How Does Pure Power® Work?
Residential customers can participate in Pure Power in one of three ways:
100% Pure Power Usage: For the average Ameren Missouri customer, 100% Pure Power usage will add an additional penny charge for each kilowatt-hour (kWh) of electricity used each month. This will add around an additional $10 to your bill each month depending on your electric usage. (If you don’t know your monthly usage, you can view your personal usage history by either logging in or signing up for Ameren Missouri’s online account.) Sign-up information.
Pure Power Blocks: Purchase Pure Power Blocks* for an additional $10.00 per each 1,000 kWh block. One block captures the green power attributes (greenhouse gas reduction) from 1,000 kWh (or 1 megawatt-hour) of regional renewable energy delivered to the Midwest energy pool. Sign-up information.
Pure Power Half Block: Purchase a 500 kWh Pure Power Half Block for $5 a month. This option is designed for customers who want to support renewable energy at a more economical commitment level. Sign-up information.
For My Business:
Business customers who participate in Pure Power indicate how many Blocks* you wish to purchase. Each 1,000 kilowatt-hour (kWh) block costs $10 - which equals one Renewable Energy Certificate (REC) from regional renewable sources that will be added to the Midwest energy pool.
No contract is required to participate in the Pure Power program. For more information, review the FAQs.
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.
