Group 1 - The proposed rule by U.S. Energy Secretary Chris Wright aims to expedite the approval process for data center grid access to 60 days, a significant reduction from the current multi-year timeline [1] - Independent power producers are increasingly selling electricity to data centers, leading to stock price increases for companies such as Talen Energy (up 6.25%), Constellation Energy (up 6.4%), Vistra Energy (up 5.3%), and NRG Energy (up 4%) [1] - Nuclear power companies are also benefiting from the AI boom, with stock price increases for Oklo (up 9.1%), Centrus Energy (up 7.8%), Nuscale Power (up 0.45%), and NANO Nuclear Energy (up 4.35%) [1] Group 2 - Data centers can receive expedited approval if they include new power plants and agree to reduce electricity usage during peak demand periods [1] - If data centers are located near existing power plants, studies must be conducted to confirm the necessity of that power capacity for grid reliability [2] - Wright's plan aligns with President Trump's goals of revitalizing domestic manufacturing and promoting AI innovation, both of which require unprecedented electricity supply and significant investment in the U.S. power grid [2]
