Your gas utility rates include both the cost to deliver service to your home or business and the cost of the natural gas commodity charged by our suppliers. Similar to other energy prices, the commodity cost of natural gas can increase and decrease according to gas market pricing. The Energy Resources Department does not produce natural gas; we buy natural gas on the open competitive market. We will continue to purchase natural gas at the most competitive price. However, as a direct result of these price fluctuations, your gas bill may be higher compared to last year's bill.
