Chongqing Three Gorges Water Conservancy and Electric Power Co., Ltd. (600116.SS): Mission and Values

• Core installed hydropower capacity: 750,000 kW (combined across the company's portfolio of hydropower stations).
• Thermal power assets: multiple thermal-generation units providing fuel‑based electricity to complement hydro output and ensure supply stability.
• Manganese business: manganese ore mining and electrolytic manganese production integrated into the industrial segment to diversify revenues and capture value along the supply chain.
• Grid assets: ownership and operation of 9 × 110 kV substations and 19 × 35 kV substations for transmission and distribution.
• Engineering & services: electrical and mechanical equipment installation, maintenance, commissioning; construction of water conservancy and hydropower projects.

• Electricity sales: generation from hydropower and thermal plants sold via power purchase agreements or on-market trading; hydropower offers lower marginal cost and seasonal peak value.
• Grid fees & services: ownership of substations enables transmission service income, connection fees, and compensation for ancillary services (voltage support, frequency regulation).
• Mining & processing proceeds: sale of mined manganese ore and electrolytic manganese metal to steel and battery-material customers; downstream processing captures higher margins.
• Engineering & contracting revenue: design, construction, installation, and maintenance contracts for third parties and internal projects provide fee-based cash flow and reduce capital project costs.
• Project development: construction of new water conservancy and hydropower projects increases future generation capacity and long-term contracted cash flows.

• Capacity utilization: hydropower output varies with river flow and seasonal reservoirs; thermal plants dispatched to meet demand gaps or during low-water periods.
• Fuel & commodity exposure: thermal generation margin depends on coal/oil prices; manganese margins depend on ore prices and electrolytic processing costs.
• Asset reliability: ongoing electrical & mechanical maintenance and commissioning services reduce downtime and extend equipment life, improving return on assets.
• Regulatory and environmental factors: water resource management, environmental approvals for mining and thermal emissions, and grid access policy materially affect operations and capex planning.

• Increase in hydropower dispatch during wet years raises low‑cost generation revenue and reduces fossil fuel burn.
• Higher manganese metal prices or improved beneficiation/process efficiency increases industrial segment margins.
• Expansion of substation footprint or sale/lease-back of grid assets can monetize infrastructure while maintaining operational control.
• Winning EPC contracts and providing long‑term maintenance raises recurring service income and utilization of in‑house teams.

Chongqing Three Gorges Water Conservancy and Electric Power Co., Ltd. (600116.SS): How It Works

• Primary revenue: sale of electricity from hydropower stations and thermal power plants to industrial, commercial and residential customers via long‑term and spot contracts.
