Gases de Occidente is a natural gas distribution and commercialization company serving 27 towns in the area of Valle del Cauca, located on Colombia's west coast.
Gases de Occidente operates under a concession agreement with the Colombian MME for exclusive service areas which expires in 2014 (when the term ends this area will change to being regulated by CREG) and for nonexclusive service areas in 2047. Since 1994, a concession has no longer been required to provide gas distribution as a public service in Colombia.
