Pure Power

As part of our 2019 rate review, the Missouri Public Service Commission approved the transition of the Pure Power program to a future subscription based program, where participants will receive the existing benefits of the Pure Power program and in addition know the renewable energy associated with the new program is supplied to the Ameren Missouri grid to power your home or business. The Pure Power program will not change until the new subscription renewable program is developed and filed and approved by the Missouri Public Service Commission. We are not accepting new customers in the Pure Power program however you can sign up for the Community Solar program to get on the waitlist for the new renewable subscriber program. Here is a link to the Community Solar program.

Pure Power funds are used to purchase Green-e Energy Certified® RECs from regional wind energy and other renewable generation facilities. More about certification.

No contract is required to participate in the Pure Power program.  

Pure Power customers may cancel their participation in the program at any time by contacting the Ameren Missouri Customer Service Center at 800.552.7583, or by emailing us.

Participation in this program does not constitute the purchase of energy. Renewable Energy Certificates, which represent the environmental attributes associated with past renewable energy generation, are retired on behalf of program participants. All RECs purchased under this program are Green-e Energy Certified® by the independent Center for Resource Solutions.

*1 Block = 1 Renewable Energy Certificate = 1,000 kilowatt-hours
