What happens to surplus electricity
EAC now offers Net Billing for new PV connection applications. What the official notice confirms, and what still depends on your contract.

EAC — Net Billing and Virtual Net Billing, 31 December 2025Open the source — document in GreekThis is our explanation of a document written by someone else, and we can be wrong. It is not legal or tax advice: the decision is made by the authority.
A rooftop system rarely generates electricity at the same moment a home uses all of it. Electricity used in the building as it is generated is self-consumed. The rest is surplus, and the connection agreement determines how it is settled.
What EAC changed for applications from 2026
The Electricity Authority of Cyprus says that the previous own-consumption plan was extended until 31 December 2025. For customers who submitted a photovoltaic connection application from 1 January 2026 onwards, EAC Supply says it will offer only Net Billing and Virtual Net Billing agreements.
This is the clearest official date boundary currently published by EAC. It is based on the date of the connection application, not the installation date or the day an installer issued a quote.
What Net Billing establishes
Under Net Billing, imported and exported electricity are accounted for financially rather than offset one-for-one as units of energy. EAC's Net Billing Scheme page describes it as a scheme for generating electricity for own use and says that houses are among the eligible types of premises.
That makes the timing of consumption important. A kilowatt-hour used in the building while the panels produce replaces a kilowatt-hour that would otherwise be bought. A surplus kilowatt-hour sent to the grid is handled under the agreement instead.
Why this page gives no export price
The EAC notice confirms which agreement is offered, but it does not publish one universal export price on that page. We therefore do not put a made-up tariff into the savings calculation.
Before comparing payback figures, ask the supplier or installer to identify in writing:
- the agreement that will apply to the property;
- how exported electricity will be valued;
- which charges remain payable when electricity is exported;
- who submits the connection application and when.
If the system already has an agreement
The notice is explicitly about customers whose connection applications were submitted from 1 January 2026. It does not say that every earlier agreement is automatically rewritten. An existing owner should check the agreement attached to that installation rather than apply the new-applicant wording to it.
What the official notice does and does not prove
The notice proves the start date and the agreement types EAC offers to new applicants. It does not, by itself, establish a single export tariff, a payback period or the terms of an individual supplier contract.
Use this page as an explanation of the change, then open the EAC notice and the agreement offered for your own property before making a financial decision.
