* The Green Mountain Client Affiliate Program is available to specified customer groups actively affiliated with CAP partner companies to which Green Mountain provides commercial retail electricity service. This offer is not transferable and is only available to residential customers. Customers enrolling in the Power As You Go PlanSM are not eligible.

** The CAP discount will be effective within two billing cycles after registration and verification of affiliate status. The discount will be calculated as a percentage of the recurring Green Mountain energy charges and any passed-through recurring TDSP charges for current month’s usage and will exclude any nonrecurring charges or fees, third-party services, taxes or tax reimbursement charges or guard lights. The discount will be applied to a single meter per customer, before other discounts or billing options are calculated.

To receive the CAP discount, you must be a Green Mountain customer and the electricity account must be in your name. The discount ends if you move to a different service address. Re-enrollment at a new service address is subject to continuing eligibility.

Your participation in the Client Affiliate Program and associated discount will end immediately upon termination of your affiliation with the CAP partner company or upon termination of the CAP partner company’s electricity supply contract with Green Mountain. Green Mountain reserves the right to discontinue this program without notice.
