60% of its power will be coming from renewable energy sources.
Chilean president Michelle Bachelet announced this week Metro de Santiago will be powered up to 60% by solar and wind energy. This will also power lighting inside stations and the system's offices.
This will be possible due to two agreements with the solar plant El Pelicano and the San Juan's Eolic Park. Both plants are under construction and will be finished by 2018.
The solar plant will be developed by SunPower, whose majority owner is French oil company Total. San Juan wind project is under Spain-Based Elecnor who's owned by Brazilian renewable energy firm Latin American Power.
The subway will be receiving its energy from these two for the next fifteen years through the Interconnected Central System (SIC). An state investment of more than 500 million dollars is required for the project.
When operational 40% of the energy supply will come form Chilectra (Private Chilean electric energy supplier), 42% from El Pelicano and 18% from San Juan.
President Bachelet said the project is part of Chilean efforts to guard the environment and achieve the Paris agreements and it will be crucial for showing competiveness and development in the renewable energy sector.
The use of renewable energies for the project will be equivalent to 104,000 homes and it will help to reduce up to 130,000 tons of CO2 annual emissions.
Metro the Santiago is the second largest in Latin America behind Mexico City's. It has over 100 stations and five lines and a sixth under construction. Over 2 million people use the system daily and when Estadio Nacional station is functional over 3,7 million people are expected to use it over the year.
