Degray Hydroelectric Power Plant | Arkansas, United States

Degray is a hydroelectric power plant located in Arkansas, United States, with a generating capacity of 68 megawatts (MW). The facility is owned and operated by the US Army Corps of Engineers Vicksburg District and is currently operational. As a hydroelectric plant, it harnesses the energy of flowing water to produce electricity, contributing to the region's renewable energy portfolio. The plant operates under the regulatory framework of the United States, including the Clean Air Act and state-level environmental regulations. Hydroelectric power is a low-emission energy source, and Degray's capacity places it in the small-to-medium scale range for hydropower. The facility utilizes conventional dam-based technology typical of run-of-river or reservoir hydro projects. Degray plays a role in supporting grid stability and providing clean energy to the surrounding area. Its operation aligns with national goals for renewable energy generation and carbon emission reduction. The plant's location in Arkansas benefits from the region's water resources and contributes to local energy independence.

As a hydroelectric facility, Degray produces electricity with minimal direct air emissions, avoiding the CO2, SOx, and NOx associated with fossil fuel plants. However, the dam and reservoir can affect local aquatic ecosystems and water flow regimes. The plant's capacity of 68 MW is moderate, and its operation is subject to environmental regulations including the Clean Water Act and state water quality standards.
