What happened
Türkiye’s provisional day-ahead electricity market-clearing average for delivery on 17 September 2026 has been calculated at TL3,203.65/MWh. The prices relate to the spot market operated by Energy Exchange Istanbul (EPİAŞ), according to Enerji Günlüğü’s compilation of EPİAŞ data.
The result represents a marked increase from the preceding delivery day’s average of TL2,858.11/MWh: the published comparison puts the change at 10.79%. Against the same weekday one week earlier, the daily average is 0.52% higher.
Hourly prices show a substantial spread. The highest published value is TL4,149.99/MWh for 19:00–20:00, while TL2,099.98/MWh is scheduled for 12:00–13:00. Market participants with exposure to the day-ahead market should review their positions around the evening interval, when the delivery-day price is highest.
Why it matters
The provisional average signals higher short-term wholesale power costs than those recorded for the previous day. For electricity buyers, generators and other parties whose settlement or procurement is linked to Türkiye’s spot market, the hourly profile is as relevant as the all-day figure.
The 08:00–20:00 peak window has an average of TL3,248.75/MWh, above the overall daily result. Outside that period, the reported average is TL3,158.55/MWh. The difference indicates that the higher-cost hours are concentrated within the defined peak period, particularly in the evening.
These are provisional market-clearing figures, rather than a finalised tariff or a retail electricity price. They should therefore be read as delivery-day spot-market indicators.
What to watch next
The stated hourly and average values apply to electricity delivered on 17 September 2026. Buyers and traders can compare the realised delivery-day outcome with the provisional schedule, while monitoring subsequent EPİAŞ market data for any changes in the short-term price pattern.
Enerji Günlüğü reported that, for the preceding day, the maximum hourly price was TL4,134.63/MWh and the minimum was TL1,600.01/MWh, both occurring in the same respective 19:00–20:00 and 12:00–13:00 slots. That comparison underscores the increase in the next day’s published minimum as well as its average.
