Constellation Energy announced Thursday that it will acquire the Rhode Island State Energy Center from Shell Energy North America for $715 million, marking a major change in ownership of the 609-megawatt natural-gas combined-cycle plant that sells power into the ISO New England wholesale market.
Deal terms and timing
The transaction values the plant at $715 million, which the companies say is about $580 million net after expected first-year tax benefits. Constellation expects the purchase to close in the first quarter of 2027, subject to customary regulatory approvals and other closing conditions.
Until the deal is finalized, the plant — held by RISEC Holdings, LLC — will continue to operate under Shell's ownership, the companies said.
"The Rhode Island State Energy Center is a high-performing asset that perfectly complements Constellation's extraordinarily successful customer business in New England," said Joe Dominguez, chairman, president and CEO of Constellation.
What the plant does and who it serves
The Rhode Island State Energy Center is a natural gas–fired combined-cycle facility with 609 megawatts of capacity. It participates in the ISO New England market, providing both energy and capacity to the regional grid. Combined-cycle plants of this type generally run with higher efficiency than older simple-cycle gas plants, allowing operators to produce more electricity per unit of fuel.
Financial and strategic impact for Constellation
Constellation said the acquisition is expected to be immediately accretive to operating earnings and to deliver returns above the company’s stated 10% unlevered return threshold. Company guidance indicates the purchase will not affect its ability to complete $5 billion in authorized share repurchases by the end of 2027.
Market reaction was muted in early trading: Constellation Energy Corp. (CEG) stock was up roughly 0.10% while Shell Plc (SHEL) gained about 0.36% in overnight activity following the announcement.
Local and regional considerations
For Rhode Island and the wider New England region, the sale transfers a sizable dispatchable generation resource into Constellation’s merchant portfolio. Dispatchable plants are a key part of grid reliability, particularly during periods of high demand or when intermittent resources such as wind and solar produce less output.
Because the plant sells into the ISO New England market, any change in ownership does not immediately alter market access or how the plant is dispatched, but it does shift long-term operational and investment decisions to a new corporate owner with its own portfolio strategy.

Next steps and regulatory review
The companies noted that the transaction will proceed following routine regulatory reviews and satisfaction of closing conditions. Those reviews can include state and federal antitrust assessments and market-impact analyses by regional grid authorities. Representatives for Constellation and Shell did not detail a timeline for specific regulatory filings.
Local stakeholders, including state energy officials and ISO New England, typically monitor such transfers for any implications on regional reliability, market competitiveness and, in some cases, workforce continuity at the facility. Constellation’s statement indicates the acquisition will become part of its merchant generation fleet as the company expands its New England presence.
As the deal progresses through approvals, plant operations and market scheduling will continue under current ownership, according to the companies.
Reporting from this newsroom will follow further filings and statements from Constellation, Shell and regional officials that could clarify any operational changes, workforce plans or local impacts tied to the transfer of ownership.
