Shell Sells 609-MW Rhode Island Gas Plant to Constellation, Buys Smaller Pennsylvania Asset
Constellation adds dispatchable New England capacity as Shell reshapes its merchant power portfolio ten days after completing its $16.5 billion ARC Resources acquisition.
Shell PLC agreed on Friday (2026-09-11) to sell a 609-megawatt combined-cycle natural gas power plant in Rhode Island to Constellation Energy while simultaneously buying a 169-MW gas-fired plant in Pennsylvania, cutting its net U.S. power capacity by 440 MW. The paired deal reduces Shell's New England exposure and leaves the company with a smaller footprint in PJM, the mid-Atlantic and Midwest grid region.5
Shell completed its $16.5 billion acquisition of ARC Resources, the Canadian Montney shale producer, on Friday (2026-09-04), just ten days before announcing the power swaps. ARC added roughly 370,000 barrels of oil equivalent per day of upstream production. But closing the deal had required Shell to defer the launch of a $3 billion quarterly share buyback, trim a separate planned repurchase from $3.5 billion to $3 billion to preserve cash during supply disruptions linked to the U.S. and Israeli conflict with Iran, and keep a disposal programme running to support those obligations.4,1
"These transactions reflect our dynamic approach to managing our trading portfolio," a Shell president said, without disclosing financial terms for either deal.5
The Rhode Island divestiture fits that disposal pattern. Shell sold a 35% stake in Cyprus Offshore Block 12 to Hungary's MOL for $720 million this year, directing capital toward LNG. Separately, Exxon Mobil is reportedly in the running to acquire Shell's U.S. chemicals business at an estimated $8 billion, according to the Financial Times, citing unnamed sources. Shell's second-quarter adjusted earnings reached $9.84 billion, partly driven by chemicals. But the company's direction has been pointing toward upstream gas and LNG rather than merchant power generation.3,5
Shell's decision to retain the 169-MW Pennsylvania asset while shedding the larger Rhode Island plant suggests the exits are calibrated. PJM's capacity market has been tightening, and a smaller position there gives Shell trading optionality without the operational complexity of running a 609-MW combined-cycle unit in New England.5
Constellation's acquisition logic runs the other way. Chief executive Joseph Dominguez has argued publicly that existing gas-fired plants will play a major role in powering data centers, even as the Ratepayer Protection Pledge pushes hyperscale developers to procure their own new-build generation. Dominguez said earlier this year that demand from data centers and economic growth cannot be met fast enough through new construction alone, making existing capacity the practical near-term answer. A 609-MW Rhode Island combined-cycle unit fits that argument directly.2,5
Gas prices complicate the economics. NYMEX Henry Hub front-month stood at $2.92/MMBtu on Tuesday (2026-09-15), low enough to compress energy margin for combined-cycle generators and shift earnings weight toward capacity market revenues. For Constellation, buying a large gas plant in that price environment amounts to a bet on power demand driven by data centers and broader electrification outpacing new generation supply over the next several years.5
Neither the sale price for the Rhode Island plant nor the acquisition cost of the Pennsylvania unit has been disclosed. With gas-fired capacity changing hands across the U.S. grid at a pace driven partly by technology-sector load growth, the undisclosed Rhode Island valuation is the number competing developers and capacity investors will be looking for when it eventually surfaces.5
