Regulation of Transmission Expansion in Argentina: Part II – Developments Since the Fourth Line

Argentina’s 1992 transmission expansion policy was subsequently modified by, for example, including provision for transmission companies and proposing quality and substation expansions. There have been several such expansions, and no lack of investment in quality and reliability of supply. In 1999, reflecting a decision to give greater weight to political considerations, a Federal Transmission Plan was introduced to build lines designated by the federal and provincial governments. The original reform led to less investment in major transmission lines but more intensive use of existing lines. Competition to construct expansions developed, leading to lower construction costs. Thus the Argentine transmission expansion mechanism was a considerable success in terms of meeting the requirements of users efficiently. This experience suggests that involving users in the regulation of monopoly networks is feasible, and the scope for it may be greater than generally appreciated. However, the reconciliation of economic and political considerations needs further consideration.(This abstract was borrowed from another version of this item.)
