Constellation Energy to Acquire 609 MW Rhode Island Gas Plant from Shell for $715M

Constellation Energy (Nasdaq: CEG) announced on September 10, 2026 that it has entered into a definitive agreement to acquire 100 % of RISEC Holdings, LLC—the owner of the Rhode Island State Energy Center—from Shell Energy North America for a total consideration of $715 million, subject to customary purchase price adjustments.

The Rhode Island State Energy Center, located in Johnston, is a combined‑cycle natural gas facility comprising two combustion turbines and one steam turbine capable of producing up to 609 megawatts. The plant operates within the ISO New England wholesale market and is expected to join Constellation’s merchant generation portfolio, further strengthening its ISO New England footprint with flexible, dispatchable capacity.

Constellation described the acquisition as immediately accretive to operating earnings and anticipates returns that exceed the company’s 10 % unlevered return threshold. The $715 million purchase price equates to approximately $580 million net of expected first‑year tax benefits. Crucially, this deal will not impact Constellation’s ability to execute its $5 billion share repurchase program by the end of 2027. The transaction remains conditional on regulatory approvals and other closing conditions.

Strategic Implications

This acquisition enhances Constellation’s dispatchable power capabilities in one of the nation’s tightest power markets. The plant’s combined‑cycle efficiency adds both grid reliability and operational flexibility—traits increasingly valuable in a region experiencing electrification-driven demand growth amid environmental and permitting constraints on new thermal development.

From Shell’s perspective, the sale aligns with its active portfolio strategy. Having acquired RISEC in early 2025, Shell is now realizing value from the asset while simultaneously expanding its footprint elsewhere through the acquisition of a 169 MW natural gas facility in Pennsylvania, reinforcing its PJM market presence.

Impact on CEG

For Constellation, the deal reinforces its position as a diversified and flexible energy provider, particularly relevant in the wake of its earlier Calpine acquisition and ongoing integration. Adding RISEC’s output to its portfolio supports grid stability and complements its substantial clean and nuclear generation platform.

Financially, because the acquisition is immediately accretive and does not derail capital return programs, it signals disciplined strategic expansion. Investors will likely assess the closing timeline and regulatory signals as indicators of Constellation’s continued growth trajectory in merchant generation.

Upcoming milestones to monitor include regulatory approval progress and integration plans. If completed as expected, the acquisition could further solidify Constellation’s role in New England energy markets while delivering tangible value for shareholders.
