Chairman's speech

Light is energy, water is energy ,wind is energy, earth is energy, information is also energy, but Albert Einstein said: "It wasn't until the end that I realized that the source of all energy in the universe is 'love'!"

In 1999, at the turn of the century, with the connotation that "love" is the source of all energy in the universe, Zhiguang established "helping customers to use energy safely, economically and comfortably" as the company's business philosophy, and started the road of unremitting search for technological innovation, product innovation, service innovation, and mode innovation in the field of digital power systems.

Entrepreneurship and innovation is a heavy corporate and social responsibility. Over the past twenty years, Zhiguang has overcome one technological innovation issue after another, and has continuously promoted the progress of energy technology in the fields of industrial energy saving, energy storage and integrated energy services, and has become the industry advocate and leader of many new technologies! At present, Zhiguang's products and services have been widely used in more than 40 countries and regions around the world, more than 4,000 customers, in the power grid, power plants, new energy, iron and steel metallurgy, cement and building materials, ports and other important industrial scenarios for many times to participate in the construction of national key projects; the company's first research and development of cascaded high voltage energy storage system is the world's electrochemical field of charging and discharging the cycle efficiency of more than 90% of the only technology route, the stand-alone power up to 25MW, can reduce the construction cost of large-scale energy storage power station by 13%, but also for the world's large-scale shared energy storage power station provides a more excellent solution!

At present, the products and services provided by Zhiguang can save the country 36.4 billion kWh of electricity, reduce carbon emissions by 34.5 billion kilograms, and save 14.56 million tons of standard coal every year. Zhiguang is committed to achieving China's dual-carbon goals tirelessly and tirelessly...

Nowadays,  during  the  development  opportunity  of national  energy  change, Zhiguang keeps its original intention and mission, and makes every effort to help the green and low-carbon transformation and upgrading of energy. Zhiguang will continue to  focus  on  integrated  energy  technology,  power  electronics  technology,  digital technology and application, focusing on the large-scale development of energy storage, and continue to enhance the key business of new power system; through technological innovation, service innovation, business model innovation, and capital operation, it will build a multilevel operation structure and an open operation platform , and create a leading digital energy technology and integrated energy service enterprise group in the new development concept of dual-carbon.

The ultimate  goal  of innovation  is to  create  a better  life  for human beings! Zhiguang will uphold the spirit of       "innovation, responsibility, unity, perseverance", work with more like-minded people, through practical industrial practice, and jointly look forward to the energy Internet linking all the energy of   "love", so that people can bathe in the warm world of energy, feel the truth of   "love" and realize the true nature of life.
