FGU's natural gas acquisition strategy, predicated on continuous analysis of factors such as long-term market opportunities, supply and receipt point availability, past pricing behavior, and pricing forecasts, has historically resulted in competitively priced gas for its members. In an attempt to secure the most economically priced reliable gas deliveries possible, FGU utilizes a combination of long-term, monthly, and daily swing purchases through agreements with approximately 50 natural gas suppliers.

In addition to the cost of member-specific purchases of baseload gas, members are allocated their proportionate share of FGU's aggregated monthly purchases. These aggregated purchases, which typically blend some amount of monthly and daily acquisitions, comprise the FGU "system supply".
