The Price to Compare (“PTC”) is the average cost per kilowatt-hour (kWh) for generation and transmission service, based on your rate classification. The PTC is a tool for you to use in comparing Pepco’s Standard Offer Service (SOS) generation and transmission rates with offers from competing certified or licensed electricity suppliers.
The Price to Compare is calculated by taking the total kilowatt-hour usage for all customers within a specific rate class for a 12-month period and multiplying that amount by the actual generation and transmission rates. This total amount is then divided by the total 12-month kilowatt-hour usage which provides an average per kilowatt-hour rate for generation and transmission for the rate class, which is the Price to Compare.
To calculate your individual Price to Compare (rather than using the average Price to Compare for your rate class), you should total your summer and winter kWh and multiply each total by the generation and transmission rates shown on your rate schedule. This
calculation will result in your summer and winter revenue totals,
respectively. You should then add the
summer and winter revenue totals, then divide by your total kWh. The result is
your individual Price to Compare.
