| Abstract | Wind and
solar power are already the major pillars of renewable power generation in
Germany and will become even more dominant in the future. At the same time,
dispatchable power plants phasing out. The expected increase of fluctuations in
the residual load could be partial balanced by flexible bioenergy. However,
there is currently no assessment approach for quantifying the systemic GHG
impacts for flexible bioenergy generation. Based on the merit order concept, we develop an empirical approach to systemically assess the GHG emissions impact for electricity generated by flexible bioenergy plants. We estimate price response functions using the historical data of market prices and feed-in time series for the different forms of dispatchable non-renewable dispatchable generation (NRDG). By calculating the expected NRDG based on these functions, and using specific emission factors, we are able to estimate the net impact for a switch from invariable to flexible bioenergy generation. The calculated net impact ranges from −20 to −36 g CO2eq per kWh, which is equivalent to a benefit of −10% to −18% respectively for an average carbon footprint of 200 g CO2eq per kWh. The calculation tools are written in Python and freely accessible on ZENODO and GitLab. |
