Table 5 Overview of key results from simulated flexible and non-flexible bioenergy power generation in the case study

From: Impact of flexible bioenergy provision on residual load fluctuation: a case study for the TransnetBW transmission system in 2022

  Year 2022
NO-BE NON-Flex-BE Flex-BE
Renewable share (REN share) 26.8% (other renewables) 34.9% (other renewables + non-flexible bioenergy) 35.0% (other renewables + flexible bioenergy)
Variance in daily residual load 100% 70% (reduced by 30%a)
Maximum positive RL (deficit power) 10,440 MW 9801 MW (100%) 9458 MW (reduced by 4%a)
Minimum negative RL (excess power) - 1965 MW - 2604 MW (100%) - 2362 MW (reduced by 11%a)
Hours of negative RL 42 h/a 98 h/a 70 h/a
BE power production in times of negative RL 44.1 GWh/a 26.5 GWh/a (reduced by 40%)
Avoided BE power production in times of negative RL 17.6 GWh/a
