Quick Overview
- Constellation Energy shares surged 9% during Tuesday’s pre-market session following the announcement of a long-term nuclear energy contract with Google.
- Google’s parent company Alphabet committed to purchasing 890 megawatts of nuclear capacity from 11 Constellation facilities located in three states.
- Both organizations will collaborate on integrating Google Cloud and Gemini technology to optimize power grid management.
- Prior to Tuesday’s gains, Constellation shares had fallen 24% year-to-date.
- The Google partnership represents Constellation’s fourth nuclear supply agreement with a major technology company, adding to existing contracts with Microsoft, Meta, and Amazon.
Shares of Constellation Energy (CEG) advanced 9% to $292.25 during pre-market hours Tuesday. The rally followed news that Alphabet (GOOGL) had secured a 20-year deal to purchase nuclear electricity from the energy provider.

Meanwhile, Alphabet’s shares showed minimal movement, edging up less than 1%. Google’s stock had gained approximately 11% year-to-date heading into Tuesday’s session.
Under the agreement, Alphabet will receive 890 megawatts of nuclear-generated electricity. This capacity will be sourced from 11 Constellation-operated nuclear facilities distributed throughout Illinois, Pennsylvania, and New Jersey.
Google requires this substantial electricity supply to power its expanding network of artificial intelligence data centers. Technology giants have been aggressively securing energy sources as their computational requirements continue to escalate.
Constellation’s Growing Tech Industry Portfolio
The Google partnership isn’t Constellation’s initial venture into serving major technology companies. In 2024, the energy firm reached an agreement with Microsoft (MSFT) to bring Pennsylvania’s Three Mile Island nuclear facility back online.
That partnership was followed by a 20-year commitment to supply electricity to Meta Platforms (META) in 2025. Most recently, just days ago, Constellation announced it would provide Amazon (AMZN) with nuclear power generated at a Maryland installation.
With the Google arrangement, Constellation now counts four significant technology sector partnerships established within a two-year span. The company has effectively positioned itself as the preferred nuclear energy provider for the artificial intelligence expansion.
Additional generating capacity resulting from this agreement will feed into the PJM Interconnection network. PJM operates as the nation’s most extensive grid system, serving 13 states fully or partially, along with the District of Columbia.
Technology Integration Into Energy Management
This partnership extends beyond a simple electricity purchase arrangement. Constellation announced plans to implement Google Cloud and Gemini Enterprise platforms to develop what both companies are calling an “AI for Energy” framework.
The objective centers on leveraging artificial intelligence to reduce infrastructure expenses and enhance grid efficiency. According to both organizations, the technology should also facilitate sufficient power generation to match increasing consumption demands.
There’s an interesting circularity here: artificial intelligence requires substantial electricity, and now utility providers are adopting AI tools to manage power delivery. Whether this approach delivers measurable results remains to be demonstrated.
Notwithstanding these multiple technology sector agreements, Constellation’s stock performance has been disappointing. Through Monday’s trading close, shares had declined 24% for the year, before Tuesday’s pre-market bounce.
Market participants have expressed frustration over the sluggish pace at which profit expansion has materialized following these high-profile announcements. Securing partnerships generates headlines. Converting them into financial results presents a different challenge.
Tuesday’s price jump indicates investors continue responding positively to each new partnership announcement, despite the challenging year-to-date performance. The stock trades considerably below its 2026 opening levels.
Neither Constellation nor Alphabet disclosed the financial terms of the 20-year contract. Both corporations characterized the collaboration as a strategic investment in nuclear energy infrastructure to support artificial intelligence expansion.
