Özet

This study evaluates bioenergy-based electricity generation in Türkiye within the technical screening logic of the European Union (EU) Taxonomy. A hybrid framework combines national electricity-sector data, life-cycle greenhouse-gas (GHG) evidence, Best Available Techniques (BAT), and comparative assessment of the EU Taxonomy, Turkish Environmental Impact Assessment (EIA) legislation, and Türkiye Sustainability Reporting Standards (TSRS 1 and TSRS 2). For biogas-to-electricity systems, a normalized 1 kWh mass-energy balance was developed for animal-waste and agricultural-residue feedstocks under conventional (35% electrical efficiency) and BAT-level (43%) operation. Required biogas volume decreases from 0.440 to 0.358 Nm³/kWh for animal-waste biogas and from 0.519 to 0.423 Nm³/kWh for agricultural-residue biogas. The corresponding physical stack CO₂ falls to about 459 g/kWh at BAT efficiency; this value is biogenic and is not the life-cycle metric used for Taxonomy alignment. Using the 183 g CO₂-eq/MJ fossil comparator and the 80% GHG-saving requirement applied in the study gives a maximum life-cycle intensity of 131.76 g CO₂-eq/kWh. Literature values of 16–74 g CO₂-eq/kWh indicate strong compliance potential for well-managed pathways. A mass-balanced national scenario, recalculated from the 2023 baseline data to impose exactly 10% bioenergy generation by displacing lignite, reduces the consumption-point grid factor from 469 to approximately 382 g CO₂-eq/kWh (18.6%). Full alignment nevertheless depends on feedstock sustainability, methane control, life-cycle accounting, DNSH safeguards, BAT performance, and consistent environmental and corporate reporting.
