AI data centres will double power use by 2030 — how Denka Platinum cuts the hidden losses
The IEA expects data-centre electricity use to reach about 945 TWh by 2030. Denka Platinum (Denka®), a clip-on high-frequency passive filter, targets the losses that power electronics create along the way.

Electricity demand from artificial intelligence is rising fast, and every kilowatt-hour passes through power electronics that also create high-frequency noise and losses. Denka Platinum (Denka®) is a clip-on high-frequency passive filter designed to reduce those losses on existing circuits — without rewiring or downtime. Here is what the latest IEA figures mean, and where Denka Platinum fits.
How much electricity will data centres use by 2030?
The International Energy Agency projects that data centres will use about 945 TWh by 2030, up from roughly 415 TWh in 2024 — and every one of those kilowatt-hours runs through the kind of electronic load that Denka Platinum is built to treat. The IEA’s Energy and AI report (April 2025) puts that 2030 figure slightly above Japan’s entire current electricity use, with AI-optimised data centres growing fastest.
| Year | Global data-centre use | Comparison |
|---|---|---|
| 2024 | ≈ 415 TWh | — |
| 2030 (projection) | ≈ 945 TWh | Slightly more than Japan’s total electricity use today |
Why do modern electronic loads waste electricity?
Servers, UPS systems, LED lighting and variable-speed drives switch current thousands of times per second, injecting harmonic currents and high-frequency noise that heat cables, transformers and motors — losses that Denka® passive filters are designed to absorb. Because these losses are spread across hundreds of circuits, they are rarely measured and rarely treated.
Where does Denka Platinum help?
Denka Platinum reduces conducted high-frequency noise (150 kHz–30 MHz) on the circuits feeding electronic loads, so less energy is lost as heat. The plates clip onto existing circuits; independent tests at KU Leuven / EnergyVille measured 13–15% high-frequency attenuation per plate, and at Saj Ceramics current distortion on one mill fell from 24.5% to 9.8%.
The IEA also notes that data centres will be only about a tenth of global demand growth to 2030 — less than industrial motors, air conditioning or electric vehicles. The same power-quality losses therefore appear in factories, buildings and cooling plants, which is where most Denka Platinum high-frequency passive filter installations are verified today.
What should operators do first?
- Measure before you expand: a power-quality survey (THD, power factor, load profile) shows where losses concentrate.
- Treat distortion as an energy cost, not only an equipment-protection issue.
- Verify savings properly with a production- and weather-adjusted baseline, as in our verified Denka Platinum results.
Frequently asked questions about Denka Platinum
What is Denka Platinum?
Denka Platinum (Denka®) is a clip-on Ni-Zn ferrite-ceramic high-frequency passive filter (150 kHz–30 MHz) developed by Why Inc. in Tokyo that attenuates conducted electrical noise from inverters and drives to reduce losses and protect equipment.
Is Denka Platinum related to Denka Company Limited?
No. Denka Platinum (Denka®) is a power-quality and energy-efficiency product of Why Inc. (Why Group) and has no connection with Denka Company Limited, the Japanese chemical manufacturer.
Can Denka Platinum be used in data centres?
Denka Platinum treats the same electronic loads found in data centres — UPS systems, drives and switch-mode power supplies — but its verified results so far come from industrial and commercial sites, so we always start with an on-site measurement.
How do I know if my site has high-frequency losses?
A short power-quality survey measuring total harmonic distortion, power factor and the load profile at your main boards shows whether high-frequency distortion is high enough for Denka Platinum to make a measurable difference.
