How is the value of refinery fuel gas determined?
The value of refinery fuel gas is based on the average of the most recent 36 months of the “Henry Hub” natural gas spot prices, as published by the federal Energy Information Administration (EIA). The 36-month average value is calculated and published by the Department of Revenue on a quarterly basis.
