 An interesting characteristic of the Colombian electricity sector (as well as of its water sector) is a system of cross-subsidies from users living in areas considered as being relatively affluent, and from users consuming higher amounts of electricity, to those living in areas considered as being poor and to those who use less electricity.The electricity sector has been unbundled into generation, transmission, distribution and commercialization since sector reforms carried out in 1994.About half the generation capacity is privately owned.
