1. It applies to all categories of consumers (residential, commercial, farmers, Local Authorities, Energy Communities).
2. Under net-billing, the offsetting of the energy produced against the energy consumed takes place in real time. Any surplus energy is injected into the grid and compensated for twenty years based on the wholesale market price during the hours when it is injected.
3. A special “Residential Photovoltaics” program has been established for the installation of photovoltaic stations with an installed capacity of up to 10,8 kW, using simultaneous or virtual simultaneous offsetting exclusively for residential consumers (households).
4. Residential self-consumers are not considered business operators and are not subject to tax obligations for the disposal of the energy they produce and inject under the offsetting arrangement.
5. Specifically for the Non-Interconnected Islands (NII), because there is no organized market, surplus energy is paid to the self-consumer at a price (€/MWh) equal to the Special Market Price (SMP) for RES & CHP technologies, as published by DAPEEP. It is settled by the NII Operator (HEDNO S.A.) in each NII electricity system, in accordance with the provisions of the NII Code.
6. Collective self-consumption at building level is provided for, using virtual net-billing. At least two (2) self-consumers located in the same building may jointly participate in activities and agree among themselves on how to allocate the energy produced by their stations, subject to applicable network charges and other related charges, fees, contributions and taxes. Under virtual net-billing within a collective self-consumption scheme, common-area consumption in buildings may also be included.
7. For simultaneous net-billing and zero feed-in, the capacity of each generating station installed may be up to one hundred percent (100%) of the agreed consumption capacity (in kVA). For virtual net-billing, the capacity of each generating station installed may be up to one hundred percent (100%) of the installed capacity of all the consumption being offset.
8. The self-consumer’s station may be owned by the self-consumer or a third party, or its installation and operation—including metering and maintenance—may be managed by a third party, provided that the third party remains under the self-consumer’s direction. In this case, the third party is not considered a self-consumer. If the self-consumer’s station is installed by a third party rather than by the self-consumer, any financial benefit from surplus energy under simultaneous or virtual simultaneous net-billing, if compensated, accrues exclusively to the self-consumer.
9. The self-consumer or the third party that owns the station may enter into bilateral power purchase agreements (PPAs) for surplus energy in cases of simultaneous net-billing where the energy is paid for by the market. Similarly, the Supplier or the Aggregator may guarantee a fixed sale price for surplus energy.
