Ameren Missouri Renewable Energy Rate Options 
Your Ameren Missouri electricity rate includes basic service and can now include a choice of two renewable energy options. All customers have basic service (electricity from mainly traditional generation sources) and will continue with that service even if they elect to add a renewable option.

Renewable Energy Options:
Through the Pure Power™ program, Ameren Missouri offers two renewable energy options to residential customers (see chart) that support the development of new renewable energy sources through the purchase of renewable energy credits (RECs.) RECs can be purchased from local renewable energy sources like wind, geothermal, solar or landfill gas in an amount equal to all or some of the energy you use each month. Each option has different features, but both provide customers with an easy way to support the continued development of renewable energy - right here in Missouri.

The Pure Power program is certified by Green-e Energy, which requires companies to provide their customers with this notice. Information about our Green-e energy certification is available online or write or phone Green e-Energy:

Choosing a renewable energy option helps offset your carbon footprint and creates environmental and economic benefits for the region. Your choice supports renewable energy beyond what Ameren Missouri already generates or purchases for all our customers. Participation is voluntary, and can be cancelled at any time.
