Constellation agreed to buy a minority equity interest in five operating Pine Creek RNG production facilities in Washington, Utah, Iowa, and Illinois in May 2026. The assets produce about 1.5 million MMBtus of RNG per year, with a framework to develop another 3.0 million MMBtus annually. Constellation is a listed buyer with a 55 GW generation fleet. Pine Creek RNG is a private developer and operator.

The shift in US RNG M&A is clear: buyers are not just acquiring production exposure. They are securing operating supply, environmental attributes, and customer delivery channels. For Constellation, the commercial value is the ability to match RNG supply with demand from customers seeking gas decarbonization without changing reliability requirements.

The deal fits the broader 2025 clean-energy M&A pattern tracked by Enerdatics, where buyers have favored de-risked, operating, or near-operating assets over earlier-stage pipelines amid tighter financing and policy scrutiny.

Unlike early-stage RNG development, these facilities are already producing pipeline-quality gas. That reduces execution risk and gives Constellation immediate marketing optionality across RNG volumes and related environmental attributes.

Pine Creek also retains a growth path through the additional 3.0 million MMBtus/year development framework. That makes the agreement both an operating-asset acquisition and a platform-expansion partnership.

The next signal for US RNG M&A is more minority-stake and offtake-linked equity deals, especially where listed utilities and IPPs can control customer access, attribute monetization, and future RNG supply growth.
