Prosumer definition — legal criteria under OUG 163/2022

1. Legal definition

Under OUG 163/2022 (the Romanian Emergency Ordinance promoting the use of renewable-source energy), a prosumer is a final client who:

• Has a distribution contract with a DSO
• Produces renewable energy for own consumption
• Can inject surplus into the grid via a bidirectional meter

Different from an independent producer: the prosumer remains a client (not a commercial energy supplier), and the surplus is treated as in-kind compensation, not a sale.

2. Concrete criteria

To qualify as a prosumer in Romania 2026:

• Installed power ≤ 27 kWp for residential (≤ 100 kWp for three-phase systems with matching consumption)
• Photovoltaic system or another renewable (wind, micro-hydro — rare)
• Bidirectional meter installed by the DSO
• Prosumer connection contract + supply addendum

Casa Verde (the AFM subsidy) is NOT a required condition — you can be a prosumer without a subsidy, paying for the whole system yourself. For AFM context, see Casa Verde fast.

3. Who is and who isn't

Yes, you are a prosumer if: you have solar panels installed, a bidirectional meter, a signed connection contract — even if you only produce 100 kWh/month.

No, you are NOT a prosumer if: you have off-grid panels without a bidirectional meter (you're a pure self-consumer, legally fine but no compensation); you have a plug-in system under 800 W without a DSO contract (see balcony solar panels); you produce as a legal entity for sale (you become an independent producer — see the difference).
