Despite these obstacles, no company decided to withdraw from the region, with the partial exception of EDF (which maintained just a single generating plant in Brazil). This situation has now changed, however, and in recent years these companies have announced ambitious investment projects in the region, generally targeting the organic growth of the markets in which they were already present — except for Argentina, where transnationals operating in the country (Enel, Duke Energy and AES) have not announced any expansion plans. The projects in question cover transmission, distribution, and generating businesses alike, and include a substantial increase in renewable energy projects (apart from hydroelectric power plants). This means that Latin American assets are now extremely important for the firms in question, since they are in markets with growth prospects offering generally high returns.
