DEGAN Diesel Power Plant, Los Lagos Region, Chile

DEGAN is a diesel power plant located in the Los Lagos Region of Chile, near the coastal town of Ancud on Chiloé Island. With a capacity of 36 MW, it is a medium-scale facility within Chile's power generation sector, which relies on a mix of hydroelectric, natural gas, and diesel sources. The plant is owned and operated by GENERACION DE ENERGIA NUEVA DEGAN S.A. and is currently operational. The plant uses oil as its primary fuel, typical for diesel power plants that serve as peaking or backup capacity in regions with limited grid connectivity. Chile's energy regulatory framework, overseen by the Comisión Nacional de Energía (CNE), sets emission standards for such facilities, including limits on SOx, NOx, and particulate matter. The plant's technology likely involves internal combustion engines, which are common for diesel plants of this size. Located in a region known for its temperate rainforests and coastal ecosystems, the plant's operations are subject to environmental oversight to minimize impacts on local air and water quality. As a diesel facility, it contributes to grid stability in an area where renewable energy sources like wind and solar are growing. The plant's role is significant for local energy security, particularly during periods of low hydroelectric output.

The plant operates in the Los Lagos Region, an area with high precipitation and sensitive aquatic ecosystems. Diesel combustion emits CO2, SOx, NOx, and particulate matter, which can affect local air quality and contribute to acid deposition. Proximity to the coast and populated areas necessitates adherence to Chile's emission standards, which align with international best practices. Older diesel plants may have higher emissions per MWh compared to modern combined-cycle units.
