| With China's rapid economic development, Electricity demand growth rate of the user side has remained at a high level. And our long-term re-generation, light power-oriented, leading to weak supply network frame structure, power transmission equipment, poor performance status, power supply.For weak grid infrastructure, China's power grid companies have increased investment in fixed assets on the grid. Research and study in the power grid under the new situation of fixed assets investment benefit evaluation approaches, methods and systems building, has become a top priorityThis evaluation of the effectiveness of the use of modern investment theory and methods, business investment in fixed assets for power efficiency evaluation are described, introduced the evaluation of the contents of the grid investment returns and characteristics of investment appraisal of the theory, network formation and fixed assets management, the main benefit evaluation methods and content, evaluation of investment returns of assets around the grid analysis, power grid enterprises to build for the benefit of investment in fixed assets evaluation system for power grid companies have to play a regulatory evaluation of the investment and facilitating role.Power companies benefit evaluation of investment in fixed assets investment projects already completed or planned project decision-making, the goal of building, design, construction, completion and acceptance of, the whole process of production and operation of a comprehensive analysis of the system, through the process evaluation, economic evaluation, impact assessment, continuous evaluation of their produce in four areas of financial and economic, social and environmental impact and sustainability with the objective of the comprehensive summary of a comprehensive analysis of investment projects achieved the expected goals, summed up its lessons for future similar project reference.This paper summarizes the relevant fixed asset investment benefit evaluation based on the theory and methods to transform M City ABC Electric Power Grid, for example, to analyze the investment benefit evaluation of the status quo and existing problems, and to give enhanced benefit evaluation of their investment strategies, in order to better grasp the direction of business investment in the future. |
