By about how much will monthly prices rise?

Charleston Light and Gas has announced plans to raise its rates in time for the winter season. The plan, pending regulatory approval, would raise gas prices by approximately seven dollars a month for most residential customers. Charleston officials said the rate hike is necessary to keep up with the increasing prices of oil and natural gas. The State Resources Board, the public agency responsible for regulating utilities, plans to discuss Charleston’s request early next week. Should the board approve the rate hike, it would go into effect on the first of December.
