Economic Evaluation Of The Project In Power Plant With An Annual Output Of 1 Million Kilowatt Equipment

The economic evaluation theory of the project is by perfect competition mode in classical economics, it is its theoretical foundation that social utility theory, marginal analytical method, hard welfare that asks of handkerchief improve criterion, welfare economics, economics, development economics etc., absorb multi-disciplinary comprehensive cross discipline that the principle, principle and method in disciplines such as sociology, political science, mathematics, operations research,etc. develop at the same time, it is one of the important contents of technological economics in our country.Content, depth and emphasis point of economic evaluation, determined by the requirements of different stages of decision work of project. The economic evaluation at stage of project recommendation, the focal point is necessity and possibility of construction around approving and initiating a project, analyze that proves the economic condition of the project and economic situation, the content can be simplified appropriately, the depth is relatively simple; The economic evaluation at stage must be at the request of unified appraisal method and appraise the parameter that feasibility is reported, make overall, detailed, intact analysis and demonstration to necessity and feasibility of project construction. The economic evaluation of the investment project can be divided into two levels of financial appraisal and national economic evaluation mainly, including the financial affairs are analyzed, economic expense benefit analysis, the expense result is analyzed, uncertain factor analysis, risk analysis, regional economy and macroeconomy influence and analyze, its purpose is to recommend the optimum scheme to happen from a lot of schemes.With the development of global economy, the market of wind energy develops rapidly too. In recent years, world wind energy market has increased at the speed of 40% every year. It is estimated in the following 20- 25 years, world wind energy market will increase progressively by 25% every year. Now, the cost of electricity-generating of wind energy has already dropped to 1/5 of 1980. With the development of technological progress and environmental protection undertaking, wind energy can well compete with generating electricity with coal commercially while generating electricity. The wind-powered electricity trade of our country develops faster, but there is disparity greatly in the development level with the international wind-powered electricity trade, domestic wind-powered electricity start apparatus rely on import mainly, the foreign dependence is strong, though the wind-powered electricity cost has already dropped a lot, the advantage of comparing the cost of electricity generation by thermal power will not be obviously outstanding in a short time, there are a lot of hindrance factors in the development of the wind-powered electricity trade. It is exactly that what wind-powered electricity trade invested in is risky, must bring the high income for wind-powered electricity trade development, no matter wind-powered electricity economic benefits, benefit in society of industry, sustainable development that our country follow at present and save strategy, all these have offered very large development space for generating electricity in the trade.Wind-power electricity generation is another rising industry following industries such as IT,etc., develop and utilize renewable resources such as wind energy,etc. to become the main trend of international electric power development. It is reported, by 2020, wind-power electricity generation can offer 12% of an electric demand to world, can create 1,800,000 employment opportunities, can reduce more than 10 billion tons of discharge of waste gas such as the sulfur dioxide in the world.According to world wind energy committee (GWEC) Report,on the 2004 world wind energy increase industry 20%, wind-powered electricity of installations new ability is for 7,976,000 kilowatts, the total ability of wind-power electricity generation has already reached 47,407,000 kilowatts. In 2004, the generating capacity of wind-force of new installation of Europe accounted for 71.46% of the installed power-generating capacity of the global newly-increased wind-force. Secondly it is Asia, North America and Pacific Ocean area, is 15.9%, 6.4%, 4.1% respectively. Germany, Spain, U.S.A., Denmark and India are the largest country of generator installation ability of wind-force.Our country eastern wind electric field install first sets of Vestas55 kilowatts of wind scale generating set in Hainan 1985, through efforts of 20 the coming years, our country has obtained tremendous development in wind energy of development and utilization. Supported by country's projects such as national scientific and technological brainstorm project, 863 projects,etc., our country has already basically grasped the wind-force generating set and design and fabrication technology of the main part, have possessed 200, 250 kilowatts of, generating set batch production capacity of 600, 750 kilowatts of wind-force. During the 15, our country finish MW grades of wind-force reseach of generating set, establish the foundation that the wind-powered electricity industry participates in the market competition of regular energy, this ecological environment, adjustment of energy structure, realizing the sustainable development of national economy plays a positive role to our country. It is wind-force of 600 kilowatts generating set to install the most model in wind electric field of our country, with the constant improvement of the wind-powered electricity engineering level, the maximization of unit capacity becomes the trend of wind-power electricity generation. Installed 4 wind-force of 1300 kilowatts generating set in island wind electric field of celestial being of Yingkou of Liaoning in 2001, this is a unit of the unit with biggest capacity up until now of our country, developing 1500 kilowatts of wind-power electricity generation technology and equipment at home now.How appraise wind-power electricity generation economic benefits of investment project scientific, set up a whole set of system of index systems and effective appraisal method an important link that project appraise. Pass the appraisal analysis to the investment project of the trade here, can offer the reference suggestion of questions of the respects such as investment orientation, operation way, investment return, investment risk etc. to investors. Investment project market analysis, scheme that economic evaluation offer choose, financial affairs person who appraise data, can help to invest in a policymaker and draw correct conclusion opinion and project to choose to be proposed, offer the reliable basis for the fact that the policymaker confirms the topic. As systems such as the completion of the fund system of the investment project and project legal person's responsibility system,etc. are set up progressively completely, the fundamental change is taking place progressively in the investment environment of the project and financing environment. In this case, do a good job of economic evaluation of the project, can guarantee the project exchanges minimum investment for the best economic result, have very important function in project investment decision and operation construction of the project. This text, through obtaining a series of economic evaluation indexes on the foundation of analyzing the financial affairs to the project producing power plant of wind-force of a million kilowatts per year, every main economic evaluation index is: The returns on investment are 67%, the earning ratio within the financial affairs (after income tax)23% ,Financial the net present value (NPV) ' After the income tax) 731122 Wan Yuan, payback period of investment (after income tax)6.7 Annual, every financial evaluation index of this project is ideal, have good economic results. Being can see the profitability of the project by the balanced analysis of the profit and loss of the projected is high. Analyze to watch from the sensitiveness of the project, selling price, sales volume, cost, these three factors, have a little effect on project, it is obvious this project has no risk of obvious market. Analyze that can know through carrying on the different fields to the project producing power plant of wind-force of a million kilowatts per year, project economic benefits of Company and social benefit very kind build up, obviously, the project is feasible.
