Energy Efficiency

PARTICIPATION IN CLG CHILE

In 2010, Enaex joined CLG, the Corporate Leaders Group for Climate Change founded in the United Kingdom in 2005. The group has been one of the most consistent voices to openly support development of global-level public policy that combats the effects of climate change while maintaining a favorable business environment.

With more than 10 years experience on greenhouse gas emissions reduction projects and, internationally, on emissions trading systems, each year Enaex makes financial contributions to and participates in the technical committee that supports government entities in establishing policies and instruments that facilitate the transition to a low-carbon economy. These policies and instruments also translated into sustainable development opportunities for Chile, through a high-level gathering on leadership and business innovation.

In 2018, subsidiary Enaex Colombia joined the CLG group in Colombia, confirming the Company’s commitment to reducing global warming.

ENERGY EFFICIENCY

Since 2010, the Company has developed energy efficiency projects that have significantly reduced operating costs and indirectly reduced CO2 equivalent emissions.

IN 2018, SELF-GENERATION USING THE STEAM GENERATED BY THE PRILLEX AMERICA PLANT, WHICH WAS RESPONSIBLE FOR 95% OF THE COMPANY’S ENERGY CONSUMPTION IN CHILE, REPRESENTED NEARLY 60% OF POTENTIAL CONSUMPTION.

In self-generation, 2.5 MWh were attributable to the Panna 4 turbo compressor, 1.0 MWh to installation of frequency variators at Panna 3 and 1.4 MWh to the back-pressure turbine installed in 2016.

THESE MEASURES HAVE SUPPORTED AN 18% DECREASE IN INDIRECT EMISSIONS FROM ENERGY CONSUMPTION IN THE CORPORATE CARBON FOOTPRINT SINCE 2014.

On the other hand, 100% of the corporate buildings are equipped with LED lighting.

ENERGY CONSUMPTION

In 2018, Enaex’s consolidated energy consumption was 171,841 MWh.
