Foreword he E7 was born in April 1992 when the chairpersons and chief executive Tofficers of some of the largest electric utilities in the Group of Seven (G7) industrialized nations agreed to meet once a year at an E7 Annual Summit to discuss major global issues related to the electric utility industry.Their common goal: “to play an active role in protecting the global environment and in pro- moting efficient generation and use of electricity.” To that end, they created the E7 Network of Expertise for the Global Environment to act as a pro bono environmental, technical and industrial advisory group for electric utilities and governments in developing and Eastern European countries. The E7 Network has already provided in-kind services in more than thirty projects in Asia, Latin America, Africa, and Eastern Europe. Furthermore, E7 Working Groups are mandated on an ad hoc basis to examine specific policy issues relevant for the global electricity industry and develop E7 proposals, position papers and policy statements to bring the E7’s voice to the international community and facilitate exchanges with international organizations and electric utilities in developing countries. One of the E7’s active Working Groups took an in-depth look at the issue of regional electricity cooperation and integration (RECI), both as a specific tool for the development of the electricity supply industry in developing countries, and as an effective means of enhancing the industry’s contribution to the sus- tainable development of those countries. Developing countries are specifically targeted here, considering the relatively low level of power system integration between those countries and the large potential offered by RECI to optimize their development in a more profitable manner. This document and its accompanying CD-ROM provide a comprehensive examination of the conditions necessary to the successful implementation of regional electricity cooperation and integration, through the pooling of resources and the interconnection of electric power systems. It draws largely on the expertise and experience of E7 members, and on practical examples from both developed and developing nations. The E7 and the E7 Network of Expertise for the Global Environment are confident that the information, ideas and guidelines put together by the RECI Working Group will contribute in a timely and practical manner to the full realization of the benefits – political, social, economic and environmental – which can accrue from sharing electric power resources.
