Actual losses are calculated as the difference between injections (generation injected + physical imports) and extractions (consumption extracted + physical exports) at the terminals of the public transmission system.
The calculation process is aligned with the flow reconstitution process. The losses for a given month M are calculated at the deadlines M+3, M+6 and M+12. Newly available data are published on the 15th of each month.
E.g. on 15/09/2007, the values M+3 from May 2007, M+6 from February 2007 and M+12 from August 2006 are published on the website.
They are made available to players in the tables below.
