Research On Investment Cost Control Of Daliping Solar Photovoltaic Power Station

The modernization of the world economy benefits from the wide application of fossil fuels(such as oil,gas,coal and nuclear fission energy).Taking electricity as an example,for the reason of energy crisis and the impact of the traditional energy on the environment,the ratio of electricity generation that only rely on coal and petroleum will be gradually reduced,and new energy mainly including wind and solar energy will have greatdevelopment in the future.With the increasing maturity of electrooptical technology,photovoltaic generation has become one of the most promising renewable energy sources now.At present,the state formulates Yun Nan province benchmark price of grid-connected photovoltaic power station project is 0.95 yuan / kW · h(tax included).Compared with hydropower,thermal power,wind power generation,the price is higher than twice or several times.As more and more PV power station put into operation,the government is likely to gradually cut subsidies,tariff couldn't have been maintained at a high level.In the case that feed-in tariff are expected to be lowered down,how to carry out cost control will be crucial for the enterprises investing the constructions of photovoltaic power stations.In addition,multiple types of power stations have been newly built in recent years,the discarded electric quantity has been rising year by year,it's difficult to guarantee the stable annual generation amount.Especially,during the wet season,most of the hydropower station cannot be fully loaded with power generation.This year,new energy power plant approval has become more and more strict,many projects were halted.On the one hand,the approach of government is intended to avoid the risk of decline in quality because of these projects being built in a confused manner;on the other hand,considering the interests of investment enterprises,the decline of the government subsidies is a trend now.Da Liping solar photovoltaic power station still in the feasibility study stage has not been implemented yet.The site is located in Huangping town,Heqing county,Dali prefecture.From the geographical point of view,the high annual radiation is very suitable for the development of photovoltaic projects.According to prediction,the power load of Dali prefecture have room to grow in the next period of time.In present period,general photovoltaic power plant investment cost-recovery time is about 10 years.But this data may be extended for several years,there are certain risks in it because the power gap reduce gradually also the government is likely to reduce subsidies.In this thesis,the investment cost of Da Liping photovoltaic power plant will be analyzed item by item.According to the projected scheme to produce financial statements,through earnings to measure the project investment,and finally puts forward some key points to control the cost of investment.
