The Danskin Power Plant is a gas-fired power plant owned and operated by Idaho Power. The plant is housed in the Evander Andrews Complex near Mountain Home, Idaho, United States.
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 expanding gas, either steam or combustion gases. Although different energy conversion methods exist, all thermal power station conversion methods have efficiency limited by the Carnot efficiency and therefore produce waste heat.

Idaho is a state in the northwestern region of the United States. It borders the state of Montana to the east and northeast, Wyoming to the east, Nevada and Utah to the south, and Washington and Oregon to the west. To the north, it shares a small portion of the Canadian border with the province of British Columbia. With a population of approximately 1.7 million and an area of 83,569 square miles (216,440 km2), Idaho is the 14th largest, the 12th least populous and the 7th least densely populated of the 50 U.S. states. The state's capital and largest city is Boise.
The 261-megawatt plant consists of one 171-MW simple cycle combustion turbine, which came online in May 2008. [1]
A gas turbine, also called a combustion turbine, is a type of continuous combustion, internal combustion engine. The main elements common to all gas turbine engines are:
- An upstream rotating gas compressor;
- A combustor;
- A downstream turbine on the same shaft as the compressor.
The first generating units on the site were two Westinghouse W251 simple cycle turbines which were commissioned in September 2001.
Government agencies believe Danskin Power Plant may have negative impacts on the surrounding environment. [2]
A jet engine is a type of reaction engine discharging a fast-moving jet that generates thrust by jet propulsion. This broad definition includes airbreathing jet engines. In general, jet engines are combustion engines.
A steam turbine is a device that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Sir Charles Parsons in 1884.
In electric power generation a combined cycle power plant is an assembly of heat engines that work in tandem from the same source of heat, converting it into mechanical energy, which in turn usually drives electrical generators. The principle is that after completing its cycle, the temperature of the working fluid in the system is still high enough that a second subsequent heat engine extracts energy from the heat that the first engine produced. By combining these multiple streams of work upon a single mechanical shaft turning an electric generator, the overall net efficiency of the system may be increased by 50–60%. That is, from an overall efficiency of say 34%, to possibly an overall efficiency of 62%, 84% Theoretical efficiency
The Rankine cycle is a model used to predict the performance of steam turbine systems. It was also used to study the performance of reciprocating steam engines. The Rankine cycle is an idealized thermodynamic cycle of a heat engine that converts heat into mechanical work while undergoing phase change. It is an idealized cycle in which friction losses in each of the four components are neglected. The heat is supplied externally to a closed loop, which usually uses water as the working fluid. It is named after William John Macquorn Rankine, a Scottish polymath and Glasgow University professor.
Cogeneration or combined heat and power (CHP) is the use of a heat engine or power station to generate electricity and useful heat at the same time. Trigeneration or combined cooling, heat and power (CCHP) refers to the simultaneous generation of electricity and useful heating and cooling from the combustion of a fuel or a solar heat collector. The terms cogeneration and trigeneration can be also applied to the power systems generating simultaneously electricity, heat, and industrial chemicals – e.g., syngas or pure hydrogen.

