Power Monitoring and Fault-Detection Systems Market for Data Centers Size, Share, and Trends by Offering, Monitoring Function, Monitoring Point, Deployment Mode, Data Center Type, Current System (AC, DC) - Forecast to 2036

The global power monitoring and fault-detection systems market for data centers was valued at USD 2,460.0 million in 2025. The market is estimated at USD 2,850.0 million in 2026 and is projected to reach USD 11,040.0 million by 2036, at a CAGR of 14.5% during the forecast period 2026-2036. This report provides a detailed assessment of the market, covering market dynamics, measurement and detection technology, regulation and reporting, accuracy and detection performance, embedded telemetry, pricing, competition, and future growth opportunities.

The market includes the dedicated instruments, software, and services used to measure electrical conditions in data centers and to detect faults, from meters, circuit monitors, power quality analyzers, insulation monitors, and arc-flash, thermal, and partial discharge sensors to gateways, analytics and reporting software, and commissioning, calibration, and managed services. Telemetry built into power products such as 800V DC converters, busways, and breakers is counted with those products, while building management, IT and network monitoring, cooling, security, and utility revenue metering are excluded.

Commission Delegated Regulation (EU) 2024/1364, in force since 6 June 2024, obliges operators of data centers with 500 kW or more of installed IT power to track and report 24 key performance indicators on energy, ICT, and data traffic, plus electrical and cooling redundancy, using a common method. Reports are due each year on 15 May, and the rule allows operators to skip data they cannot collect for technical reasons if they explain why, a sign that many sites lack instrumentation. Rack power is also rising fast: according to Vertiv, AI clusters already reach 140 kW per rack, with 240 kW imminent and 600 kW on the horizon, and NVIDIA's 800 volt DC architecture, published in May 2025, is designed for racks of up to and beyond 1 MW. Demand is therefore moving from an operational choice to a compliance need, with a far higher cost attached to any single fault.

Market Dynamics

Regulatory reporting is the main driver of the power monitoring and fault-detection systems market for data centers, as the EU rating scheme makes measurement a condition of lawful operation and its annual cycle makes purchasing more predictable. Concentrated load is a second driver, as one rack now carries what a whole hall once did, so early warning of a failing joint is valued against the output at risk. The move to higher voltage DC distribution adds functions with no AC equivalent, such as insulation resistance and earth leakage monitoring on unearthed DC buses, and continuous asset health diagnostics are replacing periodic inspection in facilities that cannot take energized equipment out of service.

Telemetry embedded in power equipment is the main restraint on hardware demand, as power shelves, breakers, busways, and converters increasingly arrive with built-in measurement and a standard interface, so a separate meter is no longer bought. Examples include Advanced Energy Industries' Open Rack v3 power shelf with a Redfish-compatible controller and ABB's SACE Infinitus solid-state DC breaker with integrated monitoring. Combining data from equipment of different ages, protocols, and accuracy classes is another restraint. False alarms are a key challenge, because operators quickly disable or ignore systems that flag benign conditions, and practice for monitoring 800 volt DC systems is not yet settled.

Reporting-grade software and submission services offer a recurring opportunity tied to the annual reporting cycle. DC insulation monitoring, a new function with no legacy equipment to displace, tenant-level metering with billing-grade accuracy in colocation facilities, and predictive diagnostics on the installed base of electrical assets offer further openings. Key trends include measurement becoming a compliance function budgeted against external rules, telemetry becoming standard in power equipment, which shifts value toward software, and monitoring extending from AC to DC systems.

Segment Analysis

The report analyzes the market by offering, monitoring function, monitoring point, deployment mode, data center type, current system, and geography, helping stakeholders identify the most attractive growth areas.

By offering, the power monitoring and fault-detection systems market for data centers is segmented into hardware, software & analytics, and services, with hardware covering five instrument types from power meters to arc-flash and partial discharge sensors. Hardware is expected to account for the largest share in 2026, due to the number of devices needed for reporting and operations, the accuracy and traceability each compliance-grade instrument must provide, and the installation work involved. Software & analytics is expected to grow at the highest CAGR during the forecast period, as embedded telemetry leaves aggregation, normalization, and interpretation as the remaining task, reporting requires indicators calculated under a common methodology, and predictive diagnostics depend on analysis more than on measurement. Services demand will rise with commissioning, calibration, and reporting support.

By monitoring function, the power monitoring and fault-detection systems market for data centers is segmented into energy & power metering, power quality monitoring, branch & circuit-level monitoring, insulation & earth-fault monitoring, arc-flash & thermal detection, and asset health & predictive diagnostics. Energy & power metering is expected to account for the largest share in 2026, as it is the function reporting rules require most directly, and it also supports cost allocation and tenant billing. Asset health & predictive diagnostics is expected to grow at the highest CAGR, because loaded facilities cannot release equipment for inspection, the cost of an unplanned outage rises as load concentrates, and turning a failure into a planned intervention is judged against the output protected. Insulation & earth-fault monitoring is expected to grow strongly with DC distribution.

By monitoring point, the power monitoring and fault-detection systems market for data centers is segmented into utility entry & medium-voltage switchgear, uninterruptible power supply & energy storage, distribution panels & PDUs, busway & tap-off, and rack & branch circuit. Distribution panels & PDUs are expected to account for the largest share in 2026, as the distribution board is where load is divided and is the natural place to measure it, metering at this level is established practice, and instruments can be fitted there without interrupting rack supply. Rack & branch circuit monitoring is expected to grow at the highest CAGR, since the tenant boundary in multi-tenant facilities sits at the rack or branch circuit, measurement there supports billing and proof of contracted capacity, and device counts rise with tenancy instead of facility size. Medium-voltage switchgear monitoring grows with power quality needs.

By deployment mode, the power monitoring and fault-detection systems market for data centers is segmented into on-premises, cloud-based, and hybrid. On-premises deployment is expected to account for the largest share in 2026, as power monitoring sits within the facility's operational technology network, operators are reluctant to send protection-related data outside their own systems, and real-time decisions need low latency and high availability. Cloud-based deployment is expected to grow at the highest CAGR, supported by managing many sites from one platform, cross-site reporting, and analytics that draw on pooled data. Hybrid models keep real-time functions local and move reporting to the cloud.

By data center type, the power monitoring and fault-detection systems market for data centers is segmented into hyperscale, colocation & multi-tenant, enterprise, and edge. Hyperscale facilities are expected to account for the largest share in 2026, reflecting their capacity, dense instrumentation, and position above the reporting threshold. Colocation & multi-tenant facilities are expected to grow at the highest CAGR, as operators must split energy use between tenants for billing, prove contracted capacity and power quality at each delivery point, and support tenants' own reporting duties, none of which facility-level metering can do. Enterprise demand is expected to rise where sites exceed the reporting threshold, and edge facilities will grow from a small base.

By current system, the power monitoring and fault-detection systems market for data centers is segmented into alternating current monitoring and direct current monitoring. AC monitoring is expected to account for the largest share in 2026, supported by the large installed base of facilities that distribute AC power to the rack, mature instrument classes and standards, and continued construction of AC-based sites. DC monitoring is expected to grow at the highest CAGR, as higher voltage DC is adopted for racks beyond the limits of low-voltage DC and AC delivery, functions such as insulation resistance and earth leakage measurement have no AC equivalent, and early sites are heavily instrumented to build an operating record.
