China’s first regional electricity market moved into formal operation on 24 October. The Southern Regional Electricity Market links Guangdong, Guangxi, Yunnan, Guizhou and Hainan after more than a year of continuous settlement trials. [2] The National Energy Administration said the next stage should strengthen integration between cross-provincial and provincial markets, improve disclosure and monitoring, and expand market access in an orderly way. [1]
The change is an operating-status milestone, not the launch of trading from zero. The five-province market was already clearing transactions, supporting dispatch and settling participants during its trial. [4] Formal operation signals that regulators have moved the regional mechanism beyond the testing stage; it does not create one uniform southern electricity price or give every user and flexibility asset immediate access. [3]
The market was already operating at scale
The continuous settlement trial began in June 2025 after earlier dispatch and settlement tests. At that point, the regulator described the system as the first continuously operating regional market to cross provincial administrative boundaries. It covered all five southern provinces and regions, had more than 220,000 registered participants and traded about 3.8 billion kilowatt-hours a day. [4]
Meeting data reported by Xinhua show the size of the system entering formal operation. From January through September 2026, the market traded nearly 900 billion kilowatt-hours, more than 70% of electricity sold across the Southern Grid. Maximum daily clearing exceeded 4 billion kilowatt-hours and registrations passed 290,000. The report also said 40% of incremental electricity sales came from new energy, regional renewable utilisation remained above 95%, and 19.4 billion kilowatt-hours traded across the Southern Grid and State Grid operating areas during the trial. [2]
Those numbers demonstrate reach, but they do not isolate the market’s causal effect on renewable output or utilisation. Weather, grid construction, demand and administrative arrangements also matter. The stronger conclusion is narrower: the market has operated at scale across multiple power systems and technologies before regulators made continuous regional clearing the normal operating state.
One region does not mean one tariff
The issued 2025 V1.0 trial rules describe a layered market. Cross-provincial and provincial medium- and long-term trades operate independently with an orderly connection, while their spot transactions use joint clearing and coordinated operation. Spot trading runs from the day before physical delivery through real time, and the rules use nodal marginal pricing. [3]
Joint clearing therefore does not mean that every province, node or hour receives the same price. For large power users, generators and retailers, the practical effect is a stronger link between regional constraints, provincial contract positions and settlement. Procurement teams need to reconcile medium- and long-term positions, load forecasts and actual consumption rather than treat annual electricity purchasing as a fixed-price exercise.
Access remains conditional
The operating rules cover eligible generators, retailers and electricity users, along with new participant types including distributed generation, storage and virtual power plants. Participation still requires registration, technical capability and compliance with the relevant provincial arrangements; other participant types must meet the technical conditions for the spot market. [3]
The 24 October announcement preserves that boundary. It calls for orderly expansion of market scale and openness, alongside stronger disclosure, monitoring and risk control. [1] Storage developers, virtual power plants and flexible industrial loads may gain broader routes to market, but the announcement is a direction of travel rather than evidence that every class already bids and settles on identical terms. [2]
The environmental value is therefore conditional. A regional market can make congestion, surplus power and flexibility more visible, helping renewable-rich provinces serve distant demand and rewarding resources that respond when the system is tight. It does not by itself make every traded megawatt-hour green or prove a company’s electricity claim. Buyers still need credible contracts, certificates and consumption records. What changed on 24 October is the status of the infrastructure beneath those decisions: the regional market has moved beyond continuous settlement trials into formal operation. [1]
