world this is 50 Hz, although in the Americas and parts of Asia it is typically 60 Hz. Current usage by country or region is given in the list of mains electricity by country.
MTU Friedrichshafen GmbH is a German manufacturer of commercial internal combustion engines founded by Wilhelm Maybach and his son Karl Maybach in 1909. Wilhelm Maybach was the technical director of Daimler-Motoren-Gesellschaft (DMG), a predecessor company of the German multinational automotive corporation Daimler AG, until he left in 1907. On 23 March 1909, he founded the new company, Luftfahrzeug-Motorenbau GmbH, with his son Karl Maybach as director. A few years later the company was renamed to Maybach-Motorenbau GmbH, which originally developed and manufactured diesel and petrol engines for Zeppelins, and then railcars. The Maybach Mb.IVa was used in aircraft and airships of World War I.
Navantia is a Spanish state-owned shipbuilding company, which offers its services to both military and civil sectors. It is the fifth-largest shipbuilder in Europe and the ninth-largest in the world with shipyards around the globe. The heir to the segregation of the military assets of the IZAR Group in 2005, Navantia designs, builds and supports all types of surface vessels, submarines and systems. In addition, it is expanding into new markets diversifying its product, such as renewable energy, the offshore industry and all kinds of services that it requires by the naval industry.
In rail transport, head-end power (HEP), also known as electric train supply (ETS), is the electrical power distribution system on a passenger train. The power source, usually a locomotive at the front or 'head' of a train, provides the electricity used for heating, lighting, electrical and other 'hotel' needs. The maritime equivalent is hotel electric power. A successful attempt by the London, Brighton and South Coast Railway in October 1881 to light the passenger cars on the London to Brighton route heralded the beginning of using electricity to light trains in the world.
Larsen & Toubro Ltd, commonly known as L&T, is an Indian multinational conglomerate company, with business interests in engineering, construction, manufacturing, technology, information technology and financial services, headquartered in Mumbai. The company is counted among world's top five construction companies. It was founded by Henning Holck-Larsen and Søren Kristian Toubro, who were two Danish engineers taking refuge in India.
A diesel generator (DG) (also known as a diesel Genset) is the combination of a diesel engine with an electric generator (often an alternator) to generate electrical energy. This is a specific case of engine generator. A diesel compression-ignition engine is usually designed to run on diesel fuel, but some types are adapted for other liquid fuels or natural gas.
Rolls-Royce Power Systems AG is a German company owned by Rolls-Royce Holdings with holdings in engine manufacturing brands and facilities. The company previously traded, from 2006 to 2014, as Tognum AG. Prior to 2006, the core company – MTU Friedrichshafen GmbH – was a constituent of DaimlerChrysler Powersystems Off-Highway.
Wind power has been used as long as humans have put sails into the wind. For more than two millennia wind-powered machines have ground grain and pumped water. Wind power was widely available and not confined to the banks of fast-flowing streams, or later, requiring sources of fuel. Wind-powered pumps drained the polders of the Netherlands, and in arid regions such as the American mid-west or the Australian outback, wind pumps provided water for livestock and steam engines.
An engine–generator is the combination of an electrical generator and an engine mounted together to form a single piece of equipment. This combination is also called an engine–generator set or a gen-set. In many contexts, the engine is taken for granted and the combined unit is simply called a generator. An engine–generator may be a fixed installation, part of a vehicle, or made small enough to be portable.
Stewart & Stevenson is a manufacturer and distributor of products and services for the oil and gas, marine, construction, power generation, transportation, mining and agricultural industries.
A standby generator is a back-up electrical system that operates automatically. Within seconds of a utility outage an automatic transfer switch senses the power loss, commands the generator to start and then transfers the electrical load to the generator. The standby generator begins supplying power to the circuits. After utility power returns, the automatic transfer switch transfers the electrical load back to the utility and signals the standby generator to shut off. It then returns to standby mode where it awaits the next outage. To ensure a proper response to an outage, a standby generator runs weekly self-tests. Most units run on diesel, natural gas, or liquid propane gas.
Shaanxi Diesel Engine Heavy Industry, Co. Ltd. ) of Shaanxi, China is a major producer of diesel-powered electrical generators, high-speed prime movers for large-scale marine applications, and is one of China's key state enterprises for the production of such engines.
The Nigerian National Integrated Power Project (NIPP) was conceived in 2004 when Olusegun Obasanjo was the President of the Federal Government of Nigeria. It was formed to address the issues of insufficient electric power generation and excessive gas flaring from oil exploration in the Niger Delta region. Seven power plants were designed in gas-producing states as part of the project.
An electrical grid is an interconnected network for electricity delivery from producers to consumers. Electrical grids vary in size and can cover whole countries or continents. It consists of:
A powership is a special purpose ship, on which a power plant is installed to serve as a power generation resource.
The Rolls-Royce Marine Olympus is a marine gas turbine based on the Rolls-Royce Olympus aircraft turbojet engine.
Segun Adebutu is a Nigerian businessman, economist and philanthropist. He has business interests in oil and gas, shipping, mining, construction, real estate, agriculture and entertainment. He is the chairman and CEO of Petrolex Oil and Gas, a company presently building the second largest refinery in sub-Saharan Africa.
