KEY POINTS

  • Tiered natural gas pricing began on April 4, 2026.
  • Exceeding the monthly limit means the entire consumption is billed at the higher Tier-2 rate.
  • Istanbul's November limit is 101.71 cubic meters; Kocaeli's is 102.85 cubic meters.
  • Tax-included prices are 17.79 lira for Tier-1 and 26.73 lira for Tier-2 per cubic meter.
  • About 2.8 million of 21.8 million subscribers are directly affected.

A tiered natural gas pricing model took effect on April 4, 2026, and November marks its first major winter test. Turkey's Energy Market Regulatory Authority set provincial consumption limits based on average usage over the past five years. BOTAŞ announced that November limits vary by city according to climate and consumption habits.

Households that stay within their Tier-1 limit pay the lower rate, while those who exceed it pay Tier-2 prices on their entire monthly consumption. BOTAŞ rules state that only the excess amount is not charged at the higher rate; the full volume is billed under Tier-2.

In Istanbul, the November limit is 101.71 cubic meters. A household using 101.70 cubic meters pays Tier-1 prices, but consumption of 102 cubic meters means the entire amount is charged at the Tier-2 rate. BOTAŞ wholesale prices are 10.625 Turkish lira per cubic meter for Tier-1 and 18 lira for Tier-2, excluding taxes.

Retail prices include distribution fees, special consumption tax, and value-added tax. With taxes, Özgür Kocaeli reports Tier-1 costs 17.79 lira per cubic meter and Tier-2 costs 26.73 lira. The state currently subsidizes more than half of household bills, covering 500 lira of a 1,000-lira bill.

Subsidies will end for households that exceed their tier, creating a risk that bills could double overnight. The system affects about 2.8 million subscribers, roughly 12 percent of Turkey's 21.8 million natural gas customers. Support for 19 million households will continue.

Kocaeli's November Tier-1 limit is 102.85 cubic meters, while its December limit is 200.57 cubic meters. Experts recommend maintenance and insulation steps that could reduce consumption by 15 to 20 percent.
