The industrial digital substation market size is expected to see strong growth in the next few years. It will grow to $5.58 billion in 2029 at a compound annual growth rate (CAGR) of 7.4%. The growth in the forecast period can be attributed to the adoption of Industry 4 and digital transformation in power systems, rising demand for sustainable and energy-efficient infrastructure, continued expansion of smart grid and advanced metering infrastructure, enhanced cybersecurity measures for protecting critical infrastructure, and continued emphasis on reducing carbon emissions and improving energy efficiency. Major trends in the forecast period include the expansion of smart grid technologies, the integration of artificial intelligence (AI), the adoption of edge computing, the deployment of digital twin technology, the use of internet of things (IoT) devices, and advancements in cybersecurity.

The rising demand for electricity is expected to drive growth in the industrial digital substation market. This increase in electricity demand is attributed to factors such as urbanization, industrialization, and the growing use of electric technologies and devices. Industrial digital substations improve the efficiency, reliability, and automation of power distribution and management in industrial settings. For example, in January 2024, the International Energy Agency, based in France, reported a 2.2% rise in global electricity demand in 2023, with China experiencing a 6.4% increase. Over the next three years, global demand is projected to grow at an average annual rate of 3.4%, with India leading major economies, having seen a 7% increase in 2023 and expected to grow by over 6% annually through 2026. Thus, the increasing electricity demand is fueling the expansion of the industrial digital substation market.

Companies in the industrial digital substation market are focusing on innovative products like process interface units (PIUs) to enhance the adoption of digital substations. These units improve efficiency, flexibility, and maintainability while supporting advanced automation and communication. A process interface unit (PIU) connects field devices to the control system, converting physical signals into digital data for monitoring and control. For instance, in March 2024, Hitachi Energy Ltd., a Switzerland-based technology firm, introduced SAM600 3.0, a new PIU designed to advance digital substation technology. This unit combines three separate units into a single modular device, functioning as a merging unit, a switchgear control unit, or both. This integration simplifies installation and maintenance for utilities and converts analog signals into digital data for efficient current and voltage distribution across the substation.

In September 2023, EFACEC Power Solutions SGPS S.A., a Portugal-based electronics manufacturing company specializing in industrial digital substations, entered into a partnership with Red Electrica Corporacion SA. The collaboration aims to optimize the electrical network in Spain and the Balearic Islands through a €25 million ($26.26 million) contract, which includes the supply of 12 power transformers. This agreement is focused on improving the resilience and efficiency of the region's energy transmission infrastructure. Red Electrica Corporacion SA (REC), a Spain-based company, specializes in electricity transmission services and the operation of electric networks.

An industrial digital substation is an advanced version of a traditional electrical substation that utilizes digital technologies and sophisticated communication protocols to improve the management, control, and protection of power distribution in industrial settings. These substations integrate intelligent electronic devices (IEDs), digital sensors, and automated control systems to replace conventional analog equipment, enabling real-time monitoring, data analysis, and remote operation.

The main components of an industrial digital substation include the substation automation system, communication network, electrical system, and monitoring and control system, among others. The substation automation system comprises a network of hardware and software designed to manage, monitor, and optimize substation operations, enhancing efficiency, reliability, and safety. These components are organized by architecture into process, bay, and station levels. Industrial digital substations operate across various voltage levels - low, medium, and high - and can be installed as new or refurbished systems.
