REGULATORY REFERENCES
Referencia normativa: France
Regulatory framework of France · Directive (EU) 2024/3019: reported-capacity band 1,000 to 9,999 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: 1,214 p.e. of reported load; equivalent average load 1,214 p.e. with the reference profile of France (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.
