Government Subsidy on Electricity - Frequently Asked Questions

The Government announced the implementation of a state subsidy / discount, due to the unprecedented increase in the cost of electricity, to all customers of low voltage electricity (all uses), including special tariffs (eg CTO), which are contracted to floating tariffs with a provision for a price adjustment clause, regardless of the provider from which electricity is supplied.

All customers of low voltage electricity (all uses), including special tariffs (eg CTO) which are contracted in floating tariffs with a provision for a price adjustment clause.
The state subsidy is provided for the period of consumption from 1/9/2021 to 31/12/2021, even retroactively, a period which can be further extended by a Government decision.

The amount of the state subsidy amounts to 0.03 € / kWh (or 30 € / MWh) for a maximum subsidized limit of 300 kWh of monthly consumption for 30 days, ie for 10 kWh per day.

The state subsidy will apply only to Protergia electricity clearance bills, until the time period in which it relates is fully cleared. It will appear as a discrete credit in the field of competing charges entitled "Energy Transition Fund Credit" and as a product of consumption on the subsidy in € / kWh (eg 300 kWh * 0.03 € / kWh = 9 €)

The state subsidy will be applied by all electricity suppliers, based on the same criteria & conditions as those set by the Ministry of Energy and Environment.


The state subsidy will be applied retroactively for consumption from 1/9/2021 to 31/12/2021, and is valid for the days when the customer was contracted with Protergia in a floating invoice with provision for a price adjustment clause, according to its guidelines. Ministry of Energy and Environment.

For any period that the customer was contracted with Protergia in a non-fluctuating tariff without provision of a price adjustment clause, the subsidy is not applied for this period, according to the guidelines of the Ministry of Energy and Environment.

The state subsidy also applies to CTO customers, for as long as they were contracted with Protergia on a floating tariff with a price adjustment clause.

Protergia, in addition to the state subsidy, also offers discounts based on the respective invoice or its promotional, which you can see in detail on our website.

Protergia electricity bills are issued on a monthly basis and belong to one of the following types: ESTIMATED -> Based on an estimated consumption level. ACTUAL -> Based on the consumption measured and certified by the Distribution Network Operator.. ACTUAL – CUSTOMER READING -> Based on the “Registration of Meter Readings” service.
If for any reason the consumption is measured at a time interval that is longer or shorter than four months, then the consumption charged is adjusted relative to the four-month period by applying the “billing period adjustment factor” (actual consumption days / 120 days).
Competitive charges comprise the following: The charge for the supply of power under the Day Ahead Scheduling mechanism, the charges of the Uplift Accounts (UA-2, UA-3), charges for losses in the Hellenic Electricity Distribution Network, the charge based on the weighted average production cost of conventional thermal plants (Charged to the Special Account of article 143 of Law 4001/2011) and the costs of the Transitional Capacity Assurance Mechanism (MMDEI), as defined in the Electricity Transaction Code (Decision 56/2012 of the Regulatory Authority for Energy, published in Government Gazette issue 104/B/2012) and determined in accordance with the laws in force.

These are increases or decreases in Supply Charges in case of a marked change in the cost of electricity.
They may be triggered based on predetermined limits and variables provided for in Article 8.8 of the General Conditions of Contract. According to Article 8.8: Supply Charges are calculated as follows: If the sum of (I) the average System Marginal Price; (II) the average unit charges for the uplift accounts; and (III) the weighted average production cost of conventional power plants during the Consumption Period; plus the applicable rate for network losses on (I) through (III) (hereinafter the “Average Uplifted Sum”) is between €40 and €50/MWh, there is no increase or decrease in Supply Charges. If the Average Uplifted Sum during the consumption period is under the €40/MWh limit, supply charges are decreased by the difference between the €40/MWh and the Average Uplifted Sum. If the Average Uplifted Sum during the consumption period is over the €50/MWh limit, supply charges are increased by the difference between the Average Uplifted Sum and the €50/MWh limit. Such increases or decreases of the Supply Charges will appear as distinct charges or credits on the bills the Supplier sends to the Customer, when actual data are made available by the operator. This General Condition does not apply for the first six months after the Supplier has activated the representation authorisation for the Site meter. Protergia may charge or credit customers depending on the amount at which the above sum closes. Uplifts pursuant to Article 8.8 are only included on settlement bills featuring electricity consumption.
The Social Residential Tarrif or the Vulnerable customer may settle his entire debt in installments and interest-free installments according to the following:
  • Each monthly installment shall not exceed 50% of the corresponding monthly  Electricity Expenditure of the Vulnerable Customer.
  • The above option does not relieve the Customer of his responsibility for timely payment of his debts to the Supplier
  • In order for the settlement to take effect, the first dose must be paid within 5 days
