    Market Definition

    According to IEA, the natural gas power generation market encompasses the production of electricity through the combustion of natural gas, primarily methane (CH4), which is the largest component of natural gas. Natural gas is a fossil fuel energy source consisting of various hydrocarbons, with methane being the most prevalent. It is easily stored and can be delivered through pipelines or liquefied and transported by ship. Gas-fired power plants are valued for their ability to turn on and off quickly, making them a convenient way to respond to both seasonal and short-term demand fluctuations. Natural gas accounts for about a quarter of global electricity generation and plays a significant role in providing a reliable and flexible power supply.
