Callaway County legislator, Ameren respond to solar facility concerns
Ameren Missouri received unanimous approval from the Missouri Public Service Commission for its largest solar facility in Reform, Callaway County, which aims to diversify the grid and meet the growing demand from large users like data centers. While the facility, expected online by 2028, addresses future energy needs for data centers planned by Google and Amazon in New Florence, concerns have been raised by the Office of the Public Counsel regarding cost allocation for large-load users versus residential customers.
Ameren Missouri has secured unanimous approval from the Missouri Public Service Commission (PSC) to construct its largest solar facility to date in Reform, Callaway County. The 250-megawatt facility, slated for completion by 2028, will occupy 1,160 acres adjacent to Ameren's existing nuclear plant and is intended to enhance grid diversity and production capabilities. A key driver for this expansion is the escalating energy demand from large-load users, specifically citing data centers.
The article highlights the recent announcement by Google of a $15 billion campus, including a data center, in New Florence, about 20 miles from the solar project, with Amazon also planning a data center in the same city. These developments underscore the growing need for increased energy generation in Missouri. State Rep. Jim Schulte, a member of the House Utilities Committee, emphasized the critical role of energy production for economic development in the county.
Despite the approval, the Office of the Public Counsel (OPC) raised concerns regarding the financial burden on residential consumers. OPC Chief Economist Geoff Marke argued that large-load consumers like data centers should bear the full cost of infrastructure investments required to serve their demand, warning that current cost-sharing practices could lead to significant rate hikes for existing customers. Ameren and Governor Mike Kehoe's office countered that Senate Bill 4, passed in 2024, includes provisions requiring data centers to pay their representative share of costs, ensuring robust protections for all customers.
Ameren maintains that the new solar facility offers a shared benefit by increasing energy flexibility and reliability across the grid. The ongoing debate over cost allocation and the optimal energy mix – with the Missouri House Utilities Committee showing a preference for nuclear energy due to its reliability – is expected to be further discussed in future rate case hearings before the PSC.
