You can use our easy online Savings Calculator or you can compare the price per kilowatt hour (kWh) offered by AEP Energy to the 'Price to Compare' (PTC) on your electricity bill. The PTC is the price you currently pay for electric generation service from the local utility. Take your Price to Compare and subtract our offer price. This equates to your savings per kWh. Multiply your savings per kWh by your monthly usage (kWh) to determine your savings amount per month.
