The proper allocation of the limited R&D resources under the restructuring of the electric industry is a primary motivator for this electricity technology roadmap (eTRM) initiative. Because the major interests of CEOs could be the short term profit of their company under the competitive electric industry, it would wrong of them to cut back on the long term R&D budgets which make it impossible to develop all the technologies. Therefore, we should select and support only the favorable and competitive technologies to meet the future market needs using the TRM approach with the concept of "Selection and Concentration." This study aims at defining the key technologies basis from the forecasts of what is possible or likely to happen in the future and planning the course of action for the technology development in the electricity field in Korea. The selected technologies could be the candidates for the mid and long term R&D program supported concentrically by the Electricity Industry Infrastructure Fund.
