Special research: new energy storage development scheme to ensure the smooth transformation of new energy power system
The implementation plan for the development of new energy storage in the 14th five year plan points out that "clarify the independent market position of new energy storage, energy storage will enter large-scale development in 2025, realize the full marketization of new energy storage in 2030, and basically meet the needs of building a new power system". At present, the pace of electrochemical energy storage research and development is further accelerated, various technologies and industrial pilot projects are steadily promoted, and the cost of electrochemical energy storage will be reduced by 30% in the future. The construction cost of pumped storage power station is about 6 yuan / watt, and the kilowatt hour cost is only 0.21-0.29 yuan / kWh. At present, it has a certain cost advantage.
Investment strategy: Public Utilities: 1. The reform of electricity marketization is promoted, and the electricity price can better reflect the value of supply and demand, cost and environment. The construction cost of new energy continues to decline. New energy operators have "triple" certainty, and the growth rate of "quantity" - scenery installation has high certainty; "Price" - the price of thermal power rises, the green premium is superimposed, and the profit space of green power is opened; "Performance" - this year's low-cost fans and rush to install sea breeze ensure the performance of next year. 2. The policy promotes the optimal combination of coal and new energy. The policy of Changxie coal price + Changxie electricity price is expected to be implemented, the linkage mechanism is formed, the market-oriented trading of coal and electricity is expanded, and the turning point of thermal power profit appears. 3. The construction of new power system with new energy as the main source will deeply benefit new energy power producers and comprehensive electric energy services. Recommend good cash flow, "nuclear power and new energy" two wheel drive China National Nuclear Power Co.Ltd(601985) ; It is recommended to actively transform new energy sources with abundant cash flow, leading thermal power Huaneng Power International Inc(600011) etc; New energy operation leader with capital cost and resource advantages China Three Gorges Renewables (Group) Co.Ltd(600905) ; Comprehensive electric energy service Suwen Electric Energy Technology Co.Ltd(300982) . Environmental protection industry: 1. High performance and low valuation; 2. 3. Continuous improvement of cash flow and business indicators: continuous improvement of business income. Recommend recycled paper as the leading Zhejiang Rongsheng Environmental Protection Paper Joint Stock Co.Ltd(603165) .
Risk warning: the environmental protection policy is not as expected; The growth rate of power consumption decreased; Electricity price reduction; The terminal price of natural gas has been reduced.
