The ‘green’ electricity bills for November, announced by the suppliers and published by the Regulatory Authority, are up to three times higher than the fixed ‘blue’ rates. Even the cheapest ‘green’ tariff costs almost twice as much as the PPC’s fixed tariff, which this month is the cheapest on the market at 13 lepta per kilowatt-hour.
The difference increases for those who use a lot of electricity. Many ‘green’ tariffs have two tiers: the lower rate applies only if monthly consumption remains below a threshold set by the supplier, usually between 100 and 200 kilowatt-hours. If you exceed this, all consumption, from the very first kilowatt-hour, is charged at the higher rate. For November, the higher rate on green tariffs starts at 26 lepta and goes up to 40 lepta per kilowatt-hour.
What does this mean for an account?
A house heated by air conditioning easily exceeds 350 kilowatt-hours a month in winter. For 350 kilowatt-hours, the supply charge alone – excluding the standing charge, variable charges and taxes – amounts to:
- at 13 minutes (DEH standard tariff): 45.50 euros
- at 26 minutes (cheapest green tariff above the threshold): 91 euros
- at 40 cents (most expensive green tariff): 140 euros
The difference between the cheapest and the most expensive tariff is almost 95 euros a month for the same electricity supply.
Why did they go up?
The price of natural gas on the European market has exceeded 100 euros per megawatt-hour. Along with this, the wholesale price of electricity on the Greek energy exchange rose to 197.07 euros per megawatt-hour in October, up from 156.31 euros in September. Green electricity tariffs follow the wholesale price with a one-month delay, which is why the October increase is reflected in November’s bills.
Nevertheless, most households have not switched to a different tariff. According to the latest figures from the Regulatory Authority for August, 51.79 per cent of domestic meters were on the green tariff, 31.63 per cent were on a fixed ‘blue’ tariff and 16.58 per cent on a ‘yellow’ tariff. In September and October, there were many fixed tariffs available for less than 15 lepta.
Colours, in a nutshell
- Blue: fixed price for the entire duration of the contract.
- Green: variable price, announced on the first day of each month.
- Yellow: a variable price, calculated at the end of the month based on the wholesale price.
How to compare and how to change
The Regulatory Authority has a free comparison tool at energycost.gr, where you can enter your consumption and see the total cost per bill, including the standing charge. Compare the total cost, not just the price per kilowatt-hour, and check whether the fixed charge includes an early termination clause.
The new supplier will handle the switch. You’ll need your supply number from your latest bill, your ID and your tax registration number. Your electricity supply won’t be cut off and you’ll keep the same meter. If you stay with the same supplier, you can simply ask to switch to their standard tariff.
Those who heat their homes using electricity can also apply for the electricity heating allowance via the mυΘέρμανση app, unless they are on the Social Household Tariff.
