A new timing point in Turkey's 2026 electricity rules arrives on 1 October. EPDK says a residential account that was below the annual limit in 2025 but first passed 4,000 kWh in 2026 by the hourly meter reading at 23:59 on 31 July is to be billed under the high-consumption Last Resort Supply Tariff from 1 October if it has no bilateral supply agreement. The change is account-specific; it is not a nationwide increase for every home.
Who can enter the tariff on 1 October
The October example applies to homes whose 2025 consumption stayed below 4,000 kWh and whose cumulative 2026 consumption first exceeded 4,000 kWh at the 31 July hourly reading. EPDK's general rule is that a customer enters the high-consumption tariff on the first day of the third month after the month in which the limit is reached. Homes that crossed at another time can therefore have a different start date.
The limit is annual, not a monthly allowance
The residential threshold is 4,000 kWh per calendar year. Dividing it by 12 gives about 333 kWh a month, but this is only a planning average: one high summer month does not by itself decide the outcome. The supplier assesses cumulative consumption and the applicable meter-reading date.
What changes on the bill
The distribution charge remains the same for the same subscriber class, while the active-energy component becomes market-linked. EPDK says that component is based on the average market clearing price plus the average YEKDEM renewable-support cost, increased by a 5% coefficient for residential consumers. Taxes continue to apply under the existing rules, so there is no single fixed nationwide increase to quote in advance.
Why villas and long summer stays need attention
Air conditioning, pool pumps, electric water heating and extended occupancy can push annual use higher. Foreign residents and long-stay tenants should check the cumulative kWh line and tariff description on the bill rather than assume the rent includes a fixed electricity rate. If the property or subscriber recently changed, ask the authorised supplier how the consumption point is classified.
There is no obligation to sign a private contract
Consumers above the limit may make a bilateral agreement with a licensed supplier, but EPDK says this is not compulsory. Without one, the regional incumbent supplier continues service automatically under the Last Resort Supply Tariff. Any private offer should be compared by unit price, duration, early-exit terms and whether the quoted discount is fixed or market-linked.
Turkey Compass fact check
Confirmed: 4,000 kWh is the 2026 residential annual limit, EPDK estimates roughly 2.5 million homes — about 6% of residential subscribers — are affected, and the October example concerns customers crossing the threshold by the 31 July reading. Incorrect: every household receives the same electricity increase on 1 October. Consumers can compare an eligible bill with EPDK's official calculator.
