The electric power transmission, control, and distribution market size is expected to see strong growth in the next few years. It will grow to $4.2 trillion in 2030 at a compound annual growth rate (CAGR) of 5.9%. The growth in the forecast period can be attributed to expansion of high-voltage transmission lines, deployment of smart grid technologies, adoption of advanced monitoring and control systems, increasing electrification of commercial and residential sectors, integration of renewable energy sources into grids. Major trends in the forecast period include integration of smart grid and automated control systems, deployment of high-voltage transmission and substation upgrades, adoption of advanced voltage regulation and switchgear solutions, expansion of medium- and low-voltage distribution networks, implementation of grid control and monitoring systems.

The surging demand for electricity is poised to drive the expansion of the electric power transmission, control, and distribution market in the foreseeable future. Electricity, defined as the flow of electric charge through conductors, serves as the power source for various electrical devices and systems. Power transmission, control, and distribution play a critical role in the efficient and safe delivery of electricity from generation sources to end-users while upholding reliability. For example, in September 2023, as reported by the International Energy Agency, an autonomous intergovernmental organization headquartered in France, Colombia recorded a total net electricity production of 7 terawatt-hours (TWh) in June 2023, marking a 1.1% increase on a year-to-date basis. This underscores the growing demand for electricity and its pivotal role in driving the growth of the electric power transmission, control, and distribution market.

Major companies in the electric power transmission, control, and distribution market are increasingly focused on developing advanced power protection relays to enhance the reliability, adaptability, and stability of India's power distribution grid in response to evolving energy demands. An advanced power protection relay is a sophisticated device designed to monitor electrical systems for abnormal conditions, such as overcurrents or faults, and automatically trip circuit breakers to isolate and protect equipment from damage. For example, in October 2024, Hitachi Energy, a Switzerland-based technology company, launched the Relion REF650, specifically designed for India's medium-voltage power distribution grid. This product offers enhanced modularity, robust security features, and a simplified user interface to address the dynamic power quality requirements of utilities and industrial facilities. The relay plays a crucial role in supporting the integration of renewable energy sources and electric vehicle (EV) charging infrastructure, thereby contributing to a more stable and adaptable electricity distribution network.

In August 2025, SP Group, a Singapore-based energy and utilities company, acquired Power Automation Pte Ltd. for an undisclosed amount. Through this acquisition, SP Group aims to strengthen its substation automation and smart grid capabilities by integrating Power Automation’s expertise in power systems control, protection systems, and digital energy solutions. Power Automation Pte Ltd. is a Singapore-based company specializing in substation automation, advanced distribution management, and mission-critical energy automation solutions for utility grids.
