Overview
Calama 2 is a 9 MW solar PV facility located near Calama, Chile. The plant is operational and contributes to Chile's growing renewable energy capacity.
Calama 2 is a solar photovoltaic (PV) power plant located near Calama in the Antofagasta Region of Chile. With a capacity of 9 megawatts (MW), it is a small- to medium-scale solar installation that supports the country's renewable energy expansion. The facility is operational and benefits from the high solar irradiance characteristic of the Atacama Desert, one of the best solar resources globally. The plant operates under Chile's renewable energy regulatory framework, which includes a target of 70% renewable electricity by 2030 and carbon neutrality by 2050. Solar PV is a key technology in Chile's energy mix, with large-scale projects concentrated in the northern regions. Calama 2, while modest in size, contributes to grid stability and local energy supply. Environmentally, the facility occupies desert terrain with minimal land-use conflict. Solar PV in arid regions like this has low water consumption and no direct emissions, aligning with Chile's climate goals. The plant's output helps reduce reliance on fossil fuels and supports the local mining industry's demand for clean energy.
Environmental context
The Calama 2 solar PV plant is located in the Atacama Desert, one of the driest regions on Earth. This environment offers exceptional solar radiation levels, maximizing energy generation efficiency. The desert ecosystem is sensitive to land disturbance, but solar installations can be designed to minimize impact. The plant's operation avoids water use typical of thermal power plants, preserving scarce local water resources. Its clean electricity displaces fossil fuel generation, reducing air pollution and greenhouse gas emissions in a region with significant mining activity.
