Market Driver

Global Grid & Industrial Modernization

Global efforts to modernize power grids and industrial infrastructure are driving the demand for laminated busbars as efficient and reliable power distribution components. In July 2025, Ofgem approved a USD 30.5 billion investment to modernize the UK’s energy infrastructure in support of its green transition.

This includes approximately USD 19.1 billion allocated to gas systems and USD 11.3 billion for upgrades to the high-voltage electricity grid. The funding represents the first phase of a broader USD 101.7 billion initiative aimed at strengthening the electricity network and shielding UK households from the volatility of the global gas industry.

Upgrades in switchgear, substations, and data centers require low-inductance solutions to handle high current loads with minimal energy loss. Laminated busbars are being adopted to improve thermal management, reduce wiring complexity, and ensure compact system design.

Electrical systems must accommodate higher performance standards and greater operational resilience as clean energy systems and smart infrastructure expand. Industrial automation and digital control systems are also increasing the need for stable and efficient electrical distribution.

Market Challenge

Supply Chain and Cost Volatility

A key challenge in the laminated busbar market is managing the unpredictable pricing of raw materials such as copper, aluminum, and insulating components. Fluctuations in global supply chains and commodity markets are creating instability in production costs, making it difficult for manufacturers to maintain consistent pricing. These pressures reduce profit margins and complicate long-term planning for both suppliers and end users.

To address this challenge, market players are diversifying sourcing strategies, entering long-term contracts with material suppliers, and optimizing material usage through design innovation. Companies are also adopting cost-tracking systems and lean manufacturing practices to improve cost visibility and operational efficiency.

Market Trend

Laminated Busbar Market Regional Analysis

Based on region, the market has been classified into North America, Europe, Asia Pacific, the Middle East & Africa, and South America.

North America laminated busbar market accounted share of around 36.55% in 2024, with a valuation of USD 341.5 million. This dominance is largely attributed to the rapid growth of cloud computing, AI workloads, and digital services, which is fueling a surge in hyperscale and enterprise data center construction across North America.

The U.S. Department of Energy (DOE) reports that data center electricity demand has tripled over the past decade and is expected to double or triple again by 2028. In 2023, data centers accounted for approximately 4.4% of total U.S. electricity consumption, and projected to rise to between 6.7% and 12% by 2028.

According to the report, total electricity use by data centers increased from 58 terawatt-hours (TWh) in 2014 to 176 TWh in 2023, with estimates to reach between 325 and 580 TWh by 2028.

These facilities demand compact, high-reliability power distribution systems to ensure continuous operation and energy efficiency. Laminated busbars are being increasingly integrated into power distribution units (PDUs), server racks, and uninterruptible power supply (UPS) systems, due to their low electromagnetic interference (EMI) and space-efficient design. Additionally, their ability to support effective thermal management makes them well-suited for modern data center environments.

The Asia Pacific laminated busbar industry is poised for significant growth at a robust CAGR of 6.94% over the forecast period. This growth is attributed to the large-scale expansion of solar and wind energy projects across the region, along with the increasing adoption of battery energy storage systems (BESS).

Scheduled for completion by early 2027, these projects are projected to produce a combined total of 1,158 GWh of clean electricity each year.

Laminated busbars play a vital role in these applications, particularly in inverters, junction boxes, and battery racks, due to their ability to efficiently manage high current loads. Their use also enhances system stability and minimizes electrical losses, which are essential for the reliable operation of renewable energy systems in varied environmental conditions in the region.

Regulatory Frameworks

• In the U.S., laminated busbars are regulated under the National Electrical Code (NEC), published by the National Fire Protection Association (NFPA 70). UL 857 governs safety standards for busways, while UL 508 applies to industrial control panels using busbars. These standards specify current ratings, insulation, spacing, and thermal rise requirements.
• In the UK, laminated busbars are regulated under BS EN 61439, the British standard harmonized with IEC requirements for low-voltage switchgear and controlgear assemblies. The regulation mandates type-testing of the entire assembly, including thermal performance, dielectric strength, and short-circuit durability. Components must also meet BS EN 60947 for individual low-voltage devices.
• In China, laminated busbars are subject to China RoHS II regulations, enforced under SJ/T 11364 and GB/T 26572‑2011, which restrict hazardous substances like lead, mercury, and cadmium in electrical products. Additionally, if used in certified assemblies, busbars fall under the China Compulsory Certification (CCC) system for safety and electromagnetic compatibility.
• Japan regulates laminated busbars through Japanese Industrial Standards (JIS) aligned with International Electrotechnical Commission (IEC) 61439. The Ministry of Economy, Trade and Industry (METI) enforces RoHS-equivalent environmental laws, requiring low hazardous material content. Busbars must comply with structural and dielectric tests to ensure safety in control panels, UPS systems, and battery packs.