The company has a 6,000-square-mile (16,000 km2) electric and natural gas service area.
The BORAX Experiments were a series of safety experiments on boiling water nuclear reactors conducted by Argonne National Laboratory in the 1950s and 1960s at the National Reactor Testing Station in eastern Idaho. They were performed using the five BORAX reactors that were designed and built by Argonne. BORAX-III was the first nuclear reactor to supply electrical power to the grid in the United States in 1955.
Peaking power plants, also known as peaker plants, and occasionally just "peakers", are power plants that generally run only when there is a high demand, known as peak demand, for electricity. Because they supply power only occasionally, the power supplied commands a much higher price per kilowatt hour than base load power. Peak load power plants are dispatched in combination with base load power plants, which supply a dependable and consistent amount of electricity, to meet the minimum demand.
A thermal power station is a power station in which heat energy is converted to electric power. In most of the places in the world the turbine is steam-driven. Water is heated, turns into steam and spins a steam turbine which drives an electrical generator. After it passes through the turbine, the steam is condensed in a condenser and recycled to where it was heated; this is known as a Rankine cycle. The greatest variation in the design of thermal power stations is due to the different heat sources; fossil fuel dominates here, although nuclear heat energy; solar heat energy, biofuels and waste incineration are also used. Some prefer to use the term energy center because such facilities convert forms of heat energy into electrical energy. Certain thermal power stations are also designed to produce heat energy for industrial purposes, or district heating, or desalination of water, in addition to generating electrical power.
An integrated gasification combined cycle (IGCC) is a technology that uses a high pressure gasifier to turn coal and other carbon based fuels into pressurized gas—synthesis gas (syngas). It can then remove impurities from the syngas prior to the power generation cycle. Some of these pollutants, such as sulfur, can be turned into re-usable byproducts through the Claus process. This results in lower emissions of sulfur dioxide, particulates, mercury, and in some cases carbon dioxide. With additional process equipment, a water-gas shift reaction can increase gasification efficiency and reduce carbon monoxide emissions by converting it to carbon dioxide. The resulting carbon dioxide from the shift reaction can be separated, compressed, and stored through sequestration. Excess heat from the primary combustion and syngas fired generation is then passed to a steam cycle, similar to a combined cycle gas turbine. This process results in improved thermodynamic efficiency compared to conventional pulverized coal combustion.
The Experimental Beryllium Oxide Reactor (EBOR) was a 10MWt helium cooled beryllium moderated nuclear reactor at Idaho National Laboratory. It never achieved criticality. The project started on February 17, 1958 as the Maritime Gas-Cooled Reactor. The project started with a contract between the U.S. Atomic Energy Commission and General Dynamics. The Goal of the project was to create a small nuclear reactor for use in merchant shipping or in a medium sized power plant. The main goals for the reactor were a simple design, low maintenance costs and maximum efficiency over a wide range of power settings. In December 1960 the project was authorized to construct a 10-Mw test reactor to determine the characteristics of the Beryllium Oxide gas cooled system. The EBOR was designed to test the basic fuel element and moderator designs for the final reactor. The EBOR used a Helium cooling system and was an intermediate step towards a prototype power plant. The plan was to use a closed cycle turbine or a steam cycle with the reactor to make a small land based or maritime power plant. This plan was abandoned as the reactor never achieved criticality.
A Simple-Cycle Combustion Turbine (SCCT) is a type of gas turbine most frequently used in the power generation, aviation, and oil and gas industry. The simple-cycle combustion turbine follows the Brayton Cycle and differs from a combined cycle operation in that it has only one power cycle.
Mid-Georgia Cogen is a 308 MW electric combined cycle gas turbine power plant located in Kathleen, Georgia.
Repowering is the process of replacing older power stations with newer ones that either have a greater nameplate capacity or more efficiency which results in a net increase of power generated. Repowering can happen in several different ways. It can be as small as switching out and replacing a boiler, to as large as replacing the entire system to create a more powerful system entirely. There are many upsides to repowering. The simple act of refurbishing the old with the new is in itself beneficial alongside the cost reduction for keeping the plant running. With less costs and a higher energy output, the process is excessively beneficial.

A closed-cycle gas turbine is a turbine that uses a gas for the working fluid as part of a closed thermodynamic system. Heat is supplied from an external source. Such recirculating turbines follow the Brayton cycle.
The Kelanitissa Power Station is a state-owned power station located on the south bank of the Kelani River in the northern part of the city of Colombo, Sri Lanka. Commissioned in 1964, it is the first thermal power station built in Sri Lanka, after the country gained independence. The facility has a current gross installed capacity of 360 MW, a significant amount when compared to the total installed capacity of nearly 4,086 MW in the year 2017. The facility is owned and operated by the Ceylon Electricity Board.
