The Cost of Power
Switzerland pairs a high-value industrial base with the second-most-expensive electricity in Europe — only the Netherlands is higher. Large industrial users pay around CHF 0.16/kWh all-in, while the business median sits at CHF 0.237/kWh — roughly 2.3× the French rate and about 135% of the European average. For a pharma facility, precision plant, data centre, or commercial estate, the price of a kilowatt-hour is the single biggest reason to stop wasting any.
The grid-cost component alone has risen around 50% since 2015, and because every qualifying site — any consumer above 100 MWh a year, on the free market since 2009 — is exposed to wholesale prices, a structural energy reduction flows straight to the bottom line. The usual argument that “industrial power is cheap, efficiency doesn’t move the needle” simply does not hold here. Every percentage point of wasted current is charged at one of the highest unit rates in Europe.
| Who pays | Typical price | Notes |
|---|---|---|
| Large industrial (>20 GWh/yr, all-in) | ~CHF 0.16/kWh | Second-highest in Europe; grid-cost component ~6.75 Rp/kWh |
| Business median (all-in) | CHF 0.237/kWh | ~135% of the European average; commercial estates feel the tariff acutely |
| Commercial-weighted (typical qualifying site) | ~CHF 0.22/kWh | The blended rate most mid-sized C&I sites actually pay |
| Households (ElCom H4 median) | ~CHF 0.29/kWh (2025) | Falling to ~CHF 0.277/kWh in 2026 — among the higher residential rates in Europe |
Large-industrial and grid-cost figures are from Avenir Suisse (2024); the business median is from GlobalPetrolPrices (Sep 2025); the household figure is the ElCom H4 reference-household median unit rate. Figures are current as of 2024–2026 and are revised regularly — verify against ElCom electricity prices (strompreis.elcom.admin.ch) and your distribution operator at the time of reading. All prices are per kWh and exclude site-specific demand and reactive charges.
How You’re Billed
The headline centime-per-kWh is only part of the story. A metered Swiss site pays for the energy itself, for the networks that deliver it, for taxes and levies — and, critically for power quality, for the capacity it places on the grid and for the reactive energy it draws. Those last two move directly when you correct power factor.
| Component | What it is | Cut by power quality? |
|---|---|---|
| Energy (wholesale / commodity) | The kWh you consume, at the traded price — free market for sites above 100 MWh/yr | Indirectly — lower network losses |
| Grid charges (Netznutzung) | The cost of delivering power over the network; ~6.75 Rp/kWh and up ~50% since 2015 | Partly |
| Taxes & levies | Federal grid surcharge and cantonal/municipal charges | No |
| Demand / capacity charge (kW / kVA) | A charge on the demand and capacity you place on the network | Yes — lower apparent power means a lower charge |
| Reactive-energy charge (Blindenergie, kvarh) | Reactive energy billed once it exceeds the cos φ threshold — ~1.81 Rp/kvarh at transmission (2026), with DSO charges on top | Yes — power factor correction cuts it directly |
So the answer to two questions Swiss operators often ask: yes, you are billed for demand and capacity — through the apparent-power demand charge — and yes, you are billed for poor power factor, through the reactive-energy charge (Blindenergie) once you slip below the cos φ threshold. Both fall as power factor rises toward unity, which is exactly what correction delivers.
Power Factor & Regulation
Swiss distribution operators and the transmission grid bill reactive energy once a site’s power factor falls below a threshold — commonly cos φ 0.9, though the exact threshold and rate vary by operator. At transmission level, Swissgrid charges reactive energy at roughly 1.81 Rp/kvarh in 2026 (falling to 1.62 Rp in 2027), with each of the country’s ~630 distribution operators applying its own reactive billing on top. A site running at 0.85–0.92 power factor — typical for motor- and drive-heavy plants — therefore pays a recurring charge that disappears the moment it is corrected to 0.98+, alongside lower demand and capacity fees.
On harmonics and supply quality, Swiss connections must hold voltage quality within EN 50160 and manage harmonic emissions under the IEC 61000 series (including IEC 61000-3-2/-3-12 and -2-4), with low-voltage equipment following the Swiss NEV ordinance, which mirrors the EU Low-Voltage and EMC Directives. As inverter-based solar PV, variable-speed drives, rectifiers and non-linear UPS multiply on Swiss sites, staying inside those limits increasingly requires active harmonic filtering — not just a one-off survey.
