• Calculate Annual Consumer Savings

  • Maryland

  • To calculate your potential annual savings as an individual consumer, determine the difference between your calculated “Weighted Average Price of SOS electricity beginning October 1, 2016 through September 30, 2017” 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.

    1. Look at the “Current Price for SOS electricity effective through May 31, 2017” in column (B) and the "Price of SOS electricity beginning June 1, 2017 through September 30, 2017" in column (C) of the chart below to determine your correct rates.

    3. Calculate the Weighted Average Price of SOS electricity beginning October 1, 2016 through September 30, 2017. The following is an example using the above individual consumer in Pepco’s Residential (Schedule "R") rate class. 

      Cost of SOS June 1, 2017   through September 30, 2017 (cents) Cost of SOS October 1, 2016 through May 31, 2017 (cents) Weighted Average Price of SOS electricity Beginning october 1, 2016 through september 30, 2017 (cents per kWh)
    Residential (Schedule "R") (4,168 X 7.98)
    = 33,261
    (4,832 x 8.65)
    =  41,797
    (33,261 + 41,797)
    ÷ 9,000
    = 8.34

    4. The following is an example using the above individual consumer in Pepco’s Residential (Schedule "R") rate class.

    = 1.00 CENTS/KWH
    ×  750 KWH

    Average Monthly Savings
    Months/Year


    =$7.50 
    × 12

    Average Annual Savings

    =$90.00
