en.Wedoany.com Reported - On June 27, the technical tour of the "Global South" Electric Power Partnership Development Forum was held in Shenzhen. Representatives from the electric power industry of 18 countries and regions, including Asia, Africa, and South America, visited the 110kV Chunhui Substation built by the China Southern Power Grid Shenzhen Power Supply Bureau, the Shenzhen Lianhuashan Ultra-Fast Charging Station, and the CSG Energy Storage Company's Shenzhen Pumped Storage Power Station, experiencing firsthand the new achievements of China's electric power industry in green and low-carbon development.
The delegation's first stop was the 110kV Chunhui Substation, adjacent to the Shenzhen Bay Sports Center. As the nation's first zero-carbon smart science education substation, it integrates multiple energy-saving, carbon-reducing, and digital technologies. The science education exhibition hall within the substation, themed "Electricity Drives the Urban Future," vividly showcases the history of Shenzhen's economic and social development empowered by electricity through a format combining "open landscape + immersive science education." Foreign representatives commented after the visit that this substation, which blends energy science education with urban culture, serves as an excellent window for communication between urban energy and the public.
Subsequently, the delegation visited the Southern Power Grid Shenzhen Lianhuashan Ultra-Fast Charging Station, the nation's first diversified comprehensive demonstration station integrating "solar storage, ultra-fast charging, vehicle-grid interaction, and Power Harmony." As one of the benchmark stations in Shenzhen's "City of Ultra-Fast Charging" initiative, it offers car owners an ultra-fast charging and discharging experience of up to "one kilometer per second." A live demonstration of the V2G (Vehicle-to-Grid) system allowed foreign guests to witness how electric vehicles can transform from mere power consumption terminals into "mobile power banks" supporting grid resilience. The station is also equipped with photovoltaic panels and energy storage, creating a coordinated "source-grid-load-storage" energy ecosystem.
In 2025, the Lianhuashan Ultra-Fast Charging Station's total charging volume exceeded 7.8 million kWh, serving an average of approximately 500 vehicles per day. Through green electricity trading and other means, it achieves 100% green power supply. Additionally, the station has repeatedly participated in demand-side response for virtual power plants, effectively playing a regulatory role. "In Thailand, the adoption of electric vehicles is continuously increasing. Comprehensive stations like the Lianhuashan Ultra-Fast Charging Station offer valuable reference for our development," said Mr. Jaturong Sirimaneewattana, Assistant Governor of the Electricity Generating Authority of Thailand, after the visit.
Overlooking the rippling reservoir and the distant city skyline, the scenic landscape of mountains and clear waters was pleasing. At the Shenzhen Pumped Storage Power Station, the delegation expressed great admiration for this green power station "hidden" within the city, which integrates pumped-storage power generation, urban water supply, and ecological landscape functions.
Located between Yantian District and Longgang District in Shenzhen, only 20 kilometers from the city center, the station has an installed capacity of 1,200 MW. It is the nation's first large-scale pumped storage power station built in an urban center. The station comprises upper and lower reservoirs. It pumps water for storage during low electricity demand and releases water to generate power during peak demand, acting as a "regulator" for grid power balance. It undertakes critical tasks such as peak shaving and valley filling, frequency and voltage regulation, black start, and emergency backup, with its regulation capacity covering nearly one-third of the peak shaving demand of the Shenzhen power grid. This station is also the first pumped storage power station under the Southern Power Grid where the main equipment was supplied by a Chinese manufacturer, marking a significant milestone in China's pumped storage industry's journey from following to leading.
In recent years, in accordance with the arrangements of the China Southern Power Grid, CSG Energy Storage Company has actively implemented the national initiatives for high-quality Belt and Road cooperation and the "Two Corridors and One Belt" framework. It has strengthened exchanges and cooperation with advantageous power enterprises from countries such as Vietnam, Cambodia, and Chile, and assisted in hosting major conferences like the Lancang-Mekong Regional Electric Power Technology and Standards Exchange Meeting and the Annual Meeting of the International Council on Large Electric Systems (CIGRE). These efforts fully demonstrate the company's advanced management concepts and technical strengths. Over the past three years, it has led and undertaken multiple research tasks on pumped storage construction, operation, and management, contributing to international business expansion and cultural exchange, and promoting the "going global" of pumped storage technology, equipment, services, and standards.
From "building consensus" at the Hong Kong forum to "on-site joint verification" in Shenzhen, the China Southern Power Grid is willing to share replicable green power development experiences accumulated in the construction of a mega-city power grid with "Global South" partners. In the future, the China Southern Power Grid will continue to adopt an open attitude, facilitating regional connectivity and making green energy a solid bond connecting the common development of "Global South" partners.
