Table 4 Technical parameters for the flexible operation from cluster 1 and cluster 2 bioenergy plants
Bioenergy technologies | ||
|---|---|---|
Cluster 1 (solid biomass) | Cluster 2 (biogas, liquid biofuel CHP) | |
Modulation of power output | m (t)cluster 1 = 0.5–1.2 in 2-h time steps | m (t)cluster 2 = 0–1.0 in 1-h time steps |
Operational constraints | • Constant daily energy production | • Constant daily energy production |
• No storage limitations for input materials affecting operation | • On-site biogas storage equivalent to 12–24 h in biogas production | |
• Reduced daily production (−66%) during summer from April to October | • Reduced bioenergy production (−38%) on weekends assuming feeding management | |
Energy production | Annual energy production (AEP) remains constant for either non-flexible or flexible operation. AEP from biomass in 2022 taken from [NEP 2022B] | |
