Yunnan Aluminium — LME Aluminium Cycle

Yunnan Aluminium is one of China's largest aluminium smelters — benefiting from Yunnan province's abundant hydroelectric power to produce green aluminium at significantly lower energy costs than coal-powered smelters in northern China. Listed on SZSE, Yunnan Aluminium is unique in the Chinese aluminium industry for its hydro-power advantage — creating a structural cost advantage that converts to extraordinary margin expansion when LME aluminium prices are high.

Hydropower Advantage: Green Aluminium Premium

Aluminium smelting is extremely energy-intensive — producing one tonne of aluminium requires approximately 13,500 kWh of electricity. Yunnan's hydropower (primarily from the Lancang-Mekong river cascade) provides electricity at significantly lower cost than coal-fired power used by northern Chinese aluminium producers. This energy cost advantage creates a structural margin differential that grows wider when electricity prices rise. Yunnan's hydro aluminium is also classified as 'green aluminium' — attracting premium pricing from sustainability-conscious buyers.

Hydropower Seasonality: The Operational Risk

Yunnan's hydropower availability is highly seasonal — wet season (May-October) provides abundant low-cost power; dry season (November-April) can create power shortages that force production cuts. Yunnan province has experienced significant production curtailments during drought years when hydro reservoir levels are critically low. This seasonal and climate-driven production variability creates earnings volatility beyond LME price cycles.

LME Price Leverage

At LME aluminium above $2,500/t, Yunnan Aluminium's hydro-based cost advantage translates into exceptional margins — with cash costs approximately $300–500/t below coal-based producers. This leverage to high LME prices makes Yunnan Aluminium one of the most operationally geared aluminium plays globally. When LME rises, the marginal cost producers are northern Chinese coal-smelters — Yunnan's margin expands proportionally.

Capacity Expansion

Yunnan Aluminium has been expanding capacity as hydro power availability grew and aluminium demand increased. New smelter capacity in Yunnan has been a key driver of China's aluminium production growth. However, expansion creates supply that can cap LME price upside — requiring investors to monitor the pace of Yunnan smelter additions carefully.
