Marsons and Cleanhill Partners plan to form a joint venture to scale power transformer manufacturing in North America. The Marsons board approved the formation of this JV on October 6, 2026.
Joint venture structure and scope
The proposed collaboration between Marsons and Cleanhill Partners is aimed at expanding power transformer manufacturing capacity in North America. The joint venture represents a strategic move to address the growing demand for power infrastructure equipment in the region. The entity will be formed as a limited liability company in the United States.
| Parameter | Details |
|---|---|
| Companies involved | Marsons and Cleanhill Partners |
| Nature of arrangement | Joint venture (LLC) |
| Focus area | Power transformer manufacturing and sales |
| Target geography | United States and Canada |
| Approval date | October 6, 2026 |
The partnership signals Marsons' intent to establish a manufacturing presence in North America through a collaborative structure with Cleanhill Partners. Power transformers are critical components in electrical transmission and distribution networks, and the joint venture is positioned to serve this segment in the North American market.
Market context and operational roadmap
North America faces a significant transformer supply gap with lead times exceeding 24 months. Utilities and renewable energy developers are increasingly focused on supply-chain diversification. Marsons is currently executing transformer orders for major U.S. renewable energy and utility projects, including GSUs up to 200 MVA and pad-mounted units across multiple locations.
The newly formed entity will initially focus on importing, marketing, selling, distributing, and servicing Marsons transformers in the United States and Canada. In due course, the joint venture plans to manufacture transformers specifically for these markets. A longer-term vision includes full-scale transformer manufacturing in North America to address demand from grid modernization, renewable energy expansion, and data center power requirements.
Company profiles
Marsons Limited is an India-based EHV power transformer manufacturer with 70 years of engineering heritage. It is the only EHV transformer manufacturer in Eastern India and the Northeast Region and the largest by installed capacity in that area. The company operates a 45,000 square-meter manufacturing facility with current annual capacity of 12,000 MVA, undergoing expansion to 26,000 MVA. Marsons holds approvals from PGCIL and NTPC and specializes in transformers rated from 11 kV to 345 kV and beyond.
Cleanhill Partners is a New York-based private equity firm focused on energy transition and digital infrastructure. Its portfolio includes Jule Power (battery energy storage) and FTC Solar (solar tracker systems). The firm recently announced the sale of EPC Power, a manufacturer of power conversion systems for data centers and microgrids.
What the Numbers Show
Marsons' current capacity of 12,000 MVA is set to more than double to 26,000 MVA through ongoing expansion. This capacity increase aligns with the joint venture's goal to transition from project-by-project execution to becoming a strategic infrastructure partner in North America, where supply constraints persist due to long lead times exceeding two years.
