The Cost of Power
Romania pairs a fast-growing manufacturing economy with electricity that is already expensive and climbing hard. Non-household prices reached €0.1511 per kWh excluding taxes in the second half of 2025 — below the EU average of €0.1837 ex-tax, but rising +15.4% year-on-year, the single steepest increase of any EU member state. All-in, a business pays closer to ~€0.20/kWh (about RON 1.0/kWh). For a factory, data centre, or commercial estate, the price of a kilowatt-hour is the single biggest reason to stop wasting any — and it works harder against you every year.
Romania completed the liberalisation of its electricity market through 2025, and the regulated price caps that once held bills down have unwound. The result is a tariff that no longer offers the cheap-power comfort it once did — so the argument that “power is cheap here, efficiency doesn’t move the needle” simply does not hold. Every percentage point of wasted current is charged at a rate that rose 15% in a single year.
| Who pays | Typical price | Notes |
|---|---|---|
| Non-household — ex-tax | ~€0.1511/kWh (H2 2025) | ~RON 0.77/kWh; below the EU average of €0.1837, but rising +15.4% YoY — the EU’s steepest |
| Non-household, medium (incl. non-recoverable tax) | ~€0.14/kWh (Dec 2024) | ~RON 0.71/kWh; where most qualifying mid-commercial sites sit |
| Business / SME (all-in) | ~€0.207/kWh (Sep 2025) | ~RON 1.06/kWh; the number a CFO actually sees on the bill |
| Households (incl. taxes & levies) | ~€0.29/kWh (H2 2025) | ~RON 1.4/kWh; up ~58.6% on H2 2024 after price caps unwound |
Non-household ex-tax and the +15.4% trajectory are from Eurostat (H2 2025); the medium-consumer rate is the Eurostat figure for December 2024; the business/SME all-in figure is from GlobalPetrolPrices. The household figure (~€0.29/kWh, ~RON 1.4/kWh, all taxes included, H2 2025) is the Eurostat household price reported via Romania-Insider and is web-sourced rather than drawn from internal data — treat it as indicative. Euro figures are converted to RON at roughly RON 5.1 to the euro (2026). Figures are current as of 2024–2025, date-stamped June 2026, and are revised regularly — verify against Eurostat electricity prices and ANRE at the time of reading. Prices are per kWh and exclude site-specific demand and capacity charges.
How You’re Billed
The headline price per kWh is only part of the story. A metered Romanian site pays for the energy itself, for the networks that deliver it, for taxes and levies — and, critically for power quality, for the apparent-power demand 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 after market liberalisation | Indirectly — lower network losses |
| Network charges | Distribution and transmission fees for delivering power over the grid | Partly |
| Taxes & levies | Non-recoverable taxes and other regulated charges | No |
| Demand / capacity charge (kVA) | A charge on the apparent-power demand and capacity you place on the network | Yes — lower apparent power means a lower charge |
| Reactive-energy charge (kVArh / MVArh) | An ANRE charge on inductive reactive energy drawn once power factor falls below 0.92 (~€1.4/MVArh, ~RON 7/MVArh) | Yes — power factor correction cuts it directly |
So the answer to two questions Romanian 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 ANRE reactive-energy charge once you slip below a 0.92 power factor. Both fall as power factor rises toward unity, which is exactly what correction delivers.
Power Factor & Regulation
Romania bills reactive energy on a clear, quantifiable rule set by the national regulator, ANRE. Inductive reactive energy drawn at a power factor below 0.92 — equivalent to a tan φ above 0.4843 — is billed at ANRE’s hourly rates, averaging roughly €1.4/MVArh (about RON 7/MVArh), and rising to as much as three times that below lower thresholds, applied to consumers on smart metering. 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 apparent-power demand fees.
On harmonics and supply quality, Romania applies the EU framework: connections must hold voltage quality within EN 50160 and manage harmonic emissions under the IEC 61000 series, with equipment placed on the market under CE marking (the Low Voltage Directive 2014/35/EU and EMC Directive 2014/30/EU). Connection follows ANRE technical norms and Transelectrica / distributor rules — including a tighter grid-capacity-allocation procedure that is lengthening connection queues. As variable-speed drives, rectifiers and behind-the-meter solar multiply on Romanian sites, staying inside those limits increasingly requires active harmonic filtering — not just a one-off survey.
The reactive-energy charge below a 0.92 power factor (tan φ > 0.4843) is set by ANRE and billed at hourly rates (~€1.4/MVArh average, rising up to 3× below lower thresholds) for smart-metered consumers; voltage-quality limits follow EN 50160 and harmonic emissions follow the IEC 61000 series, with equipment CE-marked under the Low Voltage and EMC Directives. The exact charge, threshold and connection rules vary and are updated periodically — confirm the figures that apply to your connection with ANRE, Transelectrica and your distributor and supplier before relying on them.

Why Power Quality Matters Here
Three structural forces make power quality a Romanian boardroom issue, not just an engineering one. First, the tariff — already covered, and rising faster than anywhere else in the EU. Second, the generation mix: Romania’s grid is notably clean, around 65% low-carbon in 2024 (hydro ~22%, nuclear ~19%, wind ~11%, solar ~4%), with about 15% of generation from wind and solar and roughly 5 GW of new solar expected by 2030 — and that growing inverter-based supply raises harmonic distortion and voltage volatility at exactly the commercial and industrial sites we serve. Third, capacity: Romania flipped to a net electricity importer in 2024, and Transelectrica’s tighter grid-capacity-allocation procedure is lengthening connection queues — so freeing transformer and switchgear headroom on the connection you already have lets a growing or electrifying site add load without waiting for the grid.
What matters less in Romania is resilience. The grid is reasonably reliable by regional standards — around 74.6 customer-minutes lost per customer per year (SAIDI), with a SAIFI of about 2.29 in 2024 — so unlike sites in parts of Africa or the Gulf, Romanian operators are driven by cost, charges, 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 Romanian sites carry their cost, where the ANRE sub-0.92 reactive charge bites, and where the growing inverter base 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 0.92 threshold to remove the ANRE reactive-energy charge and cut apparent-power demand fees, and freeing transformer headroom so you can add load without waiting in a lengthening grid-connection queue.
Active harmonic filtering that holds distortion within EN 50160 and IEC 61000 limits — the component that matters more each year in Romania’s rising-inverter environment, where drives, rectifiers and on-site solar all push harmonic levels up.
Unifies correction, filtering and voltage optimisation across multiple boards or sites — with the visibility to prove power factor, reactive energy and apparent-power 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 0.92 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 Romanian 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 0.92 threshold; apparent-power demand falls | ANRE reactive-energy charge removed; demand fees cut |
| Harmonic filtering to EN 50160 | Lower distortion, cooler transformers & cables | Lower losses, longer asset life |
| Capacity release | ~15–20% of transformer / switchgear headroom freed | Add load without waiting in a tightening grid-connection queue |
| Indicative annual saving | A material recurring sum on a site of this size — in RON, and growing with the tariff — plus the capacity released | |
