Nuclear Power and Data Center Demand: How Ameren, PSEG, and FirstEnergy Are Positioned

Three U.S. utilities are getting renewed attention as nuclear power and data center demand reshape the electricity market. Ameren, Public Service Enterprise Group, and FirstEnergy each bring a different mix of nuclear generation, regulated transmission, and large load growth. Ameren has signed agreements for 2.8 GW of electric service and is working through 4 GW of interconnection studies in Missouri. PSEG is pursuing bilateral deals through PJM's Reliability Backstop Procurement to turn data center inquiries into contracted revenue. FirstEnergy sees roughly 25 GW of data center load by Q2 2026, with 6.4 GW already contracted. These stories matter beyond stock picking. Nuclear plants supply carbon-free baseload power, and the transmission investment needed to serve data centers can support grid upgrades that help broader decarbonization. The article highlights the key risk: whether utility earnings can keep pace with capital plans and regulatory decisions. For anyone tracking clean energy finance, these utilities show how climate goals and AI-driven electricity demand are converging.

Good breakdown of why utilities with nuclear fleets are getting attention. The data center load numbers are the real driver here. Ameren's 2.8 GW of signed agreements plus 4 GW in interconnection studies is a lot of future demand. Worth watching if those projects actually get built and how rates are recovered.

The 4 GW of completed interconnection studies for Ameren is interesting, but studies are not construction. I'd want to see actual in-service dates and whether the grid can deliver that load without major upgrades. Same for FirstEnergy's 25 GW forecast. That seems optimistic unless PJM transmission planning moves fast.

PSEG going through PJM's Reliability Backstop is the part that matters for policy folks. That process determines who gets paid for what and how much risk lands on ratepayers. If the load growth is real, the mechanism needs to reward long-term contracts without letting utilities overbuild on the back of speculative demand.

Nuclear is carbon-free but not emission-free when you count the full fuel cycle. Still, keeping existing reactors online avoids a lot of emissions compared to gas peakers. The question is whether uprates and refurbishments are cheaper than alternatives. The article does not dig into that cost comparison.

If data centers are driving this much load, does that push out renewables on the interconnection queue? Nuclear and gas may get priority because they are dispatchable. Would be useful to see how these utility plans treat solar and wind additions, especially in Missouri and PJM.

Good reminder that nuclear is becoming a front-page story again. But this article is still a stock screen, not an energy analysis. The useful takeaway is that data center demand is large enough to change utility capex plans. For carbon markets, that means more pressure on clean firm capacity.
