The SCO price reflects the monthly settlement price* for natural gas plus a retail price adjustment of $0.130 per one hundred cubic feet (CCF). For example: If the July month-end settlement price for natural gas is $0.43 - when you include the adder of $0.116, the total SCO supplier rate for August is then $0.56 per CCF. The retail price adjustment (the adder) was determined in a competitive auction. The monthly natural gas settlement price will vary month-to-month with changes in supply and demand and other market conditions. As such, the SCO price is a variable price and will change each month as the gas market fluctuates. The three SCO suppliers are: AEP Energy, Direct Energy Services, Spire Energy. Regardless of the name of the supplier listed with the SCO line item, all suppliers’ monthly SCO prices are the same. Therefore, if a friend or neighbor is being served by an SCO supplier but a different supplier is listed, you both are still paying the same monthly SCO price for your natural gas
