Ameresco, Inc. and Republic Services, Inc. announced on January 6 2026 that a 5.2‑MW renewable natural gas (RNG) plant at the Upper Rock Island County Landfill in East Moline, Illinois, began operation in December 2025. The facility upgrades 2,000 standard cubic feet per minute of landfill gas into pipeline‑quality RNG, producing more than 500,000 dekatherms of energy annually and displacing over 27,000 metric tons of CO₂ each year.
The project marks the 16th joint venture between Ameresco and Republic Services and is a key component of Ameresco’s strategy to expand its renewable fuels portfolio. By converting landfill gas into RNG, the company adds a new revenue stream and strengthens its position in the growing market for low‑carbon transportation fuels and industrial applications. The facility also supports Illinois’ ambitious clean‑energy targets, which aim for 40 % renewable energy by 2030 and 100 % clean energy by 2050.
Ameresco’s recent financial performance underscores the significance of the new plant. In Q3 2025, the company reported revenue of $526 million—exceeding analyst expectations of $518.4 million—and earnings per share of $0.35, a $0.11 beat over the consensus of $0.24. Gross margin improved to 16 %, driven by higher‑margin projects and disciplined cost management. The company reaffirmed its 2025 guidance, targeting 10 % revenue growth, and its backlog of $5.1 billion signals continued demand for clean‑energy solutions.
Management highlighted the partnership’s success and the broader strategic impact. Michael Bakas, President of Renewable Fuels at Ameresco, said, “The conversion of organic waste into renewable energy serves as a cornerstone of the circular economy. The Upper Rock project adds another high‑quality RNG facility to our portfolio and demonstrates the scalable model we've built organically in partnership with Republic Services.” Tim Oudman, Senior Vice President of Sustainability Innovation at Republic Services, added, “This project represents another milestone in our longstanding partnership with Ameresco.”
Analysts have responded positively to the announcement. Several firms have raised their price targets and maintained buy ratings, reflecting confidence in Ameresco’s execution and the growing demand for RNG. The company’s strong earnings beat, robust backlog, and strategic partnership with Republic Services reinforce its competitive position in the renewable‑energy market.
The operational start of the Upper Rock facility demonstrates Ameresco’s ability to deliver turnkey RNG projects at scale. It strengthens the company’s renewable‑fuel pipeline, supports state clean‑energy goals, and reinforces a proven partnership model that is likely to drive future growth.
