Huaneng's Coal Bill Rose 4.6% and Its Tariff Fell 2.3% — the Pass-Through Isn't Linear

Huaneng's Coal Bill Rose 4.6% and Its Tariff Fell 2.3%

Huaneng Power International has a simple business: burn coal, sell electricity, keep the spread. In the first nine months of 2026 that spread was squeezed from both ends. Consolidated operating revenue under IFRS came to CNY 165.85bn, down 4.12% year on year, while net profit attributable to shareholders collapsed to CNY 7.82bn — a 47.29% decline — for EPS of CNY 0.39. On-grid sales fell 5.6% to 312.9bn kWh and the average realised tariff fell 2.32% to CNY 467.63/MWh. Meanwhile the standard coal price at domestic plants rose 4.62% to CNY 933.55 per tonne.

That combination — lower volume, lower price, higher input cost — is not a normal utility story. It is a market-design story, and management told it, somewhat reluctantly, in the Q&A.

The pass-through that only half works

The obvious analyst question was why a coal-heavy generator cannot recover a rising coal price in its tariff. Management first asserted it can: “We can draw the conclusion that the coal price increase has been passed through to the tariff side, and we can draw this conclusion from the tariff of the company in the third quarter, as well as those publications of the monthly settlement tariff in October.” — Guoyun Li, Management / IR Representative · 2026-10-28 Minutes later, pressed on the mechanics, the same speaker conceded the opposite in substance: “The increase of coal price cannot be fully passed through towards the tariff channel. It's not a linear relation.” — Guoyun Li, Management / IR Representative · 2026-10-28

Three frictions were named. First, the regulatory framework caps settlement prices in some provinces. Second, and more damaging this year, the long term contract book was signed too cheaply — management repeatedly referred to a larger year-on-year decline in the yearly signing price for 2026, so cost recovery had to be routed through the spot and monthly market instead. Third, the long-term coal supply itself did not show up: only 55.95m tonnes of contract coal was procured through September, down 12.6%, covering just 43.8% of consumption — 40.79% in the third quarter alone — because, in management's blunt phrasing, suppliers short on coal price upside have little will to honour fixed-price contracts.

The result is a coal fleet running on fumes rather than fuel. Coal-fired profitability per megawatt hour was CNY 28.6/MWh for the nine months, and 43.7% of coal-fired units were loss-making in the third quarter, up roughly 10 percentage points quarter on quarter. Q3 coal-fired net profit was CNY 662m against CNY 1.48bn from the PV sector and CNY 886m from wind.

Your own renewables are the competitor

Here is the part worth the price of admission. Under China's Document No. 136, this is the first year renewables have been dispatched into the spot market at full capacity — and the effect, in management's own words, has been to grow revenue without growing profit:

This year marks the very first year that the Document No. 136 has been implemented, that the renewable sectors has joined the spot market at a full capacity... the generation of the renewables and the revenue of the renewables has increased, but the profitability and efficiency haven't been improved.

The mechanism is cannibalisation, and management stated it cleanly: “the coal-fired units does not have a marginal contribution when the renewable power generators delivers a higher production.” — Guoyun Li, Management / IR Representative · 2026-10-28 In a spot market cleared by marginal cost, midday solar output drags the clearing price toward zero while coal units, which must run to be compensated, only earn during peak and balancing hours. The renewable sector is simultaneously Huaneng's growth engine and the thing depressing the price its legacy fleet sells into. That is a genuinely awkward structural position, and it is new for this company — earlier in the year the story was simpler: cheap coal, better spreads.

Green shoots do exist inside that trap. PV produced a positive marginal contribution of about CNY 148m in Q3 as generation rose 870m kWh quarter on quarter and the PV tariff ticked up CNY 1.5/MWh to CNY 372.4/MWh. Only 7.7% of PV capacity was loss-making over nine months — a sharp improvement on the roughly 30% flagged at the interim. Wind profitability per MWh was CNY 108.5/MWh, up about CNY 20 year on year, as the per-MWh cost fell CNY 17 to CNY 313.6/MWh. The nine-month curtailment rate of 11% also beat the 13% seen in the first half. Management's read is that renewable tariffs are “experiencing its bottom and we believe that it will see a rebound in the near future.” — Guoyun Li, Management / IR Representative · 2026-10-28

What the call stopped talking about

Two silences matter more than anything management said. The first is the dividend. Asked directly whether the payout ratio per share would stay stable, the answer was evasive: “Company made our dividends payout plan based on the earnings per share. What you mentioned, the fixed dividends payout ratio is not our consideration.” — Guoyun Li, Management / IR Representative · 2026-10-28 With EPS down sharply, "based on earnings per share" is not reassurance — it is a warning dressed as policy.

The second is the minority interest leak. Q3 net profit of roughly CNY 1.23bn split with CNY 899m going to minorities — 42.11% — because the most profitable coal plants sit in partially owned subsidiaries. Management confirmed the skew is “largely impacted by those profitability of coal-fired units in the third quarter... because that equity share in different coal-fired plants of the company.” — Guoyun Li, Management / IR Representative · 2026-10-28 The parent is collecting a shrinking share of the coal recovery it is paying for.

Also quietly fading: Tuas Power, the Singapore arm that was a headline theme last quarter, dropped down the keyword ranking this quarter even though its CNY 1.12bn EBIT was disclosed in the prepared remarks. And power generators remains the top substantive theme — but the conversation around it has shifted from capacity growth to capacity economics. To be fair to the company, the structural story is intact: 5.16 GW added year to date (3.93 GW wind and solar, 1.23 GW gas), 160 GW under control, 42.92% clean energy, about 10 GW of renewables under construction and a CNY 22.98bn subsidy receivable that is at least no longer growing.

The 2027 contract is the whole ballgame

Everything now hinges on the annual long term electricity contract signings for 2027, and management was explicit that no national or provincial guidance exists yet. Their three factors — NDRC policy, fuel cost, and the company's own settlement strategy — resolve to a forecast of a slight increase in the signing price, with coal units increasingly positioned as capacity based compensation providers rather than energy sellers.

One analytical caveat for anyone parsing this call: the interpreter renders san ji du (Q3) as "the first quarter" throughout, and much of the Chinese audio was untranslated, which is why a keyword like English content tops Huaneng's own trajectory this quarter. The numbers, however, reconcile — they are third-quarter and nine-month figures, not Q1.

The verdict: Huaneng is not a coal-recovery story any more. It is a company whose own green build-out has begun to compete with its thermal fleet inside a spot market designed to reward the lowest marginal cost, while a cheap 2026 contract book blocks cost recovery and minorities absorb the profits that remain. Until the 2027 contracts are priced — and until someone explains how the payout ratio survives a 47% profit decline — the equity is a policy option, not a utility.
