Greek electricity tariffs: green rise, gas surge surge, price spik

RAAEY’s monitoring shows the variable “yellow” tariff stayed the cheapest for a typical 300 kWh household in the Jan‑July 2026 period, averaging €49.99 per month, while the fixed “blue” contract rose to €55.86 and the “green” tariff hovered around €56.00. The market mix remained dominated by green contracts (≈ 54 % of households), with blue at about 31.5 % and yellow near 14 %. July’s European natural‑gas market shock deepened, with TTF futures jumping roughly 35 % to €59.3 /MWh after the U.S.–Iran confrontation escalated in early July. Storage levels fell to about 56 % of capacity, heightening concerns over winter supply and adding pressure to electricity prices across the continent, including Greece. In August, Greece’s green electricity tariffs rose 8 % to 18.8 cents/kWh (from 17.4 c/kWh). Supplier rates varied: DEI at 13.8 c/kWh (15.4 c/kWh above 200 kWh), IRON 14.7 c/kWh, Protergia 16.9 c/kWh, NRG 20.9 c/kWh, ZENITH 30.3 c/kWh, and ELIN 18.8 c/kWh. The day‑ahead wholesale price climbed 18.3 % month‑on‑month to €109.95/MWh, though the three largest suppliers kept lower rates, tempering the impact on household bills. Renewable generation continued its upward trend, reaching 54.8 % of the mix in June, while total generation rose 7.5 % and demand fell 3.5 %. Exports surged 55 % to 847 GWh, making Greece a net electricity exporter. The combined effect of volatile gas prices and rising green tariffs underscores On 3 August 2026 the sensitivity day‑ahead wholesale price on the Energy Stock Exchange jumped 57.5 % to €153.96/MWh, after an 18.3 % month‑on‑month rise in July. Intraday prices swung from a low of Greek electricity costs €0.01/MWh to broader a peak near €300.86/MWh, reflecting heightened volatility while European energy market dynamics. gas prices stayed around €59‑60/MWh. Renewable sources supplied roughly 55 % of generation that day, with gas‑fired plants providing about 29 %.
