Part of SMR technology is gaining serious attention from major tech companies like Google, Microsoft, and Oracle, while Oklo and Vertiv pursue collaborations amidst market competition from Constellation Energy.

How could the increased capacity at Constellation Energy affect Walmart's power supply?

Likely What happens if… A possibility worth considering, not a forecast.

Walmart may benefit from enhanced power reliability due to Constellation's capacity upgrades The investment by Google into Constellation Energy's operating nuclear reactors is projected to add 890 megawatts to the PJM grid across multiple states. Because Constellation Energy supplies nuclear power to Walmart under a long-term power purchase agreement, this increased capacity and stability in the regional grid should translate into a more reliable and robust power supply for Walmart's operations. This upgrade is considered faster and cheaper than building new power generation capacity.

The facts so far

As reported. Each one links to where it comes from.

  • Google invested $4.3 billion to expand generation capacity at 11 of Illinois’ nuclear generator sites with Constellation.cities929.com
  • The Google-backed project is projected to add 890 megawatts to the PJM grid across multiple states in the region.cities929.com
  • Prices in PJM’s capacity market have increased over a thousand percent from 2023.cities929.com

Why it matters

The stability of the PJM Interconnection is critical for large consumers like Walmart, which relies on consistent, high-volume power for its extensive operations. Projections warned of reliability problems in the near future due to the increasing load from data centers, which has driven capacity market prices up dramatically.

This investment helps address those grid reliability concerns by adding firm, nuclear-based capacity. It is part of a broader effort by governors across the PJM region to create a collaborative organization aimed at lowering energy costs and ensuring a better system for all constituents.

What we don't know yet

  • Will the increased capacity lead to a measurable reduction in energy costs for Walmart?
  • How quickly will the 890 megawatts of new capacity be fully integrated into the PJM grid?

What would change this answer

The PJM Governors’ Collaborative successfully implements coordinated planning efforts.The overall stability of the grid could improve faster than expected, potentially mitigating the need for emergency capacity measures.
New data center developments are slowed or halted in the PJM region.The pressure on the grid capacity market would ease, reducing the urgency for new generation capacity.