Reactive-energy billing below the cos φ threshold is set per operator — Swissgrid at transmission level and each distribution operator (Netzbetreiber) on the local network; voltage-quality limits follow EN 50160 and harmonic emissions follow the IEC 61000 series, with low-voltage equipment under the Swiss NEV. Confirm the charge, threshold and limits that apply to your connection with your distribution operator, and check current tariffs with ElCom and the VSE — they vary by region and are updated periodically.
Why Power Quality Matters Here
Three structural forces make power quality a Swiss boardroom issue, not just an engineering one. First, the tariff — already covered, and the second-highest in Europe. Second, the loads: Switzerland’s qualifying base is unusually high-value rather than high-volume — pharma and biotech, precision manufacturing and the machinery-equipment-metals cluster, medtech, watchmaking and a fast-growing data-centre cluster — where power quality protects product yield and capital equipment, not merely the energy bill. A scrapped GMP batch or a halted precision line costs far more than the power that caused it. Third, the generation mix: while supply is exceptionally low-carbon (hydro ~59.6%, nuclear ~28.4%), inverter-based solar PV is around 7.4% and climbing fast — and that rising inverter penetration raises harmonic distortion at exactly the low-voltage sites we serve.
What matters less in Switzerland is resilience. The grid is among the most reliable in Europe — around 21 customer-minutes lost per customer per year, with roughly 0.34 interruptions a year — so unlike sites in parts of Africa or the Gulf, Swiss operators are driven by cost, yield, capacity and compliance rather than by keeping the lights on.
The Solution
HarmoniQ installs a coordinated, solid-state system at the low-voltage switchboard — where Swiss sites carry their cost, where the cos φ reactive charge bites, and where the inverter-rising grid injects distortion. We deploy three products as the site requires: the HarmoniQ Booster for real-time power factor correction, the HarmoniQ Filter (HPF) for harmonic mitigation, and HarmoniQ Alpha as the integrated platform tying correction, filtering and voltage optimisation together. No switched-capacitor steps, no contactors, and no resonance risk with the harmonics already on your system.
Real-time true power factor correction to 0.98+ across the whole network — clearing the cos φ 0.9 threshold to remove the reactive-energy charge and cut demand and capacity fees, and freeing transformer headroom so you can add load without waiting for a grid-connection upgrade — especially valuable to the grid-constrained data centres around Zurich.
Active harmonic filtering that holds distortion within EN 50160 and IEC 61000 limits — the component that matters most as Switzerland’s solar PV and inverter penetration rises, protecting GMP-critical pharma process and tolerance-sensitive precision tooling.
Unifies correction, filtering and voltage optimisation across multiple boards or sites — stabilising voltage at the point of use to protect CNC, EDM, semiconductor and medtech tooling, with the visibility to prove power factor, reactive energy and demand at the meter, continuously.
Why not just install capacitor banks? + Read more− Close
Switched-capacitor banks correct power factor in fixed steps at the incoming feed — enough, in theory, to lift you over the cos φ 0.9 threshold at the meter. But they respond in steps and seconds, so they lag fast-changing loads; they sit only at the boundary, so reactive current still flows through your internal network; and on a system carrying harmonics — as nearly every modern Swiss site does, with its drives, rectifiers and inverters — a capacitor bank can form a resonant circuit with the supply, amplifying those harmonics.
HarmoniQ is solid-state and dynamic: it corrects continuously rather than in steps, works across the network rather than at one point, and carries no resonance risk. Paired with active filtering, it is power factor correction and harmonic mitigation designed for a plant full of drives and inverters, not the switchgear of forty years ago.
What It’s Worth
| Lever | What changes | Effect on the bill |
|---|---|---|
| Power factor → 0.98+ | Reactive energy clears the cos φ 0.9 threshold; demand and capacity fall | Reactive-energy charge removed; demand fees cut |
| Harmonic filtering to EN 50160 | Lower distortion, cooler transformers & cables; protected yield | Lower losses, less scrap and rework, longer asset life |
| Capacity release | Transformer / switchgear headroom freed | Defer or avoid a grid-connection upgrade — valuable around Zurich |
| Illustrative energy reduction | A 12–18% cut on a site of this size — a CHF 5 million bill is roughly CHF 600k–900k a year — plus the yield and capacity released | |
