The Cost of Power
Türkiye pairs a vast manufacturing economy with a regulated electricity tariff that climbs at almost every review. Business users paid around US$0.103 per kWh in September 2025, all-in — covering the cost of power, distribution and transmission, and every tax and fee. Because the lira figure is reset upward repeatedly — electricity inflation ran at roughly 83% over the year to April 2025 — the dollar price is the steadier way to read the cost, and it is the single biggest reason a factory, data centre or commercial estate should stop wasting any current.
The tariff is regulated and rises in steps. In its April 2025 review the energy regulator, EPDK, lifted retail prices again — households by 25%, public and private services by 15%, and industrial users by around 10% (about 5.8% for industry connected at medium voltage). Each increase is announced in lira, but the underlying dollar cost of a kilowatt-hour keeps the savings case intact regardless of where the exchange rate sits. Every percentage point of wasted current is charged at that rising unit rate.
| Who pays | Typical all-in price | Notes |
|---|---|---|
| Business / industry (all-in) | US$0.103 /kWh (TRY 4.770) | Sept 2025; incl. power, distribution, transmission and all taxes |
| Industry — April 2025 review | +10% (MV industry ~+5.8%) | One of several regulated increases through the year |
| Commercial / services | +15–17.5% (April 2025) | Commercial estates feel the regulated tariff as acutely as industry |
| Households (all-in) | ~US$0.060 /kWh (TRY 2.800) | Sept 2025; subsidised below a monthly consumption cap, so industry pays well above the household rate |
Business and household prices are from GlobalPetrolPrices (September 2025), shown in both Turkish lira and US dollars; the April 2025 percentage increases are EPDK regulated-tariff adjustments reported in the energy press. Prices are quoted in US$/kWh deliberately — lira figures are revised upward frequently under high inflation, so dollar values are more stable for comparison. Figures are current to GlobalPetrolPrices’ September 2025 collection and reviewed June 2026; they change at each regulated review — verify with EPDK (epdk.gov.tr) and your distribution company at the time of reading. All prices are unit rates and exclude site-specific demand and reactive charges.
How You’re Billed
The headline price per kWh is only part of the story. A metered Türkiye 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 (in kVA) and for the reactive energy it draws once that draw passes a set ratio of active energy. Those last two move directly when you correct power factor.
| Component | What it is | Cut by power quality? |
|---|---|---|
| Energy (active, kWh) | The active energy you consume, at the regulated or market price | Indirectly — lower network losses |
| Distribution & transmission | Network fees for delivering power over the grid | Partly |
| Taxes & levies | Energy fund, municipal and other statutory charges | No |
| Demand / capacity (kVA) | A charge on the apparent-power demand and connected capacity you place on the network | Yes — lower apparent power means a lower charge |
| Reactive-energy charge (kVArh) | A charge on reactive energy once inductive draw exceeds 20% of active energy (15% capacitive), for sites above 15 kVA | Yes — power factor correction cuts it directly |
So the answer to two questions Türkiye operators often ask: yes, you are billed for demand and capacity — through the apparent-power (kVA) charge — and yes, you are billed for poor power factor, through the reactive-energy charge once your inductive draw passes 20% of active energy. Both fall as power factor rises toward unity, which is exactly what correction delivers.
Power Factor & Regulation
Türkiye bills reactive energy on a clear, ratio-based rule rather than a single power-factor figure. For sites with installed power above 15 kVA — effectively every industrial and commercial connection, residential and lighting customers excepted — the reactive draw is metered against the active energy used. Once inductive reactive energy exceeds 20% of active energy (a ratio of 0.20, equivalent to roughly tan φ 0.20 or a power factor of about 0.98), or once capacitive reactive energy exceeds 15%, the excess is charged at the regulated reactive unit price. Smaller sites below 50 kVA are allowed a wider band — 33% inductive and 20% capacitive — but the principle is the same: draw too much reactive power and you pay for it. A motor- and drive-heavy plant running at 0.85–0.92 power factor therefore carries a recurring charge that disappears once it is corrected to 0.98+, alongside a lower apparent-power demand.
On harmonics and supply quality, Türkiye’s Service Quality Regulation for electricity distribution and retail sales (Official Gazette, 21 December 2012, no. 28504) obliges distribution companies to hold voltage quality within TS EN 50160 — which limits voltage total harmonic distortion to under 8% up to the 40th harmonic — and obliges connected users to keep current harmonics within the limits of IEEE 519. Compliance is assessed from a one-week, Class A measurement to IEC 61000-4-30, and a user who distorts the network beyond the limits and fails to correct it can be disconnected. As variable-speed drives, rectifiers, non-linear UPS and behind-the-meter solar multiply on Türkiye sites, staying inside those limits increasingly requires active harmonic filtering — not just a one-off survey.
The reactive-energy ratios (inductive > 20% / capacitive > 15% above 50 kVA; 33% / 20% below 50 kVA; applicable above 15 kVA) are set in Türkiye’s electricity tariff and distribution rules and applied by the distribution companies; voltage quality follows TS EN 50160 and current harmonics follow IEEE 519 under the Service Quality Regulation (Official Gazette 21 December 2012, no. 28504). Thresholds, the reactive unit price and harmonic limits are updated periodically — verify the current values with EPDK (epdk.gov.tr) and your distribution company before relying on them.
Why Power Quality Matters Here
Three structural forces make power quality a Türkiye boardroom issue, not just an engineering one. First, the tariff — already covered, regulated upward at almost every review and read most reliably in dollars. Second, the generation mix: low-carbon sources supplied around 45% of Türkiye’s electricity in 2024 — hydro near 22%, wind around 11% and solar around 7.5%, with wind and solar together reaching a record 18% (Ember, Türkiye Electricity Review 2025) — and that fast-growing, inverter-heavy supply raises harmonic distortion and reactive-power volatility at exactly the commercial and industrial sites we serve. Third, growth and capacity: demand and connected industry keep expanding, and freeing transformer and switchgear headroom on the connection you already have lets a growing or electrifying site add load without waiting on a network upgrade.
Resilience matters more here than on the grids of north-west Europe. Supply interruptions, while improving, remain longer and more frequent in Türkiye than in the most reliable European systems — so alongside cost, charges and compliance, clean and stable power at the switchboard also protects sensitive production and data loads from the disturbances a weaker grid can pass through.
The Solution
HarmoniQ installs a coordinated, solid-state system at the low-voltage switchboard — where Türkiye sites carry their cost, where the reactive-energy and kVA charges bite, and where the inverter-heavy 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 — holding inductive reactive draw below the 20% ratio to remove the reactive-energy charge and cut apparent-power (kVA) demand, and freeing transformer headroom so you can add load without a slow network upgrade.
Active harmonic filtering that holds distortion within TS EN 50160 and IEEE 519 limits — the component that matters most in Türkiye’s high-inverter environment, where drives, rectifiers, non-linear UPS 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 hold you under the reactive ratio 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 Türkiye site does, with its drives, rectifiers and inverters — a capacitor bank can form a resonant circuit with the supply, amplifying those harmonics. Overcorrection can also tip you into the capacitive charge band, which is penalised at a tighter 15% ratio.
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+ | Inductive reactive draw clears the 20% ratio; apparent-power demand falls | Reactive-energy charge removed; kVA demand cut |
| Harmonic filtering to TS EN 50160 / IEEE 519 | Lower distortion, cooler transformers & cables | Lower losses, longer asset life, no disconnection risk |
| Capacity release | Transformer / switchgear headroom freed | Add load on the connection you already have |
| Indicative annual saving | A material recurring sum on a site of this size — plus the capacity released | |
