On June 8, 2022, our company once again signed a procurement contract with a Chinese tower customer for the "2022 China Tower Wind and Solar Complementary Maintenance and Renovation Project". Our company has maintained continuous cooperation with customers of Iron Tower Company for many years, and the company has been highly recognized by Iron Tower customers in terms of project delivery of complementary communication base stations for wind and solar power off the grid. The wind solar complementary system is mainly applied to users who are far away from the large power grid, in a state of no electricity, sparsely populated, with low electricity load and inconvenient transportation. It is an economic and practical power station constructed by utilizing the abundant wind and solar energy in the local area. Over the years, our company has built over 100 wind solar complementary power supply systems for tower communication base stations, border checkpoints, forest fire prevention, and other facilities across the country. Compared to power network management renovation, wind solar complementary off grid power supply system projects have low investment costs, short delivery cycles, simple and convenient maintenance, and have achieved good economic and social benefits for our customers.
