DIESEL ENAEX (CUMMINS-DEUTZ) - 2.7 MW Diesel Power Plant near Antofagasta, Chile

DIESEL ENAEX (CUMMINS-DEUTZ) is a small-scale diesel power plant located near Antofagasta, Chile, in the Antofagasta Region. With a capacity of 2.7 MW, it falls into the small-scale category for power generation, typical for industrial backup or remote power applications. The plant is owned and operated by ENAEX, a major Chilean explosives and industrial services company. As a diesel-fired facility, it operates using internal combustion engines, likely based on Cummins or Deutz technology. Diesel plants are known for their quick start-up and flexibility, making them suitable for peak shaving or emergency power. In Chile, such plants often support mining operations or isolated grids, though this facility's specific role is not detailed. The plant is operational and contributes to local energy security. Environmentally, diesel power generation produces higher CO2 emissions per MWh compared to natural gas or renewables, along with SOx and NOx. The plant's small capacity limits its overall impact, but its proximity to populated areas near Antofagasta may require compliance with Chilean emission standards. Modern engines typically incorporate emission controls.

The plant uses oil (diesel) as fuel, which results in higher CO2, SOx, and NOx emissions per unit of electricity compared to natural gas or renewable sources. Its small capacity (2.7 MW) limits total emissions, but the facility's location near Antofagasta, a coastal city with a population over 300,000, means local air quality considerations apply. Chilean regulations, such as the Emissions Standard for Thermal Power Plants (DS 13/2011), set limits for SO2, NOx, and particulate matter. The plant's age and specific emission controls are not known, but modern diesel engines often include after-treatment systems.
