In two previous posts, I talked about how easy it is to purchase electricity generated from renewable sources if your state offers consumer choice in electricity. The first post told you how to find out if your state offers consumer choice, and how to get started in choosing your electricity. The second post in this series walked you through the process of switching.
Here I will review the cost compared to what I would pay if I let Pepco choose my electric supply for me, and what would be my power mix if I did not switch.
My electric supplier is WGL Energy—formerly Washington Gas Energy Services. They were an early supplier of green energy options, and I learned about them several years ago at the Washington Green Festival.
My latest contract was renewed at 12.3 cents per kilowatt-hour, increasing a bit from last year’s 11.8 cents per kilowatt-hour. (You can probably do better if you are newly switching, as companies offer enticing prices for new customers.) On my last bill, covering late June/early July (a hot stretch in which our A/C got a workout), I was charged for 744 kilowatt-hours. WGL charged me 11.8 cents x 744 kilowatt-hours = $87.79. At the time, the standard issue service cost 9.14 cents per kilowatt-hour. (Standard issue service cost actually fluctuates slightly between summer and winter months.) My extra cost was $19.79 for the month.
For that, I am getting 100 percent wind-generated electricity, and the carbon emissions from electricity I am buying is zero. The fuel mix for standard offer service, as of the last time it was calculated for Pepco customers, is coal (43.5 percent), followed by nuclear power (34.7 percent) and natural gas (17.5 percent). Only 4 percent is generated from renewable sources. That $19.79 for the month is my environmental premium with WGL. The price of Standard Offer Service goes up and down, as does the price of wind power (though you are protected from price fluctuations for the length of your contract, if you have a fixed-price contract).
