REGULATORY REFERENCES
Referencia normativa: Belgium
Regulatory framework of Belgium · Directive (EU) 2024/3019: reported-capacity band 10,000 to 149,999 p.e.; obligations are set by agglomeration load, not by the capacity of this plant. Individual applicability is not determined in this profile.
SCENARIO
Reference energy scenario for this load estimate · simulator engine
what this estimate is · Inputs: 18,500 p.e. of reported load; equivalent average load 18,487 p.e. with the reference profile of Belgium (hypothesis with reported load and reference profile; not a measurement). Open this scenario in the simulator · how it is calculated and what it is not.
Reference scenario computed on the server from the reported load and the country profile; an estimate, not a measurement. The simulator recomputes it when opened.
WATER THAT COULD RETURN
