This basically looks like a supply / demand graph (although with the price/quantity axes inverted).
I am guessing a VIM is 1 manufacturing plant (or furnace). The green line is demand which naturally drops off as prices get higher. The blue lines are supply (capacity) which naturally increase as prices get higher.
I would read this as there is excess supply to meet current demand based on expected prices - 3 VIMs at 75K = ~215K of capacity to meet 80K of demand at P=7 (current prices). Alternatively it could mean the 3 VIMs = 75K of capacity (more likely) in which case this a slight supply deficiency to meet current demand.
There will also be an significant increase in demand but supply capacity will only be brought online to meet this increase at a price of 12
