U.S. grid operator PJM Interconnection has informed Constellation Energy (CEG) that the Three Mile Island nuclear plant likely cannot connect to the power grid until 2031. This new timeline represents a significant four-year delay from the company's original restart plans, impacting long-term growth projections. The disclosure was made during the CERAWeek energy conference in Houston, highlighting the infrastructure challenges facing the U.S. power sector. PJM cited extensive interconnection queues and existing grid constraints as the primary reasons for the postponed integration. The delay is a notable setback for Constellation Energy’s strategy to capitalize on the surging power demand from AI-driven data centers. Market analysts suggest this development could temper the recent optimism surrounding nuclear energy stocks and the broader utilities sector (XLU).
