Union Power Station2,428 MW Gas

Gas

The Union Power Station, located in the United States of America, plays a critical role in the regional energy generation landscape. Commissioned in 2003, this gas-fired power plant boasts an impressive capacity of 2428 MW, making it one of the significant contributors to the energy mix in Arkansas. Operated by Entergy Arkansas LLC, the facility utilises advanced gas turbine technology that enhances efficiency and reduces emissions compared to traditional coal power plants. The strategic location of the Union Power Station, with coordinates 33.2961 latitude and -92.5894 longitude, allows it to effectively supply power to the local grid and support the state's growing energy demands. As energy policies in the United States increasingly focus on reducing carbon footprints and promoting cleaner energy sources, gas-fired plants like Union Power Station are positioned as essential transitional technologies. They not only provide reliable baseload power but also support the integration of renewable energy sources by offering flexibility in energy output. The significance of this power generation facility extends beyond mere capacity; it is integral to maintaining grid stability and ensuring that Arkansas meets its energy needs. As the country navigates the path towards a more sustainable future, the Union Power Station exemplifies the role of natural gas in bridging the gap between conventional fossil fuels and renewable energy.
