Taiwan's Power Emission Factor Drops to 0.467; Ministry of Economic Affairs: Energy Transition Progressing

Central News Agency, Taipei, June 2. The Energy Administration of the Ministry of Economic Affairs announced today that the 2025 power emission factor for public electricity retailers is 0.467 kg CO2e/kWh, a 1.5% decrease from 2024 and approximately 12% lower than in 2016. The MOEA stated that the continuous decline in this factor reflects concrete progress in the government's promotion of energy transition, expansion of low-carbon power supply, and optimization of the thermal power structure. The power emission factor measures the amount of carbon dioxide emitted per kilowatt-hour of electricity generated. The MOEA stated in a press release today that in recent years, to meet international supply chain green power demands, industries have purchased more green electricity through various channels. Starting in 2025, the MOEA will divide the power emission factor into an 'Industrial Power Emission Factor' and a 'Residential Power Emission Factor.' The 'Industrial Power Emission Factor' is 0.466 kg CO2e/kWh, intended for use by enterprises when auditing and disclosing emissions to help industries align with international decarbonization requirements. The 'Residential Power Emission Factor' is 0.471 kg CO2e/kWh, applicable to residential use. The MOEA explained that the public electricity retailer emission factor mainly calculates the emissions per unit of electricity sold by the Taipower system. The national power emission factor, on the other hand, incorporates private green power transactions, including direct and wheeling renewable energy, to present a more complete picture of national electricity consumption emissions. The MOEA estimates that the 2025 national power emission factor could drop to 0.456 kg CO2e/kWh, a decrease of about 14% compared to 2016. The MOEA noted that facing growing electricity demand from semiconductors, AI, and data centers, the power system must continue to expand renewable energy construction and rely on low-carbon gas-fired units for stable dispatch. These constructions are essential foundations for ensuring power supply stability, increasing system resilience, and lowering emission factors. The ministry hopes for continued support from all sectors to jointly promote energy transition and net-zero goals.
