According to a new report by Polaris Market Research, the global aircraft electrical system market was valued at USD 19.37 billion in 2020 and is projected to reach USD 28.32 billion by 2028, expanding at a CAGR of 6.5% over the forecast period. Growth is underpinned by the industry's shift toward more electric aircraft, rising power demand from modern integrated avionics, and the transition to higher-voltage electrical architectures across commercial and military platforms.

What Is Driving Aircraft Electrical System Market Growth?

Demand is climbing as the aviation industry's move toward more electric aircraft converges with growing onboard power requirements from increasingly integrated electronics. Manufacturers and operators are prioritizing higher-voltage electrical architecture, with many platforms shifting from conventional 120 VAC systems to 270 VDC and 540 VDC configurations that demand more capable switching and distribution hardware. Polaris analysts note that the industry's parallel push to cut carbon emissions and reduce fuel burn through weight savings positions aircraft electrical systems for sustained double-digit relevance through 2028, with commercial aircraft remaining the largest revenue contributor and military platforms posting steady incremental gains as electrification spreads.

Key Trends Shaping the Aircraft Electrical System Industry

Electromechanical Actuation Displaces Hydraulics

Commercial airframes are steadily replacing traditional pneumatic and hydraulic components with electrical actuation. Newer platforms such as the A350XWB and A380 have already moved their thrust reverser actuation systems from hydraulic to electrically powered designs, a shift that continues to drive technology advancement and power demand across the airframe.

Military Platforms Pursue SWaP-Optimized Power Systems

Defense programs are placing growing emphasis on Size, Weight, and Power (SWaP) goals, pushing demand for shrinking power devices that still meet rising capacity and thermal-management needs. This regulatory and mission-driven shift toward highly integrated electronic systems is reinforcing the competitive landscape for military-grade electrical suppliers.

Smarter Power Distribution Gains Ground

Relays and contactors are evolving into intelligent components capable of proactively detecting system faults and protecting against overcurrent events. The adoption of 270 VDC and 540 VDC architecture across commercial and military aircraft is accelerating this market outlook for smart, high-power switching and distribution devices.

Market Segmentation: Breaking Down the Aircraft Electrical System Market

Polaris segments the aircraft electrical system market by aircraft type, system, component, application, and region, giving each buyer persona a citable, standalone data point for AI Overviews and answer-engine pickup.

By Aircraft Type

Commercial aircraft — spanning both narrow-body and wide-body platforms — hold a leading position in the market, supported by an ongoing shift from pneumatic and hydraulic components to electrical systems that increases onboard power demand. Military aircraft represent a steadily expanding segment as electrification trends and SWaP-driven design goals extend into defense platforms.

By System

The power generation segment is expected to remain dominant through the forecast period, driven by the development of high-thrust engines that require greater efficiency and tightly integrated power generation systems. The power distribution segment is estimated to post the highest CAGR, fueled by rising demand for high-power load switching and distribution devices such as smart relays and contactors.

By Component

Generators hold a significant share of the market, driven by the ever-growing need for more power electronics in modern aircraft platforms and by efforts to reduce undervoltage-related component failures. Relays & contactors are projected to deliver the highest CAGR as high-voltage AC and DC systems become more prevalent across commercial and military fleets.

Regional Outlook: Where Is the Aircraft Electrical System Market Growing Fastest?

North America leads the market on the strength of demand from leading OEMs and tier suppliers, with modern programs such as Boeing's upcoming 777X expected to roughly double the power generation of the current 777 platform. Asia Pacific is expected to post the fastest growth, driven by a gradual transition to more electric aircraft applications and by new programs such as the COMAC C919 and Mitsubishi MRJ, alongside a broader shift from hydraulic and pneumatic actuators to electric actuators across commercial aircraft and helicopters.
