Why was the VC Summer nuclear project originally abandoned?

The VC Summer Units 2 and 3 were abandoned in 2017 due to cost overruns, delays, and the bankruptcy of the main contractor, Westinghouse, after $9 billion had been spent and the reactors were less than 50% complete.

What makes VC Summer reactors viable for revival now?

With most physical infrastructure already in place and growing demand for clean baseload energy, the reactors can potentially be completed faster and more cost-effectively than new builds, making them attractive to investors and utilities.

Who is evaluating the project now?

Santee Cooper, South Carolina’s public utility, has shortlisted several global companies from its RFI process. These parties are now conducting due diligence before submitting final proposals by the end of 2025.

What are the broader market trends supporting nuclear energy in the U.S.?

Nuclear power is experiencing a resurgence driven by data center energy demand, decarbonization policies, and the need for reliable baseload electricity. This is leading to the reactivation of plants like Palisades and proposed projects like VC Summer's revival.

VC Summer Nuclear Reactors

Momentum Builds to Revive VC Summer Nuclear Reactors in South Carolina

In a significant development for the future of American nuclear energy, the long-dormant VC Summer Units 2 and 3 in South Carolina are once again in the spotlight. These partially completed nuclear reactors, abandoned in 2017 after substantial financial and technical setbacks, are now being reevaluated as potential keystones in the U.S.'s clean energy transition.

From Dormancy to Opportunity

Once seen as symbols of nuclear overreach, the VC Summer reactors are gaining renewed attention thanks to favorable shifts in both market demand and energy policy. With more than $9 billion already invested and substantial physical infrastructure in place, the site presents a rare opportunity: a near mid-construction nuclear project that could be revived at a fraction of the time and cost required for a ground-up build.

Strategically located adjacent to Dominion Energy's operational Summer Unit 1, the VC Summer site holds grid advantages, including transmission access and water resources—both essential for gigawatt-scale power generation.

Global Interest from Tech and Energy Giants

Santee Cooper, South Carolina’s state-owned utility and the original project sponsor, has taken structured steps to identify a capable partner. Out of 14 global RFI respondents, fewer than five have been shortlisted. A Santee Cooper spokesperson confirmed that final proposals are expected by the end of 2025, with due diligence currently underway.

“Santee Cooper does not intend to own or operate the units but seeks to enable a capable entity to pursue completion for the broader benefit of South Carolina,” the spokesperson added.

Clean Energy Needs Driving a Nuclear Comeback

The revival of VC Summer aligns with a broader nuclear resurgence. With hyperscale data centers and AI-related computing driving energy demand, nuclear power's reliable, carbon-free generation is more valuable than ever.

Holtec’s planned restart of the Palisades Plant and Constellation’s proposed reactivation of Three Mile Island Unit 1 further demonstrate the industry’s forward momentum. In this new context, VC Summer is no longer seen as a stranded asset—but a strategic opportunity.

Conclusion: A Second Chance at a Clean Energy Future

While the original VC Summer project was marked by delays and cost overruns, today’s energy environment paints a different picture. If revived, these reactors could support South Carolina’s energy security, reduce emissions, and contribute significantly to America’s clean energy future.
