GreenTherm is a voluntary program that provides Wyoming customers an opportunity to use renewable natural gas (RNG) as natural gas consumers. Customers can elect to have a number of blocks, at $5 each, added as a surcharge to their monthly gas bill. Dominion Energy then uses these funds to purchase “green attributes” associated with the production of renewable natural gas.

Account Information


$5 monthly surcharge per block

* One block is equal to five therms equivalent of RNG. Five therms is equal to half a standard dekatherm. The typical Wyoming residential customer consumes 80 dekatherms of natural gas annually; an annual subscription of one GreenTherm block is equivalent to 6 dekatherms or 7.5% of a typical residential customer’s annual usage

The Dominion Energy GreenTherm Program is an approved program by the Wyoming Public Service Commission. Please note that by submitting this form you agree to let Dominion Energy include at least $5 per block/month surcharge on your bill depending on the number of blocks selected. Submitting this form does not constitute a long-term contract associated with your participation. Please note that customers may apply for or leave this program at any time throughout the year. Changes to a customer’s bill will take effect 30 days after election and will appear on the next bill thereafter. Customers who have, in the most recent twelve-month period (a) received a shut-off notice, (b) entered into a payment agreement with the Company for a delinquent bill, or (c) have had service terminated are not eligible to participate in this program. The GreenTherm offering (price per block, and RNG equivalent per block) may be changed at any time contingent upon approval from the Wyoming Public Service Commission. Please note that this surcharge is completely optional and that you may opt out of it at any time by contacting us at 800-323-5517 or logging in to your account on DominionEnergy.com.
