A national obligation
The CPSSP / SAGESS system
In metropolitan France, each oil operator individually fulfills its storage obligation by constituting its reserve stocks on the one hand (44% or 10% as it chooses) and, on the other hand, by delegating the rest ( 56% or 90%) to the Professional Committee for Strategic Oil Stocks (CPSSP), which uses physical stocks of SAGESS and stock leases with purchase options in France and abroad to fulfill its mission.
