Shanghai Electric Power Co., Ltd. (600021.SS) - BCG Matrix Analysis: Dogs

Legacy small coal units face phaseout. Older coal-fired units under 300MW now contribute 2.7% to total company revenue (RMB 4.1 billion of RMB 152 billion FY). Segment market growth is -6% year-on-year driven by environmental regulations and carbon pricing averaging RMB 80/ton CO2. SEP's market share for these legacy units has fallen below 2% of the national small-coal capacity market. After mandatory environmental retrofits and carbon credit purchases, operating margins for this cohort stand at -3%. All capital expenditure for life-extension has been halted; FY impairment charges recognized on these units totaled RMB 1.02 billion.

Inefficient biomass power plants struggle for viability. The biomass segment generates approximately 2.0% of SEP's revenue (RMB 3.0 billion). Market growth is essentially flat at ~1% annually due to limited feedstock supply and policy uncertainty. SEP's share in the biomass market is under 4% regionally. Feedstock cost inflation has driven levelized cost of electricity (LCOE) for these plants to RMB 520/MWh versus the company weighted average procurement rate of RMB 380/MWh. Return on investment for this segment is around 2%, substantially below SEP's weighted average cost of capital of 7.5%. CAPEX for new biomass projects has been set to zero; management is evaluating divestment, repowering to hybrid configurations, or fuel-switching.

• Revenue contribution: 2.0% (RMB 3.0bn)
• Market growth: 1% YoY
• SEP market share (biomass): <4%
• LCOE: RMB 520/MWh
• ROI: 2% vs WACC 7.5%
