Data Centers Deliver Savings for Other Customers

Data center growth is expected to deliver $21 million in projected customer savings while supporting economic development under a framework that includes strong customer protections.

As Missouri continues to attract companies looking to invest and create jobs across the state, including data centers, questions have been raised about what that growth means for existing customers.

Ameren Missouri customers are expected to see $21 million in projected base rate savings over the next two years, driven by committed data center customers. Customer protections established through the company's Powering Missouri Growth Plan, in alignment with Missouri Senate Bill 4, ensure data centers do not receive discounted electric rates and must pay upfront 100% of all costs associated with hooking up to the energy grid.

Another key benefit is that new large load customers are expected to help lower costs by spreading fixed electric system expenses across a broader customer base. Data center development can also bring substantial economic investment to local communities through construction activity, permanent jobs and increased tax revenue supporting public services. Communities that welcome data centers can benefit from job creation, infrastructure investment and additional funding for schools, roads, bridges and first responders.

"New data centers receive no discounts on their electric rates and are already beginning to pay for infrastructure that benefits all customers, making everyone's rates lower than they otherwise would be," said Rob Dixon, vice president of regulatory, legislative and external affairs for Ameren Missouri. "For example, commitments from new data center customers are expected to deliver about $11 million a year in base rate savings for other customers, showing how growth can make everyone's rates lower than they otherwise would be."

Ameren Missouri has a long history of planning for growth and investing in the electric system to provide reliable service for the 1.3 million customers who depend on electricity every day. As Missouri competes for new business investment and energy needs continue to evolve, the company remains focused on supporting economic growth while maintaining reliable service for customers.
