Power Quality Equipment Market Size, Share, Growth and Forecast, 2026–2033

The global power quality equipment market size is likely to be valued at US$36.5 billion in 2026 and is projected to reach US$55.2 billion by 2033, growing at a CAGR of 6.1% during the forecast period from 2026 to 2033, driven by rising electricity demand, industrial automation, renewable-energy integration, data-center expansion, and grid modernization. Global electricity demand increased by about 800 TWh in 2025, with the International Energy Agency forecasting 3.6% growth in 2026 and 3.8% in 2027. Meanwhile, stricter grid-reliability requirements and growing inverter-based generation are increasing demand for power quality monitoring, harmonic mitigation, surge protection, and voltage-management equipment.

Driver: Rising electricity demand and increasing sensitivity of digital infrastructure

The principal driver for the power quality equipment market is the growing dependence on stable electricity across industrial, commercial, digital, and residential infrastructure. According to the International Energy Agency (IEA), global electricity consumption is projected to reach 30,700 TWh in 2027, compared with 28,600 TWh in 2025. Data-center electricity consumption increased by approximately 17% in 2025, adding around 70 TWh of demand.

According to the U.S. Department of Energy, citing the Electric Power Research Institute, data centers could account for up to 9% of U.S. electricity generation by 2030, compared with 4% in 2023. This rising dependence on sensitive electronic loads is increasing demand for power quality meters, surge protection devices, and harmonic filters to mitigate voltage sags, transients, harmonics, and interruptions.

Restraint: High installation costs and integration complexity

High upfront expenditure remains a structural restraint, particularly for small and medium-sized facilities and industrial users operating aging electrical systems. Advanced power quality equipment may require electrical audits, compatible switchgear, installation, commissioning, software integration, and ongoing maintenance, increasing the total cost of ownership.

Integration can become more difficult when equipment must be added to legacy distribution networks without disrupting operations. These requirements can lengthen procurement cycles and delay investment decisions, especially when customers cannot immediately quantify losses from poor power quality. Suppliers therefore need to demonstrate measurable improvements in equipment reliability, downtime reduction, energy efficiency, and maintenance costs to strengthen the investment case.

Opportunity: Renewable energy, electrification and intelligent power monitoring

The expansion of renewable generation, electric-vehicle charging, battery storage, and power-electronic equipment is creating new demand for intelligent power quality monitoring and automated corrective technologies. According to the European Commission, electricity-grid investment requirements could reach approximately €730 billion for distribution and €477 billion for transmission by 2040, creating opportunities for advanced monitoring and protection solutions.

As distributed energy resources increase, customers are moving beyond standalone meters toward systems that can identify disturbances and support corrective action. India offers particularly strong potential, with its power quality equipment market projected to reach approximately US$5.39 billion by 2033, supported by industrial electrification, renewable-energy deployment, and grid modernization.

Equipment Insights

The UPS segment is expected to be the largest, holding a market share of 27.2% in 2026, owing to its widespread use in guaranteeing a continuous power supply. The segment growth is further propelled by the growing demand for UPS in data centers, hospitals, and other critical infrastructure requiring an uninterrupted power supply.

Surge protection devices are estimated to be the fastest-growing equipment category as the penetration of sensitive electronic equipment, distributed energy systems, and connected infrastructure increases. Their relatively straightforward installation and broad applicability across residential, commercial, and industrial facilities support faster adoption. Increasing exposure to lightning events, switching transients, and voltage disturbances further strengthens replacement and retrofit demand.

Phase Insights

Three-phase equipment is estimated to hold approximately 60% of the global market in 2026, making it the leading phase segment. Its dominance reflects extensive use across manufacturing plants, industrial facilities, commercial buildings, and other high-capacity electrical systems. Three-phase architectures provide efficient power transmission and balanced load distribution, making them particularly suitable for motors, automation systems, HVAC equipment, and large electrical loads.

Single-phase equipment is estimated to register a 7.1% CAGR, supported by residential solar installations, small commercial facilities, distributed energy systems, and growing adoption of electronic loads. Its simpler installation requirements and suitability for lower-capacity applications are broadening its addressable customer base. Increasing residential electrification and distributed power generation are expected to sustain faster adoption of single-phase meters, surge protection, and related equipment.

End-user Insights

The industrial and manufacturing segment is projected to represent approximately 35% in 2026. Its leading position is supported by rapid industrialization, increasing automation, and stricter power quality requirements. Manufacturing plants increasingly rely on motors, variable-frequency drives, robotics, and automated production systems that are sensitive to voltage fluctuations, harmonics, and interruptions. As power disturbances can result in equipment damage, production downtime, and efficiency losses, industrial users are expected to maintain strong demand for power quality meters, harmonic filters, and surge protection devices.

The commercial segment is estimated to be the fastest-growing end-user category, supported by expanding data centers, healthcare facilities, offices, retail properties, and smart buildings. Increasing dependence on IT equipment, automation, HVAC systems, and electric-vehicle infrastructure is raising sensitivity to power disturbances. Commercial buildings also offer significant retrofit potential because existing electrical systems can be upgraded with monitoring and protection equipment without replacing the entire distribution infrastructure.
