Supply Price Comparison – Individual Consumer
To calculate your potential annual savings as an individual consumer, determine the difference between your calculated “Weighted Average Price of SOS electricitybeginning June 1, 2013 through May 31, 2014” 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.
