China Three Gorges Renewables (Group) Co., Ltd.

Revenue comes almost entirely from selling generated electricity to grid companies, split between prices set through a guaranteed regional purchase mechanism and prices set through market trading, so total revenue moves with both how much electricity is generated and where the average settlement price lands. The business has posted a profit every year for which figures are available.

It scales the way a fixed-plant conversion business does: growth comes from building and connecting new wind, solar and storage sites one project at a time, each adding output within a physical ceiling, rather than from network effects or low-capital replication. That kind of expansion is capital-intensive, and CompanyGraph reads its debt levels and debt relative to operating cash flow as running high, consistent with continued build-out funded largely through borrowing.

Its own account names a small group of state-linked construction and engineering firms, including its own controlling parent group, as key suppliers for building its generation sites, and identifies wind and solar resource availability at chosen sites as the basic input the business depends on. It also depends on grid, dispatch and market-trading bodies it does not own to move and settle what it produces, and flags continued access to land and high-quality resource sites as a condition for future growth.

A small number of power-grid and regional electricity-distribution companies are its direct buyers, with one of them alone taking the large majority of its sales. Beyond them, it separately identifies broad categories of downstream users, including heavy industry and data centres, as the eventual consumers of that electricity, though those end users are not its own direct customers.

The company describes its own edge as access to high-quality wind and solar sites, in-house construction and engineering management, financing capacity and accumulated operating experience, and its own figures show a national market share that is markedly higher in offshore wind than in onshore wind or solar. At the same time, CompanyGraph classifies the underlying business, converting a physical input into output within a fixed throughput ceiling, as a very common way of operating among a large set of similar companies, so the evidence does not support a claim that its approach cannot be replicated by others running the same kind of system.

The industry-level pattern for this kind of business is a limit set by how much a fixed conversion process can put through at any one time. In its own words, this company's practical limit sits one step earlier and one step later than that: how much high-quality wind and solar site access it can secure to build on, and how much of what it generates the surrounding grid, peaking and transmission system can actually absorb and let it sell, both described as conditions the company does not fully control.

Its own disclosures show the very large majority of sales running through a small handful of grid-company buyers, with a single buyer alone accounting for most of it, and the company names policy and market-price shifts as the risk it lists first, having already reported a revenue fall tied to both softer generation and a lower average settlement price. Separately, CompanyGraph's own recalculation of the reported figures shows debt running high relative to assets and to operating cash flow, alongside a receivables balance that is both a large share of current assets and one that keeps growing, so counterparty concentration and price exposure sit alongside a balance sheet already showing signs of strain.

Its own risk disclosures put policy and electricity-market pricing changes at the top of the list, ahead of customer concentration, resource access, and project execution and safety risk, and name the national economic-planning and energy regulators, together with guaranteed-purchase and pricing rules set at the national level, as the rules its revenue operates under. It also discloses exposure to legal disputes tied to its project sites and carries a modest amount of foreign-currency cash, receivables, investments and borrowings that add currency exposure on top of that domestic regulatory exposure.
