	Cogeneration - Wikipedia, the free encyclopedia
		Cogeneration (also combined heat and power or CHP) is the use of a heat engine or a power station to simultaneously generate both electricity and useful heat.
		Cogeneration is thermodynamically the most efficient use of fuel.
		Cogeneration plants are commonly found in district heating systems of big towns, hospitals, prisons, oil refineries, paper mills, wastewater treatment plants, thermal enhanced oil recovery wells and industrial plants with large heating needs.

	cogeneration
		Cogeneration, also known as combined heat and power (cogeneration) or CHP, and total energy, is an efficient, clean, and reliable approach to generating power and thermal energy from a single fuel source.
		One significant impetus for cogeneration is the issue of global climate change from global warming caused by the greenhouse effect, of which fossil fuel combustion is a major contributor.
		Cogeneration technologies are conventional power generation systems with the means to make use of the energy remaining in exhaust gases, cooling systems, or other energy waste stream.

	The Ergosphere: cogeneration@home (Site not responding. Last check: )
		Cogeneration effectively uses fuel energy two or more times: the first time as high-grade (high-temperature, low entropy) heat as input to the engine, and the waste heat is used a second time as lower-grade (lower temperature, higher entropy) heat for other purposes.
		A gas-fired cogenerator with an electric efficiency of 30% and an overall efficiency of 90% will lose 10% of the total energy of the gas, but for each unit of electricity it uses only 1.33 additional units of gas; its effective efficiency is a whopping 75%.
		The cogenerator would produce considerably more electricity than the household could consume, and it seems unlikely that the utility's other customers (who might have their own cogenerators) could be expected to consume it.

	Alcoa: News: What's New at Alcoa - 2006: Cogeneration Power Plant Commissioned for Alcoa Refineries
		The cogeneration unit is one of Western Australia’s most energy efficient power plants, providing electricity into the south-west grid, as well as steam for use in Alcoa’s refinery.
		Cogeneration is a process which produces two outputs – electricity and steam – from the one input (gas).
		The cogeneration plant is more than 75 per cent efficient in converting fuel into electricity, compared with about 30-35 per cent for coal-fired generation and 50 per cent energy efficiency for combined cycle gas turbines.

	Electricity Today Magazine Article -- The Potential For Cogeneration in Ontario's Open Market
		Cogeneration, also known as "combined heat and power" in Europe, is a means of generating heat and electric power at the same time, from the same energy source.
		It was believed that cogeneration would become a popular method of generating electricity, when the market opened in May 2000, since natural gas is the energy choice in the industrial sector (almost double that of electricity).
		Cogeneration plants tend to be smaller than their counterparts and must be built close to the primary user of the electricity.

	What is Cogeneration? (Site not responding. Last check: )
		Cogeneration is a variation of distributed generation, but it is an often misused and misunderstood term.
		Cogeneration is a method by which an energy user can control and reduce energy costs by utilizing the heat that would normally be wasted and use some or all of it for the thermal requirements of a facility.
		Cogeneration is accomplished by utilizing the exhaust gas heat from the internal combustion engine driving the generator (which would normally be lost "up the stack"), the engine cooling jacket water, oil cooling waste heat or a combination of these.

	Cogeneration-Combined Heat and Power (Electricity) Generation (Research Note 21 1998-99)
		Cogeneration or CHP (combined heat and power) is the simultaneous production of electricity and heat using a single fuel such as natural gas, although a variety of fuels can be used (refer to 'Cogeneration capacity by primary fuel').
		The extent to which increases of cogeneration capacity occur in Australia is contingent on addressing market hurdles to the further development of embedded generation, and the recognition of its significantly lower greenhouse gas emissions.
		Where a cogeneration plant is powered by waste gases, especially coal bed methane and methane recovered from landfill sites, then fugitive gases that are naturally escaping into the atmosphere and act as particularly potent greenhouse gases, are captured and utilised to drive gas turbines which in turn generate electricity.

		Cogeneration equipment recaptures the exhaust and water heat of power generation equipment and converts it into hot water, steam, space heat, process heat, air conditioning and many other useful purposes.
		Cogeneration technology provides greater conversion efficiencies than traditional generation methods as it captures heat that would otherwise be wasted.
		Cogeneration systems predominantly use natural gas, a fuel source which emits less than half the greenhouse gas, per unit of energy produced than the cleanest available thermal power station.

	Cogeneration (Site not responding. Last check: )
		Cogeneration units are far more efficient because they recover the ‘waste’ heat from turbines and use it to produce steam.
		With turbine technology, cogeneration is as much as twice as efficient as traditional methods of producing steam in boilers and purchasing electricity from the local power grid.
		Our cogeneration capacity, fueled primarily by clean-burning natural gas, enables a reduction in greenhouse gas emissions of 9 million metric tons per year versus traditional methods.

	Cogeneration solutions from Cummins Power Generation
		Cogeneration, or Combined Heat and Power (CHP), is the production of two kinds of energy -- usually electricity and heat -- from a single source of fuel.
		Cogeneration can replace the traditional method of supplying energy from multiple sources, e.g., purchasing electricity from the power grid and burning natural gas or oil separately in a furnace to produce heat or steam.
		The installation of a 1.75 MW cogeneration system from Cummins Power Generation at the world-famous Chicago Museum of Science and Industry is designed to provide up to 80 percent of the museum's heat, hot water and electricity.

	Cogeneration: Clean, Efficient Energy At Risk
		Neither has a standardized process been established to ensure cogeneration contracts are renewed at reasonable rates, which is of immediate concern since the cogeneration contracts that supply electricity to the state grid will soon expire.
		In response to the energy crisis in the 1970’s, major cogeneration contracts were signed in the 1980’s to increase the efficiency of our energy supply and diversify the state’s portfolio to make it more stable and reliable.
		For years, cogenerators have attempted to renew those contracts but the process has been excruciatingly slow and in many cases unproductive so far because there’s no standardized contracting process and no guarantee the utilities will purchase their electricity.

	NPRA - Cogeneration
		Cogeneration facilities would also be impacted by the legislation developed and introduced to implement the Clear Skies program advocated by the Administration.
		Altering the status of PURPA would jeopardize thousands of megawatts of cogeneration capacity at a time when many regions of the nation are low on electricity and when the federal government is seeking to expand cogeneration capacity.
		Cogeneration units also increase the reliability of the grid, can help bypass transmission system constraints and gain further energy efficiencies by reducing transmission system losses.
