Argo Infrastructure Partners Expands Solar Footprint with NuGen Deal

The portfolio acquisition underscores Argo’s focus on long-duration, lower-risk infrastructure assets. By integrating these six Massachusetts sites and two New Jersey locations, the firm solidifies its position as a major owner of operational mid-market solar energy in the United States. Michael Madia, Managing Director at Argo, noted that the deal serves as a foundational step in scaling the company’s distributed generation platform.

NuGen CEO David Milner expressed confidence in the arrangement, citing Argo’s track record in essential infrastructure as a key driver for the collaboration. Since its inception in 2013, the investment manager has deployed billions into utilities, renewable energy, and digital infrastructure. This latest purchase marks the firm’s 21st investment, following a significant $470 million agreement earlier in April 2026 to acquire an electric transmission and distribution business from UGI Corporation. Argo currently manages approximately $7.5 billion in assets.
