4 Letter from the Chairman On behalf of the CDEC-SIC Board of Directors, I am pleased to present you with the 2012 version of the Central Interconnected System (SIC) Operation Statistics, published annually by the Center for Economic Load Dispatch (CDEC-SIC), and made available to all stakeholders and investors interested in the Central Interconnected System management. The information contained in these Operating Statistics covers the term from 2002 through 2011, both included. This publication delivers the most significant operation data of the SIC, the main national electricity system which serves nearly 92% of the country s population located in the geographic area between Rada de Paposo to the North and Isla Grande de Chiloe in the south was characterized by a poor rainfall, reaching a surplus probability of 84%, making it one of the statistically driest years ever. This drought was the continuation of an also dry 2010, which caused the authority to enact Decree No. 26 on February 2011, establishing preventive measures aimed to avoid future supply deficit and to ensure electricity supply at the SIC. Regarding relevant data on energy, power and capacity, it should be noted that the gross energy generation in 2011 increased by 6.7% as compared to 2010, totaling 46,142 GWh. On the other hand, energy sales totaled 43,804 GWh, 6.7% increase as compared to sales in Regarding power demand in 2011, the annual maximum value reached 6,881.4 MW, 6.2% increase over the demand recorded in 2010, while the maximum peak period demand reached 6,016.3 MW, representing a 4.1% growth for the same variable as measured in As of December 31, 2011 the installed capacity in the SIC system reached 12,715 MW, 4.7% higher than the one available at the end of This increase is largely explained by the hydro projects operation start-up, which totaled an amount close to MW. At the regulatory level, and pursuant to Supreme Decree No. 291/2007, in 2011 a new election process was established for the renewal of the CDEC-SIC Board. A meeting of the member companies was held in October, where representative directors were elected from each of the segments that are a part of the CDEC-SIC. This new Board took office in November last year. 2

5 Also in 2011, by decision of the Board, a professional lawyer joined the Secretariat of the CDEC-SIC as Secretary to the Board. On the other hand, the Board tasks in 2011 included the following activities: - Development of a Diagnosis and Improvement Study on the CDEC-SIC Operation Management, aimed to identify opportunities for improvements in the operational management of the CDEC-SIC, to ensure high performance standards in line with best international practices. This study, designed as an independent diagnosis about processes, structure and other key aspects for the good compliance with the obligations as established by the current legislation and, in particular, with regard to the safe and economical operation of the Central Interconnected System, was entrusted to a prestigious international consultant and was developed by the Operations Director, according to the criteria defined by the Board. The recommendations to be derived from this study should provide the basis for processes and infrastructure improvements that may be a part of this CDEC s future tasks. - Development of a CDEC-SIC organization study, designed by stages and oriented to define and establish the feasibility of this CDEC within the institutional framework of the current legislation, to act in the legal life and perform their functions as defined in Decree 291/2007, under a different type of organization to the one that at present provides administrative support. Such study is in progress and it has required various specialized consulting services, for which the Board approved a supplementary budget. - Proposal for amendments to the Internal Regulations of the CDEC-SIC in several areas, to adapt to the new needs of the system s internal organization and operation. - Agreements and definitions regarding the treatment adopted to address the impact on the system caused by the situation of unpaid bills related to the transfer of energy and power balance, by the companies Campanario Generación S.A. and Central Tierra Amarilla S.A. - Adoption of general criteria to implement a new organizational structure, to review the location of the CDC, and to implement a communications consultancy. In 2011, the interest of member companies to seek consensual solutions to the discrepancies that arise in the operation of the SIC was also raised, since only two differences were presented for consideration to the Panel of Experts: Decision Nº 12, November 2011, which solved the Discrepancy of Empresa Electrica Guacolda S.A. for the inclusion by Tolls Direction of CDEC-SIC of the company Campanario Generation S.A. in the August 2011 Transfer of power and energy Balance, filed in September, while Decision Nº 24, January, 2012, solved the Discrepancies with the DP Procedure: Calculation and Determination of Economic Transfers of Energy, filed in November. Regarding budget, it is worth highlighting the Board s approval of a 2012 budget with an increase of around 50% as compared to the previous year, in order to carry out the required innovations to the functional structure of the CDEC-SIC, as well as in the development and acquisition of technological tools in order to provide the entity with the flexibility allowing to continue successfully facing the duties and challenges of an industry in continued growth, particularly those related to preserve safety in the electrical system. I conclude by expressing my sincere thanks to all the people who work professionally at the CDEC - SIC, and to all those who have supported this organization s Board management, which I am honored to chair. I would also wish to acknowledge the task of the Operation and Tolls Director, and the Administration and Budget Director for their efforts towards an electricity service with the standards of quality and safety that the country demands. Rodrigo López Vergara CDEC-SIC Chairman of the Board 3

6 Letter from the Director of Operations and Tolls I am pleased to present the industry and the general public with the Operations Statistics prepared annually by the Center for Economic Load Dispatch - Central Interconnected System - (CDEC - SIC). This document shows the most significant indicators and elements of SIC s operation, which on this occasion refer to the term When analyzing demand supply during 2011, a significant thermal component (54.7%) may be noted, as a consequence of poor hydrology at the main dams of the system after an equally dry year Under such a condition, in order to prevent supply deficit situations, in February 2011 the Ministry of Energy enacted Decree Nº26 which incorporated, among other, measures such as voltage reduction, formation and maintenance of a hydric reserve, promotion of consumption decrease and powers to the Operations Director to operate transmission facilities under special conditions, allowing to successfully overcome the tight supply situation of year Regarding new infrastructure, during 2011 production capacity of the hydraulic generating facilities increased by MW, while the thermal ones increased by 53.9 MW, discounting Central Ancud disconnection.
