Argo Infrastructure Partners LP (investment manager) has acquired a commercial and industrial solar portfolio from NuGen Capital Management, LLC (renewable energy infrastructure firm), bringing Argo's total operating capacity in the C&I solar segment to approximately 270 megawatts across 196 sites, the companies announced.

Deal Details and Portfolio Scope

The acquired portfolio consists of eight operational solar sites, six of which are located in Massachusetts and two in New Jersey. Financial terms of the transaction were not disclosed.

The deal also establishes an ongoing operational partnership between Argo and NuGen, with the Providence, Rhode Island-based developer remaining involved in supporting the long-term performance of the assets within Argo's growing C&I solar platform.

Argo, headquartered in New York, described the portfolio as an established, operational set of assets consistent with its stated strategy of investing in long-duration, lower-risk, higher-quality infrastructure. The transaction is the firm's 21st investment overall.

Scale and Strategic Positioning

With the addition of the eight NuGen sites, Argo's C&I solar platform now comprises 196 sites totaling 270 megawatts of operating capacity. The company stated this places it among the larger owners of operating commercial and industrial solar assets in the United States.

Michael Madia, Managing Director of Argo, said the investment represents another step in expanding the firm's commercial and industrial solar platform. Jason Zibarras, who founded Argo Infrastructure Partners, noted the deal reflects the firm's continued focus on deploying capital in what he described as the compellingly large mid-market infrastructure space.

The acquisition follows an agreement Argo reached in April 2026 to acquire an electric transmission and distribution business from UGI Corporation for approximately USD 470 million. That deal, along with the NuGen transaction, reflects the firm's stated commitment to distributed generation and long-duration energy transition infrastructure.

NuGen's Role and Background

NuGen Capital Management was founded in 2010 and is led by Chief Executive Officer and Founder David Milner. The company describes itself as focused on clean energy development and capital solutions in the United States, with activities spanning the financing, construction, ownership, and operation of energy projects. NuGen characterizes its work as contributing to the country's broader energy transition.

Milner said NuGen is proud to have developed and operated what he called a high-quality portfolio and expressed satisfaction with the partnership arrangement going forward.

He cited Argo's long-term approach to infrastructure investing and its demonstrated commitment to distributed generation as factors that made the firm a strong partner for NuGen.

Under the terms of the partnership established alongside the acquisition, NuGen will continue to support the long-term performance of the portfolio assets as part of Argo's platform.

Argo's Broader Investment Platform

Argo Infrastructure Partners LP was founded by Jason Zibarras and operates as an independent fund manager. The firm describes its investment philosophy as combining sound investment returns with responsible and sustainable investing. As of June 2026, Argo manages approximately $7.5 billion in assets.

Since 2013, Argo has invested what it describes as billions in high-quality infrastructure assets and businesses. The firm's investment portfolio spans multiple infrastructure categories, including utilities covering water, gas, and electric services, transmission, renewable solar and hydro energy, thermal and storage assets, and digital infrastructure.

The C&I solar segment represents one part of a broader infrastructure strategy that Argo has pursued across essential services sectors. The firm has positioned its approach around assets that provide essential services to communities over long operational lives, a characteristic it views as central to the risk and return profile it targets in the mid-market segment.

Commercial and Industrial Solar Context

Commercial and industrial solar, distinct from utility-scale generation or residential rooftop installations, typically involves solar installations at business facilities, industrial sites, and similar locations.

These assets often operate under long-term power purchase agreements or similar structures that provide revenue predictability over extended periods, characteristics that align with the long-duration infrastructure investment framework Argo has articulated as central to its strategy.

The Massachusetts and New Jersey sites acquired from NuGen add to Argo's existing geographic footprint in the C&I solar space. Both states have active renewable energy markets supported by state-level policy frameworks, though the press release did not detail the specific contractual or regulatory structures governing the acquired sites.

With 196 operating sites now under management in the C&I solar category alone, Argo's platform reflects a strategy of aggregating distributed assets at scale, a model that requires consistent operational management across a large number of individually smaller installations spread across multiple locations.
