Managing thousands of IoT devices and powering AI data centres are different operational challenges, but both require planning beyond the headline number: connected-device counts do not capture lifecycle risk, and annual electricity totals do not reveal local grid bottlenecks. A sound IoT program verifies identity and security posture before granting access, then maintains controls through retirement. For data centres, the International Energy Agency (IEA) estimated global electricity consumption at about 415 TWh in 2024 and projects about 945 TWh by 2030 in its base case; those figures cover all data centres, not AI alone.
How do you manage IoT devices at scale?
Treat fleet management as a security and operations lifecycle, not simply a way to connect more devices. Every device needs a known identity, an approved configuration, appropriately limited access, a path for authorized software updates, and an owner responsible for its support and retirement.

NIST’s SP 1800-36, published in November 2025 and updated in January 2026, describes trusted IP-based network-layer onboarding and lifecycle management. Its approach verifies device and network identity and device posture before issuing network credentials, then addresses secure posture throughout the device lifecycle. NIST says “scalable, automated mechanisms are needed to safely manage IoT devices throughout their lifecycles.” The guide demonstrates standards-based approaches using commercially available technology; it does not endorse a particular vendor or establish a single best architecture.

1. Define a security baseline, then profile each deployment
Start with the capabilities every device or device class needs. NIST’s technical capability catalog covers device identification, configuration, data protection, logical access to interfaces, software updates, cybersecurity-state awareness, and device security. Not every capability applies in the same way to every use case, so set requirements according to the device’s function, the data it handles, its network exposure, and the organization’s risk.

- Define what security-state information operators need to detect failures, drift, or compromise.
2. Onboard devices through a controlled process
Do not treat possession of a network address or a pre-shared credential as proof that a device is safe to join. Establish that the device and the network are the expected ones, check the device against the deployment’s posture requirements, and only then provision credentials and access. Where possible, automate repeatable checks so fleet growth does not depend on manual, device-by-device exceptions.
- Register: associate the device’s identity with its owner, intended purpose, location or deployment group, and support status.
- Verify: confirm device identity and network identity, then check the posture required for that device class.
- Provision: issue credentials and network permissions only after the checks succeed, using access limited to the device’s role.
- Validate: confirm that the device has the intended configuration and can be monitored and updated through authorized mechanisms.
This sequence reflects the trusted onboarding model in NIST SP 1800-36. The exact implementation depends on the protocols, network, device capabilities, and operating environment; the guide is a practice example, not a mandate to use one product or topology.
3. Operate the fleet as an ongoing control loop
After onboarding, keep the inventory aligned with reality and compare device state with the approved baseline. Monitor for missing devices, unexpected configuration changes, update failures, or a change in security posture. Define who can approve configuration changes and software updates, and retain enough status information to identify devices that need intervention.

Set an end-of-life process before deployment. When a device is transferred, replaced, or retired, remove its network access, revoke or disable its credentials, handle stored data according to policy, and update the inventory. Otherwise, the fleet record and access controls can outlive the equipment they were meant to govern.

How much electricity do AI data centres use?
There is no single global electricity figure for AI data centres in the cited estimates. The IEA’s 2025 analysis estimates and projects electricity use for all data centres, which serve AI and other workloads. It estimates about 415 terawatt-hours (TWh) of global data-centre electricity consumption in 2024—roughly 1.5% of global electricity—and projects about 945 TWh in 2030 in its base case. The 2030 value is a scenario projection, not a measurement or certainty.
| Measure | Geography and period | Figure | What it means |
|---|---|---|---|
| Data-centre electricity consumption | Global, 2024 | About 415 TWh; roughly 1.5% of global electricity | IEA 2025 estimate for all data centres, not AI alone. |
| Data-centre electricity consumption | Global, 2030 | About 945 TWh | IEA 2025 base-case projection for all data centres. |
| Electricity generation supplying data centres | Global, 2024 to 2030 | 460 TWh to over 1,000 TWh | IEA 2025 base-case projection of generation to supply data centres; this is a distinct measure from the consumption estimates above. |
| Data-centre electricity use | United States, 2023 | 176 TWh; about 4.4% of U.S. electricity | DOE figure announced in 2024, citing the Lawrence Berkeley National Laboratory report. |
| Data-centre electricity use | United States, 2028 | 325–580 TWh; about 6.7–12% of U.S. electricity | DOE’s 2024 summary of an LBNL projection range, not observed consumption. |
The global and U.S. figures should not be blended: they cover different geographies and years, and the forecasts depend on assumptions about future demand. The IEA’s 2025 analysis explicitly includes substantial uncertainty. Annual TWh also describes energy over time, not a facility’s peak power requirement in megawatts (MW), which is crucial when assessing a particular grid connection.
For the U.S. figures, see the Department of Energy’s 2024 summary of the LBNL report. For the global consumption estimates and base case, see the IEA’s energy-demand analysis; its separate energy-supply analysis discusses generation supplying data centres.
Will data centres put too much strain on the power grid?
They can create serious pressure in particular places, but a global annual total cannot establish whether a specific utility territory has enough capacity. Data-centre load is geographically concentrated, and a large facility’s connection can require local delivery capacity on a timescale that differs from broader forecasts of electricity supply.

A July 2024 U.S. Department of Energy Secretary of Energy Advisory Board report describes hyperscale data-centre connection requests in the 300–1,000 MW range or larger, with lead times of 1–3 years, as a challenge to local grid delivery capacity. These are the report’s described request sizes and connection context—not a typical timeline for every facility, utility, or country. The report is available as a DOE advisory report.
Three distinctions help make a grid assessment useful:
- Annual energy versus peak load: TWh totals describe energy consumed or generated over a year; MW describes power at a point in time and is more directly relevant to connection capacity.
- Global growth versus local constraint: adequate generation in aggregate does not mean the transmission and distribution network near a proposed site can deliver power when and where it is needed.
- Forecast versus committed project: a scenario for future demand is not the same as a specific connection request, an approved connection, or a completed facility.
What can utilities and data-centre operators do about rising demand?
Planning should connect a proposed facility’s load profile and connection schedule to the actual capacity and constraints of the local system. Because the DOE advisory report describes large requests as stretching local delivery capacity, utilities and operators need to identify connection requirements early rather than relying on an aggregate national or global forecast to answer a site-specific question.

For a project review, establish the expected peak MW, when the load will come online, and how quickly it may grow. Compare that schedule with the relevant utility’s available delivery capacity and planned network work. These questions make the discussion specific; the available global estimates do not determine the power needs or connection timeline of an individual facility.

Track supply as well as demand
The IEA’s 2025 base case projects global generation supplying data centres rising from 460 TWh in 2024 to over 1,000 TWh in 2030. In its analysis, renewables meet nearly half of additional data-centre demand over the next five years. That is a global scenario, not a guarantee of the electricity mix available to a particular site or a substitute for checking local grid conditions.
Use digital tools to improve grid operations
AI and other digital tools have a two-sided relationship with electricity systems: data centres add load, while digital tools may help operators with forecasting, optimisation, situational awareness, resilience, and risk management. The IEA’s 2026 report on modernising grids discusses these potential uses. They can support grid management, but they do not remove the need to assess physical network capacity and local connection constraints.
How to turn the evidence into an operational plan
For an IoT fleet, first define the device baseline and support responsibilities; then implement identity and posture checks before credential provisioning, and maintain inventory, monitoring, updates, access controls, and retirement procedures. For a data-centre project, keep annual energy forecasts separate from peak MW and distinguish global scenarios from the capacity and timing of the specific local connection.
