What Is a Reactive Energy Penalty?

In short: In Turkey, the reactive energy penalty is the “Reactive Energy Charge” added to the distribution bill when the ratio of inductive or capacitive reactive energy to active energy in the billing period exceeds the legal limit. For an installed capacity of 50 kVA and above, the limit is 20% inductive and 15% capacitive. Once the limit is exceeded, all reactive energy of the period is charged, at 3.493698 ₺/kVArh from 4 April 2026.

What Is Reactive Energy?

Power in electrical systems has two components: active power (kW), which does useful work, and reactive power (kVAr), which flows back and forth between the grid and the load to build the magnetic field of motors and transformers. Reactive power does no work but loads cables, transformers and the grid, and increases losses.

Coil-type loads (motors, compressors, transformers) draw inductive reactive energy. Capacitors produce capacitive reactive energy; a compensation panel is installed to balance the two.

2026 Reactive Penalty Rates and Limits

The quantity checked is the ratio of reactive energy to active energy in the billing period. The limit has two tiers based on installed capacity:

The reactive energy unit price applies in two periods in 2026:

The inductive and capacitive ratios are checked independently. If both are exceeded in the same month, both items are billed separately.

Who Pays the Reactive Penalty, and Who Is Exempt?

The reactive energy charge applies to three-phase subscribers such as industry, commercial premises and agricultural irrigation. The reactive energy tariff does not apply to:

• Residential subscribers
• Lighting subscribers
• Single-phase subscribers
• Subscribers with a connection capacity of 9 kW or less

Where Are the Reactive Values on the Bill and the Meter?

The bill shows the “Reactive Energy Charge” as a separate line; inductive and capacitive quantities appear in the meter index section. On an electronic meter the inductive value is read under code “Ri” (OBIS 3.8.0 / 5.8.0) and the capacitive value under “Rc” (OBIS 4.8.0 / 8.8.0). For sites within OSOS scope, the same values can also be followed on the distribution company's OSOS portal.

Example: How Is the Reactive Charge Formed? (2026)

Suppose a business with an installed capacity above 50 kVA sees 250,000 kWh of active and 62,000 kVArh of inductive reactive energy on its May 2026 bill:

1. Inductive ratio: 62,000 ÷ 250,000 = 24.8%. The limit is 20%, so it is exceeded.
2. Once the limit is exceeded, all inductive reactive energy of the period is charged: 62,000 kVArh.
3. Charge: 62,000 × 3.493698 ₺ = approximately 216,609 ₺ (excluding VAT and levies).
4. Comparison: if only the 12,000 kVArh above the limit were charged, the amount would be approximately 41,924 ₺.

Even a small overshoot causes all reactive energy to be billed. To run the calculation with your own bill values, use the reactive penalty calculator.

Most Common Causes of Reactive Penalties

Motors and compressors: The largest inductive load in industrial facilities. Large motors running at partial load noticeably lower the power factor.

HVAC and chillers: Chillers and air handling units raise the reactive ratio, especially during partial-load periods at season transitions.

Lightly loaded transformers: Distribution transformers running at light load continuously draw reactive energy due to magnetising current.

Over-compensation: Capacitors left connected during low-load periods such as nights, weekends or holidays push the capacitive ratio over the limit.

Compensation faults: A blown fuse, a capacitor that has lost capacity, a wrongly set reactive power relay or too few steps cause penalties even when a panel exists.

Compensation: Preventing the Reactive Penalty

The basic way to prevent the reactive penalty is power factor compensation. The capacitor banks in the compensation panel supply inductive reactive power locally, so less reactive energy is drawn from the grid. In automatic panels, the reactive power relay switches steps in and out as the load changes. In facilities with a high harmonic load, capacitors must be selected with detuning reactors; see our article on harmonic distortion for details.

How to Check the Reactive Charge on Your Bill

Divide the inductive and capacitive quantities on the bill by the active energy to calculate the ratio yourself. Check which tier (below or above 50 kVA) your installed capacity is assessed in and that the correct unit price for the period is used. If you see a discrepancy between the meter indexes and the bill, you can apply in writing to your supplier or distribution company together with the meter readings.

Tracking the Reactive Penalty with Argus EMS

A compensation panel is the physical solution; without monitoring, whether the panel works properly only becomes clear when the bill arrives. Argus EMS:

• Periodically reads active and reactive energy from the transformer or energy analyser
• Calculates the cumulative inductive and capacitive ratio since the start of the month
• Sends an e-mail warning when the ratio approaches the limit
• Makes compensation faults visible at sites where it can read step status from the reactive power relay

This way a compensation problem is noticed and handled within the month, before the bill is issued.
