Method & Evidence

AimWhat are the technical and economic implications of a biogas plant providing positive secondary control energy reserves?
MethodSimulation and Techno-economic Assessment
ProcedureA detailed simulation model of a biogas plant was developed. Ex-post simulations of one year of flexible operation were conducted to assess the plant's ability to provide control energy reserves alongside biomethane production. Profitability was analyzed based on control energy market prices and start-up costs, with a cost efficiency analysis for heat storage investment.
