What Transmission Developers, Inc. - a Blackstone Portfolio Company does

Transmission Developers, Inc. (TDI) is a clean energy transmission infrastructure developer backed by Blackstone. The company identifies, develops, finances, constructs, and operates fully-buried underground and underwater high-voltage direct current (HVDC) transmission projects in the continental United States. Its portfolio is concentrated on two flagship projects in the Northeast: the 339-mile Champlain Hudson Power Express (CHPE), a $6 billion, 1,250 MW line delivering Canadian hydropower from Quebec to New York City and expected to be operational in May 2026; and the 154-mile New England Clean Power Link (NECPL), a 1,000 MW bidirectional HVDC line in Vermont connecting New England to Quebec's hydroelectric reservoirs. Projects are privately financed and serve government entities, utilities, and regulatory customers in the Northeast U.S. market.

TDI's core technical platform is HVDC transmission delivered via fully-buried terrestrial, marine, and urban cable systems, with DC-to-AC conversion handled at converter stations such as the Astoria Converter Station in New York City. The company operates as a vertically integrated project developer — managing regulatory, land, financing, engineering, procurement, and construction functions internally. Its go-to-market is enterprise field sales through direct engagement with government entities, utilities, and regulatory bodies, with customers anchored by long-term offtake and capacity contracts rather than recurring product or subscription sales.

The company's revenue model centers on large-scale, privately financed infrastructure project development. Revenue streams are tied to long-cycle construction milestones during the build phase and to long-duration offtake or capacity payments once projects reach commercial operation. TDI's executive and senior management teams collectively hold 365+ years of energy infrastructure experience drawn from Bechtel, MasTec, Kiewit, AECOM, Morgan Stanley, and the prior Blackstone portfolio company Sithe Global, providing the multi-disciplinary megaproject execution capability required to deliver $6 billion class HVDC infrastructure.

Core offering

Transmission Developers is a clean energy transmission project developer that develops, arranges financing for, constructs, and operates large-scale underground and underwater HVDC transmission infrastructure. The company's portfolio centers on the Champlain Hudson Power Express (CHPE), a $6 billion, 339-mile, 1,250 MW transmission line delivering Canadian renewable hydropower to New York City, and the New England Clean Power Link (NECPL), a 154-mile, 1,000 MW bidirectional HVDC line in Vermont. Projects are privately financed and installed in marine, terrestrial, and urban environments to avoid the negative impacts of overhead transmission.

Product overview

Transmission Developers is an energy transmission infrastructure development company that operates as a unified project development and management service rather than a software product platform. The company has a portfolio of two major transmission infrastructure projects: the Champlain Hudson Power Express® (CHPE), a 339-mile 1,250 MW underground/underwater transmission line from Canada to New York City expected to be operational in May 2026, and the New England Clean Power Link® (NECPL), a 154-mile 1,000 MW underground HVDC transmission line in Vermont. Both projects are fully buried transmission lines that deliver clean renewable energy to their respective markets. The company leverages 365+ years of combined experience across executive and senior management teams to develop these projects from conception through construction.

Brands

• Champlain Hudson Power Express®: A 339-mile fully-buried underground and underwater transmission line to transport 1,250 MW of baseload clean, renewable hydropower from Canada to New York City. Will provide 20% of New York City's annual electricity needs when fully operational starting May 2026.
• New England Clean Power Link®

Products and services

• Champlain Hudson Power Express (CHPE) A 339-mile fully-buried underground and underwater transmission line to transport 1,250 MW of baseload clean, renewable hydropower from the U.S.-Canadian border to New York City. This $6 billion megaproject will provide 20% of New York City's annual electricity needs when fully operational starting in May 2026, and includes the first-ever conversion of a fossil-fuel site into a grid-scale zero-emissions facility in New York City.
• New England Clean Power Link (NECPL) A 100% buried, approximately 154-mile underground transmission line from the Canadian border to Ludlow, Vermont. The project provides 1,000 MW of underground bidirectional HVDC transmission capacity to connect New England with Quebec's extensive reservoirs and storage, providing clean power to the New England market.
• Transmission Project Development Services World-class industry expertise across multiple disciplines including transmission project development, financing, engineering, procurement, and construction management in marine, terrestrial, and urban environments.

Emerging players

• Pattern Energy: Renewable energy developer and owner/operator with transmission-enabled projects including Pattern Energy's SunZia HVDC line. Comparable as a clean-energy transmission-enabled infrastructure developer, though with primary focus on renewable generation rather than transmission.
• Northland Power: Developer of renewable and transmission infrastructure including offshore wind in the Northeast. Comparable as a clean-energy infrastructure developer with Northeast U.S. focus and growing exposure to grid-scale transmission interconnections.

Direct peers

• Anbaric Development Partners: Specializes in underwater and underground electric transmission development in the Northeast U.S. Highly comparable to TDI's fully-buried HVDC approach with shared focus on marine routes serving Northeast load centers.
• ITC Holdings: Pure-play independent transmission owner and operator (subsidiary of Fortis Inc.) operating high-voltage transmission systems across multiple U.S. regions. Directly comparable business model of developing and operating transmission infrastructure as a regulated utility.
• LS Power: Privately-held developer, owner, and operator of transmission and power infrastructure across North America. Most directly comparable to TDI as a transmission-focused project developer with both greenfield development and asset ownership capabilities.

Broad incumbents

• Avangrid: Iberdrola-owned energy company with significant electric transmission and distribution operations in the Northeast U.S. (NYSEG, RG&E, UI). Comparable in owning T&D infrastructure serving the same Northeast markets TDI targets, though far larger and more diversified.
• NextEra Energy Transmission: Transmission subsidiary of NextEra Energy, one of North America's largest electric infrastructure companies. Comparable in developing and acquiring high-voltage transmission assets, with broader portfolio including generation and renewables.
• Eversource Energy: Largest energy company in New England operating electric transmission, distribution, and natural gas delivery. Serves overlapping Northeast U.S. customers and partners on transmission build-outs in the same geography as TDI's NECPL project.

Others

• Hydro-Québec: Canadian provincial utility supplying the hydropower that flows through TDI's CHPE and NECPL lines. Acts as the upstream counterparty/supplier to TDI's transmission business and is integral to both projects' offtake structure.

Regional players

• National Grid: International T&D utility with significant operations in the Northeastern U.S. and direct involvement in New England transmission planning. Comparable as an owner/operator of Northeast transmission infrastructure though operating primarily as a regulated incumbent rather than developer.
