This version of the plan starts with a brief description of the country’s main macroeconomic aggregates recent evolution. Chapter 1, Economic Situation, with the purpose to present the analysis and results. Chapter 2, Electricity Market Situation, presents data, indicators and relevant events in the different segments of electricity chain, from the electric power demand to the supply, starting with international interconnections, and finishing with a review of the regulatory scheme modifications since 2005, used to define the methodology and scope of the Plan. The energy demand and electric power projections, used in the analysis performed, as well as their methodological aspects, are the purpose in chapter 3. In Chapter 4, Resources Availability, Natural Gas and Coal Prices Projection, are inputs for further chapters. The Expansion and Generation studies, described in Chapter 5, are based on expansion projects foreseen for Colombia, as well as for neighboring countries such as Ecuador, Peru, Panama, and other countries which are part of SIEPAC (Electric Interconnection System for Central American countries), considering the possible states that arise from simultaneousness between the four critical variables which determine the various scenarios of generation expansion requirements in the country: gas price and availability, increase on energy demand and the carry out of international interconnections. In this plan, the need to incorporate at least 150 MW by 2009 and 700 MW for the period between 2011 and 2015, or 1000 MW, for same period, if the interconnection with Central America is carried out, and if there is a high increase on demand and as well as a need for new generation capacities based on mineral coal are identified. The analysis of the Transmission Expansion on Chapter 6, considers the Bogotá
