May 15, 2026 [Storage Terminals Magazine]- Constellation and Pine Creek RNG have announced a long-term agreement aimed at expanding renewable natural gas (RNG) production capacity across the United States.

As part of the agreement, Constellation will acquire a minority equity interest in five operational Pine Creek RNG facilities located in Washington, Utah, Iowa, and Illinois. The existing portfolio currently produces approximately 1.5 million MMBtus of RNG annually.

The collaboration also establishes a framework for the joint development of additional RNG projects capable of generating approximately 3.0 million MMBtus per year, further supporting growing demand for sustainable energy solutions.

The partnership reflects Constellation’s continued focus on advancing decarbonisation initiatives and expanding access to lower-carbon energy products for customers. Through the agreement, Constellation will also market the RNG production and associated environmental attributes, strengthening its ability to align renewable gas supply with customer demand.

Pine Creek RNG noted that the partnership represents a significant milestone for the company as it continues to scale its renewable energy operations and accelerate project development.

Renewable natural gas is produced from the decomposition of organic materials, including landfill waste, wastewater treatment processes, and agricultural or industrial digesters. After purification, RNG can be injected into interstate pipeline networks and used similarly to conventional natural gas, including for power generation and transportation fuel applications.
