March 18, 2025 — Hitachi Energy's Grid-enSure portfolio, designed to strengthen grid reliability and ease the integration of renewable power, has arrived at a pivotal moment for the global power grid system market. The suite anchors an effort to modernize India's energy infrastructure, but the pressures it addresses — aging networks, surging electricity use, and variable solar and wind output — extend well beyond South Asia. The Business Research Company's latest report values the sector at $12 billion in 2025 and projects it will reach $20.58 billion by 2030.
Market size and trajectory
The global power grid system market is projected to rise from $12 billion in 2025 to $13.34 billion in 2026, an 11.1% compound annual growth rate. The current expansion phase reflects years of generating-capacity additions, rapid urban electrification, higher industrial demand, and steady government funding for transmission and distribution networks.
Between 2026 and 2030, the compound annual growth rate is expected to edge up to 11.5%, bringing the market to $20.58 billion. The forecast assumes continued investment in renewable generation, rising electricity consumption from electric-vehicle charging, modernization of aging infrastructure, wider grid digitization, and new cross-border transmission links.
What is driving growth
Renewable energy buildout remains the most powerful engine. Solar and wind farms generate intermittently, so grid operators need advanced control systems, better forecasting, and greater flexibility to maintain frequency and voltage. That is driving investment in digital substations, automated protection schemes, phasor measurement units, and wide-area monitoring tools.
Electric vehicles are adding yet another layer of pressure. Charging creates sharp, localized demand peaks that distribution transformers and feeders were not designed to handle, prompting utilities to reinforce capacity. Urbanization is compounding the strain on overloaded networks, particularly in fast-growing economies where new connections are multiplying.
Aging infrastructure is becoming an equally pressing challenge in the United States and Europe. Much of the installed base was built decades ago and was never intended for the two-way power flows and dispersed generation that are common today. Grid-enhancing technologies — dynamic line ratings, advanced switching, flexible AC transmission systems — are moving into the mainstream as a direct response.
A US perspective on the forecast
For US readers, the market outlook is closely tied to federal policy. The Department of Energy's Grid Resilience and Innovation Partnerships (GRIP) program has earmarked roughly $10.5 billion for transmission upgrades, microgrids, and wildfire-hardening measures. In May 2024, FERC issued Order No. 1920, which requires transmission providers to plan over a 20-year horizon and account for shifting generation mixes. These initiatives create a receptive climate for equipment vendors and give multiyear growth projections solid institutional backing.
Hitachi Energy and the Grid-enSure launch
Hitachi Energy introduced Grid-enSure in October 2024. The portfolio targets system stability, asset protection, and renewable grid integration — areas that have grown more complex as inverter-based generation replaces traditional rotating machines. The company is promoting the suite as a cornerstone of India's energy transition, where long-distance transmission corridors are being built to move remote solar and wind power to load centers. India is adding renewable capacity faster than most markets, making it a proving ground for technology that will likely be deployed elsewhere.
The launch also highlights a broader industry shift. Rather than selling individual transformers or breakers, suppliers are increasingly bundling hardware with analytics, automation, and communication systems. That allows grid operators to monitor power flows in real time and respond to disturbances before they cascade into outages.
A notable acquisition
Consolidation is picking up as well. In October 2024, Power Grid Components Inc. (PGC), a US-based manufacturer of engineered grid hardware, acquired Canada's Vizimax Inc. Vizimax specializes in controlled switching devices that limit inrush currents and extend the life of transformers, reactors, and other high-value assets. The deal pushes PGC beyond its traditional insulators and hardware lineup into intelligent switching, a segment where demand is accelerating.
Who competes in this market
The competitive field spans global diversifieds, electrical equipment majors, and regional cable specialists. Siemens, General Electric, Mitsubishi Electric, Schneider Electric, ABB, Toshiba, Eaton, Prysmian, Nexans, and Sumitomo Electric all hold significant positions. Asian and emerging-market players such as LS Cable & System, TBEA, NARI Group, XJ Group, Pinggao, Meidensha, Larsen & Toubro, Bharat Heavy Electricals, Hyundai Electric, CG Power, Elsewedy Electric, KEC International, and C&S Electric round out the lineup.
Market segmentation
The report segments the industry by component, grid level, voltage, application, and end user. Component categories include power transformers, switchgear and circuit breakers, cables and overhead conductors, air-insulated and gas-insulated substations, protection and control systems, reactive power equipment, and grid communication and monitoring systems.
Grid-level segmentation covers transmission, distribution, and sub-transmission networks. Voltage tiers run from low and medium up to high, extra-high, and ultra-high. On the application side, the market is divided between onshore land-based grids and offshore or subsea systems. End users are grouped into utilities, industrial and commercial facilities, and renewable integration projects.
The component layer contains substantial sub-detail: transformer types such as distribution, power, instrument, auto, phase-shifting, and converter units; switchgear variants including GIS, AIS, vacuum, SF6, and hybrid models; and cable classifications spanning underground, submarine, and overhead conductor systems. Substations range from conventional transmission and distribution types to compact, mobile, digital, and HVDC converter stations. The study also tracks SCADA, EMS, DMS, fault detection and isolation, phasor measurement units, shunt and series compensation devices, STATCOM, synchronous condensers, power-line and fiber-optic communications, advanced metering infrastructure, and cybersecurity tools.
What to watch
Several technological themes are gaining momentum. Digital substations are shrinking equipment footprints while improving data collection. High-voltage direct-current lines are being extended to carry bulk renewable energy over long distances. Grid monitoring is moving from localized systems to enterprise-wide platforms, and cybersecurity spending is rising as operational technology networks become more exposed.
