• Calculate Annual Consumer Savings

  • To calculate your potential annual savings as an individual consumer, determine the difference between your calculated "Weighted Average Price of SOS electricity beginning June 1, 2014 through May 31, 2015 and the price of other Electric Generation Suppliers participating in the Energy Choice Program by subtracting one from the other. If the supplier’s price is less than the calculated price you’ll save money. Multiply that difference by your average monthly kilowatt-hour (kWh) usage to determine your average monthly and annual savings.
