Propane accounts for the majority of the volume in the Gas Division’s LPG business. While propane is often used for water heating, cooking, motor fuel, and process applications, domestic heating dominates usage in the market. As a result, primary counterparts include major international oil companies, financial institutions, commodity trading firms, and end users. The market for LPG is highly seasonal and demand is higher during the cooler months.
