Constellation Energy fell 11% after the Federal Energy Regulatory Commission blocked a proposal to boost power from the Susquehanna nuclear power plant to Amazon's data center.

The application, submitted by grid operator PJM Interconnection and Talen Energy's Susquehanna power plant, sought to increase power from 300 to 480 megawatts.

This decision affects not only Talen, but also companies like Constellation Energy. Constellation and other energy providers had been looking for similar offerings to meet the increasing power needs of data centers, which are becoming increasingly important for AI and cloud services.

In September, Constellation announced plans to restart the Three Mile Island nuclear power plant under a 20-year power purchase agreement with Microsoft, which will use the electricity to support its data centers. This deal is Constellation's largest power purchase agreement to date.

Nvidia is expected to replace Intel in the Dow Jones Industrial Average on November 8th. Intel shares fell 3% after the announcement, while Nvidia rose 2%.

Paint giant Sherwin-Williams will also join the Dow, taking Dow Inc.'s place, according to a statement.

Nvidia shares have risen 178% this year and its market capitalization has reached $3.3 trillion, putting it alongside Apple and Microsoft.
