The rising energy demand is expected to drive the growth of the electric power substation automation market in the coming years. Energy demand refers to the amount of energy required by consumers, industries, and other sectors, and is increasing due to population growth, urbanization, and global industrialization. Electric power substation automation efficiently manages and optimizes power distribution, enhancing grid reliability, minimizing downtime, and reducing operational costs. This capability enables rapid response to issues, improving the reliability of the power supply. For instance, in September 2025, the International Energy Agency, a US-based intergovernmental organization, reported that total net electricity generation in the OECD reached 922.6 TWh in June 2025, representing a 1.4% increase compared to June 2024. Therefore, the growing energy demand is contributing to the expansion of the electric power substation automation market.

Major companies operating in the electric power substation automation market are focusing on developing advanced solutions, such as digital substations, to improve operational efficiency, enhance reliability, and enable real-time monitoring and control. Digital substations involve the integration of intelligent electronic devices (IEDs), sensors, and communication protocols like IEC 61850, facilitating seamless data exchange and faster decision-making within substation infrastructure. For instance, in January 2024, Hitachi Energy Ltd., a Switzerland-based energy industry company, launched the SAM600 3.0, a next-generation digital substation solution. Designed to retrofit conventional instrument transformers into modern process bus systems, the SAM600 supports high-speed Ethernet-based messaging and offers enhanced protection, automation, and control capabilities, enabling utilities to achieve safer, more responsive, and scalable substation operations.

In February 2025, Schneider Electric SE, a France-based digital automation and energy management company, acquired a controlling 75% stake in Motivair Compressors Ltd. for an undisclosed amount. Through this acquisition, Schneider Electric SE aims to strengthen its electric power substation automation capabilities by integrating Motivair’s advanced liquid cooling and thermal management solutions, enhancing operational efficiency, system reliability, and digital infrastructure performance across high-voltage and utility-grade electrical distribution networks. Motivair Compressors Ltd. is a US-based company that provides liquid cooling and thermal management solutions for data centers, industrial applications, and high-power electrical systems.
