How is the SCO rate determined?
Standard Choice Offer (SCO) rates are set based on a simple formula:
- Current market rate for natural gas as determined by the monthly closing price for the natural gas contract on the New York Mercantile Exchange (NYMEX).
- Plus a fixed retail price adjustment reflecting the additional cost to bring the gas to the customer. The retail price adjustment was determined in a competitive auction administered by Columbia Gas of Ohio and approved by the Ohio Public Service Commission.
Since current market rates change based on supply and demand, the monthly rate charged to customers will change as well.
