Global Merging Unit Market size was valued at USD 370.0 Million in 2024 and is poised to grow from USD 389.98 Million in 2025 to USD 593.97 Million by 2033, growing at a CAGR of 5.4% during the forecast period (2026-2033).
The primary impetus for the merging unit market is the trend throughout the industry to migrate away from traditional hardwired instrument transformers to digital process buses that allow precision synchronized sampling of current and voltage signals. Merging units convert analog signals from current transformers or voltage transformer into sampled values that are compatible with IEC 61850-9-2. This allows for greater modularity of protective relaying and control systems, as well as real-time interoperability between systems. The merging unit market is significant because it provides utilities with improved reliability, requires less space to install than conventional wiring, and can be commissioned faster by using fibre-optic cables instead of bulky wiring, thereby reducing life-cycle costs. Vendors such as ABB (Schneider), Siemens and SEL have accelerated adoption through successful retrofitting of substations throughout Europe and Asia. In addition to facilitating the adoption of digital process buses, a growth factor in this market is standardization due to IEC 61850 compliance minimizing integration costs and providing greater incentive for utilities to utilize merging units in new greenfield projects and retrofits.
Additionally, utilities are dealing with both pressure from regulatory agencies to replace aging infrastructure and to create shorter replacement cycles, so they are using merging units to enable condition-based maintenance and faster fault isolation in order to improve reliability and lower outage costs. Likewise, rising renewable penetration increases system variability, creating demand for synchronized measurements to support protection, control and wide-area monitoring; pilot projects in China and India illustrate this. Vendors that offer cyber-hardened, interoperable products and analytics tie-ins will capture the largest opportunities.
How is AI Transforming Efficiency In The Merging Unit Market?
In substations, Merging Units convert transformer analogue signals into standardized digital values in a process bus architecture. The transition to digital substations has increased the need for interoperable Merging Units, as well as improved digital data flow. Incorporating AI can enhance efficiency by turning high-frequency sample data into actionable signals, and machine-learning algorithms can detect minor variances from acceptable ranges, making condition-based maintenance possible. Edge analytics can speed up the commissioning of these units and reduce the need for on-site diagnostics. Current vendors are embedding data preprocessing capabilities into Merging Units that will enable them to send validated and compressed data to protective and control systems in order to enhance the integration of renewable and distributed generation technologies. As an example, Siemens recently upgraded its Industrial AI Suite and Industrial Edge products, bringing AI and secure Edge Computing closer to the operational infrastructure. This enhancement to Merging Units will enable them to send pre-processed sampled data to local AI models, greatly enhancing fault detection, decreasing outage times, and accelerating the implementation of digital substations.
