I am NO expert on what controls the price of propane. I do know that there is a record amount of fracking wells, using a record amount of water that is then a hazmat chem. MB had the numbers on the increase %, and I forget but it was crazy high.
We are doing this crap so big gas can sell LP overseas. It is a lose/lose for the U.S. , our water is at risk and we have higher LP prices.
My lock in contract is 17 cents higher then last year, $1.54 with a lock in, $1.69 without. Ouch!
If You use propane it might be wise to lock in Now.
