en.Wedoany.com Reported - Nanjing's Virtual Power Plant (VPP) management platform has connected 20 operators, aggregating over 4,300 users, with a declared regulation capacity of 300,000 kilowatts, equivalent to a large peak-shaving power plant. As Jiangsu's electricity spot market enters a 15-minute dynamic pricing phase in 2026, the Nanjing VPP is exploring new pathways for grid supply security and energy transition through a light-asset model.
In 2024, Nanjing established the first government-authorized VPP management center within the State Grid's operating area, providing platform access and capability certification services for operators. Without building power generation units or factories, the VPP aggregates resources such as Automotive Industry" target="_blank">New Energy Vehicles, energy storage equipment, and distributed photovoltaics through big data and AI algorithms, enabling unified dispatch and market trading, and supporting an operational model of "storing during low demand and discharging during high demand, ensuring flexible supply."
To meet the same peak electricity demand, traditional power grid construction requires an investment of approximately 400 billion yuan, while the VPP model only needs 50 to 60 billion yuan, reducing costs to one-seventh of the traditional model. Ma Jinjie, Deputy Director of the Marketing Service Center of State Grid Nanjing Power Supply Company, stated: "The VPP is like a 'Didi platform' in the energy sector. It doesn't build physical power plants itself but efficiently aggregates scattered power resources to participate in electricity market trading and grid regulation."
The promotion of VPPs is shifting electricity consumption from passive use to active profit-making. Nanjing has launched V2G (Vehicle-to-Grid) pilot projects, allowing new energy vehicle owners to charge during low-price periods and discharge to the grid during peak periods, earning revenue from regulation services, with a maximum earning of 0.85 yuan per kilowatt-hour.
At the industrial park and enterprise level, VPPs optimize electricity usage timing based on 15-minute dynamic price signals, guiding enterprises to consume electricity during low-price periods and discharge during high-price periods, helping energy-intensive enterprises save millions of yuan in electricity costs annually. The Nanjing Jiangning Development Zone's Energy-Carbon VPP has aggregated 45 enterprises, with a regulation capacity of 395,000 kilowatts, enhancing the region's green electricity consumption capacity.
Leveraging its smart grid industry foundation, Nanjing is accelerating the marketization of VPPs. Among the first 100 VPP projects in Jiangsu Province, Nanjing accounts for 10. The related technical systems and operational models are gradually being promoted nationwide, providing reference solutions for China's energy transition and the construction of a new power system.
