Ameren Missouri is preparing for significant growth in electricity demand as large-load customers, particularly data centers, continue to expand across the state.
In its newly released 20-year Integrated Resource Plan, Ameren Missouri outlines a substantial expansion of its generation portfolio to maintain reliability as customer demand grows. The plan includes a mix of natural gas, solar, energy storage, wind, nuclear and other technologies. Ameren
One of the biggest shifts is the scale of planned natural-gas generation. Reporting on the new plan indicates Ameren could add roughly 11,100 megawatts of natural-gas generation over the next two decades, with data-center growth playing a significant role in projected electricity demand.

The demand isn’t theoretical. Major projects announced this year include Google’s $15 billion data-center investment in New Florence and Amazon’s $10 billion data-center campus in Montgomery County. Ameren says the Amazon development alone is expected to support thousands of construction jobs. Ameren
For the St. Louis construction community, the expansion points to potential work extending well beyond the data centers themselves, including:
- New power-generation facilities
- Transmission and distribution infrastructure
- Substations and switching equipment
- Engineering and utility construction
- Supporting civil and site infrastructure
- Skilled-trades and specialty-contractor opportunities
Ameren’s plan also comes amid debate over the future generation mix. The company says the strategy is designed to maintain reliability and manage costs while serving unprecedented load growth; environmental advocates have criticized the increased reliance on natural gas and its implications for fossil-fuel use.
