- Stringent regulatory requirements and permitting delays, particularly for cross-border power connections between the U.S. and Canada, affecting timelines as per the latest Nexans update (July 2024).
Market Share by Type, 2025
Cables constitute the largest share of the North America subsea power grid system market by type, underscoring their pivotal role in power transmission between offshore assets. Transformers and switchgear are equally crucial, facilitating voltage management and system reliability, while connectors and variable speed drives support system flexibility. In 2025, increased investments in high-capacity, long-distance cable solutions reflect the surge in offshore wind farms and deepwater oil & gas sites, driving continued innovation and demand across all subsea grid system components.
Market Share by Application, 2025
Offshore oil & gas continues to command the largest application share of the North America subsea power grid system market, propelled by ongoing megaprojects in the Gulf of Mexico and North Atlantic. However, wind power is quickly closing the gap, buoyed by the expansion of U.S. and Canadian offshore wind capacity. The emergence of tidal and wave power projects signals a diversified future energy mix, increasingly supported by reliable and scalable subsea power grids tailored to variable offshore environments.
Market Revenue (USD Million), 2020-2035
The North America subsea power grid system market is projected to grow from USD 1,800 Million in 2020 to USD 5,650 Million by 2035, reflecting a CAGR of approximately 8.4%. This growth trajectory is anchored by significant projects in offshore wind and oil & gas, technological advancements in HVDC and hybrid power systems, and initiatives to modernize aging infrastructure. The market is further buoyed by the region's commitment to net-zero and expanded renewable portfolios, resulting in sustained investment through the forecast period.
YOY Growth Rate (%), 2020-2035
Year-over-year growth rates in the North America subsea power grid system market show healthy dynamics, peaking around major project commissioning years. The market achieves double-digit YOY growth between 2025 and 2028 as new wind and oil & gas grid projects come online, then stabilizes to a moderate 6-7% as the market matures with wider adoption of subsea power modules, digital solutions, and integration standards across the region.
Market Share by Region, 2025
In 2025, the United States dominates regional market share for subsea power grid systems, reflecting extensive offshore wind and oil & gas activities. Canada holds a strong position, particularly in the Atlantic with expanding offshore developments. Mexico’s share, while smaller, is set to grow as Pemex and international developers invest in deepwater assets in the Gulf of Mexico. This regional distribution underscores the predominance of U.S. projects, with strategic growth potential across North America.
Top Players Market Share, 2025
Market share among leading companies is dominated by ABB, Siemens Energy, and General Electric, who collectively hold over half the North American market for subsea power grid solutions. Their strong project pipelines, technological innovation, and strategic partnerships position them as key suppliers for both renewable and traditional energy subsea grids. Emerging players like Nexans, Baker Hughes, and TechnipFMC also contribute substantially, leveraging advancements in cables, connectors, and digital solutions for market expansion. Top Buyers Share, 2025
The largest buyers of subsea power grid systems in 2025 are offshore oil & gas majors and leading wind developers, reflecting the alignment of capital expenditure with offshore energy transition goals. End-users are increasingly seeking turnkey and digitally-enabled solutions, a trend evident in the growing role of system integrators and EPC contractors. This buyer landscape highlights the necessity of robust, scalable, and integrated grid support for high-value offshore assets.
