🔗 New or bigger grid connection in Bulgaria: how long may it take and who do I complain to?

The short answer

A new home, a heat pump, a charging point or solar panels can need a new or bigger connection. The grid operator does this work, and many countries set deadlines and rules on costs.

📜 The rules in Bulgaria

Grid connection

For a rooftop or facade renewable system up to 30 kW, the grid company must issue its connection opinion within 20 days. Permits for solar systems up to 20 kW on buildings must be completed within one month.

  • A rooftop system only for your own use (up to twice your contracted power) needs only a notification to the grid company, which must send you a supplementary agreement within 14 days. You may feed power into the grid only after connecting as a producer. (me.government.bg)
  • For solar up to 20 kW, if the building authority does not decide in time, this counts as consent, as long as the system is not larger than your contracted power. (me.government.bg)

❓ Questions

Who pays for the connection?

Usually the customer pays a connection charge set by the grid operator or the regulator.

Why does my grid operator refuse or delay?

Sometimes the local grid is full. Ask for the reason and the expected date in writing.

Do I need a new connection for solar panels?

Often not for small systems, but you usually have to register them with the grid operator.
