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.
The spark spread is the theoretical gross margin of a gas-fired power plant from selling a unit of electricity, having bought the fuel required to produce this unit of electricity. All other costs must be covered from the spark spread. The term was first coined by Tony West's trading team on the trading floor of National Power Ltd in Swindon, UK during the late 1990s and quickly came into common usage as other traders realised the trading and hedging opportunities.
A fossil fuel power station is a thermal power station which burns a fossil fuel, such as coal or natural gas, to produce electricity. Fossil fuel power stations have machinery to convert the heat energy of combustion into mechanical energy, which then operates an electrical generator. The prime mover may be a steam turbine, a gas turbine or, in small plants, a reciprocating gas engine. All plants use the energy extracted from the expansion of a hot gas, either steam or combustion gases. Although different energy conversion methods exist, all thermal power station conversion methods have their efficiency limited by the Carnot efficiency and therefore produce waste heat.

Thunder Bay Generating Station is a defunct biomass-fired thermal power station owned by Ontario Power Generation ("OPG"). It is located on Mission Island in Thunder Bay, on the shore of Lake Superior.
Energy in Victoria, Australia is generated using a number of fuels or technologies, including coal, natural gas and renewable energy sources. Brown coal is the main primary energy source for the generation of electricity in the state, accounting for about 85% of electricity generation in 2008. The amount of coal-fired power has decreased significantly with the closure in 2017 of the Hazelwood power station which supplied around 20% of Victoria’s electricity, and to a lesser extent with the exit of Anglesea power station in 2015. Brown coal is one of the largest contributors to Australia's total domestic greenhouse gas emissions and a source of controversy for the country. Australia is one of the highest polluters of greenhouse gas per capita in the world. In 2016, about 16% of Victoria’s electricity was from renewable sources, with a government target to increase that share to 40% by 2025. In 2019, renewable energy provided 23.9% of the state's electricity. On 28 March 2021, Victoria reached 50% renewable energy.
The Presque Isle Power Plant was a coal power plant located at Marquette, Michigan, on the shore of Lake Superior. The plant has 5 inactive generating units with a total net generating capacity of 431 Megawatts. This plant has two smokestacks 400 and 410 feet in height and was built in 1955 by Cleveland-Cliffs Iron Company. Units 1 and 2 were retired on January 1, 2007. Units 3 and 4 were retired on October 1, 2009. Units 5 through 9 went into service between 1975 and 1979 and were retired in March 2019.
Oak Creek Power Plant, also known as South Oak Creek, is a base load, coal- and natural gas-fired, electrical power station located on Lake Michigan in Oak Creek, Wisconsin. Oak Creek Power Plant along with Elm Road Generation Station make up the entire Oak Creek Generating Site.
E. J. Stoneman Generating Station was an electrical power station located in Cassville in Grant County, Wisconsin. It was originally a coal fired facility for several decades and a biomass facility for 5 years.
Edgewater Generating Station is a 380 megawatt (MW) coal power plant located on the south side of Sheboygan, Wisconsin, on the shore of Lake Michigan, whose waters are used to provide cooling. It provides electricity for customers in the northeastern part of Alliant Energy's Wisconsin Power & Light service area and service to several local municipal utilities. In 2009, it was the seventh largest generating station in Wisconsin, with a net summer capacity of 767 MW.
Pleasant Prairie Power Plant was a 1.21-gigawatt coal power plant located in Pleasant Prairie, Wisconsin in Kenosha County. In 2009, it was listed by the U.S. Energy Information Administration (EIA) as the largest generating station in Wisconsin and generated roughly 13% of Wisconsin's electricity, burning around 13,000 tons of coal daily.
J. P. Pulliam Generating Station was an electrical power station powered by sub-bituminous coal, which could also be substituted by natural gas. It was located in Green Bay, Wisconsin in Brown County. The plant was named after the former Wisconsin Public Service Corporation president John Page Pulliam. The plant units were connected to the power grid via 138 kV and 69 kV transmission lines. The remaining coal units on site were decommissioned in 2018 leaving only the natural gas fired P31 unit active at the site.
The Weston Generating Station, also known as the Weston Power Plant, is a base load, coal fired, electrical power station located in the villages of Rothschild and Kronenwetter in Marathon County, Wisconsin, United States. In 2009, it was listed as the fifth largest generating station in Wisconsin, with a net summer capacity of 1,076 MW. It is owned by Wisconsin Public Service, a subsidiary of WEC Energy Group.
Wisconsin Public Service Corporation (WPS) is a utility company headquartered in Green Bay, Wisconsin. The company serves more than 450,000 electric customers and more than 333,000 natural gas customers in 27 counties in eastern, northeastern northern, and central Wisconsin, and a small portion of Michigan's Upper Peninsula.
Carbon capture and storage (CCS) is a technology that can capture carbon dioxide CO2 emissions produced from fossil fuels in electricity, industrial processes which prevents CO2 from entering the atmosphere. Carbon capture and storage is also used to sequester CO2 filtered out of natural gas from certain natural gas fields. While typically the CO2 has no value after being stored, Enhanced Oil Recovery uses CO2 to increase yield from declining oil fields.
H. R. Milner Generating Station is a coal and natural gas-fired power station owned by Maxim Power, located near Grande Cache, Alberta, Canada. H.R. Milner is currently undergoing conversion from coal to natural gas as the power station's fuel source and is expected to be complete by April 2020.
