Harquahala Generating Project - 1,325 MW Gas Power Plant in Arizona, USA

Harquahala Generating Project is a gas-fired power plant located in Arizona, United States, with a capacity of 1,325 MW. This large-scale facility is owned by New Harquahala Generating Co LLC and plays a significant role in the regional power grid. The plant operates under the regulatory framework of the US Environmental Protection Agency, including the Clean Air Act and associated programs such as the Acid Rain Program and CSAPR. As a gas-fired plant, it utilizes combined cycle or simple cycle technology typical of modern gas power generation, offering lower emissions compared to coal-fired plants. Harquahala Generating Project contributes to the electricity supply for Arizona and surrounding areas. Its substantial capacity positions it as a major asset in the state's energy mix, supporting grid reliability and meeting demand from residential, commercial, and industrial consumers.

The Harquahala Generating Project, as a gas-fired power plant, has a lower carbon footprint compared to coal plants but still emits CO2, NOx, and SOx. Its location in a relatively arid region of Arizona may influence water usage for cooling. Proximity to populated areas and the plant's age and technology (likely combined cycle) are factors in its environmental impact. The facility must comply with US EPA emissions standards under the Clean Air Act.
