SCENARIO
Reference energy scenario for this load estimate · simulator engine
what this estimate is · Inputs: 15,200 p.e. of reported load; equivalent average load 11,856 p.e. with the reference profile of Norway (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
