As of early 2012, the construction cost of a $10 million ground-mounted power plant was only a little more than 100 million yuan, but the profit recovery depends on local resource conditions light, production capacity. of such a power plant can reach 1,700 million kWh of electricity, but these areas are usually in deserts. According to the current national policy, the price of electricity on the grid is 1 yuan/kWh, which is less than 20 million, so it is necessary. almost six years to repay the cost, and the lifespan of the power plant is about 25 years, so the income is still not bad. If the resource requirements are limited and the local government provides subsidies, the electricity price on the grid may increase by 30-50%, so you need to understand it in detail Haha, I don't know if it is your answer. need.
Northwest China, the total investment to build a 10 megawatt power plant is expected to be around 80 million Haha, the cost of electricity has been significantly reduced, but investment institutions have become more expensive due to various factors. reasons. Be careful, transmission resources and the impact on the power grid will be considered more, so everyone is actually more concerned about distributed projects connected to the grid, and most of these projects are not located at l west, although electricity production is not as significant. good as in the west, the areas where these projects are located are relatively developed, have a high local consumption capacity and have less impact on the electricity network. Additionally, they have a large proportion of rooftop projects and more national and local political subsidies. , so it received more attention from investors.
By mid-2013, prices should have dropped a lot, haha
Building aMWsolar power plant It probably costs around 10 yuan. How many kilowatt hours of electricity can be produced each year? 120 kilowatt hours of electricity.
If the efficiency of the photovoltaic power plant system is within a reasonable range, taking the Beijing area as an example: the annual use of each kilowatt is about 1,200 hours , then the actual annual electricity production of 1 MW is approximately 1200 H*1000 KW = 1.2 million expenses.
Example
Shanghai Shenergy Company invested 65 million yuan to build a 1 MW solar power plant. The theoretical electricity production value of a 1 MW power plant is 1,000 kilowatt hours per hour.
It produces electricity 6 hours per day. 6000X365=2190000 kWh.
