There was another bit in that link I wanted to add:

Note: Gas for domestic use (cooking and heating) is supplied according to Palestinian demand and is not subject to any limitation by Israel. After the fuel depot at Nahal Oz was repeatedly attacked by Palestinian terrorists from the Gaza Strip, it was forced to limit its operations. The Kerem Shalom crossing has since been adapted to the transfer of fuel. In addition, a new gas line with double the capacity to transfer gas was built.

Biting the hand that feeds you, quite literally.
