The Price to Compare (PTC) is the average cost per kilowatt-hour (kWh) for supply, based on your rate classification. The PTC is a tool for you to use in comparing Delmarva’s Standard Offer Service (SOS) electric supply rates with offers from competing certified electric suppliers. To calculate your potential savings as a consumer in a rate class, determine the difference between our "Price to Compare" and the price of other alternate electricity suppliers participating in the Energy Choice Program by subtracting one from the other. If the supplier’s price is less than the "Price to Compare," you’ll save money. Multiply that difference by your average monthly kilowatt-hour (kWh) usage to determine your average monthly and annual savings.
