Electrical equipment: natural gas power generation will usher in the golden age
Natural gas is the best alternative energy source for coal. As early as during the two sessions of the two sessions in 2014, Premier Li Keqiang’s participation in the discussion and deliberation of the Shanxi delegation has already proposed that the management of smog should change China’s current coal-based energy structure. Compared with coal and oil, there are very few substances in the combustion process that can affect the health of human respiratory system. The carbon dioxide produced is only about 40% of coal, and the reduction of sulfur dioxide and dust emissions is nearly 100%, reducing nitrogen. Oxygen emissions of 50% are the best alternative energy source for coal.
Two adjustments to natural gas during the year reduced costs. After the natural gas has been price-adjusted twice, the price is rapidly transmitted downwards and transmitted to the natural gas terminal application provider to reduce the gas cost of the natural gas power generation enterprise including the distributed power producer. At the same time, due to the price linkage between the electricity price and the gas price, The price of natural gas on-grid in various provinces and cities has been adjusted accordingly. For example, the capacity of the natural gas peak-shaving generator set and the natural gas cogeneration unit of the Shanghai Municipality has remained unchanged. The electricity price has been adjusted from 0.5696 yuan per kWh to 0.4856 yuan per kWh. The electricity price of some natural gas power plants in Zhejiang Province was adjusted from 0.73 yuan per kWh to 0.60 yuan. At present, natural gas distributed power generation is still unable to access the Internet, and direct grid-connected sales to users, but the price of electricity sold will also benefit from the reform of natural gas prices.
Natural gas power generation has three major advantages. 1. Environmental benefits, energy saving and emission reduction are significant: CO2 emissions are only 42% of coal-fired power plants; NOX emissions are less than 20% of coal-fired power plants; 2. Distributed natural gas power generation can improve the safety and reliability of users' energy use. Sex: There are multiple systems for cooling, heat and electricity output as redundancy. The municipal power grid is used as a backup. In the case of grid power loss, it can still maintain uninterrupted power supply. 3. Efficient use of energy: distributed natural gas power generation Energy efficiency can be increased from 40% to 70%-90%.
The three major problems that hinder natural gas power generation have been resolved to varying degrees. Previously, there were three major problems that hindered the development of natural gas distributed power generation: first, the gas price was too high and the gas source was short; second, it could not be connected to the grid; third, the gas turbine independent technology still belongs to overseas companies, resulting in the absence of core technology. It is also necessary to pay the maintenance cost equivalent to the gas turbine price. Now, the three major problems have been solved to varying degrees, and the natural gas distributed generation will usher in the golden period of development.
Investment advice and industry rating. We believe that the situation of oversupply of natural gas still exists, and there is still room for downward adjustment of prices. As an alternative energy source for coal and oil, natural gas is expected to continue to be prominent, and downstream demand will be stimulated. At the same time, the advantages of natural gas power generation, especially distributed generation, will continue to be recognized by the market, and natural gas power generation will usher in a golden age.
