Castle Bluff Energy Center
The Castle Bluff Energy Center will be a reliable backup source of energy ready to use when customers need it most.
Reliable Energy When Customers Need It
The Castle Bluff Energy Center will be a reliable backup source of energy ready to use when customers need it most. It’s designed to bolster grid reliability and can be used to deliver energy on the hottest summer days, the coldest winter days or when renewable energy is not generating as forecasted. The site previously hosted similar on-demand generation as part of the Meramec Energy Center. Castle Bluff represents a significant upgrade in reliable backup energy for customers. Construction is subject to approval from the Missouri Public Service Commission.
Economic Development
Developing Castle Bluff will employ hundreds of construction workers, create permanent jobs and provide additional tax revenue for St. Louis County and the surrounding region. Whenever possible, Ameren Missouri hires local contractors, labor, and diverse-owned businesses.
Good Neighbors
Ameren Missouri has been a fixture in the community for generations, and we have long-standing, established relationships with our neighbors. Operations at the Castle Bluff Energy Center will be quieter than its predecessor. We anticipate minimal traffic to support operations. Unlike with the Meramec Energy Center, there will be no regular train deliveries or trucks hauling away materials as part of Castle Bluff’s day-to-day operations.
Environmental Stewardship
Projected emissions, even in the case of increased demand due to extreme temperatures, are far below those of its predecessor.

Frequently Asked Questions
It's necessary for grid reliability and delivering energy when our customers need it most, especially on the coldest winter mornings and hottest summer days. Castle Bluff is primarily fueled by natural gas, which is a reliable source of energy because it's available 24/7, 365 days a year. It's flexible, always available, and can provide the energy necessary for our customers when renewables are not available due to weather or time of day.
The site was chosen for several reasons, all of which will help keep construction and operation costs down, which translates to lower rates for customers. Ameren Missouri already owns the property. Most importantly, there is existing infrastructure and transmission line access.
No. Natural gas is naturally odorless. The odor many associate with natural gas is mercaptan, which is added to the gas delivered to your home as a safety precaution. The Castle Bluff Energy Center will not use any mercaptan.
