Google's Power Deal Fuels Fresh Interest in Nuclear Stocks

Read MoreHide Full Article

Key Takeaways

  • TLN, OKLO and SMR rose as Google's 20-year nuclear deal fueled broader investor interest in the sector.
  • TLN posted a double-digit gain as Google's deal signaled demand for firm power in the same PJM market.
  • OKLO rose over 7% and SMR over 4% as the deal improved sentiment toward advanced reactor developers.

Constellation Energy’s (CEG - Free Report) new agreement with Alphabet Inc.’s (GOOGL - Free Report) Google gave nuclear stocks a sharp lift after a difficult stretch for the sector. The deal matters because Google is putting long-term money behind nuclear power to meet rising electricity demand from data centers. Investors quickly carried that signal beyond Constellation Energy, sending Talen Energy (TLN - Free Report) , Oklo Inc. (OKLO - Free Report) and NuScale Power (SMR - Free Report) higher as well.

Constellation Energy shares climbed more than 12% following the announcement, while Talen Energy also posted a double-digit gain as investors looked to other nuclear-exposed power producers. OKLO rose more than 7%, and NuScale Power advanced more than 4%, showing that the enthusiasm spread from established nuclear generators to developers of next-generation reactor technology as well.

What Google is Buying From Constellation

Google and Constellation Energy signed a 20-year power purchase agreement tied to upgrades at 11 existing nuclear units in IL, PA and NJ. Constellation plans to spend more than $4.3 billion on the work, which is expected to add 890 megawatts of nuclear capacity to the PJM grid. The first added output is expected in 2028, with the full amount scheduled before the end of 2032.

The arrangement allows Constellation Energy to add nuclear generation by upgrading reactors already in operation, avoiding the longer timelines associated with building a new plant. Google secures a long-term supply of reliable, around-the-clock electricity, while Constellation gains contracted revenues to support the planned upgrades.

For investors, that provides a real example of a large technology company paying for additional nuclear generation rather than simply discussing future power needs.

Why TLN Joined the Rally

Talen Energy benefited because it sells electricity into the same PJM market as Constellation Energy. PJM covers a large part of the Mid-Atlantic and Midwest, where electricity demand has been rising and available generating capacity is tight. Google’s willingness to secure long-term firm power was therefore read as a favorable pricing signal for other generators in that market.

Talen Energy — carrying a Zacks Rank #3 (Hold) — was not directly involved in the Google-Constellation agreement, but investors viewed the deal as a positive signal for other nuclear generators operating in the same power market. TLN benefits from similar demand for reliable, round-the-clock electricity, helping explain the stock’s strong response to the announcement.

OKLO and SMR Gain on Future Nuclear Demand

The case for OKLO and NuScale Power is different. Unlike Constellation Energy and TLN, these companies are developing new reactor technologies rather than selling large amounts of power from established nuclear fleets.

OKLO is developing its Aurora powerhouse, while NuScale Power is focused on small modular reactors. SMR also holds an important regulatory distinction: NuScale has a small modular reactor design certified by the U.S. Nuclear Regulatory Commission.

The deal did not directly generate business for OKLO or NuScale Power, but it gave investors a clearer sign that large technology companies are willing to commit long-term capital to nuclear energy. This improved the sentiment toward advanced reactor developers by making future commercial demand for their technologies easier to justify.

Still, the Google-Constellation agreement does not alter the execution path for OKLO or SMR. Licensing, construction and first deployment remain the key hurdles, so both companies still need to convert planned reactor projects into operating assets before the demand can translate into meaningful revenues.

What the Deal Means for Nuclear Investors

The strongest message from the Constellation Energy-Google agreement is that data-center growth is creating paying customers for dependable nuclear electricity. Talen Energy benefits from its exposure to the power market where that demand is appearing, while OKLO and NuScale Power gain from expectations that future nuclear projects may find willing large-scale buyers.
