The purpose of this study is to investigate methods for reinforcing the Eastern area power system by overcoming the present and future problematic conditions. In preparation of this paper, every possible effort is given to concise the contents without loosing the key topics. The study comprises three consecutive phases. The first phase consists of a comprehensive study of the Eastern area power system, finding out key problematic conditions, studying the potential solutions obtainable from within the same area under four different system operation scenarios. The second phase consists of two analytical stages. In the first stage, more concern is devoted to different types of solutions to overcome the present day problems such as the voltage droop, line overloading problems etc. Ten different types of proposals based on dependable view points, thoroughly revised with the help of power flow studies are also given in this section. The second stage search out possible solutions not only for the present but also for ten years ahead from year 2005. For the selected study period of 2005- 2014, a series of detailed analysis have been carried out in yearly basis with remedial actions wherever seemed necessary. The final study consists of six different types of alternative solutions capable of withstanding five types of criteria under system normal condition as well as under single contingency condition. Final phase is a technoneconomic analysis of each of the six solutions selected, for optimisation. Although not included, a series of studies on fuel transportation and an account on social & environmental impact assessment also have been carried out which are inherently essential parts of a similar project.
