Green Electricity Is Moving into the Operating Model

A September 7 report marking five years since China launched its green-power trading pilot offered a useful picture of how renewable electricity is entering ordinary commercial decisions. By August 25, green-power trading in the Mengdong grid had exceeded 8.6 billion kilowatt-hours, up 77.47% from the previous year’s full-year volume. Southern Hebei had passed 10 billion kilowatt-hours by August 21, more than double its 2025 full-year level, while Fujian’s January–July green-power trading reached 1.895 billion kilowatt-hours and interprovincial volume was about ten times the level of the same period in 2025. These figures are reported market activity, not proof that every buyer has decarbonized its products.

The significance is that green electricity is moving from a voluntary environmental purchase toward a production input. The report notes that early demand came mainly from multinational, export-oriented and ESG-conscious users. Demand is now increasingly linked to export competition, product carbon-footprint management and access to some markets. That changes the procurement question. A buyer needs more than a certificate or a broad renewable claim; it needs to know what was purchased, where it was generated, how it was settled and how the environmental attribute is allocated to a facility or product.

China’s market rules are catching up with that demand. Green electricity became a national trading category in the medium- and long-term power market framework, and the market has developed combinations of multi-year or annual volume commitments, monthly adjustments, spot or rolling matching and green-certificate support. Shanghai’s first intra-city hourly transaction, reported in the same period, traded 420,000 kilowatt-hours and provided hourly consumption credentials and an accounting list. The transaction involved Baosteel and Shenergy among its participants. Hourly matching is still an emerging mechanism, but it shows where the evidence burden is going: from annual claims toward more granular matching between use and supply.

That direction brings both value and friction. Physical renewable supply is unevenly distributed, transmission capacity constrains cross-regional delivery, and green electricity and green certificates can move with different levels of liquidity. The national report describes price differences and the difficulty of making the environmental value transparent. These are market-design issues, but they become corporate-control issues when a company promises customers that a product is made with renewable electricity. The contract, meter, settlement record, certificate transfer and allocation method must tell the same story.

Manufacturers should therefore separate three questions. First, how much renewable electricity did the facility actually consume under the applicable accounting rules? Second, what environmental instruments were purchased, and what claims do they support? Third, what portion can be assigned to a particular product, customer or reporting boundary without double counting? A green-power contract can be commercially useful while still being insufficient for a product carbon-footprint claim. The answer depends on the relevant standard, the customer’s rulebook and the quality of the evidence.

The transition also changes the role of the consumer. The China Energy News report quotes market participants describing a move from buying electricity to building or arranging supply, including green-power direct connection, local consumption, distributed aggregation and source-grid-load-storage integration. Not every company should own generation. The broader point is that large users may manage their electricity exposure through demand response, load shifting, long-term procurement and cooperation with developers. This makes energy strategy part of operations and finance, not simply a sustainability-office initiative.

Investors should read growth in trading volume with two lenses. The first is additionality and credibility: what does the transaction actually change in the power system and in the company’s accounting? The second is resilience: can the company secure a reliable supply at a manageable cost when renewable output, grid constraints and rules change? The market is becoming more useful, but its value will depend on traceability and the ability to connect environmental attributes with physical and commercial reality. Green electricity has entered the operating model; governance must now catch up with the transaction data.

The next phase will be less about proving that demand exists and more about proving that the product can be delivered consistently. Procurement teams will need scenario plans for curtailment, price changes, transmission limits and customer-specific accounting. Sustainability teams will need to understand the commercial contract rather than rely on a certificate name. Finance teams will need to decide how a long-term green-power commitment affects cost and risk. That cross-functional work is what turns market growth into transition capability.
