Among various energy storage methods, pumped storage has multiple functions such as peak shaving and valley filling, frequency modulation, phase modulation, energy storage, emergency standby, and black start. It is currently the most mature energy storage technology with the lowest cost per kilowatt-hour. It also has characteristics such as a long service life, high conversion efficiency, large installed capacity, and long continuous discharge time. The energy conversion efficiency is about 75%. After the project is completed, the dam body of the power station can be used for about 100 years, and the service life of the motor equipment is about 50 years. In the past, the original pumped storage power stations were only occasionally called upon and did not necessarily participate in peak shaving and frequency modulation on a daily or weekly basis. Therefore, the calculated energy storage cost is relatively high. As the proportion of renewable energy in China's energy structure continues to increase, most pumped storage power stations will participate in intraday regulation in the future. Calculated based on one charge and discharge per day, the utilization hours of pumped storage power stations will be greatly increased, and the cost per kilowatt-hour of energy storage will be significantly reduced.

Looking ahead and aiming at the "dual carbon" goal, in terms of cost, photovoltaics has gained sufficient leading advantages among all renewable energy sources and will become the source of more than half to two-thirds of future primary energy and become a truly mainstream renewable energy. Investing in industries related to energy transformation such as photovoltaics and wind power, including supporting energy storage industries as well as electric vehicles, power batteries, energy storage batteries, etc. If the speed is well controlled, it is possible to form an industrial scale of 5 trillion yuan, 10 trillion yuan, 15 trillion yuan or even larger in recent years, becoming a driving force for economic development. At the same time, it makes all investments healthier, greener, more ecological, and more sustainable.

For the European Union, it is now facing the pressure of achieving energy transformation within twenty to thirty years. If it leaves or refuses to use components made in China, in fact, it may lead to a lose-lose situation. It is very difficult or impossible for Europe to complete energy transformation within twenty to thirty years. Therefore, in this sense, everyone should be realistic, be inclusive of each other, and jointly promote the energy transformation of mankind. This is the greatest realistic pressure and common need of all mankind.

The property of private enterprises and personal assets are protected by law and there are corresponding protection measures in the legal system. This is the greatest source of security and the greatest source of confidence in long-term stability for everyone. In this process, effectively protecting the rights and interests of enterprises and entrepreneurs through a society ruled by law so that everyone can continuously invest and expand reproduction without distraction and develop together at home and abroad is also a very important foundation. At the same time, if private enterprises and entrepreneurs can find a sense of honor and motivation to move forward from it, and the whole society jointly takes care of the creation and sharing of wealth, then everyone will have more stamina for efforts in development.

The rapid development of the photovoltaic industry makes us full of confidence in green development. From industrial silicon to polysilicon, and then to wafers, batteries, and modules, China's photovoltaic industry has completely realized a green manufacturing chain close to zero carbon and low carbon, which can effectively deal with the carbon tariffs and carbon barriers of the European Union and finally achieve global application. Regarding the instability of new energy power generation, pumped storage power stations have low energy storage costs and long service lives. With China's current manufacturing capabilities and industrial foundation, construction is not difficult. Power batteries and energy storage batteries are also developing very rapidly at present. The cost has dropped from several thousand yuan per kilowatt-hour to about 500-800 yuan per kilowatt-hour. The progress of technology, the increase in scale, and the drop in cost. The development speed in all aspects has impressed us.

In the future, the role played by energy storage must not be simply analogized with the present. Today's energy storage allocation is only occasionally invoked or even never invoked. In the future, energy storage should become an independent and important part of a smart grid and a new power system, maintaining the balance between the power generation side and the power consumption side and becoming an important industry under the market mechanism.

We often say that success is accidental, then failure is bound to happen sooner or later. When a pie falls from the sky and happens to land on your head, you think you can wait for pies every day without thinking about how the pies come. In this regard, we should think about how we can have pies every day and how we can truly and effectively control its inevitable arrival every day. In this process, the culture of internal and external benchmarking and internal and external sharing should penetrate into all aspects and become an endogenous driving force, so that every position is thinking about how to reduce costs, how to win gold medals and silver medals, and how much progress has been made today... Turn continuous improvement, continuous promotion, and continuous sharing into the spontaneous behavior of every employee and the driving force for continuous improvement. Only in this way can the company truly grow and develop steadily and continuously!

In the period of shortage economy, making do with whatever is available may be a way to survive. However, under the conditions of a mature market economy, every track and every field is subject to sufficient competition, full competition, or even excessive competition. If one engages in extensive land grabbing everywhere and is mediocre in everything without being specialized and refined, it is a lack of competitiveness for enterprises. Therefore, becoming specialized, refined, and strong in specialization, and then appropriately expanding in size is basically the logical premise that we believe can ensure lasting survival.

Gather momentum and focus, and strictly control boundaries. This is the summary of everyone's experience in the management practice process. Because it is single-minded, it is focused. There are some derivative products in the middle and later. Compared with other companies, we are single-minded and resolutely do not go to other branches. We concentrate funds, technology, research and development, and management resources, keep an eye on core technologies, and only make core products. Only through generations of focused progress can we achieve today's results.
