Biomass co-firing technology is a potential solution for low-carbon transition of coal-fired power plants. Existing techno-economic analyses this fail to consider indirect benefits, such as avoided losses from retrofitting, and the heterogeneity across regions. To address these limitations, we developed five types indicators analyze six possible future scenarios application in 29 provinces China, based on regional heterogeneous data. The results show, first, generally, higher local coal price, on-grid electricity biomass feed-in tariff subsidy, carbon trading greater incentives benefits co-firing. Second, bio-electricity subsidies greatly increase with 26 analyzed having sufficient retrofits scenario. Third, has more revenue when emission quota limited than it's not. Our indicate that timely tightening CO2 quotas sector will stimulate technological even without additional policy incentives, while plants retrofitted achieve positive returns incentives.
