Part of Constellation is expanding its ISO New England portfolio and growing its presence in the PJM market through acquisitions, including a gas portfolio.

How could Constellation's new power purchase agreements affect PJM Interconnection?

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

New nuclear capacity and supply deals may ease PJM's critical generation shortages The agreements between Constellation Energy and technology giants Google and Amazon provide significant new capacity and supply commitments to the PJM Interconnection. Specifically, the Google deal funds uprates at six nuclear sites across Pennsylvania, New Jersey, and Illinois, adding 890 megawatts of new capacity, with the first uprate expected in 2028. Additionally, Google signed a 15-year supply agreement for 2,700 megawatts. These additions directly address PJM's reported struggle to find enough power generation to meet anticipated demand, particularly from rising AI data center needs, and introduce operational load-shaping capabilities to manage grid stress.

How it reaches PJM Interconnection

Reported by news outlets

Constellation Energy secured 20-year and 15-year power purchase agreements with Google and Amazon. These deals are backed by a $4.3 billion investment by Constellation and fund upgrades at six nuclear sites in Pennsylvania, New Jersey, and Illinois, adding 890 MW of new capacity. The Amazon deal also includes a 190-MW expansion at the Calvert Cliffs nuclear plant in Maryland, expected between 2030 and 2032.

The new capacity and supply agreements, including the 2,700 MW supply agreement with Google, are brought onto the PJM grid. These upgrades, which take effect between 2028 and 2032, help sustain existing jobs and create construction jobs. Furthermore, the Google deal will incorporate operational load-shaping and demand-response capabilities to reduce power consumption during grid stress.

Why it matters

PJM Interconnection, as the regional transmission organization, is responsible for coordinating electricity flow to 67 million people across 13 states. The reports indicate that PJM has been struggling to find enough power generation to meet anticipated demand, particularly as the energy needs of AI data centers increase. This shortage has been significant enough that PJM has delayed a planned reliability backstop procurement auction.

The influx of reliable, firm power from nuclear uprates and large supply agreements is critical for PJM's operational stability. By bringing new capacity online and integrating advanced technologies like load-shaping, the deals help mitigate the immediate risk of supply gaps and support the continued growth of digital infrastructure in the region.

What we don't know yet

Will the new capacity be sufficient to close the 6.8 GW capacity gap PJM is facing?
How will the integration of operational load-shaping capabilities change PJM's grid management protocols?

What would change this answer

PJM announces a change in its reliability backstop procurement auction scheduleThis would signal whether the new capacity is deemed sufficient to alleviate the immediate generation crisis.

Constellation secures similar large-scale PPAs in other PJM statesThis would suggest the market is responding positively to private investment, potentially accelerating the filling of capacity gaps.
