Green electricity tariffs rise by up to 76% – How charges are set

A new round of increases in electricity bills is being driven by higher green tariff charges for November, as the first announcements by suppliers show increases of as much as 76%. In several cases, the new charges now range between 26 and 36 cents per kilowatt-hour, placing a significant additional burden on households that remain on variable-rate plans.

This development comes at a time when the energy market is under intense pressure, with natural gas trading at around €100/MWh and the wholesale electricity price standing at €312.72/MWh for November 2, up 19.37% on the day.

The higher cost in the energy market is now being reflected in suppliers’ tariff offerings, with consumers facing significantly higher charges.

Increases of up to 76% by suppliers

According to the price lists announced so far, Protergia is raising the green residential tariff “Protergia Οικιακό Value Special” by 43%. The charge rises from 18.4 cents to 26.4 cents per kilowatt-hour.

HERON is making an even larger adjustment. Its green “ΗΡΩΝ Basic Home” plan, after several months during which the charge had remained at 14.76 cents per kilowatt-hour, is now priced at 25.95 cents.

A significant increase is also recorded in NRG’s green tariff, where the charge rises by 29%, from 25.9 cents to 33.4 cents per kilowatt-hour. Similarly, Volton has announced a 32% increase, with the price rising from 27.36 cents to 36.22 cents per kilowatt-hour.

These first announcements point to a particularly costly picture for November’s green tariffs, with charges moving to markedly higher levels compared with the previous month. The differences between companies are significant, but the overall trend is the same: increases in the wholesale market are now being passed through, to varying degrees, to consumers’ final charges.

PPC’s approach and consumers’ options

The picture is different for PPC’s green tariff. The company announced an increase of just 6.2%, setting the G1/G1N charge at 16.9 cents per kilowatt-hour, up from 15.913 cents in October. The company is applying an 88.3% discount to the nominal charge, absorbing most of the increase in the wholesale market.

At the same time, it is keeping the price of its blue fixed-rate myHome Online plan at 13 cents per kilowatt-hour, giving consumers the option of securing a fixed charge and greater predictability in their electricity bills.

This situation highlights the importance of tariff choice, as the large differences in charges can significantly affect the final electricity cost for a household. It is no coincidence that suppliers are increasingly shifting their commercial strategy towards fixed-rate blue tariffs, which offer protection against fluctuations in the wholesale market.

More than half of consumers remain on green tariffs

Despite the growing promotion of fixed-rate plans, green tariffs continue to account for the largest share of household consumers. According to RAAEY data for August, 3,087,208 household electricity supply points are on special or green tariffs, representing 51.79% of the retail market.

Fixed-rate or blue tariffs account for 1,885,702 household supply points, or 31.63%, while yellow variable-rate tariffs account for 988,383 meters, corresponding to 16.58% of the market.

PPC’s position in the retail electricity market is also particularly significant. Across low-voltage supply points, the company has approximately 5.4 million meters, giving it a market share of 71.34%. It is estimated, moreover, that PPC’s customer base also includes the largest number of household consumers who remain on green tariffs.
